Abstract The cognitive diagnosis of “redox reactions” in senior high school was carried out by using Rule Space Model as a cognitive diagnostic analysis tool. It is found that the six cognitive attributes of “redox reactions” in senior high school are divided reasonably, the classification proportion of reaction mode is 97.40%, and the knowledge state of the subjects can be clustered into 13 kinds, of which the proportion of 6 kinds of knowledge state is higher. There are differences in students' mastery of different attributes, in which the mastery rate of attributes C1 and C2 is more than 97%, while the mastery rate of attribute C6 (calculation of redox reactions) is only 31.47%, which needs to be remedied. The results of cognitive diagnosis, which can be classified and personalized, are helpful for teachers to carry out scientific and reasonable remedial teaching.
