Cool Cat Teacher - Vicki Davis's blog is everything I appreciate: current, humorous, sincere, authentic, inspiring. Her blog is filled with great resources and great tools. A first stop for teachers wanting to learn more about what technology to use, how to use it and why to use it!
Kathy Schrock's Guide to Everything - Kathy Schrock is legendary in the Ed Tech realm. She finds great tools, communicates them well, and keeps current on what is shifting and changing in education. This is a great spot to find just about anything you are looking for in terms of best practices and educational technology.
The Global Classroom Project Blog - I am partial to this blog because I have had the chance to guest blog on it (full disclosure). But what I love about it is just that, it is filled with different teachers from around the world sharing what they have tried in their classrooms, what is working, and what challenges they still face. While not strictly and educational technology blog, most of these projects that are described, use technology in some innovative way - getting students to connect, learn and work together across time zones, borders and oceans.
Free Technology for Teachers - Richard Byrne's blog is chock-full of reviews of all kinds of apps, software, web 2.0 tools and more. This is a great stop-off if you want to learn 5 new storytelling apps or the best video-editing software.
Dangerously Irrelevant - This is one of the first blogs I began subscribing to and Scott McLeod was one of the first people I began following on Twitter. His posts make me think. They challenge the traditional way of teaching and learning many of us experienced and asks powerful questions that make me reconsider what classrooms should look like. I don't always agree and sometimes it shakes my thinking too deeply, but I know I need these ideas to shape what I do and what I believe.
The Innovative Educator - It took me longer to find Lisa Nielsen but her posts serve a similar place in my professional learning and growth as do Scott McLeod's. She really pushes the envelope in terms of questioning what schooling is about and how it relates or doesn't relate to learning and education. I encourage you to check her out.
