Peer reviewedHackling, Mark W.; Lawrence, Jeanette A. – Journal of Research in Science Teaching, 1988
Compares experts', advanced students', and novice students' use of genetics knowledge to generate and test hypotheses while solving genetic pedigree problems. Reports that experts identified more critical cues, tested more hypotheses, were more rigorous in the falsification of alternative hypotheses, and were more flexible to their solving…

Peer reviewedBowen, Craig W. – Journal of Research in Science Teaching, 1990
Presented is an analysis of think-aloud protocols of graduate students solving several different tasks in organic chemistry. The systems used by these subjects were classified. It was reported that the methodological system was most often used. (CW)

Misconceptions, shown to be prevalent in students even at the college level, may affect the cognitive process of making predictions in biology. The purpose of this study was to: (1) identify students' misconceptions about important biological concepts; (2) identify students' cognitive behaviors associated with making predictions about these…

Peer reviewedLythcott, Jean – Journal of Chemical Education, 1990
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)

Peer reviewedSawrey, Barbara A. – Journal of Chemical Education, 1990
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)

Peer reviewedPickering, Miles – Journal of Chemical Education, 1990
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)

Peer reviewedAlick, Bonita; Atwater, Mary M. – School Science and Mathematics, 1988
Discusses problem-solving strategies and the successful strategy used to solve stoichiometric problems in general college chemistry courses. Reports that rereading problems, recalling a related concept, and reasoning deductively/inductively are the most heavily used strategies among 13 categories. (YP)
