Changes are occurring within Brazilian institutes of higher education; currently several universities are reviewing their course offerings and teaching approaches to determine if they meet the needs of today's undergraduate students. When changes are made to the curriculum of experimental courses, there should be an understood guarantee that all…

With each passing year, the public expects more of schools and teachers. Curricula become more complex, student populations become more diverse, responsibilities are added, and, except for resources, very little is taken away. Fundamentally, teachers are held responsible for everyone and everything that goes on in their classrooms, an awesome…

An objective of the American Chemical Society is to promote alternatives to landfilling for the disposal of laboratory chemical wastes. One method is to reduce the amount of chemicals that become wastes. This is the basis for the "less is better" philosophy. This bulletin discusses various techniques involved in purchasing control,…

This book is designed to develop sequentially a range of concepts and skills relevant to the basic disciplines of science. Emphasis has been given to the knowledge basis of science, the social context of science, design and technology, and knowledge and skills relevant to personal development. Students are provided an opportunity to engage in…

This paper on science instruction for learners with mental disabilities reviews the limited literature base in the field and provides practical information on teaching science in special settings. To assist in implementing best instructional practices in science education, the paper discusses the curricular make-up of science instruction; various…

The manual provides information on teaching techniques and services, materials, equipment, and publications for teaching chemistry to physically handicapped students. Section I addresses the classroom in terms of common needs, lecture/discussion techniques, and special arrangements. Section II covers the laboratory with general guidelines and…

This article details two demonstrations involving color changes. Included are "Manganese Color Reactions" and "Flame Colors Demonstration." Include a list of materials needed, procedures, cautions, and results. (CW)

Argues that with the increase in hands-on approaches to science, teachers are using more hazardous science demonstrations with less conceptual understanding than they should have. Poses questions for discussion within the chemical education community regarding the presentation of demonstration-based sessions at conferences. Stresses the…

With thousands of activities available, how does a teacher select activities appropriate for the classroom? Describes the guidelines of the "Science Activity Filter," which provide a useful protocol for evaluating science activities for their value in the classroom, allowing the teacher to use resources effectively, minimize discipline and safety…
