An interdisciplinary EE blends two IB subjects to explore a single research question. Instead of using just one subject's concepts, theories, perspectives, methods, and ideas, you combine them to create a deeper, more original analysis that wouldn't be possible by studying just one subject alone.
Key Points to Remember:
On Integration: You don't need to have it all figured out from the start. Integration develops as you write. Begin by applying methods from both subjects to your question, and your combined argument will emerge through the process.
On Balance: The two subjects don't need to be used equally. The balance should fit your topic and research question, but you must clearly show how using both subjects was essential to your findings.
On Rigour: Your essay must show a solid understanding of both subjects.
Strong Recommendation: You should be formally studying at least one of the two subjects you choose.
Supervisor's Role: Check in regularly with your supervisor to ensure your research is thorough and meets the standards for both disciplines.
NOTE: Do not consider ESS or Literature and Performance for the Interdisciplinary pathway. They can be chosen in the subject-focused pathway. If you are interested in combining Theatre and Literature, choose Literature and Performance in the subject-focused pathway. If you are interested in a topic that combines Geography and Biology, depending on the nature of your topic, consider choosing ESS in the subject-focused pathway.
Writing an Interdisciplinary EE
There are two components, and you may choose these in the order that makes the most sense to you.
Either way, your EE will combine TWO subjects and ONE framework area into a narrow topic and eventually a focused research question: 2 Subjects + 1 Framework area -->> One topic -->> One RQ

The five frameworks in the figure above are designed to help you develop an interdisciplinary EE topic from your personal interests. They provide a useful starting point for your research.
Please note:
Frameworks can overlap; your topic may fit one best but share aspects of another.
Your topic does not need to address every word in a framework's title.
The same topic could fit a different framework, depending on your research question's emphasis.
While you must officially register your essay under one framework for IB, this choice is for administrative purposes and is not directly graded. Its primary purpose is to guide your initial inquiry.
The possibilities for your interdisciplinary essay are endless. To get you started, here are a few ideas for each framework.
Power, equality, justice
Culture, identity, expression
Movement, time, space
Evidence, measurement, innovation
Sustainability, development, change

Finalizing the Topic
Once you are engaged by an idea, examine your thinking to choose a specific topic. You will probably do some preliminary reading around your topic area to explore what's possible.
