This booklet is one of the "Understanding the Atom" Series. The science of spectroscopy is presented by a number of topics dealing with (1) the uses of spectroscopy, (2) its origin and background, (3) the basic optical systems of spectroscopes, spectrometers, and spectrophotometers, (4) the characteristics of wave motion, (5) the…

This booklet was written for elementary school teachers who want suggestions of the type of activities suited to a mathematics laboratory. The emphasis is not that of a thorough survey of the available activities. Instead, the author uses selected examples to describe the spirit of a laboratory environment. The suggestions include arrangements of…

This teacher's guide on nuclear science is divided into two parts. The first part is a discussion of some of the concepts in nuclear chemistry including radioactivity, types of disintegration, radioactive decay and growth, and tracer techniques. The relevant experiments involving the use of radioisotopes are presented in the second part. The…

This is a report of a selective survey of training activities in the United States. Selection centered on the representative activities of a variety of institutions which served different audiences, had different goals, and different sources of funding. Most of the inventories were conducted in person by a committee member. The 14 reports are…

This volume contains chapters 8 to 13 of the ACS "Modern Chemical Technology" (ChemTeC) curriculum material which is intended to prepare chemical technologists. The content is centered around the background needed to understand the structure of the atom, covalence, electrovalence, elements and compounds, liquids and solutions, and chemical…

Included are a wide spectrum of space science articles which were developed and classroom tested by junior high school teachers. Concepts are developed through the use of historical perspectives, representational models, demonstrations, and student activities. The major emphasis is on student activities. Frequent use is made of tables and graphs…

Creative uses of labor training films, documentaries, and full-length feature films in labor education are examined and discussed. A need is seen for more authentic, professional training films. Typical discussion sessions are outlined for "The Shop Steward" and "The Grievance," two outstanding National Film Board of Canada…

Ventilation systems for factory safety demand careful planning. The increased heat loads and new processes of industry have introduced complex ventilation problems in--(1) ventilation supply, (2) duct work design, (3) space requirements, (4) hood face velocities, (5) discharge stacks, and (6) building eddies. This article describes and diagrams…

This collection of 10 working papers is designed to contribute to analysis of issues and appraisal of recommendations in "Learning and Living: The Report of the Provincial Committee on Aims and Objectives of Education in the Schools of Ontario," the 1968 "Hall-Dennis report" commissioned to develop aims and objectives and to…

Models were developed to identify important variables and their causal relationships to strategies of laboratory instruction in secondary school science. Data from student checklists, questionnaires, tests, and direct observations of laboratory activities were factor analyzed. Two teaching strategies identified by factor analysis were…

This study tested the possibility of using the optimization techniques of the response surface model in maximizing the response to a concept learning task. A secondary purpose was the investigation of the extent to which findings from concept learning experiments in laboratory settings would generalize to the learning of types of concepts…

This report is concerned with the extent and condition of academic and other facilities of higher education institutions in Maine. Information bearing on the use of these facilities and the plans of institutions for enrollment and plant expansion is included. A number of recommendations are made concerning the future role and location of public…

The effects on student teaching behavior of a relatively traditional, lecture-based, general secondary methods course are compared to the effects of a laboratory-oriented, competency-based course. The classroom performance of two groups of student teachers (30 of whom completed the competency-based course and 40 of whom completed the lecture-based…

This guide for Cosmetology is part of a public school effort to articulate secondary and post-secondary vocational education programs. It is organized in a pattern of behavioral objectives so that students may enter and complete the program in high school, or in a post-secondary program, or may transfer and continue without loss of time. Of the…

This handbook contains information that has been used in the high school laboratory by many teachers. Most of the experiments can be adapted for use as individual laboratory exercises or as teacher-student demonstrations. The resource material in this handbook should be helpful to all physics teachers as they continue to adapt their courses to…
