This study addresses the measurement of high school students' epistemic knowledge associated with scientific experimentation (EKSE) which concerns "how" scientific experimentation generates knowledge and "why" that knowledge is justified. Based on philosophical, educational standards, and literature analyses, an EKSE construct…

This article takes its point of departure from the younger generation's problematic relationship with time and the future. A general sense of changeability and directionlessness in society compromises young people's confidence in themselves to make a difference as individuals in important global issues affecting their futures, such as climate…

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…

This study examined 188 preservice science teachers' professional growth along three dimensions--self-regulated learning (SRL) in a science pedagogical context, pedagogical content knowledge, and self-efficacy in teaching science--comparing four learner-centered, active-learning, peer-collaborative environments for learning to teach higher order…

Describes the contributions of the National Science Foundation (NSF) to the development of college faculty in 1958, 1968, and 1978. The described activities are NSF institutes, faculty research participation, and fellowship programs. (HM)

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…

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)

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…

The number of observations made by 3-year-old students increased following a series of science activities emphasizing observational skills. (AL)

Analyzes three approaches (physical, mental, combined practice) to improving freshman chemistry psychomotor laboratory skills. Although no significant differences were found between treatments, there were significant differences when each was compared to the control sections. Mental practice appears to offer an efficient methods for reinforcement…

Tests the applicability of Ausubel's theory to the meaningful learning of intellectual skills. Results of three studies of high school students indicate that advance organizers enhance learning of skills related to solubility product problems. This effect was removed if prior teaching in relevant background knowledge was included. (Author/WB)

This study was developed to provide advice to teachers on how to use rules in teaching experimental design in science classes. A review is presented on the use of rule in science teaching and the effects of instructional treatments are assessed on Canadian high school students' skills of experimental design. (ML)

Explains the convergent and discriminant validity of two tests of science process skills with two tests of formal reasoning ability. Reports test results from elementary education majors and discusses the tests' intercorrelations. Implications related to instruction are analyzed. (ML)
