Investigates the use of collaborative learning groups in a physical science course designed for elementary education majors (n=54). Data for the study were 20 video-taped laboratory sessions, the instructor's journal, and the students laboratory reports. Among the conclusions is that the collaborative science laboratories provided insightful…

Identifies factors, both helpful and obstructive, influencing teachers' transition from basal to a whole-language curriculum. Observations from two first-grade classrooms and interviews with school principals and two classroom teachers (one whole-language veteran and the other in transition into whole language) are evaluated. (GLR)

Teaching strategies associated with a conceptual change model of science teaching were examined in a study of seventh-grade life science teachers (n=13). Greater use of conceptual change teaching strategies was associated with use of the special instructional materials, not with the training. Students in classes where teachers were provided with…

Recommends improving preservice teacher assessment by providing multiple forms of on-campus laboratory experiences (e.g., microteaching, reflective teaching, simulations) that offer job-related tasks. Performance on the tasks could be assessed at multiple points and for various purposes (selecting preservice teachers and student teachers and…

Describes a study conducted by the U.S. Navy that compared training effectiveness and user acceptance of live instruction and six different alternative instructional television (ITV) technologies that had differing levels of audio and video communication. The ITV laboratory configuration is explained, and instructor preferences and skills are…

Describes school science as a rite of passage, and exposes problems in school science that are made visible through the use of this metaphor. (PR)

Discusses computer simulations in science education and presents the results of a study of 39 ninth-grade earth-science students to determine the effects of computer-simulated mineral identification activities on test performance. Results indicated no difference in test scores between the group using real minerals and the group using a computer…

Outlines a laboratory group program for engaging large numbers of undergraduate psychology students in faculty research at small liberal arts colleges with limited research resources. Participating in the group enhances the students' interest in and understanding of research and improves their chances of being accepted into a graduate program.…

Reports successful outcomes for a Teaching English as a Foreign Language module based on simultaneous oral translation from Arabic into English. Learners worked individually in a traditional language laboratory. Results show that simultaneous interpretation significantly improves learner performance and is an excellent tool for diagnosing learner…

Students' conceptions of three major artificial intelligence concepts used in the modeling of systems in science, fuzzy logic, neural networks, and genetic algorithms were investigated before and after a higher education science course. Students initially explored their prior ideas related to the three concepts through active tasks. Then,…

Much research has been compiled on service-learning, its benefits, and its influence on intrinsic motivation. Service-learning has been used as a method of teaching content in science education, civic education and history, business and marketing education, as well as other areas. However, a review of literature found no service-learning studies…

Teachers yearn for better writing skills from students. One way to achieve that goal is through a writing center, whether for basic writers or for the Harvard-bound student. But just because there is a writing center does not mean teachers are necessarily pleased with it. Center directors need time to talk to teachers about the center, make them…

A communicating science module was introduced into an advanced undergraduate physical chemistry laboratory course. The module was integrated into the course such that students received formal instruction in communicating science interwoven with the chemistry laboratory curriculum. The content of the communicating science module included three…

This standard lesson on identifying salt and sugar crystals expands into an opportunity for students to develop their observation, questioning, and modeling skills. Although sugar and salt may look similar, students discovered that they looked very different under a magnifying glass and behaved differently when dissolved in water. In addition,…

Purpose: Proteomic methodologies offer promise in elucidating the systemwide cellular and molecular processes that characterize normal and diseased thyroarytenoid (TA) muscle. This study examined methodological issues central to the application of 2-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis (2D SDS-PAGE) to the study of…
