The purpose of this study was to compare the affective behavior of students enrolled in the various high school science courses. The sample for the study included eight science courses. The sample for the study included eight science classes consisting of the following: 45 ninth-grade Introductory Physical Science students, 46 tenth-grade biology…

A screening study was conducted to evaluate the capability of aqueous solutions to scrub NOx from the flue gases emitted by stationary power plants fired with fossil fuels. The report summarizes the findings of this laboratory program. The experimental program studied the following media for absorption of NOx from flue gases containing no NOx:…

A prototype model low level carbon monoxide analyzer was developed using fluorescent cell and negative chopping techniques to achieve a device superior to state of art NDIR (Nondispersive infrared) analyzers in stability and cross-sensitivity to other gaseous species. It is clear that this type of analyzer has that capacity. The prototype…

Differing somewhat in format from the previous three volumes of this series, this work contains analyses of trends and problems in various aspects of chemistry instruction as presented by authors from around the world, but is printed entirely in English. Materials for this publication resulted from a UNESCO organized International Congress on the…

This booklet is a teacher's manual in a series of booklets that make up the core of a Physical Science course designed for the freshman year of college and used by teachers in the 27 colleges participating in the Thirteen College Curriculum Program. This program is a curriculum revision project in support of 13 predominantly Negro colleges and…

In this study a training program for new teaching assistants in freshman chemistry was developed and assessed. All new assistants in the Freshman Division were assigned by a stratified random technique to either the control or treatment group, with the latter receiving inservice training in the skills of teaching recitation classes. This training…

Presented is a summary of some of the available literature in which emphasis is placed on the mathematical skills required for science courses presented on the high school level. A considerable emphasis is placed on the skills required for a high school physics course. The author concludes that, in general, measures of quantitative ability are…

The well known Saltzman method for oxides of nitrogen is intended for the determination of these constituents in the ambient atmosphere in the range of a few parts per billion to about 5ppm. However, when sulfur dioxide is present in the gas to be sampled and/or the concentration range of the oxides of nitrogen is from five to several thousand…

The CHEM Study literature reviewed consists of (1) the "subjective" literature, as evidenced by project newsletters, position papers, and open sources and (2) the "objective" literature, which consists of research studies related to CHEM Study. The "subjective" literature provides many suggestions regarding the use of…

Critical incidents were used to collect faculty ratings of graduate student performance in the departments of chemistry, English, and psychology. Separate factor analyses in each of three fields produced eight factors that were fairly consistent with respect to item loadings across fields. Factors were labeled independence and initiative,…

The Mathematics Skill Test (MAST) is a test designed to show a student's 10-skill profile of mathematics competencies deemed necessary for success in high school chemistry. It was administered in May to tenth-grade students at two schools. On the basis of the results, students were enrolled for advanced or regular chemistry, or were advised to…

This study investigated the mathematical skills required for high school chemistry. Ten skills were identified from an analysis of recently-published tests. Items testing these skills in three operationally defined levels of difficulty were first written and validated by a panel of experts. The 91-item preliminary form of the Mathematics Skill…

In this third volume of the United Nations Educational, Scientific and Cultural Organization's (UNESCO) series on "New Trends in Chemistry Teaching," a total of 29 papers originally published during the period from 1969 to 1971 in leading chemistry-teaching periodicals of the world is compiled for the purpose of promoting information exchange. The…

A complete organic gardening cycle--from soil composition to harvesting--can be conducted using the 14 activities suggested in this teacher's guide. Background information, questions for discussion, and related activities are presented for each step in the process. The activities, useful for elementary grade students, are titled: Starting the…

The United States Training and Employment Service General Aptitude Test Battery (GATB), first published in 1947, has been included in a continuing program of research to validate the tests against success in many different occupations. The GATB consists of 12 tests which measure nine aptitudes: General Learning Ability; Verbal Aptitude; Numerical…
