Describes the use of a quiz that asks elementary but probing questions about chemistry and delivers the message to students that they have much to gain from chemical education. Arises out of concern over lack of student motivation in chemistry. (DDR)

The Perfect Eye model simplifies solutions to a wide variety of optometry instructional problems by facilitating student understanding of the interaction among lenses, objects, accommodation, and ametropia. The model is based on the premise that inside every eye is a perfect (emmetropic) eye, and that the physiological eye is a combination of the…

Advocates removing the taboo regarding anthropomorphism and teleology in biology education. Argues that for high school students, accepting such formulations does not necessarily imply anthropomorphic or teleological reasoning. Further, living organisms seem goal-oriented because of their adaptation for survival. Concludes with the argument that…

Differences in the status of ontological categories on the concept maps of secondary-, undergraduate- and graduate-level chemistry students were analyzed with the "Pathfinder" scaling algorithm and multidimensional scaling. Results indicate differences among groups in the structural significance of abstract process-related nodes and…

Describes an approach to teaching the conceptually demanding topic of fluids which focuses on promoting student teachers' continual evolution toward a suggested scientific model. Discusses the approach in detail. Contains 45 references. (DDR)

Discusses the role of chemical-equation problem solving in helping students predict reaction products. Methods for helping students learn this process must be taught to students and future teachers by using pedagogical skills within the content of chemistry. Emphasizes that solving chemical reactions should involve creative cognition where…

Teachers sometimes create boxes that isolate students and hinder authentic learning, using the classroom, the unit, and the textbook as the boundaries of the instructional approach. (DDR)

Examined effectiveness of conflict resolution training integrated into a curriculum unit on friendship taught daily for 4 consecutive weeks to kindergartners in a midwestern suburban school. Found significant differences in trained and untrained children's knowledge and retention of the conflict resolution procedure, willingness and ability to use…

Investigated the nature and origins of early ideas about the environment held by children. Found that data explain aspects of the knowledge children have about various environments before they enter school, the development of this knowledge from ages 4 to 6, and young children's developing understanding of the impacts of environmental changes.…

Three studies tested the hypothesis that children's difficulty acquiring dimensional adjectives, such as big and little, is a consequence of how these words are used by adults. Findings indicated that children easily acquired novel dimension words when such words were used in a strictly comparative fashion, but had difficulty when also exposed to…

Reviews science education research into representations constructed by students in their interactions with the world, its phenomena, and artefacts. Features discussions of mental models, conceptual models, and the activity of modeling. (Contains 30 references.) (Author/WRM)

Explores student ability to differentiate and make mappings between quantities in different domains before and after a relevant curricular experience. Contends that conceptual bootstrapping involves a multistepped mapping process that is facilitated through classroom dialog, problem solving, and instruction. (Author/DKM)

Identifies four different types of science stories: (1) heroic; (2) discovery; (3) declarative; and (4) politically correct. Examines the philosophical assumptions that underpin heroic science stories. Considers the implications of these stories in the science classroom. Contains 33 references. (DDR)

Reports on the application of Gowin's epistemology to examples from geological inquiry which yield criteria of excellence responsive to the demands characteristic of geological problems. Supporting this approach is a case study about how geologists apply analogies. Contains 33 references. (DDR)

Discusses how scientific knowledge emerges from social, natural, political, cultural, historical, and economic contingencies of scientific work. Illustrates the advantages of familiarity with research in science and technology. Contains 96 references. (DDR)
