Reviews research on the purpose and effectiveness of laboratory activities. Discusses epistemology, problem solving, cooperative learning, student involvement, assessment, and teachers as researchers. (YP)

Widespread use of interpretive research in studies of teaching and learning has highlighted a number of crucial ethical and legal issues. Although these issues have always been a concern for researchers, use of small samples and detailed analyses of teaching and learning have brought previously hidden aspects of teaching and learning into the…

Determined that the majority of 299 preservice teachers did not use formal reasoning patterns when they attempted to solve a variety of problems. Results obtained for controlling variables and for proportional, probabilistic, correlational, and combinatorial reasoning are discussed with implications for middle/junior high school science teaching.…

Described are the rationale, methodology, and findings of seven case studies designed to investigate the teaching and learning strategies employed in science classes by exemplary teachers. Findings focused on management strategies, student understanding, student participation, and classroom environment. (CW)

Investigated changes that occurred in sixth- and seventh-grade teacher and student discourse when teachers endeavored to implement extended teacher wait-time in a sequence of seven lessons related to probabilistic reasoning. Results indicated that teacher wait-time increased from an average of 1.9 to 4.4 seconds during the lesson sequence. (JN)

To obtain reliable and valid measures of cognitive development in group settings, the Test of Logical Thinking, a paper-and pencil test of formal reasoning ability, was developed. It was administered to high school stuents, and alternate forms were then devised. Applications are discussed. (MNS)

Compares two high school chemistry teachers with two elementary science teachers from case studies from the Exemplary Practice in Science and Mathematics Education Project in Australia. Concludes that both pedagogical and content knowledge are important ingredients for outstanding teaching. (CW)

This paper provides a focus on the successful and positive facets of schooling from a series of case studies. The study involved 13 researchers in over 500 hours of intensive classroom observation of 20 exemplary teachers and a comparison group of non-exemplary teachers. The qualitative information was complemented by quantitative information…

Students from 15 intact classes in grades 6 and 7 (N=142) from suburban schools in Perth, Australia, were used to investigate their time on task and achievement in process-oriented lessons. One finding noted is a positive relationship between achievement and student reasoning ability and engagement in planning and collecting tasks. (JN)

Reports on a study to extend the concurrent and predictive validity of the Teacher Performance Assessment Instrument by including a sample of middle school science teachers. The validity criteria for the study involved observing student engagement and integrated process skill achievement. (TW)

Describes strategy analysis procedures which enable preservice teachers to implement science lesson segments in a manner that was consistent with strategies incorporated into science teaching models. Conformity to the model was uniformly high for phases related to preparing the learner, investigation planning, and data processing. (JN)

Described is how an elementary teacher established an environment conducive to learning in her classroom by implementing her own integrated science and mathematics curriculum. The implications for change on the county and state levels are discussed. (KR)

Large scale assessments of educational progress can be useful tools to judge the effectiveness of educational programs and assessments. This document contains papers presented at the research seminar on this topic held at the Western Australian Institute of Technology in November, 1984. It is the fifth in a series of publications of papers…

Activities and interactions of teachers and students from high school science classes of Western Australia were investigated. Fifteen teachers from two co-educational high schools (private and public) serving medium socio-economic level families in the metropolitan area of Perth participated in the study. The specific foci were: (1) the…

Learning environment research should take into account postpositivist ways of thinking to assist students and teachers to construct a more emancipatory learning environment. A critical perspective could lead to research playing a larger role in the transformation of science classroom learning environments. Presented a case study of a middle school…
