Upto 8th class, Project Based Learning (PBL) will be used to teach most of the concepts. After 8th class, lecture based methods along with PBL may be used.
Project based learning need not be expensive. It can be done for any economic level. It is just a way of teaching. Project problems can be decided depending on the budget.

Project Based Learning is used in India as well in some schools, like Mirambika.
