The educational systems in place all over the world can be seen as fall into two broad categories, at the most fundamental level.
The first type of educational systems we see in the world is that of those that mainly promote rote learning. Under this scheme of things, the teacher is seen as the bearer of knowledge, and the students are expected to tap into that knowledge unquestioningly. Under this scheme of things, students with the best memories tend to do very well: because success under this system revolves around being able to memorize facts and retrieve them at exam time. This model is often used by insecure governments that are afraid of having intellectual populations. Such systems of education are not totally useless. They are the systems used by the Asian Tiger economies, and they still produce productive citizens. Note that, thanks to the outsourcing business model, these are the people who you may end up dealing with, should you make a phone call looking for, say, Ymail.com help on any one of the Ymail FAQs.
The second type of educational systems we see in the world is that of those that mainly promote creative thinking. Under this model, the role of the teacher is simply that of stimulating the students to think for themselves.
