As future teachers, this is a main, basic but difficult question that we have to ask ourselves. We find a video that comes close to our idea of : What's education for?
Even so, we are disagree with some points and we wanted to clarify it.
The goal of education for us should not be about creating workers or psychoanalyzing students desires and relationships, the goal of education is to foster intellectual curiosity that in turn results in a student loving to learn for the rest of their lives. Properly delivered education is akin to "laying out a string" by the teacher were throught questioning and guidance the students follow the "string" while drawing their own conclusions becoming free thinkers and problem solvers capable of discerning, through group/democratic debate, between rational and irrational explanations.
Each student should be free to pursue, and be encouraged to pursue, subjects and problems that interest them rather than objective based learning where the learning goals are chiseled in stone throught a curriculum created by politicians.
To sum up, we think a class should not be about what is covered in a course, but instead what is DISCOVERED in a course.
