Abstract

A parameterization design and intelligent statistical method for on-line question bank. The invention introduces parameterization design into subject question library, and makes the parameter of the place needing to change in the question realize data randomization by designing random function template, and then compiles the question type of each subject of different subjects, and makes the parameterization of the existing on-line learning question library, namely, the effect of the same question stem and random data is achieved, and by designing intelligent discrimination function, after the answer is filled in by the person doing the question, the method also realizes intelligent discrimination, gives analysis, counts the error, gives feedback function, and the teacher inputs new question according to the feedback condition, thus the original question library is continuously enriched. The invention makes up the defects of the traditional question bank, fundamentally avoids the phenomenon of copying answers, replaces most of manual labor of teachers, and improves the working efficiency, thereby promoting the development of the informatization teaching field of China.

Description

Parameterized design and intelligent statistical method for online question bank

Technical Field

The invention relates to the field of information-based education. The programming software can be used for carrying out parameterization design on the original learning question bank efficiently and accurately, the effect of random data of the same question stem is achieved, a user can master the subject principle more skillfully, and the learning quality of the user is improved.

Background

The question bank is a system resource for providing alternative test questions for subject knowledge and skill testing, and is an important guarantee tool for learners to be proficient in learning subject knowledge. The theory supporting the problem bank construction at present mainly includes the Classical Test Theory (CTT) and the project reaction theory (IRT). The opinion of the modern remote education resource construction committee of education department on the construction of question banks requires that the guidance of classical measurement theory (CTT) be followed. The IRT theoretical basis is a potential idiosyncratic theory, and solves a plurality of problems which are solved by the CTT. However, the former has been developed more fully than the latter, and the latter has many disadvantages, such as large number of questions, which is easy for the learner to have poor learning experience and hinders the popularization.

Today, with the rapid development of "internet + education", the combination of scientific and technological products with education is a necessary trend. At present, more learning software, platforms and examination systems are combined with a traditional learning question bank, but the phenomena of homework plagiarism and examination cheating are continuous and serious, the credibility reflecting the real level data of students is lower and lower, and the independent and independent ability of the students in daily learning is also continuously reduced.

Disclosure of Invention

The invention discloses a method for parametrically designing mass learning questions. The method realizes automatic random generation of question data in a reasonable range by using a computer algorithm, so that when a user logs in a page to do the same question (examination and check point), the viewed question stems are the same, the data are random, after answering, the question making conditions are intelligently judged and counted, the learning conditions of students are fed back to teachers, cheating prevention is possible, and the workload of the teachers is greatly reduced.

The method comprises the following steps:

step one, designing a random function template, fixing the format of the template, and only changing the question data when compiling different questions

And step two, compiling different questions according to subject, subject type and difficulty coefficient to achieve the effect of random local data of subject stem and required change, thereby forming a parameterized question bank.

And step three, the teacher extracts multiple questions from the question bank to form the daily examination questions.

And step four, the students answer the questions by using the question making platform, the texts of the questions seen by each classmate are the same, and the data of the required change places are random and different.

And step five, after the answer is answered by the answerers, intelligently judging the correct and wrong conditions of the answers of the answerers, and giving evaluation, for example, taking a class as a unit, intelligently counting the correct rate of the same question, intelligently analyzing the difficulty and degree, and giving analysis on corresponding data of the test questions.

And step six, carrying out cloud synchronization on the data of the problem making condition, and feeding back the scores, the difficulty and the mastery degree of the problem and the knowledge points to the teacher.

And step seven, the teacher inputs the text and the data of the new question according to the feedback data and aiming at the difficult points and the error-prone points, and the new question is generated.

The computer algorithm comprises the steps of carrying out relevant compiling by using relevant functions in compiling software, designing a function template for making the theme data random, and filling the computer language in the template in the theme solving process, thereby greatly reducing the work intensity of compiling mass themes.

The design method realized by the invention can carry out statistics of the problem making situation through related application, and the data can truly reflect the learning level of learners.
