The focus is on the formulation and solution of mathematical models with the idea of a population employed mainly as a pedogogical tool. If the biological setting is stripped away, the material can be interpreted as topics or the qualitative behavior of differential and difference equations. The first group of models investigate the dynamics of a…

Fossil fuels, upon which we now depend almost exclusively, are finite resources. Because the environmental problems inherent in large scale fossil fuel consumption are increasingly apparent, the reality of developing alternative energy sources must be faced. Solar energy is the obvious solution to the problem. It is a renewable, clean source that…

COMETS Science (Career Oriented Modules to Explore Topics in Science) was developed to demonstrate to early adolescents that learning mathematics and science concepts can have payoff in a wide variety of careers and to encourage early adolescent students (grades 5-9), especially girls, to consider science-related careers. The program provides 24…

This set of nine papers on special library concerns includes papers presented by participants from Canada, Denmark, East Germany, the United States, and the United Kingdom. Papers are entitled: "The Needs of the Special Librarian and the Library Association," by Miriam H. Tees; "Position and Development of Special Libraries within…

The relative percentages of males and females in illustrations were identified in a select sample of children's science trade books. The books chosen for analysis were the "Outstanding Trade Books for Children 1979." These books were selected as outstanding children's science trade books mainly for grades K-8 and were evaluated by a…

This study provides information about the biology and life science classroom teaching environments in Southern Alberta. Responses (N=53) to questionnaires sent to junior and senior high school teachers in rural and urban settings revealed information regarding school facilities, texts and reference materials, field trips, outdoor education…

This is the second of a two-part review of instructional procedures in secondary school science. Analyzed are research studies in the field mainly over the period 1960-67. Studies were reviewed under the following headings: team teaching, programed instruction, audiovisual aids, laboratory procedures, extra classroom activities and field…

REPORTED IS THE DETERMINATION OF THE RELATIVE EFFECTIVENESS OF THREE LEVELS OF ABSTRACTION (VERBAL, SKETCH, MECHANICAL MODEL) IN THE USE OF THE CONCEPTUAL SCHEME OF EQUILIBRIUM AS AN ADVANCED ORGANIZER APPLIED TO INSTRUCTION WITH REFERENCE TO ECOLOGICAL SYSTEMS. LESSONS WERE TELEVISED TO CONTROL THE INSTRUCTION OF PUPILS IN GRADES 7 AND 9. THE…

A batch-mode, computer-based, serials system was developed for the bio-medical library, a departmental library at the University of Minnesota. Patterned after the "arrival card" system now in use in several libraries, it is designed so that serial check-in is done by marking off the issue on a printed list of serial issues expected…

The genetics of mental retardation are discussed in terms of geographical isolates, prospects for prevention of trisomic conditions, population genetics, and cytogenetics of Down's syndrome; problems of neurogenesis described are anabolic pathways of galactose and glucose metabolism, abnormal cell migrations in developing brains, and genetic…

This document provides science curriculum instructional material relating to marine biology. Items presented relate to live animal exhibits seen during visits to Sea World marine aquarium exhibits; however, all materials are also useful for in-class instruction without visits to Sea World displays. Ideally, material should be reviewed immediately…

This publication is a collection of science activities designed to enrich elementary or junior high science curricula. These activities encourage students to investigate facets of life sciences, physical sciences, and earth sciences either with a teacher or independently. The 70 activities have been classified into 10 subareas under these three…

The life science curriculum is designed to promote the development of healthy living habits. Emphasis is placed on problems of major concern in the daily life of students and on significant problems in modern society. The curriculum is designed for students enrolled in the coordinated vocational education and training for disadvantaged and…

Questionnaires were sent to all of the medical, dental, veterinary, and public health schools in the United States and to selected degree-granting U.S. schools of nursing, medical technology, and pharmacy. The data collected included type of biological prerequisites for each school and role of preparatory courses in the admissions policy. A…
