Findings from physics education research strongly point to the critical need for teachers' use of multiple representations in their instructional practices such as pictures, diagrams, written explanations, and mathematical expressions to enhance students' problem-solving ability. In this study, we explored use of problem-solving tasks for…

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…

This article examines the process of shifting to a "Physics First" sequence in science course offerings in three school districts in the United States. This curricular sequence reverses the more common U.S. high school sequence of biology/chemistry/physics, and has gained substantial support in the physics education community over the…

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.…

Presents an activity in which students work in cooperative groups and roll balls down inclined planes, collect data with the help of an electronic motion detector, and represent data with a graphing calculator to explore concepts such as mass, gravity, velocity, and acceleration. (Contains 12 references.) (Author/ASK)

Explores the new proving of Ceva and Menelaus's results from Archimedes's Law of the Lever. Presents the geometrical construction of the weighted centroid of the gravity of finite particles along with some properties of vector representation, and sets up a related result to spatial shape. (Author/ASK)

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…

Examines the relationship of the amount of available short-term memory with the complexity of tasks the subjects mastered. Presents some hints for a better design of instruction. (YP)

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)

Two studies examined the construction of children's beliefs about projectile motion of a ball rolled off a table. Describes the concepts used by children, analyzes their use as a function of age, and gives a naturalistic description of their use. Results indicate that appropriate instruction can remediate misconceptions. (MDH)

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…

Twenty three at-risk high school female students who had failed mathematics and science in a traditional school setting were the subjects of this study that integrated mathematics and science lessons over a period of four weeks. Using a combination of direct instruction, calculations, graphing, hands-on projects, and discussion, the topic of…

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.)…
