Affordances of technology: Reflection on my experience

I think the discussion of what the term affordance meant is so enlightening. My perception of the term affordance is close to "possible use"  based on Salomon's theory rather than "intended use" (Conole & Dyke, 2004b).
I would like to give an example from my experiences with technology and how the affordances influenced learning. When I was in the graduate school in Turkey, I learned statistics by using SPSS. The taxonomy proposed by Conole and Dyke (2004a) made me realize that SPSS through which I learned statistics afforded me how to select and carry out statistical tests procedurally. I learned how to conduct t-tests, ANOVA, ANCOVA, MANOVA, bi-variate correlation, multiple regression, and so on. However, the technology I used afforded only procedural knowledge (i.e. how to do).
When I started my doctoral study at IU, I learned Fathom and ThinkerPlots and how to carry out the same statistical tests with those tools. While using those tools, I realized that I did not know what a particular test means and what is the difference between each other. In other words, SPSS did not allow me to learn statistics conceptually.

Readings of this week made me look at my experience and reflect on it in the light of "affordances of the technology". Even though I taught statistics with SPSS for several years, but I haven't realized that the affordances of the technology influenced not only my learning but also my teaching which resulted with procedural understanding.
