This investigation examined the relationship between problem solving ability and the criteria used to decide whether two classical mechanics problems could be solved similarly. The investigators began by comparing experts and novices on a similarity judgment task and found that experts predominantly relied on the problems' deep structure in…

Reviewed are findings on misconceptions in mechanics and their instructional implications. Many misconceptions are widespread and resistant to change but students have useful intuitions and reasoning processes that could be used more fully. One strategy for dealing with misconceptions is described. It stresses anchoring intuitions, analogical…

Describes a self-paced, learning-for-mastery course in undergraduate fluid mechanics. Includes the method of course assessment, method of student evaluation, and a description of the instructor's role and work load. Summarizes aspects of self-paced instruction considered favorable and unfavorable. (GS)

A prescriptive model of problem-solving performance is described. The aim of the model is to specify explicitly how problems should be described initially in such a form as to facilitate their subsequent solution. According to the model, the process of initial problem description can be decomposed into two successive stages. The first uses general…

This study examined a proposed procedure for constructing theoretical descriptions of mechanics problems, in particular, to determine if the procedure led to explicit and correct descriptions of the motion and interaction of systems and if the resulting theoretical descriptions facilitated generation of correct constraint equations and, hence,…

This student text and laboratory manual is designed primarily for the non-college bound high school student. It can be adapted, however, to a wide range of abilities. It begins with an examination of the properties of nuclear radiation, develops an understanding of the fundamentals of nucleonics, and ends with an investigation of careers in areas…

Teaching procedures of Project Physics Unit 6 are presented to help teachers make effective use of learning materials. Unit contents are discussed in connection with teaching aid lists, multi-media schedules, schedule blocks, and resource charts. Brief summaries are made for transparencies, 16mm films, and reader articles. Included is information…

This monograph presents an autoinstructional program in the physical sciences. It is considered useful at the higher, middle and lower high school levels. Three behavioral objectives are listed and a time allotment of 35-40 minutes is suggested. A bibliography is included. A script, incorporating the use of a cassette player and slides, is used by…

Basic concepts of nuclear structures, radiation, nuclear reactions, and health physics are presented in this text, prepared for naval officers. Applications to the area of nuclear power are described in connection with pressurized water reactors, experimental boiling water reactors, homogeneous reactor experiments, and experimental breeder…

As one of three audiovisual media in the U. S. Naval Academy Self-Paced Physics Course, 16 cassette tapes relating to lectures of mechanics, electricity, and magnetism are prepared for enriching and supplementary purposes. The material is designed to be used in combination with the talking book where illustrations, formulas, behavioral objectives,…

An experiment on sound waves, developed for non-science majors in a college physics course, is described. The student investigates the interference of two sound waves and measures and wavelength as he uses a prerecorded tape and a cassette player. The student is tutored by the cassette tape recorder, which also produces the overlapping sound…

Describes how one could teach velocity and acceleration from a Piagetian framework. This approach is compared with the traditional method of teaching constantly accelerated motion to high school and college students. Some problems and a list of references are also presented. (HM)

Gives a new definition for the concept of the elementary particle in nuclear physics. Explains why the existance of the quark as an elementary particle could be an accepted fact even though it lacks what traditionally identifies a particle. Compares this with the development which took place during the discovery of the neutrino in the early…
