A developmental investigation of the ability to control variables was conducted. One or two logically similar physics problems were individually administered to 120 subjects age 12 to 14. The problems involved either familiar or unfamiliar variables. Each problem was presented in three different informational formats. Success on the problems in…

Four units, teacher's notes, and a comprehensive glossary provide background information and activities aimed at raising the awareness of high school students and teachers regarding the nature of the food system and its relationship to nutrition, population, and resources. These non-sequential units analyze the economic and political factors…

An attempt to train concrete operational fifth-grade students (N=32) and seventh-grade students (N=32) to perform at the formal operational level on tasks demanding the control of variables are reported. The training was conducted in four individual sessions of approximately 30 minutes each. The training sessions were designed to represent a…

The National Science Foundation's (NSF's) institute programs and curriculum development activities are briefly reviewed as well as the current activities of the Information Dissemination for Science program. Included are goals of the program and a discussion of the nature of projects funded by the program. (DS)

Reported are results of a study proposing to determine whether developmental patterns in correlational reasoning could be identified among a large and diverse sample; whether developmental patterns in correlational reasoning were similar regardless of problem context; and whether developmental patterns in correlational reasoning were similar for…

Women Inquire into Science and Engineering (WISE) is a 22 minute audio-visual (slide/tape) program for students in grades six through twelve. Its purpose is: (1) to apprise students of the opportunities for them in the Inquiry Into Science and Engineering Class and encourage them to take the prerequisite math and science courses; and (2) to…

The collection of competency goals and performance indicators is designed to assist regular and special educators in creating curriculum and instructional programs to maximize the learning potential of educable mentally retarded students. The competency goals and performance indicators are identified in most program areas by grade level categories…

Five instructional techniques for increasing the meaningfulness of technical or scientific information are summarized: (1) organization of prose; (2) use of concrete analogy and advance organizers; (3) use of inserted questions in prose; (4) elaboration activities such as note taking; and (5) discovery learning. Research on each technique is…

This book, intended to serve as a resource guide for teachers wishing to implement computer-based learning in their own classrooms, is a collection of 29 classroom tested instructional programs designed to supplement an introductory chemistry course, regardless of text or approach. The programs cover a wide range of topics, from metric units of…

Information from the American Institute of Medical Climatologists on human responses to weather and climatic conditions, including clouds, winds, humidity, barometric pressure, heat, cold, and other variables that may exert a pervasive impact on health, behavior, disposition, and the level of efficiency with which individuals function is reviewed.…

This study investigated the effects of three types of diagnostic-prescriptive learning assistance, aptitude, and locus of control on the cognitive and affective biology achievement of high school students. The study also determined whether the effects of treatment (diagnostic-prescriptive teaching) were consistent across levels of student aptitude…

This handbook is designed to assist teachers in using the Science Item Bank to construct diagnostic tests and end-of-course achievement tests. The item bank consists of over 2,800 multiple-choice items, and teachers are encouraged to supplement this source of test items with other forms of test questions. Key answers to these questions are arrived…

Presented is a statement of goals and objectives to be used by the overseas dependent schools. This document is intended as a guide for program instruction by the teacher, as a basis for the evaluation of either commercial materials or those developed locally, as a basis for further evaluation of science education in the dependent schools, and as…
