da Silva, Ricardo Scucuglia Rodrigues; Barbosa, Lara Martins; Borba, Marcelo C.; Ferreira, André Luis Andrejew – ZDM: Mathematics Education, 2021
In this research we investigate how mathematics teachers, as graduate students, estimate the value of [pi] by exploring the problem of "squaring the circle" using digital technology. Initially, we mention some aspects of teaching and learning of calculus in the literature, emphasizing studies that use the notion of humans-with-media to…

Gordon, Sheldon P. – International Journal of Mathematical Education in Science and Technology, 2017
This article uses dynamic software in Excel to demonstrate several ways in which graphical and numerical approaches can be introduced both to enhance student understanding of l'Hopital's Rule and to explain why the Rule actually works to give the "right" answers. One of the approaches used is to visualize what is happening by examining…
