This instructor's manual presents material on basic bacteriological laboratory procedures as required by Federal Register Water Quality Guidelines. Course topics include: characteristics, occurrences, and significance of bacterial indicators of pollution; bacteriological water quality standards and criteria; collection and handling of samples;…

This series of experiments seeks to provide laboratory exercises which demonstrate concepts in Earth Science, particularly meteorology. Materials used in the experiments are easily obtainable. Examples of experiments include: (1) making a thermometer; (2) air/space relationship; (3) weight of air; (4) barometers; (5) particulates; (6) evaporation;…

This is one of several study guides on contemporary problems produced by the American Association for the Advancement of Science with support of the National Science Foundation. This guide is designed to be used by teachers at the undergraduate college level and by college students intending to become teachers. The guide includes eight units: (1)…

This second volume, a compilation of reprints of experimental notes in physics, was prepared by the American Association of Physics Teachers (AAPT) Committee on Apparatus and by the AAPT Executive Office in response to requests received by the Association for a completely new edition. The goal of the Committee was to provide a selection of…

This volume is one in a series which outlines performance objectives and instructional modules for a course of study which explains the relationship and function of the process units in a wastewater treatment plant. Examples of modules include measuring settleable matter, total solids, dissolved solids, suspended solids, and volatile solids. The…

Ninety students in an introductory chemistry class were divided into three groups to test the power of algorithms to increase logical thinking abilities. The experimental group received approximately 10 hours of laboratory instruction based on the use of procedural algorithms. Experiment and control groups were tested for logical thinking…

The first part of this yearbook treats the characteristics and needs of the slow learner, the research literature, behavioral objectives, and the creation of a favorable learning environment. The second part, meant to provide more specific help for the classroom teacher, deals with teaching techniques, multisensory aids and activities, mathematics…

The process of establishing an individualized mathematics program is discussed. An annotated list of references covering program and course goals and objectives, diagnostic and achievement tests, teacher reference books, and activity sources is provided. Twenty-one articles from "The Arithmetic Teacher" which offer a rationale for the activity…

Presented are the following articles: A Role for Computers in Teaching Biology; The Laboratory in General Microbiology; Rectifying the Misnomer; The "Message" of Pioneer 10: Interpretation and Role Playing for Beginning Science Students; The Project Oriented Laboratory as an Effective Teaching Method for Nonscience Majors; Environmental…

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 arose out of a concern for the type of college science courses being offered to non-science majors. Of particular concern is the traditional method of laboratory instruction, with its emphasis on specific techniques and instrument manipulations rather than promoting an understanding of the processes, concepts, and methods of…

The Australian Science Education Project is producing a series of units designed for use in grades 7 - 10. This first trial edition contains a teachers guide, providing an overview of the unit and advice on mice management and classroom organization; booklets for students ("Mammals,""Investigations,""Care and Handling of…

This guide includes a chapter on concepts related to measurement, a chapter describing the various measuring instruments that are used in the field, and a chapter indicating realistic class projects using field instruments. Twenty-three plates contained in the publication are designed as masters to make transparencies for classroom instruction. A…

The purpose of this study was to design a beginning course in geology which not only accents the sociological implications inherent in the study of geology, but also presents the learner with the opportunity to solve geological problems by using laboratory techniques. A curriculum rationale was designed in which those environmental problems with…

The attitudes of 32 teachers, in 30 schools, toward Biological Sciences Curriculum Study (BSCS) courses were compared to their students' perceptions of laboratory and classroom activity measured by the Biology Classroom Activities Checklist and the Biology Laboratory Activities Checklist, respectively. The results indicate no relationship between…
