The idea that there was a need for formal study of the methods by which titles are selected for addition to the collections of academic science libraries resulted in this investigation of the selection processes of these libraries. Specifically, the study concentrates on the selection procedures in three sciences: biology, chemistry, and physics.…

This volume is the first in a series of the ACS "Modern Chemical Technology" (ChemTeC) curriculum which is to prepare chemical technicians. The chapters concentrate on gas chromatography, tests for purity, properties of gases, and gas measurements. Included is the appropriate content, exercises, laboratory activities, and all needed mathematics.…

Presented are five procedures which permit the effective teaching of chromatography with equipment which is readily available, economical, and simple in design. The first procedure involves a study of solute partition in two immiscible solvents and of countercurrent distribution. The second illustrates the use of unidimensional ascending paper…

The chemical coding scheme of the Medical Coding Scheme (MCS), developed for use in the Comparative Systems Laboratory (CSL), is outlined and evaluated in this report. The chemical coding scheme provides a classification scheme and encoding method for drugs and chemical terms. Using the scheme complicated chemical structures may be expressed…

The purpose of the survey was to collect data relating to (1) present usage of chemical information and data in the Federal community; (2) techniques and equipment now used in the acquisition, processing, and transmission of information and data; and (3) direction of plans for future chemical information services at ongoing systems. The scope of…

The Grade 7 Science course of study was prepared in two parallel forms. A short form designed for students who had achieved a high measure of success in previous science courses; the long form for those who have not been able to maintain the pace. Both forms contain similar content. The Grade 7 guide is the first in a three-year sequence for…

Compared were performances on the Chemical Education Materials Study (CHEMS) semester achievement test of students who were classified on the basis of a specially developed cognitive preference test. Preferences represented in the test were (1) memory of specific facts or terms, (2) practical application, (3) critical questioning of information,…

The purpose of this study was to develop and to evaluate a two-year unified chemistry-physics course at the secondary-school level. Tenth- and eleventh-grade students were placed into experimental and control groups by random sampling with respect to sex and grade level. The experimental and control groups each consisted of 24 students. The…

This unit of instruction presents some important and interesting processes carried on daily in industry and which result in products with which the student is familiar. The student will be responsible for learning some reactions involving these chemical processes and the quantitative calculations of these reactions. Fractional distillation,…

Reported is a discussion concerning the effect of different analyses of the same empirical data. Students (N=over 200) enrolled in an introductory college chemistry course for science majors were randomly assigned to two experimental treatments. Treatment O was designed to help students understand the objectives of the course and to emphasize the…

These proceedings of a 1965 conference on the teaching of science in the sixth form of English schools contain summaries of each speaker's introduction to his paper, the full text of his circulated paper, and a summary of the discussion that followed. The papers were titled the sixth form; "Structure and Properties of Matter" as a sixth…

This study was conducted to obtain educational background information of secondary school students who take the College Board Chemistry Achievement Test. In 1965-66, data were gathered from 49,752 students who took the CEEB Chemistry Achievement Test. Questionnaires from 2,395 of these students were studied primarily for (1) the types of chemistry…

Common concern for the protection and improvement of the environment and the enhancement of human health and welfare underscore the purpose of this special report on the hazards of mercury directed to the Secretary's Pesticide Advisory Committee, Department of Health, Education, and Welfare. The report summarizes the findings of a ten-member study…

This booklet is part of the "Understanding the Atom Series," though it is a later edition and not included in the original set of 51 booklets. A basic survey of the principles of nuclear energy and most important applications are provided. These major topics are examined: matter has molecules and atoms, the atom has electrons, the nucleus,…

Grade 10 students using the Chemical Bond Approach (CBA) materials in a typical classroom setting with large group instruction were compared with students in an "individualized" class using a laboratory-centered, self-paced approach. Both groups were initially comparable with respect to grade nine scores on the "Iowa Test of…
