Statement 2: In schools which embrace the child-centered approach, discipline is weak.

I think this statement is not true, they only misinterpret the design. In my own opinion this design is a great type of learning because it actively creates, construct meanings & understanding as viewed by the constructivist. Child-centered design seta an interaction between the teachers, the environment & the students.

Because learning is a product of the childs' interaction with the environment.
