[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0020] In this embodiment, an electronic device is provided, including a memory and a processor. The memory stores a computer program, and the processor is configured to run the computer program to execute the method in the following embodiments.

[0021] The present application is described with reference to the flowcharts and / or block diagrams of the methods, devices (systems), and computer program products according to the embodiments of the present application. It should be understood that each process and / or box in the flowchart and / or block diagram, as well as the combination of the processes and / or boxes in the flowchart and / or block diagram, can be implemented by computer program instructions. These computer program instructions can be provided to a processor of a general-purpose computer, a special-purpose computer, an embedded processor, or other programmable data processing device to generate a machine, so that the instructions executed by the processor of the computer or other programmable data processing device generate instructions for implementing the processes in the flowchart and / or block diagram. Figure 1 A process or multiple processes and / or boxes Figure 1 A device that provides the functions specified in a block or multiple blocks.

[0022] These computer program instructions may also be stored in a computer-readable memory capable of directing a computer or other programmable data processing device to operate in a specific manner, so that the instructions stored in the computer-readable memory produce an article of manufacture comprising an instruction device, which implements the process Figure 1 A process or multiple processes and / or boxes Figure 1 A function specified in one or more boxes.

[0023] These computer program instructions can also be loaded onto a computer or other programmable data processing device so that a series of operating steps are executed on the computer or other programmable device to produce a computer-implemented process, thereby providing instructions for implementing the process. Figure 1A process or multiple processes and / or boxes Figure 1 The steps for the functions specified in one or more boxes.

[0024] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0025] In this embodiment, a method for processing mathematics teaching result evaluation data is provided. Figure 1 is a flow chart of a method for processing mathematics teaching result evaluation data according to an embodiment of the present application. Figure 1 As shown, the process includes the following steps:

[0026] Step S102, the first software scans the first QR code set in the predetermined classroom;

[0027] As an optional implementation, the QR code is generated based on the classroom identification information and course information and an increasing number, which increases from 1. Each time the QR code is scanned, the generated number increases by 1 and a new QR code is generated based on the increased number. When a QR code is scanned, the QR code that identifies the number in the server has been scanned. At this time, the QR code is refreshed, and the refreshed QR code is generated based on the new number, so that a QR code can only be scanned once. The method of students taking photos to send QR codes to classmates who are not in class is not feasible.

[0028] After the class starts for a scheduled duration (e.g., half an hour), the server sends a clear message to the device placed in the classroom, which is used to instruct the deletion of the displayed QR code and display the subject currently being taught and the end time of the class.

[0029] After the QR code is deleted, the server obtains the final value of the incremental number and calls the camera on the device placed in the classroom to take a photo of the classroom. The number of students in the photo is identified, and the identified number is confirmed with the final value, and the confirmation result is sent to the second software. The number and the final value are also used to compare the number of answers finally received.

[0030] There are many ways to identify the number of students from photos. A machine learning model can be trained through a neural network. This model is called the third model. The third model is trained using multiple sets of training data. Each set of training data includes configured input data and configured output data corresponding to the input data, wherein the input data is a photo, and the output data is a label, which is used to identify the number of people in these photos. The third model can be used after training. The server inputs the photo into the third model, and the third model outputs the number of people. Adjust the angle of the camera so that the camera cannot capture the teacher. Or if the teacher is captured, the number of people will be reduced by 1.

[0031] Step S104, the first software opens the sign-in page corresponding to the reserved classroom through the first QR code, and sends sign-in information through the sign-in page, wherein the sign-in information includes: the student's identification information, the time of scanning the QR code, and the geographical location information of the first mobile terminal, wherein the identification information is used to uniquely identify the identity of the student, and the first software is installed on the first mobile terminal;

[0032] Step S106, the server determines the subject and teacher for teaching according to the scheduled classroom and time, where the server may refer to software or services running on the server;

[0033] Step S108, the server records the students who have sent the sign-in information, and sends the identification information of the students who have sent the sign-in information to the second software, wherein the teacher logs in to the second software;

[0034] Step S110, the second software sends test questions to the server during the teaching time of the subject;

[0035] Step S112, the server sends the test questions to all first software whose sign-in information has been recorded by the server, and receives the answers to the test questions fed back by the first software within a predetermined time range (requiring students to write them down on paper and take photos), and saves them; wherein the sign-in information and the answers to the test questions are used to evaluate the teaching results of the students.

[0036] In an optional embodiment, after receiving all the answers, the server searches for identical answers among all the answers, marks the identical answers found, and feeds back the search results to the corresponding students, wherein identification information of the students with identical answers is obtained, and the search results are sent to the corresponding first software based on the identification information.

[0037] There are many ways to find similar answers. For example, a machine learning model can be trained through a neural network. The model is called the first model. The first model is trained using multiple sets of training data. Each set of training data includes configured input data and configured output data corresponding to the input data. The input data is multiple photos of answers to questions, and the output data is a label. The label is used to identify which of these photos are similar. After the first model is trained, it can be used. The server inputs all photos corresponding to the answers into the first model, and the first model outputs identification information for identifying which are similar.

[0038] There are many ways to determine whether the answer is correct. For example, scan a photo with the answer and extract the text and symbols in the photo, and convert the answer in the photo into editable text and symbols. Regenerate a second photo with these editable text and symbols in a predetermined format, and compare the second photo with a pre-saved photo of the correct answer, which is also generated using a predetermined format, so that the font and size of the second photo and the correct answer photo, as well as the position of the answer in the photo, are the same; determine the score corresponding to the answer based on the comparison result. This is an intelligent implementation method. After determining the score, the answer and score are sent to the corresponding student. The student uses the first software to feedback whether there is any doubt about the score. If there is any doubt, the teacher will make manual corrections.

[0039] There are many ways to compare photos. For example, a machine learning model can be trained through a neural network. This model is called the second model. The second model is trained using multiple sets of training data. Each set of training data includes configured input data and configured output data corresponding to the input data. The input data is two photos of the answers to the questions, and the output data is a label. The label is used to identify the percentage of the two photos that are the same. After the second model is trained, it can be used. The server inputs the photos into the second model, and the second model outputs the percentage. The score in the percentage is the final score. For example, 95%, the final score is 95 points.

[0040] Through the above steps, attendance can be recorded through the server, and a test question can be sent in each class, combining daily tests with attendance. In addition, only students who have signed in can take the test, and finally save the sign-in information and test results, which are used to evaluate students. Therefore, the above steps solve the problem that traditional teaching result evaluation methods cannot urge students to learn, and to a certain extent, they have achieved the purpose of promoting learning and improved the accuracy of teaching result evaluation.

[0041] As an optional implementation, after the end of the semester, the scores of each answer of the student are summed up to get the total score, and then the total score is divided by the number of questions asked by the teacher to get the average score. If a student is absent from class, he must be missing at least one answer, but the denominator is all the questions asked by the teacher, so the student's score will inevitably be lower. Therefore, this assessment method not only assesses the student's learning results, but also indirectly assesses the student's attendance.

[0042] In order to prevent students' scores from being tampered with, all answers obtained are encrypted after the assessment is completed, and the encryption key uses the password used by the student to log in to the school teaching system.

[0043] As another optional implementation, the server may save the encrypted answer, and the server sends the answer to an endorsement node; the endorsement node is a type of node in the blockchain, and the endorsement node is used to generate an endorsement signature for each received answer and send the signed answer to the server; the server is used to endorse the answer into a payload and broadcast it to the sorting service node; the sorting service node is used to put the sorted answer into a block and send it to all nodes in the channel, the sorting service node is a type of node in the blockchain, and the sorting service node provides a shared communication channel and provides broadcast services for messages containing answers; the block is used to generate a blockchain, and the block includes at least one encrypted answer and a timestamp of the block.

[0044] For each blockchain generated, the first software sent to each student who submitted the answer is saved locally, which is more secure.

[0045] Preferably, the server records the students whose sign-in information has been sent, including: the server determines whether the geographic location information of the first mobile terminal is within a predetermined range, wherein the predetermined range is determined based on the pre-configured geographic location of the classroom; if it is within the predetermined range, the server records the sign-in information sent by the first software, otherwise it does not record it.

[0046] Preferably, the QR code is displayed through the third software, and the third software runs on a device placed in the classroom.

[0047] Preferably, the display screen of the device placed in the classroom is an ink screen.

[0048] Preferably, before the first software scans the first QR code set in the predetermined classroom, the method further includes: the server pre-generates the first QR code at least based on the classroom identification; the server sends the QR code to the device placed in the classroom before each subject starts according to the time information in the pre-saved class schedule of the classroom.
