Presents results of a study examining how introductory economics students use graphic analysis. Concludes that the difficulties students have in analyzing an economic problem graphically result from problems with concept formation. Suggests that videotaping can assist instructors to understand and anticipate the learning processes that students…

Educators will meet increasing numbers of children who are homeless, exposed to toxic substances, or infected with the HIV virus. The articles in this special section address the implications of these conditions for assessment, instruction, and administrative planning. Media-generated myths and misconceptions about the effects of these conditions…

Fourteen elementary and middle school teachers from an inservice physics course were found to share a common core of strongly held propositions that formed a coherent, but incorrect and contradictory, model of the sequential flow of electrical current. Theoretical and practical implications of these teachers' beliefs with respect to both…

Describes an African-American parent's efforts to ensure that her daughter be treated fairly in a second grade classroom. Because some teachers mistakenly believe that African-American children are not capable of performing well in the classroom, these teachers may inadvertently convey lower expectations and damage African-American students'…

If outcomes-based education is the darling of education reformers, it is the devil to conservative parents, taxpayer groups, and legislators who oppose it. Despite some initial successes in several states, critics charge that the states pushing OBE have no evidence that it works. Costs are another factor. So far, the ultraconservatives are…

Discussed is the idea that students come into their lessons with already preformed notions for many basic astronomical events. Examples of students' responses during an astronomy lesson are included. Suggestions for uncovering students' alternative frameworks are presented. (KR)

Durer's method for drawing an ellipse is used to explain why some people think an ellipse is egg shaped and to show how this method can be used to derive the Cartesian form of the ellipse. Historical background and suggestions for further reading are included. (KR)

Effects of animated graphics presentations on incidental learning and the degree to which various computer practice activities contain intrinsically motivating characteristics were studied with 70 fourth graders learning about Newton's laws of motion. Incidental learning occurred without sacrifice of intentional learning. Students were highly…

Presents a first day physics activity having students determine the fine for a speeding ticket if the speeds considered include the earth's rotation and revolution speed, and the movement through the galaxy. (MDH)

Responses of 322 university sophomores (education majors) on an evolution problem "How could the bat have evolved wings?" are analyzed and classified. Concludes that misunderstandings are logical. (PR)

This article describes the genesis and development of concept mapping as a tool for science education. It also offers an overview of this special issue of the "Journal of Research in Science Teaching" and comments on the current state of knowledge representation. Suggestions for further research are made. (49 references) (Author/PR)

Interviews were conducted with grade 10 students (n=34) who had received 4 years of physics instruction. Interview's focus was to understand students' responses from their point of view. The results of the study confirm and deepen findings from other studies concerning students' severe difficulties in learning the energy concept, the particle…

The purpose of this study involving 12 classrooms was twofold: (1) to understand the conceptual frameworks that sixth-grade students use to explain the nature of matter and molecules, and (2) to assess the effectiveness of 2 alternative curriculum units in promoting students' scientific understanding. Results reveal that students' entering…

Beginning physics students (n=42) were constrained to analyze mechanics problems according to a hierarchical scheme that integrated concepts, principles, and procedures. After five one-hour sessions, students increased their reliance on the use of principles in categorizing problems according to similarity of solution and in writing qualitative…

Synthesizes quantitatively the experimental and quasi-experimental research in reading education and science education designed to test the effects of various instructional interventions on misconceptions. Identifies specific strategies or approaches that were effective in producing conceptual change. Notes that effective procedures had a common…
