Presents a diagnostic test for measuring college biology students' understanding of diffusion. Three general steps were used: (1) defining the content boundaries; (2) collecting information on students' misconceptions; and (3) instrument development. The split half reliability was 0.74, difficulty indices ranged from 0.23 to 0.95, and the discrimination indices ranged from 0.21 to 0.65. (ZWH)
