A collaborative research study was designed to facilitate, at the local school level, a mathematics teacher's development of a "constructivist" pedagogy. This paper discusses the nature and influence of the teacher's professional beliefs on his attempts to create a classroom learning environment congruent with the principles of a constructivist…

The concept of consciousness played a central role in Vygotsky's research and theory. Unfortunately, with the advent of behaviorism, consciousness fell into disfavor. One of the major obstacles in studying consciousness is that there is no single acceptable definition of the term. Various researchers have dealt with five different aspects of…

The term "visual literacy" generally refers to the interpretation of the formal structure of film or television and carries with it the notion that the interpreter has knowledge of the use of camera angles, lighting, flashbacks, and so forth. However, many visual conventions encountered in movies or television may be interpreted even by…

This paper examines the gap between the learning potentials that computers provide and the actual impact of computer use on learning and development. It is argued that the computer's unique potential is derived in part from four basic attributes: information, symbol systems, user activities, and relations with the user. It is hypothesized that…

A follow-up study was made of cross-sectional research on the development of dichhaptic lateralization. One hundred and eighty students in grades 3, 5, 7, 9, and 11 from two school districts were tested. Participants were 9 boys and 9 girls from each grade level for each district. Subjects were at least 90 percent right-handed, as determined by…

This report presents a methodology for examining perceptual development in the arts and describes a study based on this methodology. The purpose of the study was to chart the developmental course of perceptual skills used in the arts and to investigate whether these skills generalize across art forms and aesthetic properties or whether they are…

The major objective of this study was to investigate the relationship between the perceptual preferences of elementary school children and their performance on pictorial model-based tests of selected science concepts. Perceptual preferences for size and shape did not significantly influence performance. Preference for color did appear to be…

The relationship between conceptual complexity and stimulus saliency was explored in a 3 x 4 factorial design using 144 undergraduates. Levels of complexity were represented by varying the ratio of relevant-to-irrelevant dimensions (1:3, 2:2, and 3:1). The saliency factor varied according to the discriminability between each attribute within…

This paper examines the effects of unavoidable pollutants on fetal development in humans. Inevitable pollutants such as radiation, pesticides, gases and lead found in the air, water, and food of our industrialized society are discussed as well as psychological correlates of industrialization and urbanization such as stress, increased noise levels…

The study reported in this paper traces the nature of the changes which take place as the child gradually acquires perspective-taking skills. The results indicate that at first the young child can correctly represent only the location of the object nearest another observer; later, he can correctly represent a before-behind relationship between…
