With new technologies constantly coming on-line, and with states like California, Texas, and Oregon allowing digital curriculum to replace printed curriculum, the question arises: what will textbooks look like in the coming years?

Dale’s post, “A hunger for good learning,” featured a fantastic video about teaching math. In a few brief minutes, Dan Meyer showed us a photo of a math problem involving filling a tank of water and calculating how long that would take, then showed us why traditional approaches to teaching this problem stifled student learning. The picture showed a traditional math problem with a line drawing of the tank, a problem set-up written in text (octagonal tank, straight sides, 27oz per second, etc.) followed by short sub-steps that are needed to solve the problem (calculate the surface area of the base, calculate the volume). Then, finally, it asks the question “how long will it take to fill the tank?”

It's an amazing time to be a learner - Will Richardson. Your personal learning network is not just a network of people you learn from.

A "pln," as enthusiasts call them, is a network of people who are learning together. I was given this essential lore - and truth be told, much of what I know about social media in education - by Will Richardson.

In part, this blog post and interview is a form of reciprocation: you know you have succeeded as an educator when your students start teaching to others what they learned from you.
