In one of my rounds to my favorite blogs and online periodicals, I found a great article at Edutopia by Diane Darrow. It lists great iPad apps for developing higher order thinking skills. Each list will highlight a few apps that connect to the various stages on Bloom's continuum of learning.
In a similar vein, I found this Bloom's Taxonomy revisited by Kathy Schrock.
I found it fascinating reading and discovered several new apps I am anxious to try!!
