EJMT Abstract

In this paper, we propose that dynamic course core has an essential role in developing teacher’s subject matter knowledge of mathematics. We are presenting three technology based mathematical conceptual activities designed to improve teachers’ mathematical knowledge for teaching the mean value theorem, the Cauchy mean value theorem, the inverse image of parametric curves, and the global minimum of total squared distances among non-intersecting curves or surfaces. These activities can help to develop teachers’ representational fluency of aforementioned topics. They can also deepen teachers’ conceptual understanding of these mathematical constructs through the use of technological tools in teachers’ education and mathematics instruction.
