Interviewing is widely used in the initial exploration of domain expertise. Work and cognitive task analysis chart the knowledge,…

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)
