Before we can effectively apply specific interventions through professional development, it is important to determine what is occurring in our high school physics classrooms. This study investigated common professional practices in physics teaching among a representative sample group of schools and teachers from a diverse, geographically large…

Research has indicated that experts' subject matter knowledge structures (SMKSs) differ from those of novices in that they contain more cross-linking, interconnections, and overarching thematic elements, characteristics that are in accordance with those espoused in current reform documents. Unfortunately, teachers' SMKSs are not…

Analogies are known to foster concept learning, whereas discovery learning is effective for transfer. By combining discovery learning and analogies or similarities of concepts, attractive new arrangements emerge, but do they maintain both concept and transfer effects? Unfortunately, there is a lack of data confirming such combined effectiveness.…

Suggests an instructional presentation designed to give students an intuitive understanding of the uniform acceleration of a body falling toward the earth. (JR)

The effects of bridging analogies teaching strategy and gender on Turkish high school students' misconceptions in mechanics were investigated. After a pilot study with 67 students in a nearby high school, the researchers' administered the revised Mechanics Misconception Test to 119 high school students as a pretest. Students in the experimental…

Provided is a unit which relates the fulcrum of a lever system and the mean of a distribution of scores. The objective, rationale, two student laboratories, and an evaluation system are outlined. Content background on statistics is offered. (MVL)

Many years ago, Arons pointed out the incomprehension science students exhibit of the basic mathematical operations multiplication and division and the need to address the problem in physics classes to assure student understanding of the physical world. McDermott et al.'s Physics by Inquiry program does address this need directly and in detail (by…

Proposes the use of videotaped vignettes from movies, television programs, and commercials to illustrate physics concepts. Presents two examples, complete with methods of use and follow-up activities, of videotape recordings illustrating the concepts of gravity and projectile motion. Includes guidelines for use of copyrighted videocassettes and…

Uses the format of a dramatic play as a means of explaining the relativity of time to beginning physics students. (JR)

Discusses the problem of gravity as it relates to distance from the center of the earth, and reports contradictory explanations from different source books. Uses this example to illustrate that science should not be taught from a single source, such as a textbook. (JR)

Describes an instructional sequence in which a bicycle context was used to increase the status of appropriate concepts of work and simple machines. Tests this instructional sequence in an applied physics course for elementary education majors. Makes implications for conceptual change pedagogy and curriculum design. (Contains 13 references.)…

Describes the use of contract teaching with a class of competent senior students taking PSSC Physics. Explains the method used, reports the results obtained on tests in comparision with another class, and offers recommendations for teachers interested in trying this method.(JR)

Fifty subjects were physics graduate students in Taiwan, and forty-five were physics graduate students in the United States. Results indicated Taiwanese students pursuing their studies in the United States did not feel as well prepared as their counterparts. Recommendations include revision of undergraduate curriculum and requiring more English…

High school physics students (n=41) were exposed to both massed and distributed practice on two different physics topics. Results suggest that using distributed practice in high school physics classrooms can lead to higher student achievement. (11 references) (Author/MKR)
