The Application Of Item Response Theory In The Analysis Of High School Physical Choice

The analysis of test questions is an important part of education evaluation.The analysis of test questions can reflect the quality of test questions,reflect the problems in teaching,provide advice for the teaching process,and guide future questions.Most of the current analysis of the test questions is a qualitative analysis.Even the quantitative analysis adopts the Classical Text Theory.However,there are many limitations in the Classical Text Theory to measure the parameters of the test questions,and the Item Response Theory can well compensate the limitations of the Classical Text Theory.This study takes a multiple-choice question as an example,uses the Item Response Theory to quantitatively analyze the physics examination questions in middle schools,and serves as an attempted analysis of the analysis of test questions,providing an example of analysis of test questions for first-line education teachers and researchers.This article describes the research status of physical test analysis,and makes a comprehensive literature review on the status of Item Response Theory at home and abroad,explains the deficiencies in the analysis of the current high school physics test questions,and the advantages of the Item Response Theory in the analysis of test questions.According to the assumptions based on the Item Response Theory,the research materials were selected.The selected questions were five sets of questions that were collected from the physical multiple-choice questions of the comprehensive part of the first three college entrance exam simulation exams in the past five years in 17 cities in Shandong Province.Select a high school senior high school student in Shandong Province as a test to test questions,collect student test score data.Using the software EXCEL as a tool,using the Classical Text Theory to conduct statistical analysis of the measured data,using the software SPSS16.0,PARSCALE4.1 as a tool,using the Item Response Theory to conduct statistical analysis of the measured performance data to obtain two sets of project parameters,confirmed by comparison ItemResponse Theory has advantages in analyzing questions.Then the results of the item characteristic curve,item information curve,etc.,combined with the contents of the specific questions,as well as the questions of the teacher and the student,are analyzed from the overall questions,the individual questions and the comparison of the questions.The paper has obtained the model and method of analyzing the questions using Item Response Theory,and given some high school physics teaching suggestions and suggestions.The innovation of this paper lies in an empirical comparison between Classical Text Theory and Item Response Theory,and illustrates the advantages of Item Response Theory in the analysis of test questions.The Item Response Theory is used in the analysis of physical multiple-choice questions;the results of the analysis are compared with The content of the test questions is combined with quantitative analysis and qualitative analysis of the test questions,giving the teacher a specific example of analysis of test questions.
