Understanding the IB Extended Essay

What is the IB Extended Essay?

The Extended Essay is an independent, self-directed piece of research, culminating in a 4,000-word paper. It's a core requirement of the IB Diploma Programme and contributes to your overall diploma score. The EE aims to develop your research, critical thinking, and writing skills, preparing you for university-level academic work.

Why is the Extended Essay Important?

The EE is more than just a requirement; it's an opportunity. It allows you to:

  • Explore a passion: Choose a topic that genuinely interests you, making the research process more engaging.
  • Develop research skills: Learn how to formulate a research question, gather evidence, and analyze data.
  • Improve writing skills: Hone your ability to structure arguments, present evidence, and write clearly and concisely.
  • Prepare for university: Gain experience in independent research, a crucial skill for higher education.
  • Boost your university application: A well-written EE can impress admissions officers and demonstrate your academic capabilities.

Extended Essay Assessment Criteria

The EE is assessed based on the following criteria:

  • Criterion A: Focus and Method (6 marks): This assesses the clarity of the research question, the rationale for the chosen topic, and the appropriateness of the methodology.
  • Criterion B: Knowledge and Understanding (6 marks): This evaluates the student's understanding of the topic, the use of relevant sources, and the depth of analysis.
  • Criterion C: Critical Thinking (12 marks): This assesses the student's ability to analyze evidence, evaluate arguments, and draw reasoned conclusions.
  • Criterion D: Presentation (4 marks): This evaluates the clarity, organization, and structure of the essay.
  • Criterion E: Engagement (6 marks): This assesses the student's reflection on the research process and their engagement with the topic.

Understanding these criteria is crucial for tailoring your essay to meet the expectations of the IB examiners.

Choosing the Right Topic

Finding Your Passion

The first step in writing a successful EE is choosing a topic that genuinely interests you. This will make the research process more enjoyable and help you stay motivated throughout the project. Consider your favorite subjects, areas you're curious about, or topics you've always wanted to explore further.

Brainstorming Ideas

Once you have a general area of interest, start brainstorming specific topics. Ask yourself:

  • What are the key issues in this area?
  • What questions do I have about this topic?
  • What resources are available to me?

Narrowing Your Focus

It's important to narrow your focus to a manageable topic. A broad topic will be difficult to research and write about effectively. Consider the following:

  • Time constraints: You have a limited amount of time to complete the EE.
  • Word limit: The EE has a 4,000-word limit.
  • Resource availability: Ensure you have access to sufficient resources (books, articles, data) on your chosen topic.

Formulating a Research Question

A strong research question is essential for a successful EE. It should be:

  • Focused: Specific and well-defined.
  • Researchable: Answerable through research and analysis.
  • Arguable: Open to interpretation and debate.

Example:

  • Too broad: What is the impact of social media?
  • Better: How has social media impacted political polarization in the United States between 2010 and 2020?

Structuring Your Extended Essay

The Basic Structure

A typical EE structure includes the following sections:

  • Title Page: Includes the title of your essay, your name, candidate number, subject, and word count.
  • Abstract: A brief summary of your essay (around 300 words).
  • Table of Contents: Lists the main sections and sub-sections of your essay.
  • Introduction: Introduces your topic, provides background information, and states your research question.
  • Body Paragraphs: Presents your research, analysis, and arguments.
  • Conclusion: Summarizes your findings, answers your research question, and discusses the implications of your research.
  • Bibliography: Lists all the sources you used in your essay.
  • Appendices (Optional): Includes supplementary materials, such as raw data or interview transcripts.

Crafting a Compelling Introduction

Your introduction should grab the reader's attention and clearly state the purpose of your essay. Include the following:

  • Background information: Provide context for your topic.
  • Research question: Clearly state your research question.
  • Thesis statement: Briefly outline your main argument.
  • Scope of the essay: Define the boundaries of your research.

Developing Strong Body Paragraphs

Each body paragraph should focus on a specific aspect of your research question. Include the following:

  • Topic sentence: Introduces the main idea of the paragraph.
  • Evidence: Provides supporting evidence from your research.
  • Analysis: Explains the significance of the evidence and how it supports your argument.
  • Transition sentence: Connects the paragraph to the next one.

Writing a Powerful Conclusion

Your conclusion should summarize your findings, answer your research question, and discuss the implications of your research. Include the following:

  • Restatement of your thesis: Briefly reiterate your main argument.
  • Summary of your findings: Summarize the key points of your essay.
  • Answer to your research question: Clearly answer your research question based on your findings.
  • Implications of your research: Discuss the broader implications of your research and suggest areas for future study.

Common Challenges/Mistakes

Poor Topic Selection

Choosing a topic that is too broad, too narrow, or not researchable is a common mistake. Make sure to carefully consider your topic and research question before you begin writing.

Solution: Spend time brainstorming and refining your topic. Consult with your supervisor for guidance.

Lack of Focus

Failing to stay focused on your research question can lead to a disorganized and unfocused essay.

Solution: Regularly review your research question and ensure that all your research and writing is directly relevant to it.

Insufficient Research

Not conducting enough research can result in a superficial and unconvincing essay.

Solution: Dedicate ample time to research and use a variety of credible sources.

Weak Analysis

Simply presenting information without analyzing it is a common mistake.

Solution: Explain the significance of your evidence and how it supports your argument.

Poor Structure and Organization

A poorly structured and disorganized essay can be difficult to understand and follow.

Solution: Plan your essay carefully and use a clear and logical structure.

Plagiarism

Plagiarism is a serious academic offense that can result in failing the EE.

Solution: Properly cite all your sources and avoid copying and pasting text from other sources. Use plagiarism detection software to check your work.

Advanced Tips/Strategies

Seek Feedback Early and Often

Don't wait until the last minute to get feedback on your EE. Share your work with your supervisor, classmates, and other trusted individuals throughout the writing process.

Manage Your Time Effectively

The EE is a time-consuming project, so it's important to manage your time effectively. Create a schedule and stick to it.

Stay Organized

Keep track of your research, notes, and drafts in an organized manner. This will make it easier to find information and write your essay.

Proofread Carefully

Before submitting your EE, proofread it carefully for errors in grammar, spelling, and punctuation.

Go Beyond the Basics

To achieve a top score, go beyond the basics and demonstrate critical thinking, originality, and insight.
