Peel, Amanda; Sadler, Troy D.; Friedrichsen, Patricia – Journal of Research in Science Teaching, 2019
Computational thinking (CT) is a way of making sense of the natural world and problem solving with computer science concepts and skills. Although CT and science integrations have been called for in the literature, empirical investigations of such integrations are lacking. Prior work in natural selection education indicates students struggle to…

Schwendimann, Beat A.; Linn, Marcia C. – Journal of Research in Science Teaching, 2016
Concept map activities often lack a subsequent revision step that facilitates knowledge integration. This study compares two collaborative critique activities using a Knowledge Integration Map (KIM), a form of concept map. Four classes of high school biology students (n?=?81) using an online inquiry-based learning unit on evolution were assigned…

Furtak, Erin Marie – Journal of Research in Science Teaching, 2012
Learning progressions, or representations of how student ideas develop in a domain, hold promise as tools to support teachers' formative assessment practices. The ideas represented in a learning progression might help teachers to identify and make inferences about evidence collected of student thinking, necessary precursors to modifying…

Nehm, Ross H.; Ha, Minsu – Journal of Research in Science Teaching, 2011
Despite concerted efforts by science educators to understand patterns of evolutionary reasoning in science students and teachers, the vast majority of evolution education studies have failed to carefully consider or control for item feature effects in knowledge measurement. Our study explores whether robust contextualization patterns emerge within…

Beyer, Carrie J.; Delgado, Cesar; Davis, Elizabeth A.; Krajcik, Joseph – Journal of Research in Science Teaching, 2009
Reform efforts have emphasized the need to support teachers' learning about reform-oriented practices. Educative curriculum materials are one potential vehicle for promoting teacher learning about these practices. Educative curriculum materials include supports that are intended to promote both student "and" teacher learning. However, little is…

Settlage, John, Jr. – Journal of Research in Science Teaching, 1994
Explores the nature of the changes in students' explanations (n=50) of evolutionary scenarios. Teleological and Lamarckian explanations accounted for over half of the students' explanation on the pretest but dropped to less than 20% on the posttest. (ZWH)

Gallegos, Leticia; And Others – Journal of Research in Science Teaching, 1994
Examines the predator-prey relations and the preconceptions held by children (n=506) on the construction of food chains. Results show that the classification of herbivores and carnivores is based on children's preconceptions of size and ferocity and sheds light on the difficulties students have at higher education levels in the resolution of food…

Songer, Catherine J.; Mintzes, Joel J. – Journal of Research in Science Teaching, 1994
Explores and documents the frequencies of conceptual difficulties confronted by college students (n=200) seeking to understand the basic processes of cellular respiration. Findings suggest that novices harbor a wide range of conceptual difficulties that constrain their understanding of cellular respiration and many of these conceptual problems…

Lawson, Anton E.; And Others – Journal of Research in Science Teaching, 1993
The experimental/analogy group scored significantly higher than the control group on a posttest question that required the definition of diffusion (n=77 community college students). Hypothetico-deductive reasoning skill was significantly related to correct application of the diffusion concept to a change from the misapplication of the polarity and…

Lawson, Anton E. – Journal of Research in Science Teaching, 1988
Reports on a study in which clinical interviews were conducted with three elementary school children to determine the extent to which they held naive misconceptions about important biological topics, and to determine agewise trends in the development of biological knowledge. (TW)

Lawson, Anton E.; Thompson, Lois D. – Journal of Research in Science Teaching, 1988
Explores the relationships between seventh-grade students' misconceptions of genetics and natural selection and four cognitive variables: reasoning ability; mental capacity; verbal intelligence; and cognitive style. Reports that only the reasoning ability was significantly related to the number of misconceptions. (Author/YP)

Odom, Arthur Louis; Barrow, Lloyd H. – Journal of Research in Science Teaching, 1995
Presents a diagnostic test for measuring college biology students' understanding of diffusion. Three general steps were used: (1) defining the content boundaries; (2) collecting information on students' misconceptions; and (3) instrument development. The split half reliability was 0.74, difficulty indices ranged from 0.23 to 0.95, and the…

Griffiths, Alan K.; And Others – Journal of Research in Science Teaching, 1988
Investigates the remediation of misconceptions through application of Gagne's hierarchical learning theory. Uses stoichiometry, food levels, and conservation of mechanical energy as the target concepts. Reports that there was no treatment effect in analysis of covariance using pretest scores as a covariant. (YP)

Westbrook, Susan L.; Marek, Edmund A. – Journal of Research in Science Teaching, 1992
The conceptual views of homeostasis held by students (n=300) in seventh grade life science, tenth grade biology, and college zoology were examined. A biographical questionnaire, the results from two Piagetian-like developmental tasks, and a concept evaluation statement of homeostasis were collected from each student. Understanding of the concept…

Browning, Mark E.; Lehman, James D. – Journal of Research in Science Teaching, 1988
Describes a computer program presenting four genetics problems to monitor the problem solving process of college students. Identifies three main areas of difficulty: computational skills; determination of gametes; and application of previous learning to new situations. (Author/YP)
