Sometime I use problem based learning built on a previous class knowledge that the students demonstrated they learned.Using a class in demo breaking down a chicken(cutting up the chicken into a certian amount of sections). The students are shown how to do the task and then asked to preform it.In the next class I will ask the students to break down a rock cornish hen using the same techinque that the learned in the previous class.This way the student can adopt previous aquired problem solving knowledge to the present task. I belive an organization uses the saying "adopt, improvise and overcome" so do I and the results are good.
