Examines the teaching of science and technology in a new curriculum in the last year of high school in Victoria, Australia. Physics and chemistry were linked to the study of materials and technology. The area of materials related all three subjects but enrollments were much higher for physics and chemistry than for materials and technology. (AIM)

Proposes that more cost-effective physics teaching could be achieved if methods of teaching and learning were substantially revised from the point of view of the desired objectives and if teachers recognized the need for continuing professional development in this area. Also recommends more student self-assessment, both as an economical measure…

Describes an ammeter that can be built for less than a dollar with commonly available parts to be used in circuits with 3-volt light bulbs. (WRM)

Argues for innovation in teaching physics. Contends that the major premise of work in physics education is that educational innovations should be based on research into student learning, and that the effectiveness of an innovation should be evaluated by openly assessing what students have actually learned--a notion that is starling to those in…

Explains the scientific concepts, technical designs, and materials that make up incandescent light sources. (WRM)

Describes and explains a procedure for photographing the chaotic scattering of light. (WRM)

Identifies middle school and college students' prior ideas about electrostatic induction. Presented students with observational evidence that supported or refuted their own prior ideas in an interview format. Concludes that the Lakatosian rather than the Popperian view is more acceptable in understanding students' responses to conflicting…

The main goal of most physics textbooks is to develop declarative and procedural knowledge. Exercises provide pupils with opportunities to apply this knowledge. However, when confronted with more complicated exercises many pupils experience difficulties in solving them. A computer program about the subject of forces was developed containing hints…

This investigation explores the kinds of study strategies used by campus-based university students in terms of the dialogues they engaged in while learning physics and chemistry in both large and small classes. Research objectives were threefold: (1) to document what dialogue types, mediated through which resources, were generally utilized by…

In this article, the author shares a very successful 50-minute inquiry-based physics lesson that uses only small metal cans, a bit of string, and the inquiring minds of middle schoolers. The topic of the lesson is wave motion and energy transfer. The intent of this article is to show that tests of student-generated hypotheses can be simple, quick,…

Nanoscience refers to the fundamental study of scientific phenomena, which occur at the nanoscale--nanotechnology to the exploitation of novel properties and functions of materials in the sub-100 nm size range. One of the underlying principles of science is development of models of observed phenomena. In biology, the Hardy-Weinberg principle is a…

In this study, the effects of different types of support for learning from multiple representations in a simulation-based learning environment were examined. The study extends known research by examining the use of dynamic representations instead of static representations and it examines the role of the complexity of the domain and the learning…

This study investigates factors affecting the degree of novice physics students application of the naive impetus theory. Six hundred and fourteen first-year university engineering physics students answered the Force Concept Inventory as a pre-test for their calculus-based course. We examined the degree to which students consistently applied the…

Plant tropisms--their directional movement in response to stimuli--are a fundamental concept in plant science and excite students because they are the observable signs of life in plants. Unfortunately, the precollege teaching literature is full of tropism misconceptions. An inexpensive clock clinostat is invaluable for student gravitropism and…

Recently, the importance of an everyday context in physics learning, teaching, and problem-solving has been emphasized. However, do students or physics educators really want to learn or teach physics problem-solving in an everyday context? Are there not any obstructive factors to be considered in solving the everyday context physics problems? To…
