The purpose of this study was to evaluate the psychometric properties of the Materials Concept Inventory (MCI) and then recommend revisions. The MCI was administered to a sample of 303 undergraduate engineering students enrolled in a materials engineering course taught by an instructor unrelated to this study. The MCI demonstrated adequate reliability (Cronbach's alpha was .73) and strong discriminatory power (Ferguson's delta was 0.96). A pretest MCI was given only two days into the course and was able to predict the final course grade (r = .30, pFinally, they wanted to show that traditional general chemistry courses show little improvement in student understanding overtime (Mulford and Robinson, 2002).
