Testwiseness may introduce construct-irrelevant variance to multiple-choice test scores. Presenting response options sequentially has been proposed as a potential solution to this problem. In an experimental validation, we determined the psychometric properties of a test based on the sequential presentation of response options. We created a strong…

The effects of violating four item construction principles were examined to assess the validity of the principles and the importance of students' test wiseness. While flawed items were significantly less difficult than sound items, differences in item discrimination, test reliability, and concurrent validity were not observed. (Author/BW)
