Research in chemistry education has revealed that students going through their undergraduate and graduate studies in organic chemistry have a fragmented conceptual knowledge of the subject. Rote memorization, rule-based reasoning, and heuristic strategies seem to strongly influence students' performances. There appears to be a gap between what we…

Subcellular processes like meiosis are frequently problematic for learners because they are complex and, except for the extent that they can be observed under a light microscope, occur outside of our direct experience. More detailed characterization of what underlies various degrees of student understanding of a process is required to more fully…

Reported is a study designed to improve problem-solving skills of high school chemistry students. Interpretations of the data are presented. Recommendations for improvement in teaching problem solving in chemistry are proposed. (CW)

Compared in this research was the performance of students on numerical versus conceptual chemistry problems at the introductory college level. Separate analyses were done to compare high and low achievers. It was shown that even the upper group of achievers had difficulty with concept questions. (CW)

Analyzed was the performance of students on numerical versus conceptual chemistry problems in their freshman general chemistry course and their sophomore organic chemistry course. Data indicated that the ability to solve a problem did not necessarily imply an understanding of the concepts involved. (CW)
