Interdisciplinary Topics in Extended Essays

Interdisciplinary EE

As an IB tutor and writer, I’ve had the privilege of guiding students through the challenging process of writing Extended Essays (EEs). One aspect that I find particularly fascinating is the research of interdisciplinary EE topics, where students can combine different disciplines to gain unique insights and perspectives. In this article, I’ll share some insights and interdisciplinary EE topic ideas to inspire IB students.

What Are Interdisciplinary Extended Essays?

Interdisciplinary Extended Essays in the IB DP program offer students a unique opportunity to examine complex issues and phenomena from multiple perspectives. There are three main types of interdisciplinary EEs.

World Studies Extended Essays (WSEE)

WSEEs are based on two or more IB subjects and research a local manifestation of a global issue. These essays are expected to be analytical and critical, focusing on understanding and addressing complex global challenges. Students can choose from various areas of study, including conflict, peace, and security; culture, language, and identity; environmental and economic sustainability; equality and inequality; health and development; and science, technology, and society. WSEEs require students to examine the interconnectedness of different disciplines and offer insights into potential solutions to global problems.

Literature and Performance Extended Essays

Essays in this category offer a critical analysis of adaptations or performances of written texts. Written texts may include novels, poems, stories, essays, articles, or play scripts, while performances may encompass film, theatrical performances, televised series, or computer games. Students can also research the contexts in which written works are conceived. Additionally, they can analyze the author’s purpose in commenting on a particular topic or theme, offering insights into the interplay between literature, performance, and society.

Environmental Systems and Societies Extended Essays (ESS)

ESS essays research the effect of human societies on the natural world. Unlike descriptive essays, ESS essays require critical analysis and evaluation of the relationship between nature and humans. Students are encouraged to dig into case studies or conduct experiments to gain deeper insights into environmental phenomena and their societal implications. You can also contribute to the discourse on environmental sustainability and stewardship by examining the complex interactions between human activities and ecosystems.

Why Choose Interdisciplinary EE Topics?

In my view, interdisciplinary extended essays provide a unique opportunity for IB students to investigate connections between different academic disciplines and break through the boundaries of traditional subject areas. I know from experience that these interdisciplinary studies address complex phenomena and offer a holistic view that incorporates multiple perspectives and methodologies.

According to general IB criteria, interdisciplinary EE involves integrating knowledge and insights from two or more disciplines to address a research question or investigate a phenomenon. Unlike traditional single-discipline essays, which focus on depth within a specific subject area, interdisciplinary works encourage students to research intersections, fostering creativity, critical thinking, and innovation. But why do so many students choose IB Extended Essay cross-discipline topics? Here are the most obvious reasons:

  • One characteristic feature of interdisciplinary EEs is their ability to bridge gaps between disparate fields of study, finding unique connections and patterns.
  • Moreover, interdisciplinary EEs often require students to develop unique skills such as interdisciplinary thinking, research integration, and cross-disciplinary communication.
  • Students working on such essays encounter unexpected connections between disciplines and challenge conventional assumptions.

So, interdisciplinary Extended Essays provide a platform for IB students to cross disciplinary boundaries, engage with different perspectives, and cultivate the skills essential for success in college and career.
