Last winter I published a series of charts in which I compared popular ed tech tools for things like blogging, informal assessment, and video production. As is to be expected in the tech world, some of the tools in those charts have changed. Therefore, I’m now going through each chart and updating it. The first one I’ve updated is this chart comparing five popular platforms for creating classroom blogs. The chart is embedded below as a PDF. You can also get the Google Docs copy here.
