Description

Technical Field

[0001] This disclosure relates to the field of intelligent education technology, and in particular to an online learning method, apparatus, device, and medium. Background Technology

[0002] In digital education methods for students, intelligent recommendations of practice exercises can be provided for questions that students answered incorrectly or for questions that require special attention, enabling students to conduct targeted reinforcement training for weak areas of knowledge.

[0003] Currently, when developing educational software (or clients) that supports online learning, various education service providers typically adopt a model that integrates online intelligent recommendation of practice questions as a feature of their own software. This means that the intelligent recommendation function is closely coupled with the educational software, and the recommendation of practice questions is entirely supported and maintained by their own backend database, which significantly increases the cost of software development. Summary of the Invention

[0004] To address, or at least partially address, the aforementioned technical problems, embodiments of this disclosure provide an online learning method, apparatus, device, and medium.

[0005] In a first aspect, embodiments of this disclosure provide an online learning method applied to a client that supports online learning, the method comprising:

[0007] The system receives at least one recommended practice question sent by the education provider's server and displays it for the user to answer.

[0008] Secondly, this disclosure also provides an online learning method applied to an education provider server, the method comprising:

[0009] The system receives a question recommendation request from a client based on the user's question-answering needs, and then sends the question recommendation request to a question recommendation server; wherein, the question recommendation request is used to request the question recommendation server to provide at least one recommended practice question that meets the user's question-answering needs;

[0010] The at least one recommended practice question fed back by the practice question recommender server is sent to the client so that the client can display the at least one recommended practice question.

[0011] Thirdly, this disclosure also provides an online learning method applied to a question recommendation server, the method comprising:

[0012] Receive a question recommendation request sent by the education provider server; wherein, the question recommendation request is sent by the client to the education provider server based on the user's question-answering needs;

[0013] Based on the exercise recommendation request, at least one recommended exercise question that meets the user's answering needs is determined and sent to the education provider server, so that the education provider server can send the at least one recommended exercise question to the client and display the at least one recommended exercise question through the client.

[0014] Fourthly, embodiments of this disclosure also provide an online learning device configured on a client that supports online learning, the device comprising:

[0015] The exercise recommendation request sending module is used to send an exercise recommendation request to the education provider server based on the user's answering needs; wherein, the exercise recommendation request is sent by the education provider server to the exercise recommendation server, and the exercise recommendation request is used to request the exercise recommendation server to send at least one recommended exercise question that meets the user's answering needs to the education provider server;

[0016] The recommended practice question receiving module is used to receive at least one recommended practice question sent by the education provider server and display it for the user to answer.

[0017] Fifthly, embodiments of this disclosure also provide an online learning device configured on an education provider server, the device comprising:

[0018] The exercise recommendation request receiving module is used to receive an exercise recommendation request sent by the client according to the user's answering needs, and send the exercise recommendation request to the exercise recommendation server; wherein, the exercise recommendation request is used to request the exercise recommendation server to provide at least one recommended exercise question that meets the user's answering needs;

[0019] The recommended practice question sending module is used to send at least one recommended practice question fed back by the practice question recommender server to the client, so that the client can display the at least one recommended practice question.

[0020] Sixthly, embodiments of this disclosure also provide an online learning device configured on a question recommendation server, the device comprising:

[0021] The exercise recommendation request receiving module is used to receive exercise recommendation requests sent by the education provider server; wherein, the exercise recommendation request is sent by the client to the education provider server according to the user's answer requirements;

[0022] The recommended practice question determination module is used to determine at least one recommended practice question that meets the user's answering needs based on the practice question recommendation request, and send it to the education provider server, so that the education provider server can send the at least one recommended practice question to the client and display the at least one recommended practice question through the client.

[0023] In a seventh aspect, embodiments of this disclosure also provide an electronic device, including a memory and a processor, wherein the memory stores a computer program, and when the computer program is executed by the processor, the processor executes any of the online learning methods provided in embodiments of this disclosure.

[0025] Compared with the prior art, the technical solution provided in this disclosure has at least the following advantages: In this disclosure, the client first sends a question recommendation request to the education provider server, then the education provider server sends the question recommendation request to the question recommender server, and sends the recommended practice questions fed back by the question recommender server to the client for the user to answer. The education provider server does not need to specifically maintain the question data related to question recommendation, and the client does not need to specifically preset the question recommendation function during the development stage (that is, the client's inherent function may not include the question recommendation function). As long as the client can successfully initiate a question recommendation request, the education provider server and the question recommender server can interact to send the recommended practice questions determined by the question recommender server to the client, thereby realizing the question recommendation function of the client. This solves the problem of high coupling between the question recommendation function and the education client in the existing solution, and the resulting high development cost of the education client. By utilizing the technical solution of this disclosure embodiment, the exercise recommendation function can be decoupled from the educational client, reducing the development cost of the educational client. Even if the educational client does not integrate the exercise recommendation function in advance during the development process, the technical solution of this disclosure embodiment can still provide recommended practice questions to users through the client to assist users in learning.

[0046] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0047] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0048] Figure 1 This diagram illustrates an interaction between a client, an education provider server, and a problem recommendation server, as provided in an embodiment of this disclosure, and serves as an example to illustrate the embodiments of this disclosure. Figure 1 As shown in the embodiments of this disclosure, the client mentioned is a client corresponding to the education provider server. That is, the client is provided by the education provider server. When a user uses the client for online learning, the client triggers a practice question recommendation request. The client sends the practice question recommendation request to the education provider server to request the education provider server to provide recommended practice questions. Since the education provider server does not need to specifically maintain practice question data related to practice question recommendations, it can send the practice question recommendation request to the practice question recommender server. The practice question recommender server determines the recommended practice questions and provides feedback to the education provider server. Then, the education provider server sends the recommended practice questions to the client for display.

[0049] The education provider server can be any server managed by any education service provider. The exercise recommendation server is a server managed by the exercise recommendation service provider that maintains exercise data related to exercise recommendations. Through the interaction between the education provider server and the exercise recommendation server, even if the education provider server itself does not maintain exercise data related to exercise recommendations, and the client does not specifically pre-configure exercise recommendation functionality during the development phase, as long as there is an entry point in the client that can trigger exercise recommendation requests, recommended practice questions can be successfully displayed in the client for users to answer.

[0050] Figure 2 This flowchart illustrates an online learning method provided by an embodiment of the present disclosure, applied to a client supporting online learning. This embodiment can be applied to situations involving the implementation of a client's exercise recommendation function. The online learning method provided by this embodiment can be executed by an online learning device configured in a client supporting online learning. This online learning device can be implemented in software and / or hardware and can be integrated into the client as a plugin. Furthermore, the plugin for implementing the online learning method provided by this embodiment can be integrated into any client supporting online learning on any operating system through a pre-set plugin interface. For example, it can be integrated into any client supporting online learning on the Android operating system through a plugin interface that matches the client on the Android operating system. Therefore, the online learning device or plugin provided by this embodiment has broad applicability. User terminals with the aforementioned client installed include, but are not limited to, mobile terminals, tablets, and laptops.

[0051] like Figure 2 As shown, the online learning method provided in this embodiment may include:

[0052] S101. Based on the user's question-answering needs, send a question recommendation request to the education provider server; wherein, the question recommendation request is sent by the education provider server to the question recommender server, and the question recommendation request is used to request the question recommender server to send at least one recommended practice question that meets the user's question-answering needs to the education provider server.

[0053] When users are using the client installed on their terminal for online learning, such as answering or viewing practice questions provided by the client, or learning knowledge points, if there is a need for recommended practice questions related to the current practice question or knowledge point, they can trigger the practice question recommendation request by touching the button or control on the current interface. The client will then send the practice question recommendation request to the education provider's server.

[0054] For example, based on the user's question-answering needs, a question recommendation request is sent to the education provider server, including: in response to the user's touch operation on the target control on the target interface, generating a question recommendation request and sending it to the education provider server; wherein, the target control is used by the user to trigger the question recommendation request, and the target interface may include any interface on the client with the target control, such as the client's original question answering interface, the client's original question viewing interface, the knowledge point learning interface, etc.

[0055] Figure 3 As an example, a schematic diagram of a target interface with target controls provided in an embodiment of this disclosure is shown, specifically using the original exercise viewing interface in the client as an example, and should not be construed as a specific limitation on the embodiments of this disclosure. Figure 3 As shown, the current exercise viewing interface displays a target control 31. This target control can be labeled with guiding phrases such as "Learn by analogy." Clicking this target control 31 triggers an exercise recommendation request. The specific location of the target control 31 on the current exercise viewing interface can be flexibly set according to the interface interaction requirements; this embodiment does not impose specific limitations. Furthermore, the specific content that can be displayed on the current exercise viewing interface, such as questions, answers, and explanations, can be flexibly adjusted according to needs. Other controls, such as print controls and add-to-error-note controls, can also be set according to requirements.

[0056] After receiving a question recommendation request from the client, the education provider server forwards the request to the question recommendation server according to the established communication method. The question recommendation server determines the target knowledge information corresponding to the original question based on the original question information carried in the request; alternatively, it uses the knowledge information carried in the request as the target knowledge information. Then, it identifies at least one practice question whose corresponding knowledge information is the same as or similar to the target knowledge information as at least one recommended practice question that meets the user's answering needs, and finally sends the identified at least one recommended practice question to the education provider server. The education provider server then sends the received at least one recommended practice question back to the client, which receives and displays it.

[0057] In this embodiment, the number of recommended practice questions determined by the practice question recommendation server is not specifically limited. For example, the number of recommended practice questions included in the practice question recommendation request can be defined during the development of the online learning plugin. For instance, the default number of recommended practice questions for each target knowledge information can be set to 3. Alternatively, a corresponding control can be set and displayed on the target interface for the number of recommended practice questions for each target knowledge information. When the user triggers the practice question recommendation request, the number of practice questions to be recommended for each target knowledge information can be determined based on the user's touch operation on the control related to the number of recommended practice questions. This result is then included in the practice question recommendation request and sent to the education provider server, allowing the practice question recommendation server to return the required number of recommended practice questions.

[0058] S102. Receive at least one recommended practice question sent by the education provider's server and display it for the user to answer.

[0059] When displaying recommended practice questions, the client can either switch from the current screen to a new screen to display at least one received recommended practice question, or display a pop-up window on the current screen to display at least one received recommended practice question.

[0060] In this embodiment, the client first sends a practice question recommendation request to the education provider server. The education provider server then forwards the request to the practice question recommender server and sends the recommended practice questions from the recommender server to the client for the user to answer. The education provider server does not need to maintain dedicated practice question data related to the recommendation, and the client does not need to pre-configure the practice question recommendation function during development. As long as the client can successfully initiate a practice question recommendation request, the education provider server and the practice question recommender server can interact, with the education provider server sending the recommended practice questions determined by the recommender server to the client. This achieves the client's practice question recommendation function, solving the problem of high coupling between the practice question recommendation function and the educational client in existing solutions, and the resulting high development costs for the educational client. In other words, the technical solution of this embodiment can decouple the practice question recommendation function from the educational client, reducing the development cost of the educational client. Even if the educational client does not pre-integrate the practice question recommendation function during development, the technical solution of this embodiment can still provide recommended practice questions to the user through the client to assist in learning.

[0061] Based on the above technical solution, the target control on the target interface used to trigger the exercise recommendation request includes a preset number of sub-controls, each sub-control corresponding to a different exercise recommendation strategy, and the exercise recommendation strategy includes the recommended exercise type;

[0062] Accordingly, in response to the user's touch operation on the target control on the target interface, a request for exercise recommendations is generated and sent to the education provider server, including:

[0063] In response to the user's touch operation on the target sub-control on the target interface, a request for exercise recommendations is generated and sent to the education provider server.

[0064] For example, the question types (or question formats) in the exercise recommendation strategy include, but are not limited to, multiple-choice questions, fill-in-the-blank questions, true / false questions, and open-ended questions. The corresponding exercise recommendation strategies include, but are not limited to: recommending multiple-choice and true / false questions first, then fill-in-the-blank questions; recommending multiple-choice and true / false questions first, then open-ended questions; recommending fill-in-the-blank questions first, then open-ended questions; recommending fill-in-the-blank questions first, then multiple-choice and true / false questions; or cross-recommending multiple-choice, fill-in-the-blank, and true / false questions. The exercise recommendation strategy may also include the number of recommended practice questions for each target knowledge information. Each exercise recommendation strategy corresponds to a sub-control. The client determines the exercise recommendation strategy based on the user's touch operation on the target sub-control (i.e., the sub-control selected by the user) and sends it to the education provider server in the exercise recommendation request. The exercise recommendation server ultimately determines the types and number of exercises to be recommended based on the exercise recommendation strategy in the received exercise recommendation request, and then sends at least one recommended practice question matching the exercise recommendation request to the client through the education provider server.

[0065] Optionally, receive and display at least one recommended practice question sent by the education provider's server, including:

[0066] Determine the sorting method for the exercises corresponding to the target sub-control;

[0067] Receive at least one recommended practice question from the education provider's server and display at least one recommended practice question in the order of the practice questions.

[0068] In this process, user interaction with the target sub-control not only determines the current question recommendation strategy for the client but also the display order of the received recommended practice questions. The question order corresponds to the recommendation strategy. For example, if the target sub-control's recommendation strategy is to recommend multiple-choice and true / false questions first, followed by fill-in-the-blank questions, then the client will display at least one recommended practice question in the following order: multiple-choice and true / false questions first, followed by fill-in-the-blank questions. By determining the recommendation strategy and question order based on the target sub-control, the client ensures that the display of recommended practice questions meets the user's answering needs, achieving a personalized display effect.

[0069] Optionally, receive and display at least one recommended practice question sent by the education provider's server, including:

[0070] The system receives at least one recommended practice question from the education provider server, and also receives a practice question interactive rendering request from the education provider server. That is, after receiving the recommended practice question from the practice question recommender server, the education provider server generates a corresponding practice question interactive rendering request and sends it to the client to request the client to render the received recommended practice question.

[0071] Based on the exercise interaction rendering request, the exercise interaction rendering module is invoked to render at least one recommended exercise question and display the rendered at least one recommended exercise question; wherein, the exercise interaction rendering module predefines the rendering method of the recommended exercise questions and can be implemented by software and / or hardware.

[0072] The rendering method for recommended practice questions can be determined based on the display style of the question stem and the user-supported answering method. For example, for fill-in-the-blank questions, the part of the question stem requiring user answers can be displayed using parentheses or underlines. Users can answer by calling a custom keyboard pre-set for the client. This custom keyboard refers to the interface keyboard that matches the question recommendation function and is invoked for answering recommended practice questions. Since the question recommendation function is decoupled from the client's inherent functions, to ensure that answering recommended practice questions can be implemented in any educational client, the custom keyboard matching the question recommendation function can be preferentially used when users answer recommended practice questions. For multiple-choice questions, after displaying the question stem and each option, users can select the answer by clicking, long-pressing, or other touch operations.

[0073] By calling the exercise interaction rendering module to render the recommended exercises, the recommended exercises can be rendered without relying on the client's inherent functions. This also helps the exercise recommendation function in this embodiment to be integrated into any educational client in the form of a plug-in.

[0074] Figure 4 This diagram illustrates a problem-solving interface provided in an embodiment of this disclosure, specifically using fill-in-the-blank questions as an example. It serves as an illustrative description of the problem-solving interface in this embodiment and should not be construed as a specific limitation of the embodiments of this disclosure. Figure 4As shown, after being rendered and displayed, the recommended practice questions are presented to the user for answering. The user can then click on the blank area corresponding to the underlined part of the question to trigger the invocation of a pre-set custom keyboard and input their answers using it. The form of the custom keyboard can be flexibly set according to needs, and this embodiment does not impose specific limitations. Furthermore, the exercise display interface may also include other display controls, such as control 41 for triggering answer confirmation or submission operations. Control 41 may also display text such as "Filled in" to guide the user to confirm or submit their answers. Further, the upper right corner of the exercise display interface may also display the question number of the current recommended practice question and the answering progress of the current recommended practice question, for example... Figure 4 The "2 / 5" displayed in the upper right corner indicates that the client has received 5 recommended practice questions, and the current screen shows the 2nd practice question. The circle can be filled with a preset color to indicate the current answering progress; when the circle is completely filled, it means the current question has been answered. Furthermore, Figure 4 Although the exercise display interface shown only displays one recommended exercise question, in actual application, the exercise display interface can display at least two recommended exercise questions at the same time. This embodiment of the disclosure does not make specific limitations in this regard.

[0075] Figure 5 The flowchart illustrates another online learning method provided in this embodiment of the present disclosure. It is based on the above technical solution and is further optimized and extended, and can be combined with the above optional implementation methods.

[0076] like Figure 5 As shown, the online learning method provided in this embodiment may include:

[0077] S201. Based on the user's question-answering needs, send a question recommendation request to the education provider server; wherein, the question recommendation request is sent by the education provider server to the question recommender server, and the question recommendation request is used to request the question recommender server to send at least one recommended practice question that meets the user's question-answering needs to the education provider server.

[0078] S202. Receive at least one recommended practice question sent by the education provider's server and display it for the user to answer.

[0079] S203, In response to the user's answer submission operation on the exercise display interface, determine the target recommended exercise question that the user answered and determine the user's input answer that corresponds to the target recommended exercise question.

[0080] For example, after a user completes the answer input, they can trigger the answer submission operation by touching a control on the exercise display interface, such as... Figure 4The control 41 on the exercise display interface is used to submit answers, so that the client can determine the target recommended exercise questions and the corresponding user answers.

[0081] Optionally, before determining the target recommended practice question and the user's input answer corresponding to the target recommended practice question in response to the user's answer submission operation on the exercise display interface, the method provided in this disclosure embodiment further includes:

[0082] In response to the user's input of answers to the recommended practice questions on the exercise display interface, the answer submission control on the exercise display interface is switched from a non-touchable state to a touchable state; the answer submission control is used by the user to trigger the answer submission operation.

[0083] By controlling the touch-sensitive state of the answer submission control based on the user's answer input, we can improve the user-friendliness of the interface and prevent accidental triggering of the answer submission operation when the user has not entered any answers.

[0084] Figure 6 This diagram illustrates the state switching of an answer submission control on a question display interface, as provided in this embodiment of the disclosure. It is intended to provide an illustrative example of the embodiments of this disclosure and should not be construed as a specific limitation of the embodiments of this disclosure. Specifically, Figure 6 Let's take the display of multiple-choice questions on the exercise display interface as an example for illustration. For example... Figure 6 As shown in the left image, the answer submission control 61 is in a non-touchable state when the user has not entered an answer (i.e., the user has not selected an option). Once the user enters an answer, for example, by selecting option A, the answer submission control 61 becomes touchable, supporting actions such as clicking and long-pressing. The user submits the answer using the touch control 61. For the user-selected option, the client can use methods such as adding a highlighting image or filling the option area to differentiate the selected option from other options.

[0085] S204. Based on the target recommended practice questions and user answers, send an answer correction request to the education provider server; wherein, the answer correction request is sent by the education provider server to the practice question recommender server, and the answer correction request is used to request the practice question recommender server to determine whether the user's answer is correct, and send the determination result to the education provider server.

[0086] The process involves the exercise recommendation server determining the standard answer to a recommended exercise based on the information in the answer grading request. This standard answer is then compared to the user's answer in the grading request to determine its correctness. If the user's answer matches the standard answer, the server confirms it is correct and sends it to the education provider server, which then forwards the result to the client for display. Conversely, if the user's answer does not match the standard answer, the server confirms it is incorrect and sends this result to the education provider server, which in turn forwards the result to the client for display.

[0087] S205. Receive the confirmation result sent by the education provider's server regarding whether the user's answer is correct, and display it on the exercise display interface.

[0088] In other words, through the interaction between the client, the education provider server, and the exercise recommendation server based on answer grading requests, online grading of recommended exercises and visualization of grading results are achieved. Even if the client's inherent functions do not support exercise recommendation and grading functions, the technical solution of this disclosure can supplement the client's functions and still meet the user's needs for exercise recommendation and online grading.

[0089] Optionally, receive the determination result regarding the correctness of the user's answers sent by the education provider's server, and display it on the exercise display interface, including:

[0090] Receive the confirmation result from the education provider's server regarding whether the user's answer is correct;

[0091] Get the dynamic icon corresponding to the result; wherein, the specific implementation style of the dynamic icon can be flexibly set according to the requirements. On the basis of ensuring that the display of the dynamic icon can improve the interface display effect, the specific implementation style of the dynamic icon is not specifically limited in this embodiment.

[0092] The sub-area corresponding to the user's answer on the exercise display interface is determined, and the dynamic icon is displayed on the sub-area. The size of the sub-area corresponding to the user's answer can also be preset by the developers. This embodiment does not impose a specific limitation. The dynamic icon and the user's answer can be displayed superimposed. At this time, the dynamic icon can also be set with a certain transparency to avoid covering the display of the user's answer.

[0093] Furthermore, if it is determined that the user's answer is incorrect, the method provided in this disclosure embodiment further includes:

[0094] In response to the user's action of adding incorrect questions on the exercise display interface, the recommended practice questions are added to the incorrect question collection.

[0095] Figure 7 This is a schematic diagram illustrating an interface for displaying grading results of exercises, provided as an embodiment of this disclosure. Figure 7 Taking multiple-choice questions as an example, the left image shows the grading result when the user answers correctly, and the right image shows the grading result when the user answers incorrectly. The "checkmark" icon for correct answers and the "wrong" icon for incorrect answers can be implemented using dynamic icon styles, meaning they will display dynamically during the display. Furthermore, for users who answer incorrectly, the exercise display interface can also show controls for adding incorrect questions, such as... Figure 7 The interface displays a control labeled "Add to Error Notebook," which users can touch to add the currently incorrect question to their error collection. If the user is not currently answering the last question, the interface can also display a question-switching control for moving to the next question, for example... Figure 7 The interface displays a control that says "Next Question"; if the user is currently answering the last question, the exercise display screen can also display a control to trigger the completion of the exercise. Figure 7 (Not shown in the image).

[0096] Figure 8 This is a schematic diagram illustrating another interface for displaying grading results of exercises, provided as an embodiment of this disclosure. Figure 8 Taking fill-in-the-blank questions as an example, the grading results for correct and incorrect answers are displayed respectively.

[0097] Optionally, based on the above technical solution, in the process of receiving the determination result of whether the user's answer is correct sent by the education provider's server and displaying it on the exercise display interface, the method provided in this embodiment of the disclosure further includes:

[0098] A request to retrieve the parsing information of the target recommended practice questions is sent to the education provider server. The parsing information retrieval request is sent by the education provider server to the practice question recommender server. The parsing information retrieval request is used to request the practice question recommender server to send the parsing information of the target recommended practice questions to the education provider server. During the process of maintaining the recommended practice question data, the practice question recommender server can maintain the correct answer and answer parsing information of each practice question at the same time.

[0099] Receive the analysis information of the target recommended practice questions sent by the education provider's server, and display the analysis information on the practice question display interface.

[0100] like Figure 7 or Figure 8 As shown, the exercise display interface can show the grading results and explanation information at the same time, thus helping users to answer their questions.

[0101] If the recommended practice questions do not have corresponding explanation information, the practice question recommender server can return a notification message that no explanation information exists to the education provider server. Correspondingly, the client will display a message indicating that no explanation information exists in the display sub-area corresponding to the explanation information.

[0102] Optionally, the method provided in this embodiment further includes: during the user's answering process, if a user's request to exit the practice is detected, the user's answering progress information on the exercise display interface is recorded; wherein, the answering progress information restores the user's answering progress on the exercise display interface.

[0103] Figure 9 This is a schematic diagram of an interface for confirming whether a user has exited a practice session, provided as an embodiment of this disclosure. Figure 9 As shown, users can trigger an exit request by touching the exit control in the upper left corner of the exercise display interface. Based on the user's exit request, the client can pop up a prompt window or dialog box to confirm whether the user wants to exit. If the user clicks to confirm exit, the exercise display interface will end. At the same time, the client records the user's answering progress information on the exercise display interface.

[0104] Figure 10 This is a schematic diagram of an interface for recording exercises, provided in an embodiment of this disclosure. When a user exits or completes the current exercise, the client interface can be switched to the exercise recording interface, such as... Figure 10 As shown, this interface displays a print control. Touching this control triggers the printing of the recorded exercises. The exercises to be printed can be all exercises or a subset selected based on the user's action. Furthermore, the exercise recording interface also allows users to view only the incorrect answers. For example, by touching the incorrect answer filter control, the user can trigger a filter operation, and the client will only display the user's incorrect answers based on this filter. Moreover, the exercise recording interface can be automatically displayed after the user confirms and exits the exercise session. Figure 9 The displayed interface switches to Figure 10 The interface shown.

[0105] It should be noted that the embodiments of this disclosure do not impose specific limitations on the display position of controls on any interface of the client, and can be flexibly set according to the interface layout. For example Figure 10 The print control on the interface shown can be displayed in the upper right corner of the interface or at the bottom of the interface.

[0106] Figure 11 A flowchart illustrating another online learning method provided in this disclosure is used to exemplarily illustrate embodiments of this disclosure. Figure 11As shown, the exercise recommendation server, education provider server, and client transmit data through pre-set communication interfaces. The type and number of communication interfaces can be adaptively configured according to the different types of data transmitted; this embodiment does not impose specific limitations. Furthermore, the grading module can be integrated into the exercise recommendation server as a plug-in, with both transmitting data through a pre-set plug-in interface; similarly, the online answering module can be integrated into the client as a plug-in, with both transmitting data through a pre-set plug-in interface.

[0107] like Figure 11 As shown, the exercise recommendation server can pre-create an online exercise question pool to maintain the data for recommended exercise questions, and then launch the online exercise question bank to provide exercise recommendation and online grading services. The exercise recommendation server receives exercise recommendation requests (or incorrect question recommendation requests) sent by the education provider server, determines the target knowledge information corresponding to the original question based on the original question information carried in the exercise recommendation request, or uses the knowledge information carried in the exercise recommendation request as the target knowledge information; then, according to the question recommendation logic, it determines at least one exercise question whose corresponding knowledge information is the same as or similar to the target knowledge information as at least one to be recommended. The system recommends practice questions and filters out previously recommended questions to determine if the remaining number of questions meets the required number of recommendations. If it does, the remaining recommended practice questions are sorted (e.g., by the type of recommended questions carried in the recommendation request) and sent to the client for display via the education provider's server. If it does not meet the requirement, a certain number of recommended practice questions need to be retrieved from the question bank based on the determined target knowledge information and the question types of the recommended practice questions. Once the required number of recommendations is met, the system sends the questions back to the education provider's server. In this second retrieval, previously recommended questions also need to be filtered out. For example, the recommended practice question information sent by the practice question recommender server to the education provider server can be divided into three modules: The content of the first module may include, but is not limited to: the determined similar question ID, the knowledge point similarity score or the question similarity score, the main basic knowledge points of the similar questions, the input question type and book type, etc. The content of the second module may include, but is not limited to: the determined similar question ID, the question stem content and the question answer (i.e., the standard answer), etc. The content of the third module may include, but is not limited to: the original question ID list in the practice question recommendation request, the expected number of questions to be returned and the user ID, etc.

[0108] After receiving recommended practice questions from the question recommending server, the education provider server sends a question interaction rendering request to the client. Based on this request, the client invokes the question interaction rendering module (or online question answering module) to render at least one of the received recommended practice questions and displays the rendered question (showing it as answerable by the user). The user can input answers using a pre-set custom keyboard that matches the question recommendation function. After inputting the answers, the client can send a user-triggered answer correction request to the education provider server to request online correction of the user's answers. The education provider server then sends the correction request to the question recommending server, which invokes the correction module to determine if the user's answer is correct and sends the correction result back to the client for display.

[0109] Figure 12 The flowchart illustrates another online learning method provided in this disclosure, specifically using the example of recommending exercises based on original questions displayed in the client. This is an illustrative description of the embodiments of this disclosure and should not be construed as a specific limitation on the embodiments of this disclosure.

[0110] like Figure 12 As shown, after a user triggers a practice question recommendation request in the client, the request is sent from the education provider server to the practice question recommender server. The practice question recommender server determines the total number of practice questions to be recommended, n, where n is the product of the number of recommendations m (where m can be flexibly set, e.g., m=3) for each incorrect question and the number of incorrect questions. Based on the question type and original question information carried in the recommendation request, the server formulates the recommendation logic and then determines the practice questions to be recommended. If the number of recommended practice questions determined from the first practice question bank is insufficient to meet the total number of recommendations, the second practice question bank is used to supplement the questions to meet the total number of recommendations. The first and second practice question banks can be obtained by classifying practice questions according to their relevance to specific knowledge points. For example, the first practice question bank refers to a set of practice questions with high relevance to specific knowledge points, and the second practice question bank refers to a set of practice questions with low relevance to specific knowledge points. Of course, provided that the recommended practice questions are successfully determined, the first and second practice question banks can also be established and maintained in other ways. Through the interaction between the exercise recommendation server, the education provider server, and the client, the recommended practice questions determined by the exercise recommendation server are displayed on the client.

[0111] The client can sequentially display the received recommended practice questions for the user to answer. If the client detects a user's request to exit the practice, it determines whether the user has truly exited the current practice. If exiting, the current practice ends, and upon detecting a request from the user to resume practice, the client continues displaying recommended practice questions. If the user has not exited, the client retrieves the user's input answer based on the user's answering method corresponding to the question type of the recommended practice questions. Furthermore, based on the user's answer submission, the client sends an answer correction request to the education provider server. Through interaction between the education provider server and the practice question recommending server, the client receives the answer correction result and displays it on the front end. For incorrect answers, the client can also add them to a mistake notebook for easy review later. This process is repeated until the current practice is completed.

[0112] Figure 13 The flowchart illustrates another online learning method provided in this disclosure, applied to an education provider server. This disclosure can be applied to situations involving how to implement a client-side exercise recommendation function. The online learning method applied to an education provider server provided in this disclosure can be executed by an online learning device configured on the education provider server, which can be implemented using software and / or hardware.

[0113] The online learning method applied to the education provider server provided in this disclosure is executed in conjunction with the online learning method applied to the client supporting online learning and the online learning method applied to the exercise recommendation server. For content not described in detail in the following embodiments, please refer to the explanations in the above embodiments.

[0114] like Figure 13 As shown, the online learning method provided in this embodiment may include:

[0115] S501. Receive a question recommendation request sent by the client based on the user's question-answering needs, and send the question recommendation request to the question recommendation server; wherein, the question recommendation request is used to request the question recommendation server to provide at least one recommended practice question that meets the user's question-answering needs.

[0116] S502. Send at least one recommended practice question from the practice question recommender server to the client so that the client can display at least one recommended practice question.

[0117] Optionally, in the process of sending at least one recommended practice question from the practice question recommendation server to the client, the method provided in this disclosure embodiment further includes:

[0118] Generate an interactive exercise rendering request and send it to the client. The interactive exercise rendering request is used to request the client to call the interactive exercise rendering module to render at least one recommended exercise question and display the rendered at least one recommended exercise question. The interactive exercise rendering module predefines the rendering method of the recommended exercise questions.

[0119] Optionally, after sending at least one recommended practice question from the practice question recommendation server to the client, the method provided in this disclosure embodiment further includes:

[0120] Receive answer grading requests sent by the client; wherein, the answer grading requests are sent by the client based on the target recommended practice questions answered by the user and the user's answers corresponding to the target recommended practice questions, and the target recommended practice questions and user answers are determined by the client based on the user's answer submission operation on the exercise display interface;

[0121] The answer grading request is sent to the exercise recommender server; the answer grading request is used to ask the exercise recommender server to determine whether the user's answer is correct and to provide feedback on the result.

[0122] The system sends the confirmation result regarding the correctness of the user's answer, which is returned by the question recommendation server, to the client so that the client can display the confirmation result on the question display interface.

[0123] Optionally, in the process of sending the determination result regarding whether the user's answer is correct, fed back by the exercise recommendation server, to the client, the method provided in this disclosure embodiment further includes:

[0124] Receive a request from the client to retrieve the parsing information for the target recommended practice questions;

[0125] The parsing information retrieval request is sent to the exercise recommendation server; the parsing information retrieval request is used to request the exercise recommendation server to provide the parsing information of the target recommended exercise questions;

[0126] The solution information of the target recommended practice questions fed back by the practice question recommendation server is sent to the client so that the client can display the solution information on the practice question display interface.

[0127] In this embodiment, the client first sends a practice question recommendation request to the education provider server. The education provider server then forwards the request to the practice question recommender server and sends the recommended practice questions from the recommender server to the client for the user to answer. The education provider server does not need to maintain dedicated practice question data related to the recommendation, and the client does not need to pre-configure the practice question recommendation function during development. As long as the client can successfully initiate a practice question recommendation request, the education provider server and the practice question recommender server can interact, with the education provider server sending the recommended practice questions determined by the recommender server to the client. This achieves the client's practice question recommendation function, solving the problem of high coupling between the practice question recommendation function and the educational client in existing solutions, and the resulting high development costs for the educational client. In other words, the technical solution of this embodiment can decouple the practice question recommendation function from the educational client, reducing the development cost of the educational client. Even if the educational client does not pre-integrate the practice question recommendation function during development, the technical solution of this embodiment can still provide recommended practice questions to the user through the client to assist in learning. Furthermore, by adopting the technical solution of this disclosure embodiment, the client also supports the online grading function of recommended exercises, thereby expanding the functionality of the client and improving the user experience.

[0128] Figure 14 The flowchart illustrates another online learning method provided in this disclosure, applied to a problem-recommendation server. This disclosure can be applied to various scenarios involving the implementation of problem recommendation functionality on a client side. The online learning method applied to a problem-recommendation server provided in this disclosure can be executed by an online learning device configured on the problem-recommendation server, which can be implemented using software and / or hardware.

[0129] The online learning method applied to the exercise recommendation server provided in this disclosure is executed in conjunction with the online learning method applied to the client supporting online learning and the online learning method applied to the education provider server. For content not described in detail in the following embodiments, please refer to the explanations in the above embodiments.

[0130] like Figure 14 As shown, the online learning method provided in this embodiment may include:

[0131] S601, Receive a question recommendation request sent by the education provider server; wherein, the question recommendation request is sent by the client to the education provider server based on the user's question answering needs.

[0132] S602. Based on the exercise recommendation request, determine at least one recommended exercise question that meets the user's answering needs, and send it to the education provider server, so that the education provider server can send at least one recommended exercise question to the client and display at least one recommended exercise question through the client.

[0133] Optionally, based on the exercise recommendation request, at least one recommended practice question that meets the user's answering needs is determined, including:

[0134] Based on the original question information carried in the question recommendation request, determine the target knowledge information corresponding to the original question; or, use the knowledge information carried in the question recommendation request as the target knowledge information.

[0135] At least one practice question whose corresponding knowledge information is the same as or similar to the target knowledge information is identified as at least one recommended practice question that meets the user's question-answering needs.

[0136] Optionally, the exercise recommendation request may also include an exercise recommendation strategy, which may include the types of exercises to be recommended.

[0137] Accordingly, at least one practice question whose corresponding knowledge information is the same as or similar to the target knowledge information is identified as at least one recommended practice question that meets the user's answering needs, including:

[0138] At least one practice question that has the same or similar knowledge information as the target knowledge information and meets the question type requirements in the question recommendation strategy is identified as at least one recommended practice question that meets the user's question-answering needs.

[0139] The exercise recommendation strategy includes, but is not limited to, multiple-choice, fill-in-the-blank, true / false, and open-ended questions. The strategy may also include the number of recommended practice questions for each target knowledge point. On the client side, the target control on the interface that triggers the exercise recommendation request includes a preset number of sub-controls. Each sub-control corresponds to a different exercise recommendation strategy. Users can select and interact with sub-controls based on their answering needs. The resulting exercise recommendation request will carry information such as the type and number of recommended exercises, allowing the exercise recommendation server to accurately determine which practice questions meet the user's answering requirements.

[0140] Optionally, at least one practice question whose corresponding knowledge information is the same as or similar to the target knowledge information is identified as at least one recommended practice question that meets the user's answering needs, including:

[0141] Determine whether there are any previously recommended historical practice questions among at least one practice question whose corresponding knowledge information is the same as or similar to the target knowledge information.

[0142] If such a question exists, remove the historical questions from at least one practice question whose corresponding knowledge information is the same as or similar to the target knowledge information, and determine the remaining practice questions as at least one recommended practice question that meets the user's answering needs.

[0143] Here, "historically recommended practice questions" refers to practice questions that have already been displayed in the client during the recommendation process most closely related to the current one. For example, by comparing practice question IDs (used to uniquely identify practice questions) or calculating question similarity, it can be determined whether a previously recommended practice question exists among at least one practice question whose corresponding knowledge information is identical or similar to the target knowledge information. Filtering out this historical practice question can prevent duplicate recommendations of the same practice question.

[0144] Optionally, after determining at least one recommended practice question that meets the user's answering needs based on the practice question recommendation request and sending it to the education provider's server, the method provided in this disclosure embodiment further includes:

[0145] Receive answer grading requests sent by the education provider server; wherein, the answer grading request is sent by the client to the education provider server based on the target recommended practice questions answered by the user and the user's answers corresponding to the target recommended practice questions, and the target recommended practice questions and user answers are determined by the client based on the user's answer submission operation on the exercise display interface;

[0146] The system determines whether the user's answer is correct based on the answer correction request and sends the result to the education provider's server. The education provider's server then sends the result to the client, and the client displays the result on the exercise display interface.

[0147] Optionally, after determining whether the user's answer is correct based on the answer correction request and sending the determination result to the education provider's server, the method provided in this disclosure embodiment further includes:

[0148] Receive a request from the education provider server to obtain the parsing information of the target recommended practice questions; wherein, the parsing information retrieval request is sent by the client to the education provider server;

[0149] Based on the request for parsing information, the parsing information of the target recommended practice questions is determined and sent to the education provider's server, so that the education provider's server can send the parsing information to the client and display the parsing information on the practice question display interface through the client.

[0150] In this embodiment, the client first sends a practice question recommendation request to the education provider server. The education provider server then forwards the request to the practice question recommender server and sends the recommended practice questions from the recommender server to the client for the user to answer. The education provider server does not need to maintain dedicated practice question data related to the recommendation, and the client does not need to pre-configure the practice question recommendation function during development. As long as the client can successfully initiate a practice question recommendation request, the education provider server and the practice question recommender server can interact, with the education provider server sending the recommended practice questions determined by the recommender server to the client. This achieves the client's practice question recommendation function, solving the problem of high coupling between the practice question recommendation function and the educational client in existing solutions, and the resulting high development costs for the educational client. In other words, the technical solution of this embodiment can decouple the practice question recommendation function from the educational client, reducing the development cost of the educational client. Even if the educational client does not pre-integrate the practice question recommendation function during development, the technical solution of this embodiment can still provide recommended practice questions to the user through the client to assist in learning. Furthermore, by adopting the technical solution of this disclosure embodiment, the client also supports the online grading function of recommended exercises, thereby expanding the functionality of the client and improving the user experience.
