Taking high school biology test as an example, this study analyses the test questions in terms of unidimensionality test, test paper fit, items fit, Wright map and bubble chart, and analyses the test items by combining the data with the contents of the test items. Based on the results of the data and the analysis of the items, it is proposed that test items should be analysed by combining the data with the contents of the test questions, reasonably setting the question difficulty coefficients, and improving the scientificity and differentiation of the structure of the test paper;innovative forms of test items and strengthening the design of life situations.展开更多
