This module is designed to help students: (1) describe a way of tapping solar energy; (2) identify the main parts of a box type solar cooker; (3) describe how each part contributes to the trapping of heat energy in the cooker; (4) cook some food in a solar cooker; and (5) recognize that food cooked in a solar cooker is safe to eat. It includes: an…

This module: (1) discusses the need for disposing of waste safely; (2) provides information and activities on wet and dry wastes; and (3) shows how to prepare, maintain, and study a fertilizer basket (in which fertilizer is made from wet waste). Information on the biology of the basket (including role of bacteria and fungi in the decay process) is…

This study tested the hypothesis that the relationship between self-image and achievement would show different developmental patterns for boys and girls, particularly with regard to the relationship between self-image and mathematics and science achievement. Subjects were selected from two successive sixth grade cohorts in two predominantly white,…

Preliminary results from a study of students' conceptions in introductory rotational physics are discussed. Analyses of data from problem solving interviews and written diagnostic tests provided evidence that many students had a poor qualitative understanding of torque. Even among students who answered questions correctly a percentage did so for…

This booklet is a compilation of factual information about physics education in Great Britain. It is an update of a previous booklet of the same title dated 1979. Almost all of the information is presented in graphical or diagrammatic form. Data are usually given for a few subjects in addition to physics to permit comparisons. Separate data for…

In this study, the attitudes of Israeli children aged 6 to 15 years were surveyed regarding their conceptions of plants as living things. It was desired to find out whether children consider plants to be alive, the knowledge differences between the different age groups in the study, how children classify plants according to biological criteria and…

The five papers in this set describe a research program designed to examine how an intended science curriculum, as described in policy documents and textbooks, is interpreted by teachers and adapted to an established pattern of classroom functioning embodied in what is called a "functional paradigm." The overall objective of the research is to…

In the 20 years since the inauguraion of "Jugend forscht" (Young Researchers) over 26,000 boys and girls have taken part in this annual Olympiad of young innovators. This brochure gives an insight into the diversity of themes dealt with by the "Jufos" (young researchers) and into their ability to achieve astonishing…

A number of recent policies have tried to improve science learning by increasing the number of science courses required for high school graduation or admission to higher education institutions. But it is highly unlikely that these mandates alone will materially affect the amount and quality of science education for students. Any effort to improve…

This resource guide has been prepared to help high school personnel infuse energy education into the basic education program of grades 10-12. The resource guide has two major sections. The first deals with the "why, what, when and where" questions of energy education including a set of objectives and concepts relative to energy education at the…

This guide focuses on the content and methodological approaches useful in teaching basic and applied science courses from a feminist perspective. Course content and pedagogical methods for including the feminist perspective are discussed for different curricula, including biology, women's studies, and health. A discussion of approaches for…

The North Carolina End-of-Course Testing Program was established to provide student, school, and school system information about achievement in high school courses. Approximately 83.4 percent of the 77,154 students who took the biology test were in the tenth grade. Students taking biology in the ninth grade (8.3 percent) were on an accelerated…

During a time when the values in society are changing, knowledge is rapidly expanding, technology is changing, and the use of science and technology is increasing, there is a need to review the role and nature of a biology program for the schools. Such a review was conducted by the K-12 Science Working Party of the Manitoba Department of…

Kudzu (Pueraria lobata) is a high climbing, exceedingly vigorous vine with twining stems (no tendrils or aerial holdfasts). The plant, introduced from the Orient and currently found in southeastern United States, has been known to choke valuable strands of trees, short electrical wires, and even creep up the sides of high rise buildings. Although…

This unit on the mole is one of 10 first year units produced by the Independent Learning Project for Advanced Chemistry (ILPAC). The unit, designed to help students consolidate some of the ideas about the mole learned in previous courses, consists of two levels. The first level focuses on: (1) relative mass; (2) the concept of the mole as the unit…
