2. Advices and Tips for TOK

2.1 Advices for the TOK Essay

You will be asked to choose one title from the 6 prescribed essay titles. The essay will be focused on answering the title and you will be expected to explore this through various areas of knowledge along with real life situations. The more you link your opinions to the areas of knowledge, the better your essay gets. Moreover, don’t forget to use your real life examples to support your arguments!

2.1 Advices for the TOK Exhibition

For the TOK Exhibition you would be expected to choose one prompt from the 35 IA prompts written in the TOK guide. Then, you will have to create your exhibition around that specific prompt. The exhibition has to be linked to either at least one core theme or an optional theme.

One of the things that you should be aware of is that you can’t use photos from the internet nor something that is very common. For example, if you want to use a photo of scissors, you will have to take a picture of your own pair of scissors instead of using something that is on the internet.

You will be expected to create a file that includes everything that you have used for your exhibition including your objects/ photos and your commentaries. Don’t forget to ask your teachers for advices whenever you need help!

3. Additional Information for TOK

3.1 TOK Core Theme

You will be exploring the Knowledge and the Knower for TOK. Knowledge refers to knowledge itself and Knower refers to the people who are obtaining the knowledge- us. By focusing on these points, we will be able to explore questions such as “How does our personal values affect knowledge?” or “What kind of knowledge is our retained knowledge?”.

3.2 Areas of Knowledge (AOK)

There are only 5 AOKs for this curriculum : Mathematics, Natural Sciences, Human Sciences, History, and Arts. Other than these AOKs, you will also have to choose two themes from the following 5: Technology, Politics, Religion, Indigenous Societies, or Language. Keep in mind that ethics is included within the 5 AOKs.

3.3 Tools for Analysing the AOKs

In this curriculum, you will be using 4 tools to analyse the AOKs: Scope, Method and Tools, Perspective, and Ethics. Together, these make up the Knowledge Framework, and you will be required to use them in your Exhibition and your Essay.

3.4 Learning About the Knowledge Question

You will learn about how the Knowledge question differs from normal questions that we have in our lives. The curriculum introduces the core aspects of the knowledge question, including the fact that it doesn’t have a fixed answer to it and that it is a question that asks about our knowledge in general. By having this taught in the curriculum, it means that the knowledge question is rather fixed for your Exhibition or Essay. Hence, this also means that you can use the knowledge question you have learned in class directly.
