This article examines the 11-year Soviet experiment with boys' schools as a way to cast new light on scholarly research and public debates about single-sex education. Drawing on archival and published materials by educators who described school conditions, identified problems, suggested reforms, and evaluated remedies, the author argues that…

Experimental studies conducted since 1980 were reviewed. Each of the 34 studies concerning problem solving is briefly summarized, followed by comments, criticisms, and/or concerns. A summary indicates that experimental research of the 1980s seems to focus on: (1) children's processes, understanding, functioning, difficulties, and representations;…

Describes a method to determine the thermal diffusivity of a polymer, which is suitable for the undergraduate laboratory. It serves as a practical demonstration of classical Fourier theory. (Author/HM)

Discusses the problem of serious dangers in current and backlist chemistry experiment books. Discarding of older books and careful evaluation of the dangers inherent in newer books are recommended. Safe alternatives are suggested, including some criteria for evaluating dangers, and a safer approach used by a current author. (EM)

Discusses the use of direct demonstration of the connections among the science process skills and the content areas of science. (MKR)

Describes problems in teaching problem solving and summarizes research in this area. Presents Guided Design or Guided Decision Making as a problem-solving approach in which groups of students work their way through a model of the problem-solving process as they wrestle with a discipline-specific situation. (PR)

Reviews the work of the Commission on Undergraduate Education in the Biological Sciences (CUEBS) from 1964 to 1972. Suggests that now is the appropriate time to reassess their efforts, to build on their successes, and to use their experience to attack some of the continuing problems facing biology education.

Videotex is a generic term used for any electronic system that can be used to retrieve both print and graphic computer-based information via video display monitors or specially adapted television sets. Both one-way (broadcast videotex) and two-way (interactive videotex) exist; these can be used as an information source, a delivery medium, a…

Describes the phenomenological and microscopic aspects of solid-state diffusion in an electric field and presents a Monte Carlo method which is used to stimulate an atomistic model of diffusion in an electric field. The Nernst-Einstein relation is also discussed. (HM)

This monograph discusses the current practices associated with the conduct of a research and experimentation program in technology education. It describes the background and bases of the program, the role of the teacher of research and experimentation, and advantages of the program. Next, the environment of the program is addressed, including the…

As the amount of resources allocated to out-of-school (OST) programming and policymakers' demands for research-based results increase, there is increasing interest in rigorous research designs to examine OST program outcomes. This issue of "Out-of-School Time Evaluation Snapshots" reviews 27 quasi-experimental and experimental OST…

This ERIC Digest presents a brief description of some applications and findings of the microcomputer in science classrooms. It is suggested that microcomputer simulations are at least as effective as hands-on experiences for some cognitive outcomes and may in fact enhance these outcomes when the simulations are sequenced to follow hands-on…
