This material reinforces the concept that know is 40% and Doing is 40%, Yes I said 40% each because the student also needs to know how to corrolate one with the other, for example. One student excels at the hands on but cannot grasp the technical concept of what he is doing and another student dominates the technical concept but doesn't see how to take the data learned and use it to complete a task. Student a can see the task in thier mind and how to manipulate it and student B understands the concept but can't manipulate the task.
