Examines the effects of open inquiry instruction on low achieving, marginalized high school students. Involves students with long histories of scholastic failure in question generation, experimental design, and argument construction as part of their General Science course instruction. Compares students' entrance and exit interview responses which…

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…

Explores the use of an impact evaluation model across time and clientele groups that is used to evaluate exhibits from two science centers in Manila. Questionnaire and interview data indicate that students prefer exhibits that produce sound, light, and motion. (DDR)

Measures both teaching efficacy and the holding of specific alternative conceptions of preservice elementary teachers (N=619). Uses a survey to determine the relationship between teaching efficacy and certain alternative conceptions. Contains 77 references. (DDR)

Investigates high school students' knowledge of natural phenomena related to the concept of light flux as it applies to the seasons and illumination after they studied optics. Discusses didactic, cognitive, and ontological perspectives in relation to specific changes in the science curriculum. Contains 71 references. (DDR)

Explores the perspectives of two high school science teachers on teaching for conceptual change as they work with graduate level preservice teachers. Details the conceptual change model employed by the teachers. (DDR)

Proposes a socioconstructivist environmental education. Explains that the challenge of environmental education is to enable students to gain a more complex representation of the sciences. Contains 35 references. (DDR)

Discusses the basic features and goals of environmental education incorporated into curricula in Slovenia. Findings suggest that waste-processing products are not well known and that Slovene children should be taught about environmental problems that are part of everyday life. (DDR)

Discusses the structure of a laboratory course that employs guided inquiry and collaborative learning to increase student preparedness for and intellectual engagement in laboratory investigations, and to give students an understanding and appreciation of a collaborative work environment. Contains 29 references. (DDR)

Presents a study in which the conversations of primary school groups were collected in a botanical garden and analyzed for content. The data were examined for the effects of the presence or absence of an adult in the group, age, and the sex of the pupils. (Contains 27 references.) (Author/DDR)

Outlines an alternative atomic model to the probability model, the descriptive quantum atomic model Electronium. Discusses the way in which it is intended to support students in learning quantum-mechanical concepts. (Author/MM)

Does a sensori-motor experience help a physics student understand the movement of molecules in solids, liquids, and gases? Students aged 9-10 were given either traditional demonstrations of solids, liquids, and gases and the variation of molecular motion with temperature (iconic presentation), or they were involved in physical activities as they…

Investigates not only the influence but also the confluence of students' and teacher's understandings of the quality of whole class discussions. Focuses on the communication between students and the teacher in the classroom. Considers the role of tools in both supporting and constraining communication in the classroom. (Author/MM)

Describes an epistemological framework and an associated research method. The framework focuses on the structural relations of individual and setting as experienced by the individual. The analysis consists in zooming to identify patterns that simultaneously occur at multiple levels. Uses data from a physics classroom where students learn to…

Argues that evolution is a process that occurs within the curriculum as well as within the physical universe. Provides an example that involves student presentations. Discusses the transition from poster presentations to electronic presentations via the World Wide Web. (DDR)
