This study examined the representational competence of students as they solved problems dealing with the temperature-pressure relationship for ideal gases. Seven students enrolled in a first-semester general chemistry course and two advanced undergraduate science majors participated in the study. The written work and transcripts from videotaped…

Examined the problem-solving performances of novices (11 undergraduates) and experts (9 graduate students and instructors), comparing them in terms of background expertise and problem-solving success. Also examined problem-solving behaviors reported in other domains and determined whether or not genetics is a fruitful area for problem-solving…

Chemists have bemoaned for years their students' inability to solve problems in introductory chemistry courses. However, at least part of this inability must be attributed to the fact that chemists have historically tried to teach their students to solve problems by doing nothing more than working examples. In recent years, chemists have begun to…

Describes the Whimbey-Lochhead approach to help students develop problem-solving skills, providing instructions for using the approach in instructional programs. Includes a list of 70 tactics or heuristics used (or misused) in problem solving. Other ideas and information from books and articles on problem solving are included. (JN)

A problem-solving method of teaching was used in the recitation sections of a freshmen chemistry course for science and engineering majors at Purdue University. The method was based on prior research which revealed that good problem solvers formed better representations and used heuristics more often than poor problem solvers. Consequently, the…

Describes a preliminary definition of engineering method as well as a definition and examples of engineering heuristics. After discussing some alternative definitions of the engineering method, a simplified definition of the engineering method is suggested. (YP)

Investigated methods science and nonscience majors use to make predictions about five situations involving the conservation of mechanical energy. Two findings, among others, show that subjects did not employ identifiable strategies in over 97 percent of the cases and show differences in the way majors and nonmajors worked the problems given.…

Proposes that there is a universal method for all realms of knowledge. Reviews Descartes's definition of the universal method, the engineering definition, and the philosophical basis for the universal method. Contends that the engineering method best represents the universal method. (ML)

Presents a case study analysis which attempts to illuminate the difference between knowledge accumulation and ability to deal with problem solving in stoichiometry. Competence is presented as ability to properly represent, solve, and verify solutions. Discusses rule or algorithm based vs. heuristic based problem solving. (JM)

Summarizes research that contrasts the approaches and attitudes of successful and unsuccessful problem solvers. Supplies a categorized list of problem solver characteristics. (RT)

Considers research concentrating on the correlation between knowledge structure and learning. Suggests implications of this research to classroom teaching. Cites characteristics of unsuccessful and successful problem solvers. (RT)

Examines some of the assumptions associated with attempts to define the "engineering method." Critiques a previously stated definition of this method, and offers an alternative definition that attempts to include the ideas put forth in the previous definition. Discusses the use of engineering heuristics in both definitions. (TW)

Describes teaching strategies that help students improve problem solving skills. Lists three factors good problem solvers were found to possess. Gives step by step instructions for solving problems. (MVL)

Examines various types of problems that researchers have used to demonstrate problem solving. Focuses on genetics problems. Discusses classes of learning outcomes, conceptual knowledge gains, content-independent heuristics, content-specific procedures, understanding the nature of science and a typology of genetics problems. (CW)

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)
