That's ALL, what good problem solver need to know and do.
We are learning how this model helps us to solve problems by using them in so activities and stuff like that.
I definetely love it. It makes people communicate, share ideas, find and improve mistakes, and of course Solve problems SUCCESSFULLY=)
Plan-First part of work and it helps us to understand WHY problem occures and HOW shall we act to solve it. I think its the most important part of this model.
Do-Just try all methods that as we think can help to solve a problem.
Study-Collect data. Study how those methods worked (if they worked=)) ) and what can we do to make it work better (or just work).
Act-Use your improved method and be satisfied =)))))))
