What is the IB Extended Essay (EE) in the IB Diploma Programme?

The Extended Essay is a crucial component of the IB program that might be slightly intimidating initially. It’s a substantial academic essay that challenges you to develop your argument through independent research. What exactly does an extended essay entail? Let me break it down for you.

At its core, the Extended Essay is:

• A 4,000-word research paper
• An opportunity for students to investigate a topic of their choice
• A chance to explore academic writing at a university level
• A requirement for the IB Diploma

This assignment is mainly to prepare you for university-level research and writing. What you’ll need to include in your extended essay goes beyond just writing a long paper – it’s about developing crucial academic skills:

Selecting Your Research Topic

The key to a successful extended essay is choosing a topic that genuinely excites you while offering enough depth for substantial research. When I work with IB students, I always emphasize the importance of selecting a topic that is neither too broad nor too narrow. Start by considering your interests across your IB courses – mathematics, science, history, or literature. Your passion for the subject will fuel your motivation throughout the research process.

Think about what makes your brain tick. What aspects of your curriculum make you feel like a nerd in the best possible way? Remember, you’ll be spending considerable time on this topic, so it should interest you. Consider current news events, academic publishing trends, or historical developments in your field.

Developing Your Research Question

A well-formulated research question is your compass throughout the writing process, guiding every decision from source selection to argument structure. This is where critical thinking comes into play. Your question should be specific enough to be answered within the word limit but complex enough to require thorough research.

When developing your question, consider these elements:

• Does it require analysis rather than just description?
• Can it be researched using available resources?
• Does it align with the assessment criteria?
• Will it allow you to develop a strong argument?

Since your extended essay will require you to defend a position, you might find our guide on how to write an argumentative essay particularly useful for developing your arguments.

Creating an Effective Research Plan

Creating an outline before diving into your sources will save you countless hours and prevent you from getting lost in a sea of information. This is where your relationship with your supervisor becomes crucial. Your IB teacher can provide valuable guidance as you plan your approach.

Start by breaking down your research into manageable chunks:

• Initial brainstorming and close reading of key sources
• Gathering evidence and data
• Planning your methodology
• Setting milestones for your first draft

Conducting In-depth Research

Successful research requires more than collecting sources – it demands careful evaluation, systematic note-taking, and strategic information organization. As you conduct thorough research, maintain a detailed bibliography and keep track of your sources. This is where your understanding of academic writing conventions becomes essential.

Consider various research.

• Interview sources (if applicable)
• Experiment design (for science topics)
• Art analysis (for humanities)
• Literary theory application

Remember to watch for potential bias in your sources and maintain a balanced perspective.

Structuring Your Argument

When writing an extended essay, your argument structure can make or break your research paper. Let me share some practical tips to help you create a compelling argument that will impress your examiners.

First, think of your argument like building a house. Your strong research question is the foundation; each supporting point is a carefully placed brick.

Before diving into your extended essay structure, you may find it helpful to understand how to structure an informative essay, as many of the same principles apply.

As you organize your ideas, consider these structural elements:

1. Main Arguments
   • Start with your strongest point
   • Support each argument with specific evidence
   • Connect each point back to your research question
   • Maintain a clear progression of ideas
2. Supporting Evidence
   • Use varied sources to support your claims
   • Balance primary and secondary sources
   • Integrate quotations smoothly
   • Explain the significance of each piece of evidence

Remember that you must demonstrate critical thinking within your subject and topic as an IB EE requirement. Show how your argument contributes to the broader discussion in your chosen field, which should be one of the six subject groups in the IB curriculum.

Pro Tip: Create a mind map of your arguments before writing. This helps ensure your ideas flow logically and support your main thesis.

Writing the First Draft

Remember that perfection isn’t the goal when it’s time to write your extended essay draft. As an experienced guide in the International Baccalaureate program, I’ve seen many students get stuck trying to write the perfect first sentence. Instead, focus on getting your ideas down in a well-structured format.

Let’s break this down into a step-by-step guide that will help you navigate the writing process:

1. Start with a clear introduction that presents your research question as a topic
2. Structure your essay logically with clear transitions
3. Support your arguments with evidence throughout
4. Maintain clarity and coherence in your writing

Remember that while an extended essay is more complex, the basic principles of how to write an essay still apply to your work.

The extended essay guide emphasizes that your first draft is crucial in completing your extended essay in IB. As you begin to write, keep these key considerations in mind:

1. Introduction (500-600 words)
   • Hook your reader with an engaging opening
   • Provide necessary background context
   • Present your research question clearly
   • Outline your methodology
   • State your thesis statement
2. Body Paragraphs (2500-2800 words)
   • Start each paragraph with a clear topic sentence
   • Present one main idea per paragraph
   • Use transitions to connect ideas
   • Include relevant evidence and analysis
   • Link back to your research question
3. Conclusion (500-600 words)
   • Summarize main points
   • Answer your research question
   • Discuss broader implications
   • Reflect on the significance of your findings

As you work through your draft, remember that this is an opportunity for students to demonstrate their ability to conduct independent research on a chosen topic. The IB extended essay guide suggests writing freely at first, then refining your work through multiple revisions.

Remember, you’ll write under the supervision of an IB teacher at your school, who can provide valuable feedback and suggestions as you progress.
