Speech pathology and linguistics have, as sciences, experienced a parallel development over the past fifty years. Although these disciplines have traditionally been separated, they have common areas of concern, and there are indications of a growing interest on the part of speech pathologists in such linguistic subfields as sociolinguistics,…

Presented is a collection of thoroughly-tested discrepant events designed for use in science classes. These events have been organized into 17 chapters grouped into four sections: Environment (5 chapters), Energy (7 chapters), Forces and Motion on Earth and in Space (3 chapters), and Living Things (2 chapters). The following information is…

Results of a study that examined entry competency levels of 1,511 students enrolled in 12 sections of introductory biology at Texas A&M University are reported. A pretest was developed and administered to students which tested basic competencies over nine concept areas considered prerequisite to the introductory biology course. A questionnaire…

The author of this booklet is an engineer who conducts experiments in solar energy. Here he has described basic principles of the field. He also details methods of constructing a variety of solar implements, including solar panels, solar cells, a concentrating collector and a solar furnace. The book is intended for the layman and contains…

This study assessed the construct validity of a cognitive structure interpretation of multidimensional scaling solutions of concept similarity data. Using high school subjects, convergent validity was assessed through correspondence of scaling solutions of three similarity rating tasks; word association, similarity judgment, and semantic…

This guide is designed to help elementary classroom teachers develop the knowledge and skills necessary to bring process skills to the classroom. The text is presented in two parts. The first part covers the basic science skills which are intended for grades K-3. The basic skills are observing, inferring, measuring, communicating, classifying and…

Reported is a study designed to evaluate differences in cognitive processes related to science among (1) college bound high school students who had studied both physics and chemistry, (2) college bound students who had not studied either subject, and (3) non-college bound students who had not studied either subject. The test used to assess the…

The relationships among the three dominant means of education in American society and the development of utopian thought are examined. The author defines the three forms of education as the scientific, the entropic, and the metaphysical. The scientific form pursues knowledge through rigorous empirical verification, while the metaphysical form…

The fifth annual report of Harvard University's Program on Technology and Society describes current research in the Program's major areas of concentration--namely the effects of technological change on the life of the individual in society, social and individual values, the political organization of society, and the structure and processes of…

At the Massachusetts Institute of Technology, a 4-year project was undertaken to restructure the sophomore elective course in social science for natural science and engineering students. The restructured course emphasized an objective, rigorous, and exact approach to social phenomena. Readings were designed to carry the student step by step from…

Discusses three current approaches to curriculum for science education which seem to be converging on a similar model for instruction: technology and society; misconceptions in science; and hands on science. The technologies required for the implementation of this teaching model are identified, and appropriate science education resources are…

Describes the nature of elementary particles, quarks, leptons, and bosons. Indicates the possibility of a fourth family of quarks. Predicts the nature of the lepton relatives. (YP)

Reviews two computer software packages for use in physical science, physics, and chemistry classes. Includes "Physics of Model Rocketry" for Apple II, and "Black Box" for Apple II and IBM compatible computers. "Black Box" is designed to help students understand the concept of indirect evidence. (CW)

Discusses some of the drawbacks of using a demonstration of the electrolysis of water to illustrate the interconversion between electrical and chemical energy. Illustrates a simple apparatus allowing demonstration of this concept while overcoming these drawbacks. (CW)

Critiques the "energy circus," an approach to the introduction of ideas of energy transformation and conservation which is in common use in secondary schools. Identifies some practical and conceptual difficulties and outlines an alternative approach used in introducing ideas about energy using real devices and arrow notation. (CW)
