What is the Mathematics Extended Essay?

The Mathematics Extended Essay is a 4,000-word independent research paper that forms a core component of the International Baccalaureate (IB) Diploma Programme. It provides students with an opportunity to explore a mathematical topic of their choice in depth, fostering critical thinking, research skills, and a deeper understanding of mathematical concepts. It's an internal assessment marking scheme that significantly contributes to your overall IB score.

Understanding the Grading Criteria

The IB Mathematics Extended Essay is assessed against five criteria: Focus and Method, Knowledge and Understanding, Critical Thinking, Presentation, and Engagement. Each criterion is designed to evaluate different aspects of your research and writing. Understanding these criteria is paramount to structuring your essay effectively and maximizing your score. Let's delve into each criterion in detail.

Detailed Breakdown of Mathematics Extended Essay Criteria

Criterion A: Focus and Method (0-6 marks)

What it assesses: This criterion evaluates the clarity of your research question, the appropriateness of your chosen methodology, and the justification you provide for selecting that methodology. It's about showing you have a clear direction and a valid approach.

Mark bands:

• 0 Marks: The topic is not clearly defined, the research question is absent or unclear, and the methodology is not described or justified.
• 1-2 Marks: The topic is vaguely defined, the research question is poorly formulated, and the methodology is described superficially with little justification.
• 3-4 Marks: The topic is generally defined, the research question is adequately formulated, and the methodology is described with some justification. Sources are limited or not always relevant.
• 5-6 Marks: The topic is clearly defined, the research question is precisely formulated, and the methodology is thoroughly described and justified. Sources are relevant, adequate in number, and contribute to the research focus.

Tips for success:

• Choose a focused topic: Avoid overly broad topics. Narrow your scope to allow for in-depth exploration.
• Formulate a precise research question: The question should be clear, concise, and answerable through mathematical investigation.
• Justify your methodology: Explain why your chosen methods are appropriate for addressing your research question.
• Use relevant sources: Ensure your sources are credible, scholarly, and directly related to your topic.

Common mistakes to avoid:

• Selecting a topic that is too broad or too simple.
• Failing to clearly define the research question.
• Not providing sufficient justification for the chosen methodology.
• Using irrelevant or unreliable sources.

Criterion B: Knowledge and Understanding (0-6 marks)

What it assesses: This criterion assesses your understanding of relevant mathematical concepts, terminology, and the appropriate use of source material. It's about demonstrating your grasp of the underlying mathematics.

Mark bands:

• 0 Marks: Demonstrates no understanding of relevant mathematical concepts or terminology. Source material is not used or is used inappropriately.
• 1-2 Marks: Demonstrates limited understanding of relevant mathematical concepts or terminology. Source material is used minimally or inappropriately.
• 3-4 Marks: Demonstrates adequate understanding of relevant mathematical concepts and terminology. Source material is used appropriately to support the essay's content. Explanation of mathematical reasoning may be unclear.
• 5-6 Marks: Demonstrates a clear and thorough understanding of relevant mathematical concepts and terminology. Source material is used effectively and appropriately to support the essay's content. Mathematical reasoning is clearly communicated and explained, including all steps in the process.

Tips for success:

• Master relevant mathematical concepts: Thoroughly understand the mathematical principles underlying your research.
• Use precise terminology: Employ accurate and appropriate mathematical terminology throughout your essay.
• Properly cite sources: Acknowledge all sources of information and ideas using a consistent citation style.
• Explain your reasoning: Clearly articulate the steps in your mathematical arguments and provide justifications for each step.

Common mistakes to avoid:

• Using incorrect or imprecise mathematical terminology.
• Failing to properly cite sources.
• Presenting mathematical arguments without clear explanations.
• Demonstrating a lack of understanding of fundamental mathematical concepts.

Criterion C: Critical Thinking (0-12 marks)

What it assesses: This criterion assesses your ability to analyze, evaluate, and draw conclusions based on your research, demonstrating sound mathematical reasoning. This is the most heavily weighted criterion, emphasizing the depth of your analysis.

Mark bands:

• 0 Marks: No evidence of critical thinking, analysis, or evaluation. Conclusions are absent or unsupported.
• 1-3 Marks: Limited evidence of critical thinking, analysis, or evaluation. Conclusions are superficial and weakly supported.
• 4-6 Marks: Some evidence of critical thinking, analysis, and evaluation. Conclusions are generally supported by evidence, but the analysis may lack depth.
• 7-9 Marks: Good evidence of critical thinking, analysis, and evaluation. Conclusions are well-supported by evidence, and the analysis demonstrates a good understanding of the mathematics used.
• 10-12 Marks: Excellent evidence of critical thinking, analysis, and evaluation. Conclusions are strongly supported by evidence, and the analysis demonstrates a deep and insightful understanding of the mathematics used. Data analysis includes appropriate mathematical transformations, statistical analysis, or graphical representation.

Tips for success:

• Analyze your findings: Go beyond simply presenting results. Analyze the significance of your findings and their implications.
• Evaluate different perspectives: Consider alternative approaches or interpretations of your data.
• Draw well-supported conclusions: Ensure your conclusions are logically derived from your analysis and supported by evidence.
• Demonstrate mathematical reasoning: Clearly explain the mathematical principles underlying your analysis and conclusions.
• Use data effectively: Employ appropriate mathematical transformations, statistical analysis, or graphical representations to support your analysis.

Common mistakes to avoid:

• Presenting conclusions without sufficient analysis or evidence.
• Failing to consider alternative perspectives or interpretations.
• Making unsupported claims or generalizations.
• Demonstrating a lack of mathematical reasoning in your analysis.

Criterion D: Presentation (0-4 marks)

What it assesses: This criterion assesses the structure, layout, and overall presentation of the essay, including the appropriate use of graphs, figures, and tables. Clarity and organization are key.

Mark bands:

• 0 Marks: The essay lacks structure and organization. Graphs, figures, or tables are absent or inappropriately used.
• 1 Mark: The essay has a basic structure, but the organization is weak. Graphs, figures, or tables are poorly labeled or of poor quality.
• 2 Marks: The essay has a clear structure, but the organization could be improved. Graphs, figures, or tables are appropriately labeled and of acceptable quality.
• 3-4 Marks: The essay has a clear and logical structure with effective organization. Graphs, figures, or tables are appropriately labeled, of good quality, and enhance the presentation of the essay. Includes a title page and table of contents.

Tips for success:

• Structure your essay logically: Use clear headings and subheadings to organize your content.
• Use graphs, figures, and tables effectively: Choose appropriate visuals to illustrate your findings and enhance understanding.
• Label visuals clearly: Ensure all graphs, figures, and tables are properly labeled with descriptive titles and axis labels.
