This study examined 7th‐grade life science students, 10th‐grade biology students, and college zoology students for understanding of the concept of diffusion. Responses from 100 students from each grade level were randomly selected for data analysis. Each student responded to a test packet consisting of a biographical questionnaire, two Piagetian‐like developmental tasks, and a Concept Evaluation Statement (CES). The CESs were used to measure the students' understandings of the concept of diffusion. None of the 300 students across the three grade levels exhibited complete understanding of the diffusion concept. There was no appreciable difference among the grade levels in sound or partial understanding, misconceptions, or “no understanding.” An analysis of the misconceptions exhibited by the college sample showed that many of the misconceptions could be traced to a misapplication of scientific terminology.
