A model for developing instructional analogies was used to produce experimental treatments that included text from a high school biology textbook to which was added extended verbal analogies written by the researcher linking each of two biology concepts to analogous familiar concepts. The control treatment was text from the biology textbook…

A large proportion of college students majoring in science are unable to translate even simple sentences into algebraic equations. Given the following sentence, "There are six times as many students (S) as professors (P) at this university," 37% of 150 freshmen engineering students in a study conducted in 1981 by Clement, Lockhead, and Monk wrote…

Southern College of Technology (SCT) is the only institution in the University of Georgia system to offer a developmental physics course to give students with no previous physics coursework the conceptual background and vocabulary needed to complete SCT's physics requirements. The eight sections of the developmental course focus on: (1) literal…

Many words which have been treated in the denotative sense are actually connotative in nature. That is to say that citing a definition or stating a fact should not be a learning goal. Rather, a "conceptualization" should be what teachers are striving for. A series of activities dealing with density have been provided for demonstrations or…

Twin aims--to advance theory and to improve practice in science, mathematics, and computing education--guided the Educational Technology Center's (ETC) research from its inception in 1983. These aims led ETC to establish collaborative research groups in which people whose primary interest was classroom teaching and learning, and researchers…

Science Unlimited (Pennsylvania Department of Education's elementary science effort) has developed a series of television programs for use in the primary and intermediate grades. These television programs form an integral part of science lessons which emphasize direct involvement of children with materials and ideas, provide for individual and…

The diversity of the educational system of the United States that engenders a wealth of innovative ideas and varied practices also makes it an extremely complex system to confront and understand as a whole. This survey was undertaken to develop current baseline data on all secondary school teachers of physics in the United States, including those…

This paper attempts to discover and describe the salient common factors constituting four high school science teachers' role conceptions. In a year-long ethnographic study, two researchers worked as participant observers in various science classroom settings at an urban high school. Teachers in charge of these classrooms were interviewed on issues…

A series of computer-based activities were integrated into the laboratory portion of a two-semester university biology course for elementary teaching majors. The purpose of the project was to address the biology instruction provided to the students while at the same time providing examples of appropriate uses of computers in instruction,…

This study summarizes data collection activities associated with the first two years of a large scale project involving teachers of science and mathematics with computers. The innovation being implemented in the project is that of using computer based strategies directly in the teaching of science and mathematics in the classroom and laboratory.…

An integrated competency-based course of study in the sciences is provided in the handbook for North Carolina teachers of grades K-12. Recommended goals, objectives, and suggested measures for each subject and skill area related to the sciences are outlined. This guide contains: (1) an introduction (defining North Carolina's basic educational…

Problem solving has long been a concern of science educators, with many asserting that problem solving should be both the overriding method and valued outcome of science instruction in American schools. This information bulletin synthesizes studies that deal with the relationships between the teaching of problem solving and secondary school…

The purpose of this study was mainly to: (1) assess the competencies of pre-service biology teachers in identifying and correcting student misconceptions about photosynthesis; (2) search for relationships which might exist between each competency and a set of four independent variables, namely, background knowledge about photosynthesis,…

This collection of essays focuses on the "strategic teaching" model of cognitive instruction, a model which makes clear the complex thinking process that teaching is, highlights the importance of the teaching/learning connection, and aims at enabling all types of students to become successful learners. The papers consider the varied levels at…

The six major conference papers collected in this document focus on developing ways of facilitating equity and academic achievement in a desegregated setting. The psychological impact of fostering these expectations among multicultural populations, methods for involving minority students in a science and math high-tech curriculum, and methods for…
