To determine whether practice was consistent with recommended research methods, this study examined 130 studies reported over a 5-year period in the "Journal of Research in Science Teaching." Results show that appropriate generalizations beyond the confines of the reported studies may be impossible in most (64%) of the studies.…

Describes an exploratory study to identify determinants of elementary student's intentions to perform laboratory and nonlaboratory science activities. Fishbein and Ajzen's theory of reasoned action was used as the basis for the study. (PR)

Reports a naturalistic study to develop and validate a "Science and Reading Questionnaire" to assess secondary science teachers' attitudes toward science reading and their belief or informed opinions about science reading. The items for this instrument are presented. (PR)

Mixed methods research conducted across three semesters in introductory college geology classes (n=187, 190, 138) attempted to ascertain whether integrated study of petrified wood could serve as a portal to improved student geobiological understanding of fossilization, geologic time, and evolution. The Petrified Wood Survey[TM] was administered as…

Investigates the relationship of locus-of-control orientation and task structure to the science problem-solving performance of 100 same-sex, sixth-grade student pairs. Some overall conclusions were that there was no relationship between locus-of-control orientation and effectiveness of problem-solving strategy. Internality was significantly…

Test-wiseness strategies used by 11 general chemistry students as they answered a 15-item multiple choice examination were investigated using a think-aloud technique. The most common strategies were those that did not compromise the validity of the examination: error avoidance, elimination of incorrect responses, checking responses, and optimal…

This project consisted of a meta-analysis of U.S. research published from 1980 to 2004 on the effect of specific science teaching strategies on student achievement. The six phases of the project included study acquisition, study coding, determination of intercoder objectivity, establishing criteria for inclusion of studies, computation of effect…

Evaluated the effects of cooperative learning on students' (n=36) verbal interaction patterns and achievement in a conceptual change instructional model in secondary science. It was found that students using cooperative-learning strategies showed greater achievement gains and made greater use of specific verbal patterns believed to be related to…

Interviews were conducted with grade 10 students (n=34) who had received 4 years of physics instruction. Interview's focus was to understand students' responses from their point of view. The results of the study confirm and deepen findings from other studies concerning students' severe difficulties in learning the energy concept, the particle…

This study investigated whether Science Curriculum Improvement Study or more recent interpretations of the learning cycle could be used by teachers to engage students in social constructivist learning. Two researchers and six science teachers implemented instruction based on the reciprocal use of language and action. Changing beliefs and practices…

Reports on misconceptions held by intermediate grade students concerning chemistry textbook concepts, on the relation of reasoning ability to those misconceptions, and on the extent that textbooks encourage misconceptions. Concludes that the level of understanding displayed for the selected concepts, in combination with the nature of students'…

Presents results of intensive clinical interviews with 11 high school chemistry students representing a broad range of achievement levels as selected from 180 students who completed a written test upon completion of an instructional unit on chemical change. Results indicate that students commonly experience difficulties in chemical knowledge,…
