Explores and documents the frequencies of conceptual difficulties confronted by college students (n=200) seeking to understand the basic processes of cellular respiration. Findings suggest that novices harbor a wide range of conceptual difficulties that constrain their understanding of cellular respiration and many of these conceptual problems…

Presents the Vector Knowledge Test that was designed to see if beginning physics students possess the minimal basic knowledge of vectors that will allow them to proceed with a study of Newtonian mechanics. Concludes that only one-third of the students in a calculus-based introductory course at California Polytechnic had sufficient vector…

Study of strategies and procedures of 170 students and 40 teachers when solving chemical equilibrium problems found misconceptions emerging through: misapplication of Le Chatelier's Principle, use of rote-learning recall, incorrect control of variables, limited use of chemical equilibrium law, lack of mastery of chemical equilibrium principles,…

Decentralization proponents argue that autonomous decision making at the school level will significantly affect teaching and learning, leading to improved outcomes. The problem is to distinguish real autonomous decision making from a degree of managerialism that decentralizes administration, rather than decision making. A five-part analytical…

Discusses some core features of Aristotelian physics and looks at their transformation by first Galileo and then Newton. It shows how the Aristotelian view was rooted in commonsense and indicates the reason that such understandings prove so resistant to physics instruction. Some suggestions are made for guiding effective pedagogy. (Author/PR)

Surveys of 295 undergraduate students in college algebra and precalculus about their perceptions of mathematics found that agreement with some mathematical myths can be reduced with more mathematical preparation of students. Suggests strategies to overcome these myths. (13 references) (MKR)

Offers a strategy for eliminating or at least diminishing students' preconceptions and misconceptions using two inseparable components: a pretest to identify the students' preconceptions and a technique of teaching by comparison between right and wrong responses to remove the preconceptions. (MVL)

Comments on Flavell's paper (PS 522 962) presented in the same issue. Stresses some of the positive aspects of preschoolers' conception of thinking, and raises questions about the relatively negative portrait of young child's introspective abilities. Discusses evidence of introspection among preschoolers, and underlines the special, and…

Comments on Flavell's paper in this issue. Examines the paper's findings on three different aspects of children's knowledge about thinking: their ability to differentiate thinking from other activities, their awareness that thinking is always going on in people's minds, and their capacity for introspection into their own thinking. Argues that…

Borg, Mason, and Shapiro in "The Economic Consequences of State Lotteries" (Praeger, 1991) argue that the Florida lottery creates an implicit tax that is inequitable and inefficient. These conclusions are unconvincing. Are lotteries really responsible for 35% reductions in pupil spending in lottery states? Additional work by Borg and…

Responding to critique of "The Economic Consequences of State Lotteries" (Praeger, 1991), coauthor praises reviewers' analysis and deplores their harsh criticism. Income coefficient used is justifiable, since, in Florida, number of children attending state-funded schools is positively associated with income. Would have received even…

Responding to a critique of the book "The Economic Consequences of State Lotteries" (Praeger, 1991), a coauthor thanks reviewers for an in-depth analysis and comments on their remarks about the book's efficiency section. Reviewers misread the original authors' observations concerning elasticity of demand, inefficient diversions of…

The authors of this article call for increasing racial and cultural diversity among those setting the agendas of environmental education. Seven misconceptions in environmental education that impede the participation of people of color are discussed. Concludes with a list of questions educators can use to evaluate their own programs.

Discusses and provides an example of reflectivity approximation to determine whether reflection will occur. Provides a method to show thin-film interference on a projection screen. Also applies the reflectivity concepts to electromagnetic wave systems. (MVL)

Discusses the integration of assessment into instruction using a four-step framework: planning the activity, gathering evidence, interpreting evidence, and using evidence. (MKR)
