In this study, eight cognitive factors that stimulate the reading process
were identified by cognitive diagnosis, and the probability of each cognitive factor
being mastered by the examinee was calculated. Combining with expert opinions,
this paper analyzes the structural bias of reading test, and explores the relationship
between the examination structure and students’ reading ability. It is pointed out that
teachers should attach importance to the cognitive factor that has a low presence in
the examination and carry out special training for students. In order to improve the
“examination structure mechanism”, this study designed a cognitive diagnostic table in
order to comprehensively improve students’ reading level.
