It is spring break, so what am I doing? I am attending AP workshops and volunteering at my local university. All in all, a great spring break.

So, Let me start with the question first. Why do we make it so hard to learn functions? I mean really. We treat each topic; linears, quadratics, cubics, transendentals, etc, as if they are a new and unique idea. And they definitely are not. I have discussed this before when I was thinking about the Exeter materials, and I have to keep coming back to it for good reason.

What brought it to me today is the fact I am presenting at UNR for the professor of Math Methods to pre-service teachers. I was asked to present on calculator technology, and I will also branch out into GeoGebra, Desmos, and the MathTwitterBlogosphere.

As I was running through what I was going to say and planning my lesson I made a short video on what I wanted to show with GeoGebra. This only scratches (heck I probably doesn’t even leave a mark) on the surface of what GeoGebra can do but it is worth discussing to present it to teachers who will be immersed in Geometer’s Sketchpad in college.

And then I turn it into an HTML5 page so anyone can use it.

  And now I have a video as well as a usable piece of content for learners to look and and use on their own at home. I am trying to model good teaching practice that I use at school.

And yet, the question of why do we make linear functions separate from other so it is harder to learn than it should be still comes to my mind. Why? I don’t have a clear answer, and I am not sure anyone else does either. That is sad.
