One of the major challenges facing people committed to Teaching Safety in High Schools, Colleges, and Universities is keeping up with both the wide range of relevant technical information about potential hazards (ranging from fire protection to chemical hazards to biological issues) and the ever-changing world of safety regulations and standards.…

This document contains an annotated bibliography aimed at the teaching of the physical sciences at the tertiary level to those who wish to become more informed about teaching related research evidence and undertake science education research. The bibliography offers an overview of teaching and learning in the physical sciences and key references…

Feedback from assessments should be the foundation for improvements students make in their lab work. Therefore, in this study, a standard rubric that reflected the scientific method was employed as an intervention to assess student lab write-ups. Students preformed three labs all based on consumer research. The first lab was completed without the…

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…

This bulletin responds to frequent requests for practical information relating to equipment and supplies for teaching science in small high schools. Laboratories for science courses have been for several decades necessary parts of every high school teaching the sciences. This bulletin is a brief survey of the necessary equipment to teach the…
