Description

Technical Field

[0001] This invention relates to the field of AI teaching and intelligent management technology, and more specifically, to a teaching control method, device, system, equipment, and storage medium. Background Technology

[0002] With the rapid development of information technology and the widespread use of smart devices, mobile phones, tablets, and other electronic products have become indispensable tools in students' daily lives. However, while these devices bring convenience, they also have a significant negative impact on students' learning habits, concentration, and physical and mental health. Numerous studies have shown that excessive or inappropriate use of smartphones and tablets by students can easily lead to addiction to entertainment applications (such as games, short videos, and social media), distraction from learning, and reduced effective study time, thereby affecting academic performance and the development of self-learning abilities. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a teaching management method, apparatus, equipment, teaching management system, and computer-readable storage medium.

[0004] To achieve the above objectives, the technical solutions adopted in the embodiments of the present invention are as follows: In a first aspect, the present invention provides a teaching management and control method applied to a teaching management and control device within a teaching management and control system. The teaching management and control system further includes a backend server and an electronic workbook. The teaching management and control device is communicatively connected to both the backend server and the electronic workbook. A learning application is deployed on the teaching management and control device. The method includes: The system receives learning tasks for the current task cycle from the backend server. These learning tasks include homework assigned by teachers, extracurricular homework assigned by parents, and learning or practice content generated by the backend server based on the student's historical learning data in the electronic workbook and the teaching control device, which analyzes the student's mastery of knowledge points. When the system detects that a student user attempts to use the teaching control device during the current task period, it enters a preset interface and determines whether the learning task has been completed. If the learning task is not completed, access to functions on the teaching management device that do not belong to the learning application will be restricted during the current task cycle, and a list of learning tasks to be completed and a progress bar will be displayed on the lock screen and main screen of the teaching management device.

[0005] Optionally, the method further includes: If the student user submits task completion data within the current task period, the task completion data is sent to the backend server so that the backend server can determine whether the learning task is completed based on the task completion data; wherein, the task completion data includes the student's answer content and its original handwriting information collected through the electronic workbook and the teaching control device, as well as the audio, images or videos of the answer content collected through the electronic workbook and the teaching control device; Upon receiving a message from the backend server indicating that the task has been completed, access restrictions on functions of the teaching management device that are not part of the learning application are lifted, allowing the student user to use all functions of the teaching management device.

[0006] Optionally, the method further includes: If the backend server returns a message indicating that the task is not completed, the unfinished portion of the learning task will be postponed to the next task cycle. In the next task cycle, access to functions on the teaching management device that do not belong to the learning application will be continuously restricted until the learning task is fully completed.

[0007] Optionally, the method further includes: If the student user fails to submit the task completion data within the current task cycle, the learning task will be postponed to the next task cycle, and access to functions on the teaching management device that do not belong to the learning application will be continuously restricted in the next task cycle until the learning task is fully completed.

[0008] Optionally, the method further includes: If the teaching control device is a student device, a task status notification message and synchronization information are sent to the parent device in the teaching control system so that the parent user can know the execution process and completion status of the learning task, as well as the usage of functions on the teaching control device that are not part of the learning application.

[0009] Optionally, before lifting the access restrictions on functions of the teaching control device that do not belong to the learning application, the method further includes: If the teaching control device is a student device and receives a control release command sent by a parent device in the teaching control system, then the access restrictions on functions on the teaching control device that do not belong to the learning application are released. If the teaching control device receives a continuous control instruction from a parent's device in the teaching control system, then the access restriction on functions on the teaching control device that do not belong to the learning application will remain in effect.

[0010] Secondly, the present invention provides a teaching management and control device, applied to a teaching management and control system, wherein the teaching management and control system further includes a backend server and an electronic workbook, the teaching management and control device being communicatively connected to both the backend server and the electronic workbook, and a learning application being deployed on the teaching management and control device; the device includes: The receiving module is used to receive learning tasks for the current task cycle issued by the backend server. The learning tasks include homework assigned by teachers, homework assigned by parents, and learning content or practice content generated by the backend server after analyzing the student's mastery of knowledge points based on the student's historical learning data on the electronic workbook and the teaching control device. The processing module is used to enter a preset interface when it detects that the student user attempts to use the teaching management device during the current task period, and to determine whether the learning task has been completed; if the learning task has not been completed, it restricts access to functions on the teaching management device that do not belong to the learning application during the current task period, and displays a list of learning tasks to be completed and a progress bar on the lock screen and main interface of the teaching management device.

[0011] Thirdly, the present invention provides a teaching control device, including a processor, a memory, a display, and an input / output terminal. The memory stores machine-executable instructions that can be executed by the processor, and the processor can execute the machine-executable instructions to implement the teaching control method described in the first aspect above.

[0012] Fourthly, the present invention provides a teaching management and control system, which includes a backend server, parent devices, electronic workbooks, and teaching management and control equipment as described in the third aspect above.

[0013] Fifthly, the present invention provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the teaching control method as described in the first aspect above.

[0014] The teaching management and control method, device, system, equipment, and storage medium provided in this invention embodiment are as follows: The teaching management and control device receives learning tasks for the current task period issued by the backend server. These learning tasks include homework assigned by teachers, extracurricular homework assigned by parents, and learning content or practice content generated by the backend server based on the student's historical learning data on their electronic workbook and the teaching management and control device, analyzing the student's mastery of knowledge points. When the system detects that a student is attempting to use the teaching management and control device within the current task period, it enters a preset interface and determines whether the learning task has been completed. If the learning task is not completed, access to functions on the teaching management and control device that are not part of the learning application is restricted within the current task period, and a list of pending learning tasks and a progress bar are displayed on the lock screen and main interface of the teaching management and control device. Because this invention embodiment dynamically binds the usage permissions of functions on the teaching management and control device that are not part of the learning application with the completion status of learning tasks, it achieves intelligent and closed-loop management of learning control. On the one hand, by combining the completion status of homework assigned by teachers and parents with personalized learning and practice content generated based on historical learning data, the relevance and scientific nature of learning tasks are enhanced. On the other hand, when students attempt to access entertainment and other functions, a task verification mechanism is triggered. If the task is not completed, usage is restricted and a list of tasks to be done and their progress are displayed in real time, effectively preventing distraction and strengthening behavioral constraints. At the same time, a visual progress bar enhances positive incentives, prompting students to prioritize completing learning tasks, thereby cultivating good learning habits, improving self-learning efficiency and ability, and achieving refined teaching management with the collaborative participation of parents, teachers, and the system.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0022] With the widespread adoption of mobile internet and smart devices, smartphones and tablets have become indispensable tools in students' daily lives. However, their powerful entertainment functions have also led to serious attention deficit problems. Many students become addicted to non-academic applications such as games, short videos, and social networks, resulting in a series of negative impacts, including decreased learning efficiency, vision damage, and disrupted sleep patterns. Although parents and teachers are generally aware of the seriousness of this problem, there is currently a lack of effective means to scientifically guide and enforce regulations on students' use of electronic devices.

[0023] Several management solutions for students' use of electronic devices have emerged in the existing technology, mainly including the following categories: 1. Basic Time Control Software: Some smartphones or tablets have built-in "Screen Time," "Kids Mode," or third-party "Anti-Addiction Apps" that restrict students' access to specific apps by setting daily usage limits, app blacklists, and usage time periods. While these solutions can reduce ineffective usage time to some extent, their management mechanisms are relatively crude, fail to link with learning behaviors, and are easily bypassed by older students through methods such as resetting the device or switching accounts, resulting in limited actual control effectiveness.

[0024] 2. Dedicated learning devices (such as learning machines): There are dedicated hardware products on the market designed for educational purposes. These typically employ a closed system design, pre-installing only teaching resources and practice question banks, and prohibiting the installation of entertainment applications. While these devices avoid sources of interference, they often fail to motivate students to use them actively due to issues such as limited content, outdated updates, and poor interactive experience. They often become "dispensable" auxiliary tools or are even abandoned.

[0025] 3. E-textbooks and e-notebooks: Some manufacturers have launched e-paper devices or e-ink tablets with functions such as handwriting input, annotation reading, and homework recording, supporting students in completing some digital learning tasks. However, these devices mainly focus on information presentation and recording functions, lacking deep integration with the classroom teaching system. They fail to achieve advanced functions such as assigning and simultaneously handwriting homework, automatic homework grading, intelligent collection of wrong answers, personalized learning content and path recommendations, and cannot form a unified management loop with other home devices.

[0026] 4. Error Scanning and Printing Equipment: This error sorting tool, based on image recognition technology, can scan test papers by taking photos and generate a collection of errors for later review. Although it has a certain level of intelligence in data collection, its function is limited to post-processing. It cannot comprehensively analyze and judge historical errors for each subject, does not intervene in the learning process, and cannot apply positive incentives or negative constraints to students' learning behavior.

[0027] In summary, the following common defects are prevalent in various products currently available: 1. Functional isolation: There is a lack of linkage between subsystems or individual devices, and the completion status of learning tasks is not linked to device usage permissions; 2. Passive learning: The learning content is fixed, and the difficulty, type, and quantity of tasks cannot be dynamically adjusted according to the students' actual mastery. 3. Ineffective control: Existing control measures rely heavily on external rules and lack an internal driving mechanism, which can easily lead to resistance from students. 4. Data fragmentation: Learning behavior data is collected incompletely and not in real time, making it impossible to integrate and analyze data across subjects, which makes it difficult to support accurate learning analysis and personalized teaching decisions.

[0028] 5. Failure to identify and resolve problems in a timely manner: Failure to identify learning problems accurately and promptly; lack of timely and effective remedial measures for existing problems or unmastered knowledge points; and inability to provide students with assistance and guidance services throughout the entire learning process and cycle.

[0029] In this regard, embodiments of the present invention provide a teaching management and control method, device, system, equipment, and storage medium, which will be described in detail below.

[0030] Please refer to Figure 1 This is a block diagram of a teaching management and control system, which includes teaching management and control equipment. This equipment is for student use. Figure 1 The equipment includes 100 student devices; it can also be used by parents. Figure 1 Parental devices in the 200.

[0031] The teaching management and control system also includes a back-end server 300, electronic workbooks 400, and teacher-end devices 500.

[0032] Student Device 100 is a smart terminal used by students daily, including smartphones, tablets, or other mobile computing devices with internet access. A teaching management APP (i.e., a learning application) is installed on Student Device 100. After installation, the APP is automatically set as a startup item, and usage restriction policies are set at the system level. Before completing the designated learning task, the operating system of Student Device 100 is locked to the learning task prompt and task execution interface, allowing access only to learning-related functional modules (such as viewing task content, completing assignments, watching instructional videos, and reviewing incorrect answer explanations), and prohibiting access to entertainment applications, social media platforms, games, browsers, and other unauthorized functions.

[0033] Parental device 200 is a smart terminal device owned by a family member, such as a parent's mobile phone or tablet, which also has the aforementioned teaching management APP installed. As a crucial control terminal of the teaching management system, parental device 200 receives student learning progress notifications, views learning reports, assists students in completing assignments, sets personalized management rules (such as maximum daily usage time, available time periods, and exception whitelist applications), approves special usage requests, and can remotely trigger device status checks or force lock operations. Furthermore, parental device 200 can also receive student learning assessment reports and behavioral habit warnings generated by the backend server 300 based on AI analysis, assisting parents in scientifically participating in their child's learning management process. Before completing the designated learning task, when a student uses a parent's or other device with this teaching management APP installed, after these devices identify the student, their operating systems will be locked to the learning task prompts and task execution interface, just like the student's device's operating system. Access to learning-related functional modules (such as viewing task content, completing assignments, watching teaching videos, and reviewing incorrect answer explanations) is only permitted, while access to entertainment applications, social platforms, games, browsers, and other unauthorized functions is prohibited.

[0034] The backend server 300 is deployed in a cloud data center and includes a database module, a computing center module, and a communication interface module. The database module stores basic student user information, historical homework data, error records, knowledge point mastery maps, learning task logs, device usage data, and a teaching resource library (including textbooks, courseware, exercise sets, instructional videos, and extracurricular books). The computing center module is equipped with an artificial intelligence algorithm engine and AI data model to automatically analyze and process received learning data, enabling functions such as homework correction, identification of knowledge weaknesses, personalized learning content creation and learning path planning, and dynamic learning task generation. For task results with semantic ambiguity or difficulties in recognizing complex graphics, the system can pop up a manual review window for teachers or backend operators to intervene and make a judgment. The communication interface module supports secure encrypted communication with student devices 100, parent devices 200, electronic workbooks 400, and teacher devices 500, using HTTPS / TLS protocols to ensure data transmission security and supporting offline caching and breakpoint resume mechanisms to ensure reliable data synchronization even in unstable network environments.

[0035] The Electronic Workbook 400 is a hardware device with a size similar to a traditional paper workbook, making it easy to carry and use, and also environmentally friendly. Its main hardware components include an e-ink display unit, a handwriting sensor layer and electronic pen, a camera module, a voice component, a central processing unit, a local storage unit, a wireless communication module, and a power management unit. The e-ink display unit uses backlight-free e-ink display technology to simulate the reading and writing experience of paper, effectively reducing the impact of prolonged use on students' eyesight. The handwriting sensor layer, in conjunction with a dedicated electronic pen, supports high-precision pressure-sensitive writing, allowing students to complete various handwritten assignments on the screen, such as math calculations, Chinese composition, and English vocabulary memorization. The original handwriting is saved in real time and can be converted into structured text data through OCR + semantic understanding technology. The camera module can be used to photograph paper test papers or homework; the system automatically crops and corrects the image and extracts the questions and content, automatically generating text data, which is then matched with a background question bank for intelligent recognition and classification. The voice component can be used to play text files and audio files. The device can record audio files and parse them into text data; the central processing unit runs an embedded operating system, integrating functions such as local homework completion and submission, homework correction, review of incorrect questions, learning analysis, access to teaching resources and annotation; the wireless communication module supports Wi-Fi or cellular network connection, uploading the homework data completed by students to the backend server 300 in real time, and simultaneously receiving relevant feedback information and calculation results sent from the backend server 300 to the electronic workbook 400; the device has built-in auxiliary learning tools such as a timetable, calculator, dictionary, notebook, and knowledge point extension database, but all functions are subject to system permission policies and cannot be accessed arbitrarily before the learning task is completed.

[0036] The teacher-side device 500 is a hardware device, which can be an electronic workbook, a desktop computer, or a regular tablet computer, etc. It is mainly used for assigning homework, grading homework, collecting student learning information, preparing lessons, and assisting in teaching.

[0037] Please refer to Figure 2 This is a block diagram of a teaching control device. The device includes a memory 10, a processor 20, a communication module 30, a display (not shown), and input / output terminals (not shown). The memory 10, processor 20, and communication module 30 are electrically connected directly or indirectly to achieve data transmission or interaction. For example, these components can be electrically connected through one or more communication buses or signal lines.

[0038] The memory 10 is used to store programs or data. The memory 10 may be, but is not limited to, random access memory (RAM), read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), etc.

[0039] The processor 20 is used to read / write data or programs stored in the memory 10 and to perform corresponding functions.

[0040] The communication module 30 is used to establish a communication connection between the server and other communication terminals through the network, and to send and receive data through the network.

[0041] It should be understood that, Figure 2 The structure shown is only a schematic diagram of the teaching control equipment; the teaching control equipment may also include... Figure 2 The more or fewer components shown, or having the same Figure 1 The different configurations shown. Figure 2 The components shown can be implemented using hardware, software, or a combination thereof.

[0042] The teaching management method provided in the embodiments of the present invention will be described in detail below.

[0043] Please refer to Figure 3 The teaching management method includes steps S101 to S103.

[0044] S101 receives the learning task for the current task cycle from the backend server.

[0045] The learning tasks include homework assigned by teachers, homework assigned by parents, and learning or practice content generated by the backend server based on the students' historical learning data on the electronic workbook 400, student device 100, and parent device 200, after analyzing their mastery of knowledge points.

[0046] At the start of each preset task cycle (e.g., 00:00 daily or after each class), student device 100 receives the learning task for the current task cycle from the backend server 300 via a wireless communication module. The learning task is transmitted in the form of structured data packets, containing two parts: Homework assigned by teachers is entered into the system by the teachers through their teaching terminals and synchronized to student devices 100, parent devices 200, and electronic workbooks 400 via the back-end server 300. The content covers written assignments, reading tasks, memorization requirements, etc. for various subjects. Personalized learning and practice content is automatically generated by the AI ​​algorithm engine and AI data model in the backend server 300 based on the analysis of the student's historical learning data on the electronic workbook 400, student device 100, and parent device 200. Specifically, it includes question types for redoing wrong questions, training courseware and exercises to strengthen weak knowledge points, and extension and improvement questions.

[0047] Historical learning data includes, but is not limited to: past homework accuracy rates, frequency of incorrect answers, time spent answering questions, and trends in the knowledge point mastery graph. The backend server uses machine learning models to identify knowledge points that students have not yet mastered and intelligently pushes targeted supplementary learning and practice content accordingly, ensuring that learning tasks both cover the requirements of the teaching syllabus and reflect individual differences.

[0048] The received learning tasks are stored locally in the non-volatile memory of the student device 100, and the task list, estimated completion time and priority indicators are displayed synchronously on the device's main application interface, lock screen interface and electronic workbook 400 to guide students to complete the tasks in an orderly manner.

[0049] S102: When a student user is detected attempting to use the teaching control device during the current task cycle, a preset interface is entered, and it is determined whether the learning task has been completed.

[0050] Students typically use the electronic workbook 400 (preferred) and student device 100 to complete their learning tasks. If the electronic workbook 400 and student device 100 are not readily available, students can use parent device 200 to complete their learning tasks. Therefore, regardless of whether the student uses student device 100 or parent device 200, if the system detects that the student user is attempting to launch or switch to functions that are not part of the teaching and control apps, such as game apps, short video platforms, social software, browsers, or music players, the operating system of student device 100 or parent device 200 will not support the corresponding operation or will immediately interrupt the current operation process and forcibly redirect to the preset interface.

[0051] The default interface is a full-screen modal window that cannot be closed by swiping, using the back button, or other conventional interaction methods. Within this interface, the system calls the local cache or sends a real-time query request to the backend server (300) to obtain the execution status of all pending learning tasks within the current task period, determining whether all tasks are completed and all grading results are correct.

[0052] The completion criteria include: all homework assigned by teachers and parents has been submitted on the electronic workbook 400, student device 100, or parent device 200; practice questions pushed by the backend server 300 have been completed and uploaded; the backend server 300 has completed automatic grading, and all questions have been answered correctly; if there are incorrect questions, the review of incorrect questions, learning of knowledge points, and re-practice of similar question types have been completed as required, and all questions have been answered correctly in the end.

[0053] S103, if the learning task is not completed, then during the current task cycle, access to functions on the teaching management device that do not belong to the learning application will be restricted, and the list of learning tasks to be completed and the progress bar will be displayed on the lock screen and main screen of the teaching management device.

[0054] If step S102 determines that the current learning task has not been fully completed, the student device 100 and parent device 200 enter permission restriction mode and implement the following control policies: Access to all applications and services not belonging to the teaching management APP software is prohibited; only authorized learning-related functions are allowed, including viewing task details, completing assignments, watching accompanying teaching videos, reviewing incorrect question analyses, using dictionary tools, and accessing the timetable; a list of learning tasks to be completed is displayed prominently on the lock screen and main interface of the student device 100 and parent device 200, including the title of each task, its subject, the number of remaining questions, and the estimated time; a progress bar for the overall task completion is also displayed, dynamically updated as a percentage, to help students intuitively understand their current progress and create positive motivation; gentle reminder notifications are popped up periodically according to set rules (such as "30% of the task is not yet completed; once completed, you can use the phone normally") to avoid excessive interference while maintaining continuous guidance.

[0055] based on Figure 3 Please refer to Figure 4 The teaching management method also includes steps S104 to S105.

[0056] S104. If a student user submits task completion data within the current task period, the task completion data is sent to the backend server so that the backend server can determine whether the learning task is completed based on the task completion data.

[0057] The task completion data includes students' answers and their original handwriting information collected through electronic workbooks, student devices, and parent devices, as well as audio, images, or videos of the answers collected through electronic workbooks, student devices, and parent devices.

[0058] After a student completes all learning tasks within the current task period, the task completion data is sent to the backend server 300 so that it can determine whether the learning tasks have been truly completed.

[0059] Task completion data is collected, packaged, and uploaded via the electronic workbook 400, student device 100, or parent device 200. Specifically, when using the electronic workbook 400 to complete assignments, its built-in handwriting sensor layer and electronic pen record the student's handwritten answers on the e-ink screen and their corresponding original handwriting information in real time, including but not limited to: stroke trajectory coordinate sequences; writing pressure change curves; start and end timestamps; stroke order and correction marks (such as erased and rewritten areas).

[0060] The aforementioned original handwriting information serves as an important data source for learning behavior analysis. It not only reconstructs the actual answering process and trains students' handwriting skills and habits, but also helps identify students' thought processes, problem-solving habits, and levels of concentration. For example, frequent revisions, long pauses, or skipping steps in answering questions may reflect problems such as weak grasp of knowledge points or inattentiveness.

[0061] The task completion data is packaged into a data structure containing the following fields: student identity identifier (ID); current task period identifier; answer result for each question (image + structured text); original handwriting data stream; submission timestamp; device signature and integrity verification code (to prevent tampering). The data packet is uploaded to the backend server 300 via an encrypted channel (such as HTTPS / TLS) through a wireless communication module. After receiving the data, the backend server 300 initiates an automatic grading process: first, it uses OCR technology and a semantic understanding model to convert the handwritten content into an analyzable text format, and then compares and verifies it against the standard answers in the question bank; for subjective questions (such as essays and application questions), it uses AI deep learning-based natural language processing algorithms for multi-dimensional evaluation (content completeness, logic, keyword coverage, etc.).

[0062] If all questions are answered correctly and there are no incomplete items, a "task completed" result will be generated; if there are incorrect questions, a subsequent incorrect question reinforcement mechanism will be triggered, and the task will not be considered completed at this time.

[0063] S105: When the background server returns a message that the task has been completed, the access restrictions on functions of the teaching management and control device that are not part of the learning application are lifted, allowing student users to use all functions of the teaching management and control device.

[0064] Once the backend server 300 has finished processing the task completion data and confirmed that the student user has met all the requirements of this round of learning tasks, it sends a "task completed" message (i.e., permission unlocking command) to the student device 100, parent device 200, and electronic workbook 400. This message contains a digital signature and a time-limited tag to ensure secure transmission and prevent replay attacks.

[0065] Upon receiving this message, student device 100, parent device 200, and electronic workbook 400 shall perform the following operations: verify the legality and integrity of the message source; clear local function access restriction policies; remove the blocking status of applications that are not part of the teaching control APP software; restore the normal operating system mode, allowing students to freely use previously restricted functions such as games, social networking, videos, browsers, and extracurricular reading materials; Optionally, a positive feedback prompt can be displayed on the main interface, such as "Congratulations on completing today's learning task! You can now use your phone normally" to enhance the incentive effect.

[0066] Based on step S105 above, this embodiment of the invention further provides an optional parental involvement management mode: even if the backend server 300 has determined that the learning task is completed and sent a "task completed" message to the student device 100, it can still dynamically decide whether to actually lift the access restrictions on functions on the student device 100 that are not part of the teaching management APP software based on remote instructions sent by the parent device 200. This mechanism allows parents to flexibly exercise final control based on the student's overall behavior, schedule, or other educational considerations.

[0067] Upon receiving the "task completed" message from the backend server 300, student device 100 does not immediately unlock all functions automatically, but instead enters a conditional pending unlock state. At this time, a notification is pushed to the bound parent device 200 through the communication interface module, prompting "Your child has completed the current learning task. Do you wish to allow them to use the entertainment function?" along with task completion details (such as completion time, time consumption statistics, review of incorrect questions, etc.) for parents to consider when making a decision.

[0068] Parents can respond through the teaching management APP interface on the parent device 200 and choose to send one of the following two types of commands: Control Release Instruction: This indicates that parents agree to allow students to use electronic devices normally after completing their learning tasks. Upon receiving this instruction, Student Device 100 will immediately perform a permission release operation, removing access restrictions on applications that are not subject to educational control (such as games, short videos, social media, etc.), and restoring the device's full functionality. Continued Control Instruction: This indicates that parents are temporarily not allowing students to use functions of apps not included in the teaching control software, possibly due to the following considerations: the current time is too late (e.g., close to bedtime), the student has completed the task but with a perfunctory attitude, or there are other violations (e.g., delayed submission, multiple incorrect re-submissions). In this case, the student's device will remain restricted, and the main interface and lock screen will continue to display the message "Task completed, but usage permissions are controlled," maintaining the original function blocking policy.

[0069] It should be noted that parental instructions can be confirmed through various interactive methods, including but not limited to: a single manual click for confirmation; automatic triggering of preset rules (e.g., "Entertainment functions are not allowed to be used after 9 pm from Monday to Friday, even if the task is completed"); and a multi-level approval mechanism (applicable to scenarios with multiple guardians, requiring the consent of at least two parents to unlock).

[0070] In addition, to prevent students from being unable to use the device properly due to parents' prolonged lack of response, a default handling strategy can be set. For example, if parents do not respond within a preset time limit (such as 30 minutes), the pre-set "default unlock strategy" can be automatically executed—configurable as "automatic unlock" or "keep locked," which parents can choose in the initial settings.

[0071] By introducing the remote intervention capability of parental devices 200, this embodiment of the invention achieves an organic integration between automated judgment and the will of family education. On the one hand, it retains the objectivity and efficiency advantages brought by the AI-driven task verification mechanism; on the other hand, it gives parents the necessary educational leadership, avoiding the drawbacks of "mechanical achievement equals laissez-faire," making the use and management of electronic products more scientific, reasonable, and educationally conscious.

[0072] The dual verification mechanism is particularly suitable for guiding the behavior of students of different age groups: for older students with strong self-discipline, it can be set to "automatic unlocking as the main method and parental supervision as the secondary method"; while for younger students or students with weaker self-control, the "mandatory parental approval" mode can be enabled to achieve stricter usage control.

[0073] based on Figure 4 Please refer to Figure 5 The teaching management method also includes step S106.

[0074] S106, if the background server returns a message that the task is not completed, the unfinished part of the learning task will be postponed to the next task cycle, and access to functions that do not belong to the learning application on the teaching management device will be continuously restricted in the next task cycle until the learning task is completed.

[0075] When a student user has submitted all assignments within the current task period (e.g., before 24:00 on the same day), but after being graded by the backend server 300, there are incorrect questions and the system's required error correction training process has not been completed, the computing center module determines the overall status of the learning task as "incomplete" and sends a "task incomplete" message to the electronic workbook 400, student device 100, and parent device 200.

[0076] Upon receiving this message, the electronic workbook 400, student device 100, and parent device 200 perform the following operations: Mark the unsubmitted, unsuccessful, or reworked portions of the original task (including unfinished assignments from teachers and parents, and system-generated reinforcement learning and exercises) as "tasks to be continued"; include them in the learning task list for the next task cycle, displaying them together with the new cycle's task content; synchronously update the task status on the electronic workbook 400, student device 100, and parent device 200, clearly identifying which tasks are "legacy tasks"; continue to maintain access restrictions on functions on student device 100 and parent device 200 that are not part of the teaching management app, i.e., prohibit the use of entertainment applications such as games, social media, and videos, ensuring that students cannot evade their unfinished learning responsibilities by skipping cycles.

[0077] In addition, to avoid excessive psychological pressure or resistance from students due to task backlog, intelligent optimization can be performed based on preset strategies. For example, tasks that have been incomplete for a long time can be prioritized and a special reminder can be displayed; if a task related to a certain knowledge point has been incomplete multiple times, a simplified introductory question can be generated to reduce the initial difficulty and help students build confidence; the total number of subsequent tasks can be dynamically adjusted based on AI analysis results, and the number of new tasks can be appropriately reduced to free up time to complete the remaining content; a warning notification can be sent to the parent's device 200: "Your child has X tasks that have been incomplete for a consecutive period of time. Please pay attention to their learning status" so that parents can intervene in time to provide guidance or adjust the plan.

[0078] Through the above mechanism, this embodiment of the invention achieves continuous tracking and mandatory closed-loop management of learning tasks across cycles, eliminating speculative behaviors (such as deliberate delays and selective completion) caused by "reset upon expiration" management, and ensuring the comprehensive implementation of teaching objectives. At the same time, the task extension mechanism is not simply repetitive, but rather continuously optimizes the pushed content based on the student's actual mastery, reflecting an organic combination of personalized education and rigid institutional constraints.

[0079] based on Figure 5 Please refer to Figure 6 The teaching management method also includes step S107.

[0080] S107 If a student user does not submit task completion data within the current task cycle, the learning task will be postponed to the next task cycle, and access to functions that do not belong to the learning application on the teaching management device will be continuously restricted in the next task cycle until all learning tasks are completed.

[0081] Before the end of each task cycle (e.g., 24:00 daily), the backend server 300 automatically checks whether the student user has uploaded the corresponding learning task completion data via the electronic workbook 400, student device 100, or parent device 200. Valid submission of "task completion data" is based on receiving the structured data packet and completing the integrity verification; data that is only saved locally but not successfully uploaded is not considered submitted.

[0082] When it is confirmed that there are no submission records within the deadline, the following processing flow is executed: Mark the task status as "overdue and not submitted" in the database module; automatically generate a behavior log to record the time of non-submission, task content, and related knowledge points for subsequent learning analysis; migrate the original learning tasks (including homework assigned by teachers and parents and personalized learning and practice content generated by the system) to the task queue of the next task cycle and display them as "tasks to be completed" with priority; at the same time, push a reminder notification to parent device 200: "Your child has not submitted homework for subject XX today. Please pay attention to their learning progress," allowing parents to remotely view task details and provide supervision; after entering the next task cycle, student device 100 and parent device 200 continue to maintain access restrictions on functions that are not part of the teaching management APP software, and the main interface and lock screen continuously display the prompt message "There are still historical tasks that have not been submitted. Please complete the remaining tasks first," and highlight the unsubmitted task items.

[0083] It should be noted that "not submitted" in this step is different from "submitted but not approved," representing a more serious case of task execution failure. Therefore, a differentiated response mechanism can be set up at the strategy level. For example, for students who fail to submit tasks twice consecutively, their task monitoring level can be automatically increased, real-time location tracking can be enabled (e.g., requiring completion only in a home network environment), a manual review process can be added, or a mandatory parental approval mode can be triggered; a "task reminder" voice reminder function can be activated on the electronic workbook 400 (e.g., playing a gentle prompt tone at a fixed time every day); new extended practice content can be temporarily suspended, and resources can be concentrated on guiding students to complete the backlog of tasks to avoid a snowball effect.

[0084] In addition, to prevent misjudgment as "not submitted" due to objective reasons such as network anomalies or equipment failures, the teaching management system has a fault tolerance mechanism: if a student has completed writing locally and attempted to upload, but failed due to a temporary network outage, it will be automatically re-uploaded the next time the network is connected, and the backend server will determine whether it is within a reasonable delay range by combining the timestamp, thus removing the "not submitted" mark.

[0085] Through the above mechanism, this invention achieves comprehensive supervision of learning task execution behavior—whether submitted but not approved or not submitted at all, no one can escape responsibility. All incomplete tasks will be continuously tracked and extended cycle by cycle until the loop is completely closed. This design fundamentally eliminates the possibility of students evading their learning obligations by "pretending not to see" or "forgetting to submit," ensuring the seriousness and enforceability of teaching management rules. It is particularly suitable for students with weak self-discipline and a strong tendency to procrastinate, effectively establishing the behavioral habits of "tasks not left unfinished overnight" and "doing today's work today." Long-term operation helps improve learning attitude and time management skills.

[0086] Furthermore, the electronic workbook 400 and student device 100 also push task status notification messages to parent device 200 in real time. Through information synchronization between the electronic workbook 400, student device 100, and parent device 200, parent users can be informed of the execution process and completion status of learning tasks, as well as the usage of other application software by students that is not part of the learning application.

[0087] Task status notifications are displayed on the lock screen of the parent's device or the main interface of the app in the form of text, voice reminders or pop-ups, ensuring that parents can be informed of their child's learning progress even if they do not actively check the screen.

[0088] In addition, parents can access the app by clicking on the notification to view the specific content of the task, the task completion process and results, the writing trajectory (handwritten records from the electronic workbook), the error analysis report, and personalized learning suggestions, thereby achieving transparent supervision and effective participation in their children's learning process.
