Virtual presence describes a users' perception of a virtual reality (VR) environment (VRE), specifically, of their "involvement" (sense of control within a virtual environment with minimal distractions) and "immersion" (multi-input sensory engagement providing apparent realism of objects and interactions). In education, virtual…

Computer simulations have been used very effectively for many years in the teaching of science but the focus has been on cognitive development. This study, however, is an investigation into the possibility that a student's experimental skills in the real-world environment can be judged via the undertaking of a suitably chosen computer simulation…

The purpose of this study was to investigate the effects of a Computer-Assisted Instruction designed according to 7E model of constructivist learning(CAI7E) related to "electrostatic'' topic on physics student teachers' cognitive development, misconceptions, self-efficacy perceptions and attitudes. The study was conducted in 2006-2007…

Reports the design of the "Mechanics Baseline Test," an instrument to assess students' understandings about concepts in mechanics. Discusses how comparisons of test results with extensive baseline data can be used to evaluate instruction at all levels. Includes a copy of the instrument. (MDH)

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'…

Conceptual change teaching is an instructional method that helps students modify, extend, or exchange their alternative conceptions for the appropriate scientific conceptions. Provides activities and a diagnostic test to apply the method to the concepts of heat and temperature. (MDH)

This report documents a program for improving science knowledge, attitudes, and higher order thinking skills through experiential science. The hands-on approach used successfully in the program is described, and evidence of student improvement is also presented. The targeted population consisted of students in the first, third, and fourth grades…

Critical pedagogy, an ideology which opposes education as domination, views knowledge and learning as constructed by the student and teacher together. Its goal is personal and social emancipation and empowerment. The purposes of this paper are to (1) indicate problems in science education which can be addressed by teaching science from a critical,…

Researchers from BBN Laboratories and Lesley College (Massachusetts) have begun exploratory studies to build an understanding of the learning that occurs when middle school students interact with science-based simulations. Sixty hours of discussion among eight middle school students were videotaped as they used the simulations from the…

This report describes a project designed to expand higher order thinking skills in five primary students with disabilities in order to increase problem solving and decision making skills. The project incorporated higher order thinking skills into mathematics, science and language arts units, and implemented weekly, cooperative learning techniques…

Describes an analysis of test items used to measure the science process skills of 11-year-olds in Great Britain. Concludes that the level of cognitive demand was a reliable predictor of the difficulty of an item. (TW)

Presents a study to examine the effects of a verbal teaching strategy versus a strategy providing instruction using activities and manipulatives in four seventh grade earth science classes with students of varying cognitive abilities (n=83). Results indicate that students with more cognitive structures perform better and that using manipulatives…

When teachers possess detailed knowledge about children's thinking and problem solving, it can profoundly affect their knowledge of their students and their planning for instruction. Reported is a project designed to demonstrate the feasibility of redesigning courses for prospective teachers in mathematics and science by incorporating into the…
