Step S102: and calling a preset knowledge point database, and obtaining test knowledge points according to the knowledge point database and the class test questions of the students.
After the student answers are obtained through the electronic student certificates, the platform server calls a preset knowledge point database; the knowledge point database comprises questions, knowledge points and corresponding relations between the questions and the knowledge points; it can be understood that the knowledge point database includes test questions and knowledge points corresponding to the test questions, and then after the test questions are obtained, the knowledge points can be obtained according to the knowledge point database.
Step S103: and acquiring historical answer data of the student according to the electronic student card of the student, and selecting answer data related to the testing knowledge point from the historical answer data of the student according to the testing knowledge point.
It can be understood that the electronic student cards are provided with serial numbers, the serial numbers of the electronic student cards are stored in the platform server, each electronic student card is bound with one student, and a plurality of databases including historical answer databases of the students are also stored in the platform server; the historical answer database stores the serial number of the electronic student certificate of the student and the historical answer data of the student, so that the historical answer of the student can be acquired through the serial number of the electronic student certificate
Step S104: and analyzing according to the answer data and the answer result of the student to obtain the knowledge point mastery information of the student based on a preset knowledge point mastery analysis rule.
After the answer data and the answer result of the student are obtained, the student can be analyzed based on the analysis rule of the mastery degree of the knowledge points; specifically, comparing the number of titles with a preset number threshold, if the number of titles is smaller than the preset number threshold; obtaining the number of historical questions and historical answer results corresponding to each classroom test according to the answer data; calculating according to the number of the historical questions, the historical answer results and the classroom testing times to obtain the average accuracy; acquiring the number of questions of the classroom test of the student according to the electronic student certificate; obtaining the answer accuracy according to the number of the questions and the answer result; comparing the average accuracy with the answer accuracy to obtain an accuracy comparison result; the knowledge point mastery degree analysis rule comprises a correct rate sub-rule; and determining knowledge point mastery degree information of the student according to the accuracy sub-rule and the accuracy comparison result.
Judging the number of questions tested in a classroom, comparing the number of questions with a threshold value, and if the number of questions is small, analyzing the mastery degree of the knowledge points of the students by using a correct rate sub-rule; calculating the answer accuracy according to the number of the questions and the answer result, and then comparing the answer accuracy with the average accuracy; the average accuracy is obtained based on historical data, and the answer accuracy and the average accuracy are calculated according to the specified knowledge points; the degree of mastering the knowledge point by the student can be judged by comparing the answer accuracy with the average accuracy; if the answer accuracy is smaller than the average accuracy, the accuracy of the student answer in the classroom test is reduced, and the mastery degree of the student on the knowledge point is reduced; similarly, if the answer accuracy is higher than the average accuracy, the knowledge point mastery degree of the student is improved.
It is understood that the above process is the case of aiming at the situation that the number of subjects in the classroom test is small, but when the number of subjects in the classroom test is large, another way is needed to judge the mastery degree of the knowledge points by the students.
Specifically, comparing the number of titles with a preset number threshold, and if the number of titles is greater than the preset number threshold; obtaining historical answering time corresponding to each classroom test according to the answering data; calculating according to the historical answer time and the number of the historical questions to obtain average answer efficiency; acquiring the answering time of the classroom test of the student according to the electronic student certificate; obtaining the answering efficiency according to the answering time and the number of the questions; and comparing the answering efficiency with the average answering efficiency to obtain an efficiency comparison result.
When the number of the questions is increased, namely the number of the questions exceeds a number threshold, a new judgment rule needs to be substituted, so that the judgment on the mastery degree of the knowledge points by the students is more accurate; the knowledge point mastery degree is further judged by using the question answering efficiency; the answer efficiency can be calculated by using the number of the questions and the answer time, specifically, the answer efficiency can be obtained by dividing the number of the questions by the answer time, and the number of the questions per unit time can be calculated, namely the answer efficiency.
The knowledge point mastery degree analysis rule comprises an efficiency sub-rule, and knowledge point mastery degree information of the student is obtained according to the answer efficiency, the average answer efficiency, the answer correctness and the average correctness based on the efficiency sub-rule.
The specific steps of obtaining knowledge point mastery degree information of the students according to the answering efficiency, the average answering efficiency, the answering accuracy and the average accuracy based on the efficiency sub-rule comprise comparing the answering accuracy with the average accuracy and comparing the answering efficiency with the average answering efficiency; when the answer accuracy is higher than the average accuracy and the answer efficiency is higher than the average answer efficiency; obtaining improved marking information based on the efficiency sub-rule; when the answer accuracy is lower than the average accuracy and the answer efficiency is lower than the average answer efficiency; obtaining reduction marking information based on the efficiency sub-rule; when the answer accuracy is higher than the average accuracy and the answer efficiency is lower than the average answer efficiency, or when the answer accuracy is lower than the average accuracy and the answer efficiency is higher than the average answer efficiency; obtaining a correct rate difference value according to the answer correct rate and the average correct rate; and obtaining an efficiency difference value according to the answering efficiency and the average answering efficiency.
It should be noted that the knowledge point mastery degree information includes the increase mark information and the decrease mark information, the increase mark information indicates that the knowledge point mastery degree of the student increases, and the decrease mark information indicates that the knowledge point mastery degree of the student decreases.
Then based on the calculation rule contained in the efficiency sub-rule, obtaining knowledge point mastery degree information of the student according to the accuracy difference value and the efficiency difference value; the calculation rule comprises the steps of obtaining the ratio of the accuracy difference value to the efficiency difference value according to the accuracy difference value and the efficiency difference value; comparing the ratio with a preset threshold; if the ratio is larger than the threshold value, obtaining improved marking information according to the efficiency sub-rule; and if the ratio is smaller than the threshold value, obtaining the reduction marking information according to the efficiency sub-rule.
It can be understood that two concepts of question answering efficiency and question answering accuracy are introduced, so that the question answering time for students is certainly short, and the students can better master knowledge points by more questions; similarly, if the answer time is long and the accuracy is low, the students can not master the knowledge points well; both of these cases can be judged directly without further analysis.
But for the other two situations, namely the situation that the answering efficiency is high but the answering accuracy is low, and the situation that the answering efficiency is low but the answering accuracy is high; then further analysis of both data is required at this point; respectively calculating the difference between the answer correct rate of the test and the average correct rate representing the historical data, and the difference between the answer efficiency of the test and the average answer efficiency representing the historical data; the first difference value represents the difference between the accuracy of the test and the historical accuracy, and the second difference value represents the difference between the efficiency of the test and the historical efficiency; then calculating the ratio of the two, and comparing the ratio with a threshold value, wherein the ratio is obtained by dividing the correct rate difference by the efficiency difference; when the ratio is larger than the threshold value, the accuracy rate of each unit of efficiency is higher, and the knowledge point mastery degree of the student is improved; similarly, when the ratio is smaller than the threshold, the accuracy rate of each unit of efficiency is lower, and the mastery degree of the knowledge points of the student is reduced; by the mode, the knowledge point mastery degree of the student can be analyzed in detail aiming at tests under various conditions, and the report generated by the student is more detailed through the cooperation with the step S105, so that the management efficiency of the teacher to the student is improved.
Step S105: and generating a student analysis report according to the knowledge point mastery degree information based on a preset report generating rule.
The report generation rule refers to the analysis process of students, such as the change curves of different knowledge points of the students; the specific generation step of the change curve comprises the steps of obtaining the accuracy of different knowledge points in each test based on the historical data of students, constructing the change curve belonging to different knowledge points according to the test times and the accuracy, and reflecting the understanding and mastering degree of the different knowledge points in each test of the students through the change curve; through the change curve, a teacher can better understand and master the learning progress of students, and the management efficiency of the teacher to the students is improved.
In the embodiment of the application, the answering time and answering data of the post-course work of the student and knowledge points contained in the post-course work can be acquired through the electronic student certificate, wherein the post-course work comprises objective questions and subjective questions; matching the knowledge points with the operation questions according to a knowledge point database, and determining answer data and answer results of the questions corresponding to each knowledge point; calling historical knowledge points and corresponding historical answer information contained in the post-class homework of the student according to the electronic student certificate; matching the knowledge points with the historical knowledge points, and if the knowledge points and the historical knowledge points are successfully matched, obtaining mastery degree information of the knowledge points according to historical answer information, answer data and answer results; marking the knowledge points according to the mastery degree information of the knowledge points; the marks can indicate the mastery degree of the students on different knowledge points, the specific mark content can be 'increasing' and 'decreasing' according to the situation, when the knowledge points are marked with 'increasing', the test subject score of the knowledge points is higher, and when the knowledge points are marked with 'decreasing', the test subject score of the knowledge points is lower.
