Seven activities are included in this 10 day secondary school science unit in which students determine the effect that auto exhaust fumes have on the air they breathe by utilizing laboratory experiences, independent research, and in-class discussions. Rationale, objectives, and instructional strategies are provided for each activity. Following two…

This research study was conducted to investigate the interactions of specific student aptitudes with their ability to solve chemistry problems of varying structure and information. Fourteen classroom quizzes were validated and a number of in-task variables were identified for analysis. These variables included: the nature of information given…

To develop practical Web-based instruction (WBI) design guidelines for faculty and instructional support staff, the author analyzed three different WBI design cases based on interviews with three experts. On the surface, the WBI design processes that each expert used look more alike than different, entailing similar major steps. The underlying…

An interim status report is presented on a study of predictors to aid in reducing the 35-40% dropout/failure rate in general chemistry at the Mississippi Gulf Coast Junior College, Perkinston Campus. Data from 1974-75 and 1975-76 were used to develop a formula whereby potentially weak students could be identified before they failed or dropped out…

Since the major causes of accidents are carelessness and a negative or apathetic attitude towards safety, this guide was developed to facilitate safe, stimulating science laboratory activities by providing both general and specific safety information presented in 12 sections. Subject areas considered in these sections include: 1)…

This unit introduces analytic solutions of ordinary differential equations. The objective is to enable the student to decide whether a given function solves a given differential equation. Examples of problems from biology and chemistry are covered. Problem sets, quizzes, and a model exam are included, and answers to all items are provided. The…

This directory provides information on research in chemistry at private undergraduate colleges. A department profile and a faculty profile are provided for 123 colleges. The department profile is designed to provide information on the available human resources, facilities, and financial support. The human resources section consists of data on the…

Compiled as an immediate source of reference and guidance, this manual was published by the Scottish Schools Science Equipment Research Centre to provide the following information about alphabetically listed chemicals considered to be hazardous: (1) the hazards; (2) incompatibility with other agents; (3) methods for handling, storage, disposal and…

This document reports results of two applications of an alternative cost model to two-year college education programs. Purpose of the study was to identify nonoperational costs (costs other than instruction) that are not usually found in financial reports. Current educational cost practices report costs by jurisdictional units; the way costs are…

INFORMATION ON RECENT CURRICULUM REVISIONS IN ELEMENTARY AND SECONDARY SCIENCE IS PRESENTED. THE CHAPTERS INCLUDE MATERIALS FROM PAPERS THAT WERE PRESENTED AT NINE REGIONAL CONFERENCES OF THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE. THE INTRODUCTORY CHAPTER RELATES CURRICULUM MODIFICATION TO CHANGING SOCIAL STRUCTURE AND CONCOMITANT…

GROWING COLLEGE ENROLLMENTS HAVE BEEN ACCOMPANIED BY SIMILAR INCREASES IN DEMAND FOR GENERAL CHEMISTRY, WITH RESULTANT PROBLEMS OF MAINTAINING QUALITY OF INSTRUCTION. THIS PAPER IS A DISCUSSION OF SOME WAYS OF MEETING THE PROBLEMS OF NUMBERS. MULTISECTION COURSES MAY BE ORGANIZED AROUND COMMON GENERAL OBJECTIVES OR AROUND COMMON CONTENT. AN…

A STUDY WAS INITIATED IN 12 SECONDARY SCHOOLS TO INVESTIGATE THE EFFECTIVENESS OF FILMED CHEMISTRY AND PHYSICS COURSES. CONTROL VARIABLES WERE USED TO INSURE COMPARABILITY OF EXPERIMENTAL AND CONTROL GROUPS. ACHIEVEMENT, INTEREST, AND ATTITUDE SERVED AS THE STANDARDS BY WHICH THE EFFECTIVENESS OF THE FILMED COURSES WERE JUDGED. BOTH GROUPS WERE…

A directory, sponsored by the Council on Undergraduate Research, provides information on research in chemistry at private undergraduate colleges. A department profile and a faculty profile are provided for 93 colleges. The department profile is designed to provide information on the available human resources, facilities, and financial support. The…

Designed to accompany the student text on respiration, this manual presents instructions on the use of laboratory equipment and presents various experiments dealing with the concepts presented in the text. Thirty-nine laboratory activities are described. Laboratory activities are divided into several parts, each part covering a specific experiment…
