Mr. Crosby's Class Blog is an inspiring record of a teacher maximizing the quality of the teaching craft while working within the bounds of our educational system. One way he does this is to go beyond the typical curriculum and system as much as he is able.  The class is piloting a laptop program using a MacBook for each child.  They blog, Skype, make videos and wiki pages. Another example is the high altitude balloon he will soon launch.  He has asked students and bloggers to postulate what will happen to the payload.
