The major task in solving a physics problem is to construct an appropriate model of the problem in terms of physical principles. The functions performed by such a model, the information which needs to be represented, and the knowledge used in selecting and instantiating an appropriate model are discussed. An example of a model for a mechanics…

Describes a lesson that utilized inquiry to teach the students a scientific concept and to emphasize the fact that they shouldn't jump to conclusions. (LS)

Incorporates some ideas from a book by Galileo into a problem-solving format that challenges students. (LS)

Suggests that teachers encourage student participation and self-evaluation by having the students follow a learning contract. (LS)

Studied was the performance of four Piagetian tests for formal reasoning by students between the ages of 9 and 15. Concluded that boys performed better than girls. (MLH)

Describes a non-credit tutorial course held for engineering students to improve their skill in problem solving. In the group sessions, each student writes his approach to a given problem on a transparency; the class then analyzes the various approaches while viewing them on overhead projectors. (MLH)

Twenty-two tenth grade biology classes performed a simulated problem solving game. Half of each class completed the exercise first as individuals and then in small groups; the other half reversed this order. Results showed that group work preceded by individual work was the most effective arrangement. (MLH)

Outlines the use of computer programs in modeling and simulation to provide a link between science and mathematics education. (GS)

Describes an approach which integrates experiential learning with the study of subject matter. The foundation of this program is a systems design called SAM, Self-Actualized Model. Presents design details of the program and an initial evaluation. (GS)

This project addressed the question: What knowledge and processes enable individuals to construct and modify representations of novel, nonroutine problems? The theoretical goal was to extend the information-processing theory of problem solving to include processes that have been characterized as restructuring of problems and productive thinking by…

This information sheet examines three areas: (1) what research tells about problem-solving in chemistry; (2) why students have such difficulty in solving chemistry problems; and (3) if there are some ways of teaching students to solve problems that are more effective than others. From several research studies on problem-solving in chemistry, it is…

Described is an approach to assessment of intuitive and analytic modes of thinking in physics. These modes of thinking are associated with Ausubel's theory of learning. High ability in either intuitive or analytic thinking was associated with success in college physics, with high learning efficiency following a pattern expected on the basis of…

Mammo I and Mammo II are two versions of a computer simulation based upon scientific problems surrounding the finds of carcasses of the Wooly Mammoth in Siberia. The simulation program consists of two parts: the data base and program logic. The purpose of the data pieces is to provide data of an informative nature and to enable problem solvers to…
