An important aspect of developing science literacy for all students is developing science-literate teachers. With the implementation of the No Child Left Behind Act, many middle school teachers found themselves in a position where they were no longer qualified to teach middle school science. This study was designed to help science teachers…

A new learning unit in chemistry, "Case-based Computerized Laboratories" (CCL) and Computerized Molecular Modeling" (CMM) was developed at the Technion. The CCL and CMM curriculum integrates computerized desktop experiments and molecular modeling with an emphasis on scientific inquiry and case studies. Our research aimed at…

Developments in the laboratory-based teaching of physics and astronomy are resulting from the collaboration between conventional and distance teaching universities. The collaboration, piCETL, is one of the Centres for Excellence in Teaching and Learning established as a result of a broad initiative by the Higher Education Funding Council for…

In the ever-expanding realm of science, educators struggle to share new discoveries and techniques with their students. Keeping abreast of recent advances can be daunting, even for the most motivated teacher. Fortunately, the National Science Foundation's (NSF) Research Experiences for Teachers (RET) program helps educators keep up with the…

The law of conservation of momentum is one that students often have difficulties understanding. This experiment allows students to use childhood toys to examine and calculate the muzzle velocity of their favourite water gun by using an air track, a spark timer or data logger and the law of conservation of momentum in a one-dimensional case, a…

A laboratory project for a first semester biochemistry course is described, which integrates the traditional classroom study of the structure and function of biomolecules with the laboratory study of these molecules using fluorescence spectroscopy. Students are assigned a specific question addressing the stability/function of lipids, proteins, or…

The creative application of low-cost, readily available materials and techniques promotes inclusion and provides accessibility in the classroom and laboratory for students who are blind or have low vision. Difficulties encountered by these students include operation of laboratory equipment, execution of ordinary laboratory procedures, and use of…

Providing fair assessment with timely feedback for students is a difficult task with science laboratory classes containing large numbers of students. Throughout our Faculty, such classes are assessed by short-answer questions (SAQs) centred on principles encountered in the laboratory. We have shown recently that computer-assisted assessment (CAA)…

Conventional physics laboratory courses generally include an emphasis on increasing students' ability to carry out data analysis according to scientific practice, in particular, those aspects that relate to measurement uncertainty. This study evaluates the efficacy of the conventional approach by analyzing the understanding of measurement of…

A primary goal of the American Chemical Society Task Force on Laboratory Waste Management is to provide laboratories with the information necessary to develop effective strategies and training programs for managing laboratory wastes. This book is intended to present a fresh look at waste management from the laboratory perspective, considering both…

The occupational safety and health standards adopted for fourteen carcinogens are specified and discussed. Standards on benzidine and beta - propiolactone are reprinted in full as examples. (DT)

References pertaining to science facilities are organized and presented in the following categories--(1) biology facilities, (2) chemistry facilities, (3) physics facilities, (4) astronomy facilities, (5) elementary and secondary school science facilities, (6) college and university science facilities, and (7) planning and science laboratory.

This document on the undergraduate laboratory biology course is organized into 4 parts. Part 1 deals with the role of investigation in the undergraduate curricula. Chapters in this section deal with the time for laboratory reform; some special considerations in designing laboratory programs for nonmajors; the appropriate laboratory experiences for…

A massive concrete "waffle," riding on a bed of specially treated gravel and sand inside another building, provides the structural rigidity needed by the University of Rochester's Laboratory for Laser Energetics. (Author)

Discusses the role of the national laboratories as new sub-agencies of the Energy Research and Development Administration (ERDA). (SL)
