The purpose of this study was to show that societal problems such as energy and pollution should be included as a central and underlying theme in a college chemistry course. A questionnaire was administered to 156 college students in science and technology to determine whether the students felt that they would be more highly motivated in chemistry…

This document is an instructional module package prepared in objective form for use by an instructor familiar with analytical procedures for determining ammonia nitrogen concentrations in a water or wastewater sample. Included are objectives, instructor guides, student handouts, and transparency masters. This module considers preliminary…

This document is an instructional module package prepared in objective form for use by an instructor familiar with standard method procedures for determining the Chemical Oxygen Demand (COD) of a wastewater sample. Included are objectives, instructor guides, student handouts, and transparency masters. This module considers analytical procedures,…

This document is an instructional module package prepared in objective form for use by an instructor familiar with the laboratory procedures for determining the combined chlorine residual of a wastewater sample. Included are objectives, instructor guides, student handouts, and transparency masters. This module considers the amperometric, DPD,…

This document describes an introduction course in the fundamentals of chemistry for marine engineers. The course is modularized, audio tutorial allowing the student to progress at his own rate while integrating laboratory and lecture materials. (SL)

Five randomly selected experimental groups of twenty-four general college chemistry students participated in this study. Four of the five groups received a version of the systems approach treatment, which consisted of group orientation, individualized learning, small group seminars and unit tests. The fifth group was administered the traditional…

The value orientations of 39 chemistry teachers and their 120 students were measured and compared to the theoretical, humanistic, and technological aspects of chemistry. A Chemistry Preference Evaluation Instrument containing alternative statements concerning these three aspects was administered to teachers and students. The reliability…

A computer program for the simulation of complex continuous process in real-time in an interactive mode is described. The program is user oriented, flexible, and provides both numerical and graphic output. The program has been used in classroom teaching and computer aided design. Typical input and output are illustrated for a sample problem to…

This study investigated the long term effects of the Personalized System of Instruction (PSI) method at the University of California, San Diego. Groups of 139 and 137 undergraduate students took three physics courses taught by either the PSI method or the lecture/discussion method. Students from these groups were compared in two subsequent…

The purpose of this study was to compare two systems of teaching basic college chemistry. Three regression equations were developed for predicting a student's total raw score on the various tests used. The covariates utilized were ACT composite scores and scores on the Watson-Glaser Critical Thinking Appraisal, given as a pre-test. There was no…

This study was designed to identify patterns of selections and performance characteristics displayed by individuals during a concept-attainment task. The relationships between selection patterns and individual characteristics were studied in addition to the effects of changes in task characteristics on selection patterns. The population was 200…

The report represents the efforts of two schools of higher education in northern Wisconsin to keep Lake Superior, the largest surface area, fresh water lake in the world, close to the condition it was in thousands of years ago when it was formed. The University of Wisconsin-Superior and Northland College have been studying, since 1972, water…

The study involved the development, implementation and evaluation of laboratory audio-tutorial activities in a college chemistry course. The activities were designed in a self-instructional mode, written as linear programs and taped instructions. A pretest was used in two instances, but all included a posttest. To evaluate the effectiveness of the…

This volume contains chapters 19 to 25 of the ACS "Modern Chemical Technology" (CHemTeC) curriculum material which is intended to prepare chemical technologists. Laboratory techniques and procedures are emphasized. The chapters cover the areas of the techniques of sampling, the techniques of weighing, sample preparation, the measurement of pH,…
