In addition to the core theme, you will also study two out of five optional themes: knowledge and technology, knowledge and language, knowledge and politics, knowledge and religion, and knowledge and indigenous societies. These themes are relevant to our world today. They also shape your perspectives and identities. Your teacher will select two themes that are particularly interesting or relevant in your learning context. In your TOK classes on the optional themes, you will discuss key ideas such as the justification of and evidence for claims. Your understanding of the themes will primarily be assessed through the TOK exhibition. To find out more about the optional themes, check the links below.
