|Abstract:||Comparisons have been shown to be effective for improving students' understanding of mathematical concepts and procedures. The evidence for the effectiveness of comparisons has primarily come from laboratory experiments on analogy and analogy-based interventions in math classrooms rather than investigations of naturalistic math classrooms. As a result, the qualitative aspects of comparisons that may be important for the effectiveness of comparisons have been understudied. This paper describes preliminary research on qualitative dimensions of comparisons. Analysis of video-recordings of a math classroom resulted in identification of 244 naturally occurring comparisons that were coded along five dimensions. Two dimensions related to the ambiguity of comparisons and a system for representing such ambiguity are extensively discussed herein. Potential effects of ambiguity of comparisons on learning are outlined.|
