Tests the hypothesis that two general developmentally-based levels of hypothesis-testing skills exist. Finds a positive relationship between level of hypothesis-testing skill and performance on a transfer problem involving the test of a hypothesis based on unobservable entities. Also finds a positive relationship between level of…

Contends that science education researchers should devote more time to creating and studying models of intergenerational and community-based science education. Argues that such inquiries have the potential to provoke new thinking that could expand basic conceptions of what it means to learn and practice science. (WRM)

Explores the differences between deep and surface approaches to learning science. Findings indicate that the deep-surface learning differences fall into five categories: (1) generative thinking; (2) nature of explanations; (3) asking questions; (4) metacognitive activity; and (5) approach to tasks. Suggests that teachers can encourage a deep…

Examines the relationships and development of communities of concepts related to heat and convection among fifth grade students. Discusses the influence of familial and cultural experiences on conceptual development as well as the extent to which competing phenomena affect the development of new conceptual understandings. (Contains 49 references.)…

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…

Describes researcher and teacher-researcher analyses of inquiry teaching of the nature of science to prospective elementary teachers. Discusses the difficulties with presenting a cogent and comprehensive picture of the nature of science, the teacher's pivotal role in initiating discussions of science and scientists' work, and the strengths and…

Investigates the effects of instruction and achievement on science question level for high and low science topic interests. Finds that students who received instruction in researchable questioning outperformed those who were not instructed, and that high achievers in mathematics, reading, or science outperformed low achievers. (Contains 41…

Examines primary teachers' confidence and identity as science teachers in tandem with their views on the British National Curriculum and the warrants they give for those views. Collects data using in-depth interviews with a small sample of primary teachers, setting their views in the context of their science-related life stories. (Contains 28…

Assesses the influence of three history of science (HOS) courses on college students' and preservice teachers' conceptions of nature of science (NOS). Examines whether participants who entered the investigated courses with a conceptual framework consistent with contemporary NOS views achieved more elaborate NOS understandings. Explores the aspects…

Contributes to the growing body of knowledge about students' conceptions and views of environmental and natural resource issues. Questions 9th and 12th grade Swedish students' understandings of the greenhouse effect, reduction of CO2 emissions, and the depletion of the ozone layer. Observes five models of the greenhouse effect that appear among…

Explores the relationships among science and engineering attitudes, physics conceptual understanding, and physics achievement for a population of college freshman engineering students. Assesses a sample of freshman engineering students (n=200) participating in an integrated curriculum with the Force Concepts Inventory (FCI), Mechanics Baseline…

Assesses the potential of multimedia authoring as a learning tool using the software ASTOUND. Investigates the knowledge acquisition caused by a multimedia program among 32 grade 12 students on a multi-disciplinary environmental unit about earthquakes. Provides basic background about earthquakes via laboratory experiments and field trips to…

Explores the science content knowledge of elementary school teachers and its possible role in helping them teach effectively. Studies the issues in the context of an investigation of the views of elementary school teachers (n=106) who had participated in professional development courses that focused on the topic "natural and processed materials".…

Tests the hypothesis that maturing prefrontal lobes play a role in the development of proportional reasoning skill because the prefrontal lobes are involved in the inhibition of task-irrelevant information and the representation of task-irrelevant information. Assigns students randomly to manipulative or verbal tutoring groups and tests both…

Observes 16 students from five elementary science classes to examine how students use tools when constructing new knowledge during science instruction, how control of tools is actualized from pedagogical perspectives, how language and tool accessibility intersect, how gender intersects with tool use, and how competition for resources impacts…
