The purpose of this study was to construct an instrument to be used in the collection and evaluation of data upon which to base decisions regarding the scope and character of vocational programs in individual high schools. Following a review of pertinent literature, a list of categories of information needed was drafted and organized under four…

This report is the fourth in a series of four reports dealing with the development of performance-oriented driver education objectives through an analysis of the driver's tasks. Described in this volume are the methods used to develop a set of instructional objectives for driver education courses and an evaluation instrument for evaluating…

This report is the second in a series of four reports dealing with the development of performance-oriented driver education objectives and a set of measuring devices for evaluating attainment of the objectives. Included are descriptions of the analysis of driver's tasks and the evaluation of behavior criticality. During the analysis process, the…

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)

A PET microcomputer is used as an accurate and programmable timer to support data acquisition from velocity experiments covering falling, rolling, and sliding objects, and human velocity, acceleration, and power measurements. The inexpensive instrumentation is simple and easy to use and compares favorably with conventional, more expensive…

Contends that the nature of physics has been misrepresented by blurring or ignoring important distinctions between "errors" and "discrepancies" and that dealing with these and related problems can improve students' enjoyment of labs and understanding of physics. Nature of physics, role of experiments, experimental errors, and error analysis are…
