The effectiveness of a Keller and Bloom mastery learning program for high school science students was examined by comparing remediation strategies of both programs and that of a traditional strategy. The data gathered in the experiment in chemistry were from a pre- and post-achievement test. Cognitive achievement was statistically different (p…

Five elements are identified as being potentially hazardous in this module. These are boron, cadmium, copper, molybdenum, and nickel. The hazards to plants and animals posed by these elements are discussed in some detail. The sources of toxic elements in sewage and the factors that effect the uptake of toxic elements by sewage sludge are also…

This module expands on the introductory discussion of nitrogen in other modules. The various chemical forms of nitrogen found in land treatment systems are defined. Inputs from waste application as well as natural sources are quantified for typical situations. A discussion of nitrogen transformations in the soil includes mineralization and…

This manual introduces teachers to the biological systems at work in a marine aquarium. It provides guidance in selection of the tanks, specifically discussing the effect of capacity on the well-being of the occupants. It guides the teacher in setting up aeration, filtering, lighting, and temperature control for the aquarium. It also advises on…

This review is intended to assess available literature in order to define the range of nitrate/nitrite effects on animals. Though the literature deals primarily with livestock and experimental animals, much of the contemporary research is concerned with human nitrite intoxication. Thus, the effects on man are discussed where appropriate. Some of…

This publication is a handbook used in conjunction with the course of study in chemistry developed through the New York State Education Department and The University of the State of New York. It contains experiments, demonstrations, and other activities for a chemistry course. Areas covered include the science of chemistry, the atomic structure of…

The main objective of this study was to design an instrument to assess the value preferences of college non-science majors with respect to certain aspects of environmental chemistry. A second objective was to obtain measures of the value preferences of various groups of non-science majors who had completed some chemistry courses. The early…

This paper provides a broad reexamination of the correlates of faculty age, incorporating several measures of research activity and other related professional achievement variables. The data are derived from a large-scale, nationally representative survey of college and university faculty members; analyses are based on a subsample of all doctorate…

Described is a method by which a classroom teacher may apply the systems approach to the development of the instructional segments which he uses in his daily teaching activities. The author proposes a three-dimensional curriculum design model and discusses its main features. The basic points which characterize the application of the systems…

The design, implementation and operation of the Computer Search Center of IIT Research Institute, an information center to educate and link industry and academic institutions to chemical and other scientific information systems, is described. Format conversion, profile input, search and output programs developed over a two-year period are detailed…

Contained are guidelines and an extensive list of books and journals suitable for an undergraduate chemistry library. The guidelines are concerned with the organization and acquisition policy of chemistry libraries, and with inter-library loan and photoduplication services. Various sections of the report deal with journals and abstracts, review…

In order to ascertain the effectiveness of programed instruction as compared to teacher instruction and to evaluate the quality of classroom research by teachers, the Canadian Teachers' Federation offered ten instruction programs on mathematics and chemistry to teachers throughout the country and asked them to evaluate the effectiveness of the…

This report gives examples of diverse educational strategies in science and engineering education to illustrate the capabilities of the PLATO III computer-based education system. The basic structure of the TUTOR language is discussed and some technical details are given to explain how the PLATO III system works. A brief description of the…

The topics covered by 47 booklets in the series are indexed. Page references are not given, but the booklet covering each topic is indicated by a code explained in the first two pages of the index. A brief account of the educational services program of the Atomic Energy Commission describing the booklets, films, and other services provided for…

The project which resulted in this report was a study of decision making in the selection of science library materials in college and university libraries. Questionnaires, interviews and objective collection descriptions were used to collect information in the fields of chemistry, physics and biology. Part I is an analytic description of the…
