In our mathematics methods courses for elementary preservice teachers, we work to uncover and confront students' understandings as well as misconceptions about important mathematical topics. Karp and colleagues' ("Teaching Children Mathematics", 21(1), 18-25) "13 Rules That Expire" article has been a useful resource for us to…

The aim of this study was to examine the concept development of decimal numbers in 244 Chinese elementary students in grades 4-6. Three grades of students differed in their intuitive sense of decimals and conceptual understanding of decimals, with more strategic approaches used by older students. Misconceptions regarding the density nature of…

This study examined Advanced Placement Calculus students' mathematical understanding of rate of change, after studying four years of college preparatory (integrated or single-subject) mathematics. Students completed the Precalculus Concept Assessment (PCA) and two open-ended tasks with questions about rates of change. After adjusting for prior…

This article describes the methods and impact of a student-teacher-scientist research partnership on student attitudes. The partnership objective was to teach students about the diverse roles of sharks in the marine environment while personally connecting students with scientific study. Students (N = 229) participated in lessons about shark…

Many years ago, Arons pointed out the incomprehension science students exhibit of the basic mathematical operations multiplication and division and the need to address the problem in physics classes to assure student understanding of the physical world. McDermott et al.'s Physics by Inquiry program does address this need directly and in detail (by…

Discussed is an approach to learning in which students are given the opportunity to discuss and rationalize the conflict between the students' existing misconceptions and the phenomenon to be studied. Curriculum materials for a unit on acids and bases were developed using this strategy. (KR)

This research was conducted to examine the conditions under which learner-generated illustrations serve as an instructional strategy promoting conceptual change. Specifically, the nature of students' misconceptions and the effects of student-generated descriptive drawings on conceptual understanding of scientific principles associated with the law…

The effects of bridging analogies teaching strategy and gender on Turkish high school students' misconceptions in mechanics were investigated. After a pilot study with 67 students in a nearby high school, the researchers' administered the revised Mechanics Misconception Test to 119 high school students as a pretest. Students in the experimental…

Discussed is an alternative teaching strategy to uncover and assess a common misconception in the life sciences and to articulate its use in teaching a unit on angiosperm reproduction. The learning cycle is described, and a concept map on reproduction on angiosperms is included. (KR)

The reform documents of the 1990s stressed that science is not practiced by a rigid scientific method, but science texts continue to describe the process as if it were rigid and linear. The purpose of this investigation was twofold: (a) to explore middle school in-service teachers' perceptions of scientific methodology and (b) to explore ways in…

Reports misconceptions identified in students with respect to the topic of parallel lines and the teaching strategies found to be useful in challenging those misconceptions. (11 references) (MDH)

Reports that young children in the pedestrian accident prone age range of four-eight years hold a variety of naive conceptions regarding speed. Proposes a primary science unit using a conceptual change approach. (MVL)
