If someone has already started a conversation on a teacher group of collaborators similar to the following suggestion, I missed it, and I apologize for the repetition. I’d like to join your group if it exists. If such a group does not exist, here are some observations and an idea.

Strangely, I’ve had some familiar experiences here on Classroom 2.0 as a new online social network member. These online experiences are a lot like the experiences I’ve had while attending other large… Continue

I've seen educational reforms come and go, and none of them have changed much if anything in teaching and learning. It seems now that the reform will be from the bottom up.

For my masters thesis project I am required to collect questionnaires from teachers who use Web 2.0 tools in their classrooms. I was wondering if you would be so kind as to do one of my questionnaires (short, only 6 questions)? I would be happy to email it to you at your convenience. I thank you in advance for you time and assistance. :)

I came to your page and added you as a friend because I read your post abour Diigo and watched your screencast. I had never heard of Diigo before, and adult education teachers in CA will be really interested in it, I believe, so thanks!

At 10:06pm on April 12, 2007, Kelly Christopherson said…: Dave, I look forward to some great conversations. Btw, we are just starting AP in our school - English and Studio Art for next year. I'm excited about this as it will give some students more of a challenge and an opportunity to use their talents.

I posted more on the AP US History project on my page and I confess, I haven't figured this network out completely yet so I'm not sure where I would be cross posting. Next year they might even be ready to research with kids in another school.
