This resource guide was prepared to offer teachers and supervisors practical suggestions for the teaching of science to the pupils in the Career Guidance Program. The material presented parallels, as closely as possible, the regular science program for grade nine. However, many of the basic concepts and skills were drawn from the seventh year and…

This building program statement for the new chemistry addition at Purdue University was compiled to provide the architect and development planning personnel with information about academic specifications that could be used as a basis for designing a new chemistry facility. The general plan is based on projected student enrollment. Specific plans…

This project consisted of the design, trial use, and evaluation of instructional procedures designed to reduce the amount of routine information given directly to the students by the instructor in chemistry laboratory courses for college freshmen. Printed materials gave the student a decision-making role in planning his laboratory work. Tape-slide…

The effectiveness of microteaching techniques for improving presentation of science demonstrations by perspective science teachers was investigated. Three groups of students of ten members each were randomly selected from professional education courses for science teachers. Group A students presented two trials of two different demonstrations.…

This is the National Science Teachers Association project report regarding curriculum development in science. The approach utilizes conceptual schemes as basic elements. The theoretical base for this approach is developed in detail, and the implications for the classroom teacher are carefully analyzed. Guidelines for implementing a curriculum…

Parts I and II of the students' guide to the three-year integrated biology, chemistry, and physics course being prepared by the Portland Project Committee are contained in this guide. A committee reviewed and selected material developed by the national course improvement groups--Physical Science Study Committee, Chemical Bond Approach, Chemical…

This paper discusses several inexpensive methods of evaluating the salinity of seawater. One method is presented in some detail. This method has several attractive features. First, it can be used to provide instruction, not only in marine chemistry, but also in studying the mathematics of the point slope formula, and as an aid in teaching students…

Details of a computer-assisted instruction program in chemistry are given. Approximately half of the instructional computer usage is centered around drill, tutorial, and simulation programs. Problem solving, including research, and programming courses constitute the other half. Also described is a computerized system available to the chemistry…

This publication is the fifth in a series of seven supplementary investigative materials for use in secondary science classes providing up-to-date research-related investigations. This unit is structured for grade levels 9 through 12. It is concerned with the removal of heavy divalent metals from water with the use of tannin-containing…

This publication is the sixth of a series of seven supplementary investigative materials for use in secondary science classes providing up-to-date research-related investigations. This unit is structured for grade levels 10 through 12. It is concerned with the crystallization of an enzyme, lysozyme, from egg white. The first part of this guide…

This module introduces the physical, biological, and chemical constituents of wastewaters and sludges which are of concern in land treatment systems. The characteristics of typical municipal wastewater are tabulated for strong, medium, and weak sewages. Some of the factors affecting pollutant concentrations are listed. Flow, distribution and…

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,…
