Describes an experiment developed at Brooklyn College (New York) in which the preparation and ammonia analysis of an amminenickel(II) chloride is extended to include a spectrophotometric analysis for nickel. Discusses the materials needed and the procedure for the experiment which takes nine hours of laboratory work. (TW)

Describes the construction of a low-cost (about $70.00) alternative to the commercial fraction collector. Outlines the separate parts of the collector and provides a schematic of electronic circuitry of the instrument. Lists special items required for the development of this project. (TW)

Addresses the introduction of low cost equipment into high school and college physical science classes. Examines the properties of an "ideal" operational amplifier and discusses how it might be used under saturated and non-saturated conditions. Notes the action of a "real" operational amplifier. (TW)

Discusses a study which examined the interpretive process used by high school chemistry teachers in translating curriculum materials into classroom practice. Results indicate that differences exist among teachers but that commonalities are greater. Explains the functional paradigm concept and its value for the interpretation of curriculum…

Examines how humans have treated mammals throughout history. Identifies both the problems facing animals and the corrective efforts that are currently underway. Student activities include stories, games, a scavenger hunt, a mural, a puzzle, and a survey focusing on mammals. (ML)

Describes the procedures and techniques employed in a peer-group approach for promoting conceptual change. Explains how a series of cards were used to challenge student's conceptions of energy. Suggests that a systematic development of skills is needed to maximize the benefits of a peer group discussion approach. (ML)

Provides an overview of the educational program of the Seychelles and focuses on an evaluation of the final phase (P7-P9) of the nine-year school program. Reports how findings from content analyses of materials, teacher and student interviews, and student test results were used to develop the new Seychelles Integrated Science program. (ML)

Describes a program of demonstration experiments used to stimulate interest in chemistry, specifically aimed at increasing university chemistry enrollments. Discusses program goals, experiments, design criteria, and several caveats related to the development of such a program. (JM)

Outlines the learning environments, interdisciplinary curriculum, and campus/schedules for the environmental education program at the New Jersey School of Conservation at Montclair State College. Major areas of study include environmental communication, advocacy, technology, and instruction, and participants range from third graders to university…

Desribes a chemistry course (taught in summer for graduate credit) for K-6 teachers to help promote teaching of chemistry as an experimental science at the elementary school level. Also describes another chemistry course for elementary school teachers, focusing on the laboratory component and experiments. (JN)

The Mt. Bethel Elementary School in Marietta, Georgia, cooperated with the Chattahoochee Nature Center to develop a nature trail in a neighboring wooded lot. The program used the school's current science curriculum, depended on students to construct the trail, and involved direct teaching and inservice assistance from nature center personnel. (PGD)

Examined the effects different communicators (science methods instructors, supervisors, graduate assistants, and others) had on the attitudes of 25 elementary education majors toward science and science teaching, focusing on which communicators were perceived as being the most credible. (DH)

Recommendations from British Columbia teachers in elementary (N=1322) and junior secondary schools (N=309) indicate strong support for emphasis on practical aspects of preservice teacher education. Practice in science teaching, techniques of science teaching, and lesson planning were rated highest. Laboratory safety, reading, and writing should…

The three phenomena of independence, dependence, and interdependence interact in rather complex ways in African countries. These interactions, in the context of education, are examined through case studies of two regional African educational organizations: the Science Education Programme for Africa and the African Curriculum Organization. (RM)

Documents the educational use of spreadsheets through a description of exploratory work which utilizes spreadsheets to achieve the objectives of Conway's Game of Life, a scientific method game for the development of problem-solving techniques. The implementation and classroom use of the spreadsheet programs are discussed. (MBR)
