Communicating complex concepts to practitioners, policymakers, and other nontechnical readers is a challenge that all policy researchers face. Research in education uses many concepts from methodology and statistics. If researchers want to communicate their findings to an audience of other researchers, they can safely assume that their audience is…

Statistics is an integral part of the K-12 mathematics curriculum (age 5-18). Naturally, students construct misconceptions of what they learn. This article discusses The Bop It[C]Challenge, a review activity assesses student understanding and reveals their misunderstandings of statistical concepts. (Contains 3 figures and 1 table.)

This research investigates the effect of classroom explicitation of initial conceptions (CEIC) on conceptual change in the context of learning electricity. Eight hundred and seventy five thirteen year-olds were tested in laboratory conditions to see if CEIC is or is not a productive step toward conceptual change. All students experienced a…

This paper introduces a method for mining multiple-choice assessment data for similarity of the concepts represented by the multiple choice responses. The resulting similarity matrix can be used to visualize the distance between concepts in a lower-dimensional space. This gives an instructor a visualization of the relative difficulty of concepts…

Focuses on students' understanding of electric circuits. Findings suggest that children's interpretive frameworks of electric circuits are reflected in the specificity of the details, consistency, and coherence of their understanding. Contains 23 references. (DDR)

Reports on a study that uses psychometric modeling to rank the appeal of a variety of children's astronomical ideas on a single uniform scale. Findings support the view that alternative conceptions may be markers of progress toward understanding. Contains 82 references. (DDR)
