Abstract

This article describes the development of a ten-item scale to assess biology majors' self-efficacy towards the critical thinking and data analysis skills taught in an upper-division cell biology course. The original seven-item scale was expanded to include three additional items based on the results of item analysis. Evidence of reliability and validity was collected and reported for the revised scale. In addition, the effect of varying the number of response categories presented with the items was empirically examined by administering different versions of the instrument containing 6, 11,21, and 101 response categories to randomly selected samples of students in the course. Rasch scaling procedures were used to analyze the results. (PsycINFO Database Record (c) 2012 APA, all rights reserved). (journal abstract)
