Reported is a study focused on the construction and development of a model for guiding science curricula developers in designing the needed second generation programs for non-science secondary students in the seventies. The Technology (and Science) for Social Action Curriculum (TSAC) is presented as illustrative of the problems involved in…

Presented is one of a series of National Aeronautics and Space Administration (NASA) facts about the exploration of Mars. In this publication, emphasis is placed on the sun's planetary system with note made that there is no one theory for the origin and subsequent evolution of the Solar System that is generally accepted. Ideas from many scientists…

This book discusses how some of the topics taught in a conventional physics course have been used to solve interesting technical problems in industry, medicine, agriculture, transportation, and other areas of society. The topics include heat, optics, magnetism and electricity, nuclear physics, and sound. (MLH)

The purpose of this study was to obtain empirical data for the evaluation of a team approach for teaching biology. A sample of 147 sophomore students was divided into six sections; each section was randomly assigned as control or treatment. The team consisted of three instructors. Each member taught a control group for an entire year. After an…

Fundamental concepts of motion are presented in this first unit of the Project Physics textbook. Descriptions of motion are made in connection with speeds, accelerations, and their graphical representation. Free-fall bodies are analyzed by using Aristotle's theory and Galileo's work. Dynamics aspects are discussed with a background of mass, force,…

This programmed instruction booklet is an interim version of instructional materials being developed by Harvard Project Physics. It is the first in a series of three booklets on vectors and covers the definitions of vectors and scalars, drawing vector quantities to scale, and negative vectors. For others in this series, see SE 015 550 and SE 015…

This is the second of a series of three programmed instruction booklets on vectors developed by Harvard Project Physics. It covers adding two or more vectors together, and finding a third vector that could be added to two given vectors to make a sum of zero. For other booklets in this series, see SE 015 549 and SE 015 551. (DT)

This is the third of a series of three programmed instruction booklets on vectors developed by Harvard Project Physics. Separating vectors into components and obtaining a vector from its components are the topics covered. For other booklets in this series, see SE 015 549 and SE 015 550. (DT)

This unit was developed to introduce secondary students to the many facets of a typical, large manufacturing plant - the Topeka Goodyear Tire and Rubber Company - in an effort to increase awareness of sound environmental practices in industry. Its five major foci include the production of tires and quality control procedures; applications of…

Two instructional methods were identified and compared to determine if any significant differences could be noted on three criterion measures. Measurements were conducted in the areas of achievement in biology, science attitudes, and critical thinking ability. Student ability was measured using pre-tests and the Scholastic Aptitude Test. Students…

Three ways in which the term "inquiry" is used are discussed: inquiry as a teaching method, inquiry as a mode of learning and inquiry as a logical disciplinary process. The role of guiding principles of inquiry is analyzed, using a discussion of Harvey's work on the heart to illustrate an inquiry guided by the idea of structure-function. It is…

This document includes the introduction to and unit A of "Idea-Centered Laboratory Science" (I-CLS). The introduction describes the objectives, the basic assumptions and suggested teaching procedures of I-CLS. The basic theme of unit A is "How a Scientist Studies His World." Laboratory experiences consist of investigations into: (1) idea of…

Reported is a conference held to develop guidelines for the Australian Science Education Project (ASEP), a national project charged with producing curriculum materials for junior high school science. Included are copies of the addresses given and questions considered by discussion groups, and notes of the findings of the discussion groups.…

These proceedings of a symposium organized by the chemistry department of the University of Maryland contain the texts of addresses given to approximately 200 chemistry teachers and educators from adjacent areas. An outline of the University of Maryland undergraduate chemistry curriculum is given and a summary of discussions between school and…

A 12-category instrument was developed for describing verbal interaction among students working in small groups in the biology laboratory. Seventy-five student laboratory groups were tape recorded. Data were collected while the students worked on two different laboratory activities, and group laboratory reports were collected at the end of each…
