Julie C. Libarkin November 2001 Journal of Geoscience Education v49 n5 p435-442
This article in the Journal of Geoscience Education provides information about a study that used a Likert-scale instrument to determine the effectiveness of science courses for non-majors. Results from 991 students permitted a statistical analysis of this instrument's validity and reliability. Examples from two courses, one laboratory-based and the other grounded in collaborative learning, are provided to demonstrate the utility of these types of scales in assessing both prior knowledge and course outcomes.
