Some descriptions of learning represent the process as the development of organisations of elements. Various organisations have been proposed, for example, schemata and conceptual structures. Such representations assume that mental entities, such as concepts, are sufficiently stable and differentiated to be treated as units. We discuss these…

The simple task of bouncing a ball on a racket offers a model system for studying how human actors exploit the physics and information of the environment to control their behavior. Previous work shows that people take advantage of a passively stable solution for ball bouncing but can also use perceptual information to actively stabilize bouncing.…

In a series of 3 experiments modeled after infant studies, 3- to- 6-year-old children's intuitive knowledge about support was assessed. Different objects were shown either sufficiently supported or not. Children had to predict whether a block would remain standing on a platform upon release or make perceptual judgments about the possibility of a…

The research outlined in this paper investigated how student teachers perceived the development of their knowledge and attitudes towards physics through video recorded practical workshops based on experiments and subsequent group discussions. During an 8-week physics course, 40 primary science student teachers worked in groups of 13-14 on…

Consonance and dissonance are subjective perceptions that are reactions of the human ear to whether or not musical intervals sound "pleasing." The physical causes of consonance and dissonance are not as well understood as other subjective properties of sound perceived by the ear such as pitch, loudness, and quality (timbre). What follows is an…

Directions are given for student learning activities on illusions, shadows, the spectrum, and colors. (DT)

Compares between the component and the modules (system) approaches which are used to teach electronics at Croydon High School, Australia. The author presents some personal views from his experience of teaching both ways. (HM)

An experimental course for the study of acoustics is taught at Hampshire College for students interested in the interface of physics and music. This paper outlines the course, describes the basic techniques it employs, gives examples of successful exercises, and discusses some difficulties not yet overcome. Computers are heavily utilized, removing…
