Comprehensive ability evaluation system
2022-07-06 04:04:00 【Try your best】
Purpose
Design and expand a comprehensive ability evaluation system . The system can realize menu selection self-test mode 、 Game mode 、 Difficulty and number of questions , In Canada 、 reduce 、 ride 、 In addition to the test module to achieve integration 、 Tips for correct and wrong questions 、 Wrong question set collection function , Realize scoring and ranking function in phased test , Through the game module to achieve entertainment functions .
Operation result diagram
Function is introduced
The comprehensive ability evaluation system is a system for primary school students to test the operation ability of addition, subtraction, multiplication and division
1. User rights guarantee
First, choose login or registration through the character interface , Then choose teachers or students . Then jump to the login or registration interface , Enter a name 、 Student ID and password . Login screen . If the program cannot retrieve the target account whose name and student number match the local file , Then return an error message and prompt that your account does not exist , Login interface if the program retrieves the target account whose name and student number match the local file, but the password does not match , Then return an error message and prompt that your password is incorrect .
2. Choose a test
In the main menu, select addition, subtraction, multiplication and division or comprehensive random test according to the prompt of the character interface and the corresponding keyboard input , Then choose the number and difficulty of questions one by one , The program will automatically generate the corresponding difficulty and number of questions for students , And show the student after the student saves it （ she ） Scores and the number of correct questions .
3. Ranking and error checking
In the periodic test , The program will give students points according to the difficulty and correctness of the questions. Students will update the accumulated points for each question they complete in the test , And after the students save the test results, update the total points for students to rank , Both students and teachers can check the ranking and wrong questions （ The wrong question set only records the addition, subtraction, multiplication and division modules Wrong question ）.
The expanded functions of this group include ： Set up a simple 、 Ordinary and difficult three kinds of difficulty , The integration method is reasonably arranged with the difficulty , Avoid blindly brushing points ; Wrong record , The set of wrong questions and the number of wrong questions are better consolidated and improved ; User evaluation , Give encouragement and suggestions in time ; There is ranking incentive effect .
