An analysis of science teacher's knowledge of specific biology and physics topics and the effects of this knowledge on their planning for instruction and on simulated teaching are discussed in this report. Six experienced secondary school teachers participated in the study. Each teacher's knowledge of a biology topic and a physics topic was…

Designed to help in the development of an educational program about the value of rain forests, this handbook presents a condensation of issues, facts, and concepts. The handbook is divided into three parts. Part one introduces the rain forest ecosystem and provides conceptual background material needed in the determination of problems, the…

Designed to address the major conceptual problems associated with evolution and variation and survival in populations, this module can be used with high school students or college nonscience majors including those in elementary education. It is one in a series developed by the project "Overcoming Critical Barriers to Learning in Nonmajors'…

This study probed children's reasoning about both correct and incorrect but plausible statements of hypothetical children concerning the concepts of subtraction, with the intention of examining misconceptions in greater depth. Eight third graders, 14 fourth graders, and 14 fifth graders were interviewed individually to assess their understanding…

This study tested the effectiveness of having fifth-grade students generate their own examples of selected concepts on energy. Hypotheses were that subjects would perform better on sections of a test related to definitions and recognition of exemplars of the concepts for which they found their own examples than on sections related to comparible…

This paper describes the characterization of a student's framework of heat and temperature, and the development of a microcomputer-based laboratories (MBL) intervention program for grade 9 and grade ll students. The report presents the results of classroom study, including interview questions and answers and pretest/posttest, from experimental and…

Misconceptions are systematic, intelligently conceived, and quite reasonable theories that have been constructed on the basis of experience. Research studies on misconceptions have indicated that students develop intelligently conceived and sophisticated concepts of science. Although some of these are compatible with the principles of modern…

The increasing availability of the computer in the classroom has created a need for informed and creative instructional software. Two areas of cognitive research in mathematics and science learning have implications to instruction and, consequently, to educational software design. These are research on misconceptions and on differences between…

Describes a common misconception in the study of mechanics. Cites textbooks as being in error for equating velocity components along the string because the string does not remain taut. Discusses the typical textbook approach to a problem of this nature and the misconception that pervades textbooks in the British Isles. (CW)

One of the great school funding myths of our time is the notion that money spent on improving public schools for poor and minority students is akin to throwing money into a bottomless pit. According to the politicians and policymakers who have pushed this view into the public debate on education reform, our schools have ample resources, and…

While there is general agreement that student attitudes toward science education are poor, there is little agreement in defining, measuring, or improving attitudes. The nature of how students relate to science rather than what they know about science is becoming an area of increased focus in science education research. This case study specifically…

Debunks mythologizing reform data concerning technology, inclusion, multiculturalism, and money. Finds little evidence that technology improves student achievement, that mainstreaming serves all special-needs students, or that minorities will soon dominate U.S. demographics. Americans' low-bid attitude toward education has created a plethora of…

Two teachers participating in professional development involving research were asked to read and respond, in light of their own teaching, to Lisa Delpit's study of the dilemma of progressive education versus teaching traditional skills to disadvantaged black students. The teachers' responses illustrate the importance of teachers' prior beliefs and…

Presented is the extent to which pupils of different ages tend to confuse scientific and everyday meanings of "Law" and "Conservation." The concepts of resource economy, environmental concern, and the law of conservation of energy are discussed in terms of potential teaching difficulties. (KR)

Describes a multiple choice, pencil and paper, diagnostic instrument used to measure student understanding of covalent bonding and structure concepts. Reports evidence of seven commonly held misconceptions. (MVL)
