This article reports on the development of a methodology that integrates virtual and hands-on inquiry in a freshman introductory biology course. Using a two time x two order-condition design, an effective combination (blend) of the two environments was evaluated with 39 freshman biology participants. The quantitative results documented no…

This article (1) defines risk management and discusses alternatives to treating exposures facing those operating chemical laboratories; (2) indicates how two Virginia universities did or did not apply the risk management concept to their laboratory settings; and (3) identifies potential sources of information on this subject.

In response to the Texas Hazardous Communication Act (THCA) of 1986 which raised many new health and liability issues regarding students in science laboratories, a laboratory safety survey was generated for use in evaluating laboratory safety. This article contains the easy-to-use survey. (ZWH)

"Keeping Pace" has several goals. First, it strives to add to the body of knowledge about online education policy and practice and make recommendations for advances. Second, it serves as a reference source for information about programs and policies across the country, both for policymakers and practitioners who are new to online…

Describes how a planetarium was constructed on the ceiling of a traditional physics laboratory. Similarities and differences between the "poor man's" planetarium and other planetariums are noted. (JN)

This document presents laboratory safety rules for Arkansas K-12 schools which were developed by the Arkansas Science Teachers Association (ASTA) and the Arkansas Department of Education (ADE). Contents include: (1) "Laboratory Safety Guide for Arkansas K-12 Schools"; (2) "Safety Considerations"; (3) "Safety Standards for Science Laboratories";…

Lists 46 household chemicals readily available at local stores by common name, chemical name, chemical formula, and typical commercial source. Suggests that school budgetary constraints can be eased by this practice and that students can become more chemically literate as consumers. (JJK)

This manual provides practical advice on the appropriation, conservation, and documentation of a marine biological reference collection, in response to needs expressed by Mediterranean Arab countries. A reference collection is defined as a working museum containing a series of specimens with which biologists are able to compare their own material.…

Described is an acid-leaching facility at Macquarie University in Australia for teaching paleontology. The facility is used for teaching both undergraduate and graduate students and for research by staff and graduate students. Drawings of the facility are included and courses are described. (Author/RH)

Offers a simple model for estimating vapor concentrations in instructional laboratories. Three methods are described for measuring ventilation rates, and the results of measurements in six laboratories are presented. The model should provide a simple screening tool for evaluating worst-case personal exposures. (JN)

Discusses possible reasons for the variations in current biochemistry laboratories (including staff expertise, equipment limitations, no laboratory textbook with modern experiments, and diverse student backgrounds). Also proposes a more uniform coverage of subject areas and techniques by providing a sample course format. (JN)

This publication presents examples of inquiry-based science teaching in which students develop an understanding of the natural world. Sections include: (1) "Connecting Students to Science and the World" (Jennifer Stepanek); (2) "Apple Orchard Lush with Life's Lessons" (Helen Silvis); (3) "Student Scientists Team Up with the Pros" (Amy Sutton); (4)…

Discusses the changes that schools will have to make to ensure that all lab exercises are done in compliance with the new chemical hygiene law. Two tables are included: (1) Chemical Hygiene Compliance; and (2) Duties of a Chemical Hygiene Officer. (ZWH)

Describes various hazards associated with electricity and electrical usage that can result in fire, explosion, burn, and shock. Presents diverse techniques and methods that one can utilize to protect laboratory personnel from common, yet dangerous, electrical hazards. (Author/JJK)

Presents and discusses results (based on data from 1,082 microcomputer-using schools) which suggest that where schools locate their microcomputers has an impact on how they are used. Locations examined include classrooms, laboratories, libraries, special rooms, and mixed locations. (JN)
