Low teacher self-efficacy is an important factor constraining the teaching of science at the elementary level. This study was designed to investigate the effectiveness of particular sources of efficacy information for enhancing the science teaching self-efficacy of practicing elementary teachers. Twelve teachers participated in an intervention…

Investigated whether instructing children in the component skills underlying Piagetian transitivity tasks would increase their performance on both transitivity-related tasks and on reasoning tasks not directly related to transitivity. Results indicate that incorporating the quantification of certain abstract symbols, training can influence…

Reports results supporting the theoretical rationale that there are certain cognitive skills, including data interpretation, identification of assumptions and hypotheses, and controlling of variables, that appear to be necessary for successful understanding of the heterotroph hypothesis, as presented in the BSCS Blue Version. Implications for…

Investigated was the retention of the skills of observation and comparison in junior high school students in a rural junior high school and an urban setting. Data obtained showed a consistently high degree of retention for both skills (although degree of retention was higher for observation than for comparison skills) regardless of treatment…

This is a continuation of the report on a study of skill retention (observation and comparison) in junior high school students. (See SE 511 538 for additional information.) Reported in this article is an investigation to determine if the skills retained could be transferred to a new set of scientific objects. Results appeared to show that both…

Argues that the failure of modern courses to achieve their declared goals in relation to children's understanding of science has two causes, namely teachers views about the nature of science, and a degree of confusion in the philosophical stance implicit in many science curricula. Presents a philosophical model for curricula. (CW)
