The TOK curriculum is made up of three deeply interconnected parts.
1.The core theme:to understand the relationship between Knowledge and the knower, and to encourage students to reflect on the knowledge from the aspects of Scope, Persipectives, Methods and tools, Ethics.
2.Optional themes: This element provides an opportunity to take a more in-depth look at two themes of particular interest to teachers and students. The given themes all have a significant impact on the world today and play a key role in shaping people’s perspectives and identities.
3.Areas of knowledge: The areas of knowledge (AOK) are specific branches of knowledge, each of which can be seen to have a distinct nature and sometimes use different methods of gaining knowledge. In TOK, students explore five compulsory areas of knowledge: history; the human sciences; the natural sciences; mathematics; and the arts.”
In conclusion, TOK is to help students make corrections and see the whole of knowledge and logic. To that end, TOK is the essence of IB curriculum.
