Freshman Biology Majors' Misconceptions about Diffusion and Osmosis.
Odom, A. Louis; Barrow, Lloyd H.
The data for this study were obtained from a sample of 117 biology majors enrolled in an introductory biology course. The Diffusion and Osmosis Diagnostic Test, composed of 12 two-tier items, was administered to the students. Among the major findings are: (1) there was no significant difference in scores of male and female students; (2) math placement was a significant variant when assessing understanding using the Diffusion and Osmosis Diagnostic Test; and (3) major misconceptions were detected in three areas: the particulate and random motion of matter, the process of diffusion, and the process of osmosis.
