Educational Technology and Mobile Learning have created a list of 22 Google Chrome Apps that are useful for education. The list is not exhaustive but I have found most of these to be useful.
Here is another article that is interesting look at Argument Writing across Content Areas by Heather Wolpert-Gawron. I am reading Minds Made For Stories by UNH English Professor by Thomas Newkirk. Professor Newkirk challenges the idea that narrative writing and informational writing are different. He maintains that narrative storytelling is, in his own words, the Mother of all Modes” of discourse. Both Wolpert-Gawon’s and Newkirk’s arguments are very compelling and should be considered as the Common Core calls for more emphasis on information reading and writing.
