In this embodiment, a method for processing mathematical education result evaluation data is provided, and fig. 1 is a flowchart of a method for processing mathematical education result evaluation data according to an embodiment of the present application, and as shown in fig. 1, the flowchart includes the following steps:
step S102, scanning a first two-dimensional code arranged in a predetermined classroom by first software;
as an alternative embodiment, the two-dimensional code is generated according to the classroom identification information and the course information and an incremental number, the incremental number is increased from 1, after the two-dimensional code is scanned, the number is increased by 1, and a new two-dimensional code is generated according to the increased number. When a two-dimensional code is scanned, the two-dimensional code for identifying the number in the server is scanned, at the moment, the two-dimensional code is refreshed, and the refreshed two-dimensional code is generated according to the new number, so that one two-dimensional code can only be scanned once. It is not feasible for students to use a photographing mode to send two-dimensional codes to students who are not in class.
After the class hour starts for a predetermined period (for example, half an hour), the server transmits a clear message for instructing deletion of the displayed two-dimensional code and displays the subject currently in class and the time of the next class to the device placed in the classroom.
After the two-dimensional code is deleted, the server obtains the final value of the incremented number and invokes a camera placed on a device in the classroom to take a picture of the classroom. And identifying the number of students in the shot picture, confirming the identified number and the final value, and sending a confirmation result to the second software. The number and final value are also used to compare the number of answers ultimately received.
The number of students identified from the photos can be obtained by various ways, and a machine learning model can be trained through a neural network, and is called a third model, the third model is obtained by training through a plurality of groups of training data, each group of training data comprises configured input data and configured output data corresponding to the input data, wherein the input data is the photos, and the output data is labels used for identifying the number of the photo persons. This third model is used after training, the server enters the photos into the third model, which outputs the number of people. The angle of the camera is adjusted, so that the camera cannot shoot teachers. Or it is photographed that the teacher reduces the number of people by 1.
Step S104, the first software opens a check-in page corresponding to the predetermined classroom through the first two-dimensional code and sends check-in information through the check-in page, wherein the check-in information comprises: identification information of a student, time for scanning the two-dimensional code and geographical location information of a first mobile terminal, wherein the identification information is used for uniquely identifying the identity of the student, and the first software is installed on the first mobile terminal;
step S106, the server determines the subject and teacher for teaching according to the predetermined classroom and time, wherein the server can be software or service running on the server;
step S108, the server records the students who send the check-in information and sends identification information of the students who send the check-in information to second software, wherein the teacher logs in the second software;
step S110, the second software sends a test subject to the server within the subject teaching time;
step S112, the server sends the test questions to all first software recorded with the sign-in information by the server, receives answers of the test questions fed back by the first software within a preset time range (the students are required to write on paper and take pictures), and stores the answers; wherein the check-in information and the answer to the test question are used for evaluating the student teaching result.
In an optional implementation manner, after receiving all the answers, the server searches for the duplicate answer among all the answers, marks the found duplicate answer, and feeds back a search result to a corresponding student, where identification information of the student of the duplicate answer is obtained, and the search result is sent to the corresponding first software according to the identification information.
For example, a machine learning model may be trained through a neural network, and the model is referred to as a first model, and the first model is trained by using a plurality of sets of training data, each set of training data includes configured good input data and configured output data corresponding to the input data, wherein the input data is a plurality of photos of answers to questions, and the output data is a label used for identifying which of the photos are identical. After the first model is trained, the server inputs photos corresponding to all answers into the first model, and the first model outputs identification information for identifying which ones are the same.
There are many ways to determine the answer is correct, for example, scanning the photo with the answer and extracting the characters and symbols in the photo, and converting the answer in the photo into the characters and symbols that can be edited. Generating a second photo by the editable characters and symbols according to a preset format again, comparing the second photo with a pre-stored correct answer photo, wherein the correct answer photo is generated by using the preset format, so that the fonts, the sizes and the positions of the answers in the second photo and the correct answer photo can be ensured to be the same; and determining the score corresponding to the answer according to the comparison result. This is an intelligent implementation, after determining the score, the answer and the score are sent to the corresponding student, and the student feeds back whether there is a question about the score through the first software, and in case there is a question, makes a manual correction by the teacher.
There are many ways to compare photos, for example, a machine learning model can be trained by a neural network, and the model is called a second model, and the second model is trained by using a plurality of 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 of two answers to questions, and the output data is a label used for identifying the same given percentage of the two photos. This second model may be used after training, the server entering the photos into the second model, the second model outputting a percentage, the fraction of which is the final score, e.g., 95%, and the final score is 95%.
Through the steps, the attendance checking condition can be recorded through the server, a test question can be sent in each class, the daily test and the attendance checking are combined, only signed students can participate in the test, and finally, the sign-in information and the test result are stored and are used for evaluating the students. Therefore, the steps solve the problem that the traditional teaching result evaluation method cannot prompt students to learn, achieve the aim of promoting learning to a certain extent, and improve the accuracy of teaching result evaluation.
As an alternative embodiment, after the school period is over, the scores of each answer of the student are summed to obtain a total of scores, and then the average score is obtained by dividing the total of scores by the number of questions asked by the teacher. If the student lacks lessons, at least one answer is necessarily lacked, but the denominator is all the questions the teacher has given, so that the score of the student is necessarily reduced, and the assessment mode not only assesses the learning result of the student, but also indirectly assesses the attendance condition of the student.
In order to prevent the scores of the students from being falsified, each answer is encrypted after the evaluation is finished for all the answers obtained each time, and the encryption key is used for the password of the student logged in the school teaching system.
As another alternative, the server may store the encrypted answer, and the server sends the answer to the endorsement node; the endorsement node is one of the nodes in the block chain, and is used for generating an endorsement signature for each received answer and sending the signed answer to the server; the server is used for endorsement of the answer into a payload and broadcasting the payload to the sequencing service node; the sequencing service node is used for placing the sequenced answers into the block and sending the sequenced answers to all nodes in the channel, the sequencing service node is one of the nodes in the block chain, and the sequencing service node provides a shared communication channel and provides broadcast service for the message containing the answers; the block is used for generating a block chain, and the block comprises at least one encrypted answer and a time stamp of the block.
For each generated blockchain, the first software sent to each student who submitted the answer is stored locally, so that the safety is improved.
Preferably, the student that the server records the sent check-in information includes: the server judges whether the geographical position information of the first mobile terminal is within a preset range, wherein the preset range is determined according to the preset geographical position of the classroom; and if the first software is within the preset range, the server records the check-in information sent by the first software, otherwise, the check-in information is not recorded.
