Authors describe some alternative conceptions held by Portuguese physics students about mechanics and compare students' scientific conceptions with the evolution of historical ideas. Authors contend that teacher knowledge about the history of science can facilitate teaching for conceptual change in physics. (over 20 references) (Authors/PR)

Proposes an adaptation of a television game show as a method to review at the end of a unit or semester. Describes procedures to conduct the game. (MDH)

Two different methods of measuring the temperature of an incandescent lamp at various voltage levels are described. By observing the color produced at a particular voltage levels, the lamp's color as a function of temperature can be determined. Needed equipment include a variac, a voltmeter, and an ammeter. (KR)

Evaluates the technical efficacy of the V-Scope in measuring motion produced by a phonograph turntable, a template furnished by the manufacturer, a free-fall apparatus, some pendula, a gyroscope, and three air tables. Concludes that the V-Scope gives excellent results and is easy to use. (MDH)

The author asserts that the benefits of animal dissection can be experienced by dissecting electronic devices. Students can dissect an electrical device and write a lab report which includes detailed descriptions, drawings, and sometimes electrical components mounted on a display board. The electronic devices for this activity are brought from…

Various modes of reflection are classified and practical examples of devices, such as cat's eyes, are discussed. Typical light rays are traced through several systems, providing exercises with varying degrees of difficulty. Corner-cube retroreflectors, glass spheres, reflecting luminaries, light concentrators, parabolic reflectors, and off-set and…

Outlines the highlights of experiments that allow students to trace the historical development of our understandings of cosmic rays. The experiments provide for two outdoor fieldwork experiences, indoor laboratory work, and an opportunity for a group of students to show originality and initiative. (ZWH)

Provides insights regarding women students in physics. Also discusses how an external organization, the American Physical Society, acted as a catalyst for enhancing science education for women. (ZWH)

Describes a preliminary survey of the views held by second-year sixth form students (n=421) on a range of subjects at A level and degree level, with a particular focus on mathematics and physics. (ZWH)

Examines the following hypotheses: (1) a relationship exists between school achievement and success in first year university physics; (2) tertiary success is a function of the motivation and metacognitive strategies of the learners; and (3) a weighted combination of indicators will allow significant discrimination between levels of tertiary…

Focuses on the work of one experienced physics teacher and his attempts to come to grips with a new curriculum. This study confirms that change is not a linear process but is characterized by uncertainty, hesitancy, and gradualism. Strategies to help others change are provided. (ZWH)

A study involving 42 students enrolled in a physics course was conducted to document students' epistemologies and their concurrent views about knowing and learning. Analyses revealed a spectrum of epistemological commitments commensurable with positions from objectivism to relativism. Implications to classroom environment are discussed. (ZWH)

Describes a study designed to identify the various reasoning procedures used by students (n=229) in comparing the average velocities of two moving bodies; compare the differences among the procedures used by students at different school levels; and analyze the relationship between automatic and human diagnoses to identify diagnostic errors of the…

Discussed is the search for life on other planets similar to Earth based on the Drake equation. Described are search strategies and microwave searches. The reasons why people are searching are also discussed. (KR)

Discussed is the physics that underpins Schuster's technique for obtaining a parallel light beam for use in various prism and grating experiments. Basic physics concepts using geometrical optics of prism, together with elementary differential calculus are explained as well as the mechanics of Schuster's technique. (KR)
