Evaluating the presence of response-shift bias in the CLASS with a two-pass survey
written by
W. Brian Lane and Ramesh Y. Adhikari
Most pre-to-post-instruction results of the Colorado Learning Attitudes about Science Survey (CLASS) indicate a decline in students' beliefs and attitudes about learning physics. However, by comparing post-instruction CLASS responses with retrospective responses, we have found that such results can be affected by response-shift bias due to students' changing self-evaluation metric. Response-shift bias has an overall negative impact on pre-to-post results. We also find that, when asked to predict their end-of-semester responses, students' predictions of their development were overall positive and were generally met. We discuss the implications of these findings for the interpretation of CLASS results and future explorations of this phenomenon.
