The effect of self-grading on biology students exposed to the same instruction (except grading) in an upper-middle class public school was investigated by comparing self-graded and teacher-graded populations in (1) achievement in high school biology, (2) level of aspiration behavior, (3) critical thinking skills, and (4) productivity. The…

A model demonstrating the relationship between the structure of blood vessels and the flow of blood is described and illustrated in the biology section of the newsletter. The apparatus also contains a functional (but not structural) model of the heart. Suggestions for the preparation of a relatively permanent dialysis bag from visking tubing are…

This paper describes a physics course at Eastridge High School in Rochester, New York, which is highly adaptable to a variety of student interests and needs. Three content streams in Physical Science Study Committee (PSSC), Project Physics and New York State Regents physics are contained in one course. Individual materials for all three streams…

This guidebook contains designs of laboratory equipment considered essential for student investigations in introductory biology in developing countries. The designs presented are based on the premise that many students and teachers will wish to make equipment for themselves. Although all the designs have been tested under laboratory conditions at…

This issue of the Biological Sciences Curriculum Study (BSCS) newsletter is mainly devoted to reports of the international adaptation of the BSCS materials. The BSCS director provides an overview of the international cooperation program, and a member from most of the adaptation teams contributes a short report on the progress of adaptations in his…

This instructional package contains three animal life units developed for the Dade County Florida Quinmester Program. "The World of Animals" is a survey course of the animal kingdom (excluding man) and involves the students in many laboratory investigations and group activities. Typical animals of South Florida and unusual animals of the…

This instructional package contains two biological units developed for the Dade County Florida Quinmester Program. "Introduction to Life Sciences" develops student understandings of cell structure and function, and compares different levels of cellular organization. "Cell Biology" investigates the origin of modern cellular…

AN ANALYSIS OF THE STATUS OF HIGH SCHOOL PHYSICS AND THE QUALIFICATIONS OF INSERVICE AND NEW PHYSICS TEACHERS IN NORTH CAROLINA IS PRESENTED. ALL SECONDARY SCHOOLS IN THE STATE WERE INCLUDED IN THE SURVEY. A RANDOM SAMPLE OF 88 TEACHERS WAS SELECTED FOR THE ANALYSIS OF THE QUALIFICATIONS OF PHYSICS TEACHERS. DATA WERE OBTAINED FROM THE BIENNIAL…

Provides a brief account of the discovery and theory of antimatter and describes several activities relevant to the study of antimatter on the secondary level. (MLH)

Discussion on the proper use of the chemistry terms "dissociation, hydrolysis, ionization, oxidation and reduction" is presented. (CP)

Examines Piaget's theory of cognitive development with particular reference to the teaching of chemistry in the secondary school. Concludes that the theory has many fundamental weaknesses, with respect to analyzing curriculum materials in terms of levels of thought and should not be used as the basis for course assessment. (GA)

Reviews chemical education in English secondary schools from 1899 to date. (SL)

Last in a series, this article focuses on reporting and using the outcomes of the examination for the Nuffield Advanced Chemistry Project. Discusses accuracy, reliability and validity estimates, and curriculum validity; provides detailed information about student attainment.
