Per Kara Sevensma from the Education Department at Calvin College:

I believe I would recommend this blog for practitioners, but with a caution.  The opinions shared here are an excellent entry point for thinking about technology through the “lens.”  I think serious questions must be raised though about how to identify, assess, implement, and evaluate whether these technologies meet students’ needs.  The conversations about how to then examine the highlighted resources in light of important contextual factors at their placement are limited.  What I love about the blog though is that it opens up the first door (in my opinion) which is becoming aware of what resources are “out there.”  As you know, this can be one of many challenging hurdles teachers face when thinking about implementing technology.
