Math is not linear

Blanca Parra shared this Prezi with me, and I love it. It’s going into my collection of resources I can share with people about how we can change mathematics education. I wonder if we could get RSA animate or someone with similar skills to create a video related to this.



Richard Feynman on Algebra

Just watched this video thanks to Deven Page of Richard Feynman talking about algebra.

New #BCed chat: What is the relationship between assessment and learning?

On this coming Monday night, from 7pm to 8pm PST, Mr. Wejr and myself are planning a Twitter discussion about the relationship between assessment and learning. The topic is fairly broad, and should allow for anyone interested in assessment to participate. 

Make sure to use the #BCed hashtags in your tweets if you are participating, and watch out for daylight savings time. We’ll both make sure to announce the chat during the day.

We hope you will join us! If it is your first time joining a Twitter chat, see our BCed wiki page with links to some resources to get you started.

Corporal punishment

When I think of the conversations we have on Twitter about the use of technology in education, I wonder why we don’t have this conversation more often; it is not okay to hit children, especially when those children are not your own (I don’t like this qualifier, but I recognize that parents have more rights than we do as teachers, whether or not I agree with what they do with those rights).


We need to get the places in red below to codify this in law ’cause for some reason, they haven’t yet.

Adding machine – made with wood and marbles

Just thought I’d share. I wonder, could students construct something like this?
