This is a great lesson written by Lisa Johnson @ComputerExplore. It is interesting how she always gets her students to use a series of apps and that the apps are always just the tools and not the reason for the lesson. This is a good example of how a teacher uses the appropriate technology to get their students to delve into their own learning often using tasks that reference Bloom's Taxonomy as the basis for a deeper understanding.

This lesson would be just as effective in an Art class where instead of writing the students were asked to create a drawing, painting or mixed media work with the same prompts. It could be used in a History class or even a Social Studies class with images from a historical event or different cultures you are studying. This really is a versatile concept from Lisa.
