Method for digitally evaluating difficulty of questions

Abstract

The invention discloses a method for digitally evaluating difficulty of questions. The calculation method is based on the following two steps: S1, basic assumption; s2, identifying and calculating answer keywords, and measuring the difficulty of questions according to the number and attributes of the answer keywords. On the basis of S1 and S2, the calculation method is used for evaluating the difficulty of questions of courses of different subjects and comprises the following steps that S01, parameters Sigma P =-ACGP + HKP + CFP + IP + SP + RP + RDP + CP + SRDP are calculated, and ACGP is an answer guessing parameter, wherein HKP is an implicit knowledge point parameter, CFP is a complex parameter, IP is an interference parameter, SP is a static parameter, RP is a reaction parameter, RDP is a reaction dynamic parameter, CP is a change parameter, and SRDP is a synthesis design parameter; and S02, a difficulty parameter of the question as DP is defined, and DP = AKP + Sigma P + Sigma WP+ Sigma LP is calculated. According to the calculation method, the difficulty of the questions is evaluated in advance by a digital means, so that the difficulty of the questions of different subjectscan be transversely compared.

Description

technical field [0001] The invention belongs to the technical field of teaching topic evaluation, in particular to a method for digitally evaluating the difficulty of a topic. Background technique [0002] In teaching and examination practice, it is necessary to control the amount of questions, the arrangement of question types, and the comprehensive difficulty of the test papers, so as to provide effective tools for testing the teaching effect, reasonably delineate the pass line (elimination rate) in advance, and compare with other test papers. The test results are compared horizontally. [0003] Generally speaking, there are two methods for evaluating the difficulty of test questions, one is measured difficulty, and the other is estimated difficulty. However, the methods used so far have certain problems. [0004] Difficulty determines the distribution of test scores, directly affects the evaluation and selection functions of the test, and has received high attention. T...

Problems solved by technology

But for exams with high testing requirements and confidentiality requirements, there will be several problems in doing so: What level of people should be selected for the test? How many people are involved in the test? How to ensure that it will not be leaked? And it is impossible to avoid the influence of human factors on the evaluation results

However, the evaluation results of this method are inevitably affected by the subjective will of proposition experts to a considerable extent.
