Exploring algebraic complexity

Here is an idea I am exploring.

I'd like some feedback on this idea. If anyone can point me at research already done in this area, that would be appreciated. My objective is to use this to justify the use of technology in mathematics as a way of reducing algorithmic complexity so that deeper concepts can be more readily understood.

Bad calculations

Question: If you didn't know the procedure for addition or multiplication, and lacked numeracy skills, could you catch the errors in the calculations shown here?

Open educational resources

Educators, I have some bad news to give you. You aren't going to get rich. It doesn't matter how many of your lessons you carefully hoard, or how many great ideas you keep to yourself, none of that is going to make you rich. You will probably never publish your "book" and you aren't going to get famous.

What should be on a high school exit exam in mathematics?

Personally, I think an exit exam for school (an exam a student needs to graduate from secondary school) is not necessarily the best way to determine if a student has been prepared by their school. That aside, some of sort of assessment of what a student has learned from their school, whatever form that would take, should satisfy an important criterion; that the student is somewhat prepared for the challenges that life will throw at them.

It's Spring!

My mom, my son and I went outside today and looked for signs of Spring together.

Our words are not enough: It's time for action

I'm fortunate to work in a school which gets it. We do a lot of the stuff that people on #edchat are describing as innovative, particularly in the area of student leadership and assessment policy. I feel respected every day, and my opinions and thoughts have a real impact on the direction our school goes. I know this is not true for many teachers though, and I hear it through the discussions we have on Twitter. It seems most teachers work in places where they have very little influence on school policy.

ISTE 2011 Board Elections

I'm running for the International Society for Technology in Education General Board elections. Their objective is to promote and support the use of technology in education which is one I support largely because I personally support the appropriate use of technology in schools.
