A set of interactive, computer-simulated experiments was designed to respond to the large range of individual differences in aptitude and reasoning ability generally exhibited by students enrolled in first-semester general chemistry. These experiments give students direct experience in the type of decision making needed in an experimental setting.…

The purpose of this study was to determine the relative effectiveness of two instructional approaches upon the attitude, achievement, and retention of fourth, fifth, and sixth graders studying a 3-week unit on the metric system. A laboratory approach, in which students measured three-dimensional objects with tools scaled in metric units, was…

This brochure lists science objectives developed by the Texas Education Agency considered basic or essential for mid-point level (grade 5 or 6) and for high school exit level. Objectives are grouped under three major headings: (1) science processes; (2) laboratory manipulative skills; and (3) use of science and technology (content). Suggestions…

This publication was developed as a portion of a two-semester sequence commencing at either the sixth or seventh term of the undergraduate program in electrical engineering at the University of Pittsburgh. The materials of the two courses, produced by a National Science Foundation grant, are concerned with power conversion systems comprising power…

This annotated bibliography of marine education contains 35 documents published in 1976-1977 and an unpublished masters thesis (1969). The majority of the works are laboratory projects in marine science for students at the elementary and secondary school level. Other entries include marine science units for science teachers, marine education grant…

This handbook, prepared in field-test version, is intended to provide in-service teachers with "guidance in the development of the basic concepts of measurement." The basic assumption on which this guidance is based is that "hands-on" experience is the most appropriate method of teaching metric measurement. An additional premise is that students…

A mathematics laboratory is discussed in terms of (1) administrative support, (2) personnel, (3) curriculum design, (4) flexibility in design and equipment, (5) professional counseling, and (6) motivational devices. The discussion focuses upon the remedial math lab at Alvin Community College, Alvin, Texas. The roles of instructors, lab…

The purpose of this brochure is to introduce teachers to the University of Hawaii's language laboratory facilities and services. Key features built into the laboratory are student cartridge decks and the dual-teacher console. The procedures and functions of the language laboratory are described in three major sections: (1) student facilities, (2)…

This book is intended to serve as a source of ideas for devising simple scientific activities, investigations, and experiments and for the construction of necessary equipment using available materials. This revision of an earlier edition reflects modern approaches to science teaching at the elementary and secondary school levels. This edition has…

This ERIC/SMEAC Newsletter contains a bibliography of 41 references concerning mathematics laboratories and 26 references on metrication that have been listed in RESEARCH IN EDUCATION, CURRENT INDEX TO JOURNALS IN EDUCATION, and other sources. (DT)

Trace organic analysis (TOA) is seen as a more useful way to quantify environmental pollutants. Current practices and future trends are discussed in detail. Seven steps in TOA are identified: collection, storage, extraction, concentration, isolation, identification, and quantification. (MA)

Attainment of laboratory course objectives was compared for tenth and twelfth grade Israeli students using two chemistry curricula: An Experimental Chemistry Program for Secondary Schools (ECPSS) and the CHEM Study program. ECPSS students more often than non-ECPSS students, and ECPSS girls more often than boys felt they had achieved the…

Proposes a series of experiments that integrate analytical techniques in order that students are able to compare, based on their laboratory results, the relative reliabilities of the most common therapeutic drug monitoring methods. Discusses materials, procedures, and results of three experiments on the determination of drug concentration by…

Describes a simple, inexpensive experiment in which students determine the heats of combustion of common solid, liquid, and gaseous fuels. The experimental apparatus, procedures, calculations and results are discussed. (CW)

Introduces a photogate arrangement using a photo-reflective sensor for air track experiments. Reports that the sensitivity to sunlight can be eliminated and a mechanically more convenient package produced. Shows the mounting, circuit, and usage of the photogate. (YP)
