Preservice Teachers' Understanding of the Relation between a Fraction or Integer and its Decimal Expansion: The Case of 0.9 and 1
Dubinsky, Ed; Arnon, Ilana; Weller, Kirk
Canadian Journal of Science, Mathematics and Technology Education, v13 n3 p232-258 2013
In this article, we obtain a genetic decomposition of students' progress in developing an understanding of the decimal 0.9 and its relation to 1. The genetic decomposition appears to be valid for a high percentage of the study participants and suggests the possibility of a new stage in APOS Theory that would be the first substantial change in the theory since its inception (Dubinsky & Lewin, 1986). Our analysis includes a relatively objective and highly efficient methodology that might be useful in other research and in assessment of student learning.
