In this study, the intuitive physics of free fall was explored using Information Integration Theory and Functional Measurement. The participants had to rate the speed of objects differing in mass and height of release at the end of an imagined free fall. According to physics, falling speed increases with height of release but it is substantially…

This article summarizes the major components of curriculum design: vision, operationalization of the vision, design, and evaluation. It stresses that the relationship between these components is dynamic, and that the process of curriculum design does not proceed via a linear application of these components. The article then summarizes some of the…

This paper is focused on primary trainee teachers' conceptualization of the vision process and image formation in a plane mirror. The study involved 55 non-specialist, undergraduate trainee primary teachers on a 4-year programme of initial teacher training. The process incorporated tracking trainees' ideas during university-taught sessions through…

Describes construction and use of a simple home-built device, using an overhead projector, for use in demonstrations of the addition of various combinations of red, green, and blue light. Useful in connection with discussions of color, color vision, or color television. (JRH)

This study examines the relationship between student misconceptions and learning by focusing on six fifth-grade students as they attempt to make sense of classroom instruction on light and seeing. Pretests, posttests, and classroom observation narratives served as student data. Pretests indicate that students held the misconception that sight is…

Explores high school students' and preservice teachers' knowledge of light, vision, and related topics before and after commonly practiced instruction. Suggests a hierarchical structure to represent the collective conceptual knowledge of students and teachers in terms of facets and schemes of knowledge. Makes suggestions for designing instruction…

This guide to providing educational services to students with visual impairment is intended for use by educators in either mainstreamed or specialized settings and encourages the use of a broad spectrum of service options in both rural and urban areas of Wisconsin. The guide first presents information on the detection, referral, and assessment…
