Designed for use in institutional self-studies and program reviews, these guidelines provide a comprehensive model for chemistry and chemical technology programs in two-year, associate-degree-granting colleges. The eight sections of the guide suggest 90 standards in the areas of: (1) chemistry program mission and periodic program review; (2)…

On the premise that many laboratory instructors lack knowledge about chemical toxicity, this study investigated three areas: (1) chemicals used in the academic laboratory which pose a health hazard; (2) ways of reducing toxicity in the laboratory (with attention to the apparent lack of teacher training which contributes to the cause of the problem…

This paper presents research designed to study the West African Examination Council's (WAEC) policy and its impact on teaching chemistry in Nigerian secondary schools. Five knowledgeable public figures in Nigeria and Great Britain were interviewed concerning policy formulation and implementation. Five pertinent documents were analyzed.…

This manual is designed to supplement an existing physical science curriculum and to assist in providing the learning experiences required to implement an effective course. The first chapter outlines the purposes of this manual and provides a set of teaching tips. Topics such as electricity, wave motion, light, sound, periodic table and nuclear…

This paper describes the rationale for, methodology of, and some early results from a longitudinal study on science teachers' knowledge of science. Each of the participants is a university science graduate with a post-graduate university training for secondary school science teaching. The study focuses on two issues: (1) variations that occur in…

This document reports on a study to develop an empirical method for analyzing and reporting classroom interaction data. Data were collected according to a classroom observation scheme involving the frequency of various interactions (question, answer, or management), the cognitive level of the interaction, the role of the actor, the level of…

This document was developed to provide eighth-grade teachers in New York City with a sequence of instructional activities in science. The major portion of the guide is divided into four instructional units. The first unit, "Chemistry," includes lessons and activities on liquid solutions, suspensions and emulsions, acids, bases,…
