"Thinking" is not something we talk about.
There is one "right answer" to any question, and it is in the book to be read.
The teacher is the only one worth listening to.
Books and teachers are always "right", and we learn only from them, not from any other resource in the room, such as our friends.
The teacher "teaches" and the students "sit and listen" or learn passively.
If we ask enough questions about a difficult assignment, we can get the teacher to make it easier and less demanding.
