How Dragging Changes Students' Awareness: Developing Meanings for Eigenvector and Eigenvalue
Shiva Gol Tabaghi
Canadian Journal of Science, Mathematics and Technology Education Vol. 14, No. 3 (2014) pp. 223–237
The complementary use of the theories of instrumental genesis and shifts of attention enabled me to obtain insights into students' understandings of the concepts of eigenvector and eigenvalue. My analysis suggests that the use of different...

Using Dynamic Geometry Software to Explore Eigenvectors: The Emergence of Dynamic-Synthetic-Geometric Thinking
Shiva Gol Tabaghi; Nathalie Sinclair
Technology, Knowledge and Learning Vol. 18, No. 3 (October 2013) pp. 149–164
This article analyses students' thinking as they interacted with a dynamic geometric sketch designed to explore eigenvectors and eigenvalues. We draw on the theory of instrumental genesis and, in particular, attend to the different dragging...
