Describes an integrated thematic unit for children from kindergarten to third grade. Explains that the unit incorporates reading, speaking, writing, science, mathematics, social studies, and art into the study of whales. Suggests learning activities on echolocation, migration, measurement, scrimshaw, history, and human interaction with the…

This study (n=192) examined the use of analogical instruction to overcome misconceptions about conservation of matter. Students who understood the concept conservation of matter when iodine was evaporated were able to transfer their understanding to the evaporation of acetone. This indicates that teaching by analogy can be an effective tool in…

Data from the 1983-84 Israeli IEA (International Association for the Evaluation of Education Achievement) science study were used to explore gender-related differences (and their determinants) in the learning of science. The study (n=1974) involved several measures of science learning, 10 attitudinal measures, and items and errors classification.…

Study compared two generations of seven high school chemistry texts (1970/1973) and current editions analyzed for gender fairness in illustrations and concrete analogies. Among conclusions was there were significant differences between the old textbooks and newer textbooks in relative frequencies of illustrations of men and woman and no…

This study investigated whether Science Curriculum Improvement Study or more recent interpretations of the learning cycle could be used by teachers to engage students in social constructivist learning. Two researchers and six science teachers implemented instruction based on the reciprocal use of language and action. Changing beliefs and practices…

Reports a study (n=41) of the effectiveness of in-depth, conceptually integrated instruction delivered via a videodisc program in eliminating children's alternative frameworks in science. This curriculum, which did not directly address alternative frameworks during instruction, changed 92% of the alternative frameworks held by students to…

Discusses the use of answering machines to teach astronomy to students while they are home. Provides directions on prelesson instruction; how to prepare the taped lessons; parent involvement; and lesson implementation. (MDH)

Spreadsheets are well suited to many geochemical calculations, especially those that are highly repetitive. Some of the kinds of problems that can be conveniently solved with spreadsheets include elemental abundance calculations, equilibrium abundances in nuclear decay chains, and isochron calculations. (Author/PR)

Describes a take-home experiment in which students measure the diffusion of acid through acid-filled capillary tubes immersed into base solutions and vice versa. Students represent and analyze the effects of ambient temperature, molecular weight, and concentrations of the solutions on that movement. (MDH)

Discusses the use of videodisk technology to teach biology. Presents videodisk selection criteria for biology teachers, lists 13 biology videodisks and their suppliers, and lists videodisks offered with biology textbooks. (MDH)

Describes Socratic Dialogue Inducing (SDI) laboratory methods and procedures developed to increase conceptual understanding in introductory physics laboratories. Gives an example of a typical beginning SDI lab manual section and a representative Socratic dialogue. Describes several examples of laboratory experiments developed for the SDI method.…

Through a review of the literature, looks at instructional and curricular issues related to the student-as-scientist model and the critical nature of the teacher's role in expanding school science activities to include this model. (SM)

Explores what constitutes an explanation for a science teaching event, noting conceptual-analysis-of-teaching and task-analysis approaches. Examples of various categories and distinctions are provided, drawing on data from pre- and postlesson discussions of an experienced teacher's seventh grade science lesson. The Science Teacher Thinking…

Outlines a reading program at Butcher Children's School in Emporia, Kansas, that allows the teacher to create a literate environment in which beginning readers develop their abilities, meet district goals, and develop a lifelong love of reading. Asserts that flexibility and the integration of subject matter are important factors. (PRA)
