Mathematics in engineering education causes many thresholds in the courses because of the demand of abstract conceptualisation. Electronics depend heavily on more or less complex mathematics. Therefore the concepts of analogue electronics are hard to learn since a great deal of students struggle with the calculations and procedures needed. A…

Both the purpose and overarching goal of this dissertation can be summarized with this quote by Buckminster Fuller: "You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete." That is, to enable substantive positive change in mathematics education, this…

Scholars often define historical reasoning as constructing defensible interpretations of past events. Drawing on critical theory, this article suggests that it also entails consciously framing one's topic of inquiry. The article examines an instructional unit that aimed to foster this expanded view of historiography. Forty students, ages 14-15,…

This study sought to evaluate the adequacy of integration of problematic situations and general problem-solving strategies (heuristics) in grades 9 and 10 mathematics textbooks. Grade 9 and grade 10 mathematics textbooks were used for analysis. Document analysis and interview were used as data gathering instruments. Document analysis was carried…
