Cognitive Restructuring as an Early Stage in Problem Solving.
Peer reviewed Peer reviewed
Bodner, George M.; McMillen, Theresa L. B. – Journal of Research in Science Teaching, 1986
Examines the hypothesis that there are preliminary stages in problem solving that are often neglected in teaching chemistry. Discusses correlations calculated between the student's ability to handle disembedding and cognitive restructuring tasks in the spatial domain and ability to solve chemistry problems. (TW)

Cognitive Strategies Used by Chemistry Students to Solve Volumetric Analysis Problems.
Peer reviewed Peer reviewed
Anamuah-Mensah, J. – Journal of Research in Science Teaching, 1986
Describes an investigation of the strategies used by 47 high school students in solving volumetric analysis problems in chemistry. Reports that students in the high ability group mainly used the "formula" approach, while those in the low ability group tended to use the "proportional" approach to problem solving. (TW)
