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 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)

"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…

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)

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)

Described is a series of five related microcomputer-based laboratory analysis programs that are used by students in a college calculus-based physics course. With minor modifications these programs, which are written in BASIC, could be used in most beginning undergraduate laboratory science courses. (RH)

Discusses the role of the laboratory in teaching chemistry, describing and differentiating between empirical laboratory investigations and discovery laboratory investigations. Also points out that if a laboratory is designed to illustrate something, it should be the scientific method. (JN)

Describes a system that monitors intestinal motility in vivo which is very sensitive, minimally injurious to the tissue, and inexpensive. Used are two balloons, one of which is inserted into the intestinal lumen and the other suspended from a force transducer. (CS)

This selected collection of How-To-Do-It articles published in the American Biology Teacher during the past six years presents experiments that can be conducted safely under properly trained and responsible teacher supervision. Contents include: (1) "General Biology and the Nature of Science"; (2) "Cells and Molecules"; (3) "Microbes and Fungi";…

This handbook was prepared to help science teachers, administrators, and other school staff members understand and avoid situations in which accidents might occur in the science laboratory, on field trips, or during outdoor education experiences. Suggestions contained in this publication are generally agreed upon and recommended for consideration…

Educators seeking support for continuation of science laboratory instruction can find information in the ERIC data base. Sections cover: (1) what's available; (2) beliefs about the role of laboratories; (3) what critics say; and (4) research evidence. (MP)

Discusses how holography can be used as part of undergraduate physics laboratories. The authors propose a single beam technique of holography, which will reduce the recording scheme as well as relax the isolation requirements. (HM)

Describes the use of a laboratory-based exam in mechanics that makes students use metersticks, stopwatches, and spring scales to examine physical situations, make some calculations to predict what will happen, and then test their predictions. Includes a description of the lab stations for the actual exam. (JRH)
