Mathematics is not medium neutral. What we call the mathematics that we can do with pencil and paper is different than what we can do with a computer and call mathematics, which is different again than the mathematics we can do with origami. The medium defines the mathematical space, in the same way that Marshall McLuhan talks about the medium being the message.

One of the teachers I work with used Angry Birds as a context for learning about quadratic functions. Whenever they wanted to introduce a new topic, they referred back to the context of Angry Birds so as to give students a representation of quadratics with which the students may be familiar.
Let's see what that could look like. Here's one angry bird shot.
Here's the data from the shot above inputted into Geogebra.

I have for some time now been subscribed to too many sources of information. As part of my transition to a new job, I have been culling various items in my feed. This is based largely on the fact that my role as an educational technologist is greatly diminished and I have less need to know about such a wide variety of tools. My focus will be much more on mathematics education, and while I think there is a role for technology to play, I think the number of tools which have potential use is much smaller.

I am reading Disrupting class, by Clay Christensen, Michael Horn, and Curtis Johnson. In the introduction of Disrupting Class, Clay Christensen, et al., give six possible reasons for why the United States education system does not appear to be doing well when compared with other OECD countries:

"If some one say: "You divide ten into two parts: multiply the one by itself; it will be equal to the other taken eighty-one times." Computation: You say, ten less thing, multiplied by itself, is a hundred plus a square less twenty things, and this is equal to eighty-one things. Separate the twenty things from a hundred and a square, and add them to eighty-one. It will then be a hundred plus a square, which is equal to a hundred and one roots. Halve the roots; the moiety is fifty and a half.
