Abstract:

Multiple-Choice (MC) item format is commonly used in cognitive diagnosis assessment. To obtain much more diagnostic information from MC items, including the diagnostic information of the keys and the distractors, the methods to construct MC items are firstly introduced. To extract the diagnostic information of the keys and the distractors, some corresponding cognitive diagnosis models are also proposed. Finally, the article suggests that the researches on the methods to construct distractors and cognitive diagnosis models to extract diagnostic information from the distractors should be strengthened.

Key words: cognitive diagnosis, multiple choice items, distractors, diagnostic information
