As part of a series of studies assessing micro-teaching and video recording in vocational and technical education, this study was designed as a field test of those techniques in inservice vocational teacher education. The two techniques were tested at three sites in New York State and involved the collection of data in terms of teacher…

The purpose of this study was to compare a linear strategy of computer-assisted instruction (CAI) with a tutorial strategy of CAI and to ascertain the effectiveness of each in teaching selected cognitive elements of orthographic projection to sixth grade students. The comparison was made in terms of student achievement on the final task and the…

This report compiles data that describe education vouchers, discuss how an education voucher experiment such as OEO's proposed project would function, and present advantages and disadvantages of vouchers. The report presents OEO specifications for its proposed longrange experiment and explains variations in other voucher systems. Problems of…

This document describes a project designed to test the effectiveness of an elementary school music curriculum guide that contained behavioral objectives and structural sequencing compared to a "traditional" guide. More than 3200 5th and 6th grade pupils taught by 56 teachers in the Houston, Texas, Independent School District participated in the…

This report summarizes the management support activities of Education Turnkey Systems, Inc. for the O.E.O. Performance Incentive Remedial Education Experiment. Included are sections on the implementation, the monitoring, and the implications of this experiment that tested performance contracting as a technique of instruction in public school…

Four experiments comparing behavior of children from Los Angeles, California, and Nuevo San Vicente, Baja California, Mexico, were conducted to analyze cooperative and competitive behavior of Anglo American city and Mexican rural children. Eighty children from each setting, 40 of age 7-9 and 40 of age 10-11, equally divided by sex, served as…

THIS RESEARCH CONCERNING CONCEPTUAL BEHAVIOR INVESTIGATED BOTH THE DEVELOPMENTAL ASPECTS OF CONCEPTUAL BEHAVIOR IN A CONTROLLED LABORATORY SITUATION AND THE RELATIONSHIP OF CONCEPT LEARNING IN THIS LABORATORY SETTING TO ACHIEVEMENT IN CURRICULAR AREAS OF JUNIOR HIGH SCHOOL. THE GENERAL PLAN FOR THIS STUDY INVOLVED STRATIFIED RANDOM SELECTION AND…

A conservation problem of numerical equivalence which 80% of adults reliably fail and 40% of third graders pass was developed, and responses of 188 subjects (Grades 2, 3, 5, 7, 9, 11 and college) to it and related number conservation and probability problems indicated that the differences in nonconservation were rooted in subjects' different…

This vocational physics individualized student instructional module on jacks (simple machines used to lift heavy objects) contains student prerequisites and objectives, an introduction, and sections on the ratchet bumper jack, the hydraulic jack, the screw jack, and load limitations. Designed with a laboratory orientation, each section consists of…

The report describes two experiments involving the ability of preservice social studies teachers to stage score moral thought statements. Stage scoring is defined as keeping a record of statements in accordance with the stages of moral development originated by psychologist Lawrence Kohlberg. The two experiments involved the use of three stage…

A major theme of this series of papers is the need to build evaluation and experimentation as a component part of educational planning.

One hundred forty-five studies concerning individualized programs of mathematics instruction were reviewed. The summary of results presented tends to support the effectiveness of individualized programs, but notes possible difficulties in implementing them. (SD)

Presents task analysis of the laboratory inquiries of the BSCS Yellow Version. Three important deficiencies are identified: (1) Students do not identify and formulate problems; (2) Students get little chance to conduct investigations; and (3) Post-laboratory discussions are not indicated. (MA)

Discusses the benefits of thermochromic transformations for studying thermodynamic properties. Describes an experiment that uses a commercially available dye, attains equilibrium rapidly, employs a simple, single-beam spectrophotometer, and is suitable for both physical chemistry and introductory chemistry laboratories. (TW)

Describes how a Polaroid camera can be modified for spectroscopic experiments. Reviews experimental procedures and discusses results that students can obtain within one normal laboratory period. Suggests additional experiments for investigating emission from other sources. (ML)
