One hundred years after its conception, the scientific method continues to reinforce a kind of cultural lore about what it means to participate in inquiry. As commonly implemented in venues ranging from middle school classrooms to undergraduate laboratories, it emphasizes the testing of predictions rather than ideas, focuses learners on material…

Discusses an experiment designed to give students a feel for the way in which theoretical models evolve. Students are given a system unknown to them and asked to develop a consistent model which fully explains all their observations on the system. (Author/GA)

A general discussion of prediction and the use of models as a means of understanding reality is provided, focusing on the application of mathematical models to various scientific disciplines and its role in experimentation. (DC)

Presented is an astronomy activity in which students use an apparatus to illustrate the various positions and movements of the sun, earth, planets, stars, and constellations. A test of the heliocentric theory of the solar system is included. (CW)

Discusses a paradigm shift from technological positivism to social systems thinking in technology. Describes the role of engineers and engineering education from the perspective of this new orientation. (YP)

A set of computer implemented models are presented which can assist in developing problem solving strategies. The three levels of expertise which are covered are beginners (those who have completed at least one university physics course), intermediates (university level physics majors in their third year of study), and professionals (university…

During the summer of 1986 a conference funded by the National Science Foundation (NSF) was organized to assess the current state of cognitive research on the psychology of physics problem solving, and to examine the needs of physics instructors and instructional designers that must be addressed by a psychological theory of physics problem solving.…
