I have read over half of How Computer Games Help Children Learn by David William Shaffer (http://www.amazon.com/gp/product/0230602525/ref=oh_details_o02_s00_i04).  I have found the book to be very interesting so far.  The main point of the book (so far) seems to involve placing students in game based learning.  Game based learning involves placing students in the role of a scientist, architect, or some other role in solving a problem or dilemma.  Students participate in simulations and learn various aspects of what it means to be a person in that role.  Students begin to learn the skills and knowledge associated with performing the role of that profession.  In his book, Shaffer cites several examples of students using games.  He carefully documents their experiences, attitudes, and changes in thinking over time.  I see tremendous potential here to help students learn in 21st century fashion.  Perhaps one of the most interesting evidences that he documents involves students helping other students in the true spirit of collaboration.  I look forward to continuing to read the book and gleam Shaffer's insights.
