A laboratory experiment, based on a simple electric circuit that can be used to demonstrate the existence of real-world "related rates" problems, is outlined and an equation for voltage across the capacitor terminals during discharge is derived. The necessary materials, setup methods, and experimental problems are described. A student laboratory…

This report evaluates a project for secondary school education teachers in northeastern Texas. The objectives of the project were to: (1) train the secondary and middle school teachers of special education to use the Science Activities for the Visually Impaired/Science Enrichment for Learners with Physical Handicaps (SAVI/SELPH) curriculum; (2)…

Bridges and similar constructions are highlighted in this book of guided lessons and activities for secondary school physics students. This program was developed by the Physics Curriculum Development Project under the auspices of the Physics Curriculum Innovation Committee. Contents include: (1) "Introduction" (presenting a rationale for…

The Long Duration Exposure Facility (LDEF) has been designed to take advantage of the two-way transportation capability of the space shuttle by providing a large number of economical opportunities for science and technology experiments that require modest electrical power and data processing while in space and which benefit from postflight…

To demonstrate that properly designed laboratory instruction does provide affective and higher order learning benefits, an experiment was carried out in two replications. The subjects were 80 students enrolled in General Microbiology at Wallace Community College, Alabama. Students were randomly assigned to experimental and control groups. The…

The Independent Learning Project for Advanced Chemistry (ILPAC) has produced units of study for students in A-level chemistry. Students completing ILPAC units assume a greater responsibility for their own learning and can work, to some extent, at their own pace. By providing guidance, and detailed solutions to exercises in the units, supported by…

This unit on chemical bonding is one of 10 first year units produced by the Independent Learning Project for Advanced Chemistry (ILPAC). The unit, which consists of two levels, provides an introduction to the main types of chemical bonding and important aspects of structure. The main emphasis is placed on such topics as ionic and covalent bonding,…

This unit on the gaseous state is one of 10 first year units produced by the Independent Learning Project for Advanced Chemistry (ILPAC). The unit consists of two levels. Level one deals with the distinctive characteristics of gases, then considers the gas laws, in particular the ideal gas equation and its applications. Level two concentrates on…

Presented are descriptions (with photographs) of demonstration equipment purchased, assembled, developed, and used at William Jewell College (Missouri) during the past 25 years. The descriptions are organized into the following topic areas: (1) mechanics; (2) heat; (3) waves, sound, and acoustics; (4) electricity; (5) optics; and (6) atomic and…

This guide, the second in a series of three, provides the Spanish-speaking intermediate science student and teacher an opportunity to review selected science concepts and processes through activities which emphasize the applicability of scientific knowledge in the professional world. This guide is divided into three components. The first component…

Microcomputers can perform two distinct functions in high school science classes, providing computer-assisted instruction and serving as tools in experimentation. This report describes a project based on three premises: that science is primarily the process of examining, modeling, and understanding nature; that the best way to learn science is by…

A joint business-chemistry course which focuses on consumer testing is described. Guidelines for organizing the students into testing teams and suggested laboratory experiments are included. (DT)

Discusses the use of rubberbands, an empty wooden thread spool, two wooden matches, a wax washer, and a small nail to conduct an experiment or demonstration in powerplant design. Detailed procedures and suggested activities are included. (CC)

A project was undertaken in 1970-76 whose principal purpose was to study the prospects of two-way communication between an administrative authority (the office of the chancellor of the Swedish universities) and the general public (prospective students in the national plan for wider admissions). It grew out of criticism of a proposed national…

Four sections of introductory psychology were involved in a study of aptitude-treatment interactions. Two sections were taught with a high-structure curriculum, and two with a low-structure curriculum. Students' preference for structure was measured with the Inventory of Beliefs (IOB). During eight weeks of instruction, observers recorded…
