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…

The implications of space science terminology and concepts for elementary science teaching are explored. Twenty-two concepts were identified which elementary and junior high school teachers were invited to introduce in their teaching. Booklets explaining the concepts were distributed together with report forms for teacher feedback. The numbers of…

This book was developed for use in India and is adapted from "Ideas for Science Investigations" by Victor M. Showalter and Irwin L. Slesnick. It is a source book of ideas for student research projects. Three model projects are described, illustrating different approaches taken by three students to the investigation of the rise of sap in…

This manual was prepared for a teacher workshop in marine science. It includes information on when, where, and how to collect marine mollusks, and how to prepare a shell collection; a partial key to the classes, subclasses, and orders of the mollusca; notes on the ecology and physiology of marine bivalves and snails, and recipes for solutions…

Five perspectives are identified for viewing inquiry: "Guiding Principles: (for example the antecedent-consequent principle), Inquiry Factors or logical steps in inquiry, Behavioral Objectives, Affective or Attitudinal Qualities, and Inquiry into Inquiry. Many components of these perspectives are enumerated, together with related student…

Included are two of the eight units of the Intermediate Science Curriculum Study materials designed for grade nine students. These are "investigating variation" and "winds and weather." Introductory notes to the student explain how the book is to be used. Each chapter starts with a short statement of a general problem, then…

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,…

This guide contains factual information about the status of science education in the public, private, and parochial schools of Montgomery County, Pennsylvania. The content reveals an organization of material, grades 6-12, arranged alphabetically by district. The items of information are letter-coded, and a list showing the letter-code and its…

This bulletin includes general directions for assistant principals, science teachers, laboratory specialists, and pupils pertaining to science laboratory safety. A list of hazards and precautions is presented. Also included is a list of chemicals considered dangerous by the New York Fire Department. (DJH)

Contained in this publication are abstracts of the various contributed papers, speeches, concurrent sessions, science seminars, forums, and curbstone clinics of the 22nd annual meeting of the National Science Teachers Association. Materials from the affiliated groups: Association for the Education of Teachers in Science (AETS), Council for…

The author developed three instruments which operationally defined certain probability concepts and combinatorial abilities and subsequently used the instruments to classify the 90 subjects of the study according to their conceptual strategies or ability levels. The subjects were high school biology students from one school; all were taught by the…

Cytology is the subject that is dealt with in this autoinstructional program. The process to be understood by secondary school students who are taking biology is mitosis. The material is presented to be adequate for achievers at the middle level. Knowledge of the structure of the DNA molecule and of the parts of the cell are considered as…

This autoinstructional lesson deals with the study of molecular biology. It is suggested as relevant to high school biology courses. No prerequisites are suggested. Two behavioral objectives are given leading to the learning of nucleotide bases, their parts, and the ways they pair as they do. The time suggested for this learning activity is about…

This unit of instruction deals with a study of human physiology with emphasis on the process of digestion. The urinary system and urinary disorders are also discussed. The course is for the interested student and requires credit or background in previous biology programs. It is, in part, a second course in biology, but it is well within the range…

This unit of instruction deals with a study of South Florida as an ecosystem. Consideration is given to meteorological features, geological foundations, chemical analyses, and biotic communities characteristic of South Florida. A major attribute is the development of monographs about the unique natural wealth of the lower South Florida peninsula.…
