Olson, Joanne K.; Bruxvoort, Crystal N.; Vande Haar, Andrea J. – Journal of Research in Science Teaching, 2016
Little is known about how the content of a video case influences what preservice teachers learn about science teaching. This study was designed to determine the impact of two different video cases on preservice elementary teachers' conceptions of multiple aspects of effective science teaching, with one video selected to focus attention on the role…

Schroeder, Carolyn M.; Scott, Timothy P.; Tolson, Homer; Huang, Tse-Yang; Lee, Yi-Hsuan – Journal of Research in Science Teaching, 2007
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…

Clary, Renee M.; Wandersee, James H. – Journal of Research in Science Teaching, 2007
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…

Lonning, Robert A. – Journal of Research in Science Teaching, 1993
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…

Voska, Kirk W.; Heikkinen, Henry W. – Journal of Research in Science Teaching, 2000
Identifies and quantifies the chemistry conceptions used by students when solving chemical equilibrium problems requiring application of LeChatelier's Principle, and explores the feasibility of designing a paper and pencil test to accomplish these purposes. Eleven prevalent incorrect student conceptions about chemical equilibrium were identified…
