What is the Computer Science Extended Essay?

The Computer Science 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 computer science topic of their choice in depth, developing research, analytical, and writing skills. The essay is externally assessed and contributes significantly to the final IB score.

Understanding the Grading Criteria

The IB Computer Science Extended Essay is assessed against five criteria: Focus and Method, Knowledge and Understanding, Critical Thinking, Presentation, and Engagement. Each criterion carries a specific weight, contributing to the overall score out of 34. Understanding these criteria is crucial for planning, writing, and refining your essay to meet the IB's expectations.

Detailed Breakdown of Computer Science Extended Essay Criteria

Criterion A: Focus and Method (6 marks)

What it assesses: This criterion assesses the clarity of your research question, the rationale for choosing your topic, and the appropriateness of your chosen methodology. It's about demonstrating that you have a clear direction and a sound plan for your research.

Mark bands:

• 0 Marks: The essay lacks a clear focus, the research question is absent or poorly defined, and the methodology is not described or is inappropriate.
• 1-2 Marks: The research question is present but lacks focus or is too broad. The rationale for the topic is weak, and the methodology is vaguely described.
• 3-4 Marks: The research question is reasonably focused and relevant to computer science. The rationale for the topic is explained, and the methodology is described, but may lack detail.
• 5-6 Marks: The research question is sharply focused, accessible, and clearly related to computer science. The rationale for the topic is well-explained, the methodology is clearly described and justified, and authoritative sources are utilized.

Tips for success:

• Choose a specific and manageable research question: Avoid overly broad topics. For example, instead of "The impact of AI," consider "The effectiveness of convolutional neural networks in image recognition for medical diagnosis."
• Clearly justify your topic's relevance: Explain why your chosen topic is important and how it contributes to the field of computer science.
• Provide a detailed and justified methodology: Explain the steps you will take to answer your research question, including data collection methods, algorithms used, and evaluation metrics. Justify why these methods are appropriate for your research.
• Use authoritative sources: Rely on peer-reviewed academic papers, reputable journals, and established textbooks to support your methodology and arguments.

Criterion B: Knowledge and Understanding (6 marks)

What it assesses: This criterion evaluates your understanding of the subject matter, demonstrated through the use of appropriate terminology, explanations of information from sources, and evidence of personal comprehension.

Mark bands:

• 0 Marks: The essay demonstrates little to no understanding of the subject matter. Terminology is absent or misused, and information from sources is not explained.
• 1-2 Marks: The essay demonstrates limited understanding of the subject matter. Terminology is used sparingly or inappropriately, and explanations of information from sources are superficial.
• 3-4 Marks: The essay demonstrates a reasonable understanding of the subject matter. Terminology is used appropriately, and explanations of information from sources are provided, but may lack depth.
• 5-6 Marks: The essay demonstrates a strong understanding of the subject matter. Terminology is used accurately and effectively, explanations of information from sources are clear and insightful, and personal comprehension is evident.

Tips for success:

• Use precise computer science terminology: Avoid vague or ambiguous language. Define key terms and concepts clearly.
• Explain information from sources in your own words: Don't just copy and paste information. Demonstrate that you understand the concepts by explaining them in your own terms.
• Show personal comprehension: Go beyond simply summarizing information. Analyze and interpret the information, and draw your own conclusions.
• Provide examples and illustrations: Use concrete examples to illustrate your understanding of complex concepts.

Criterion C: Critical Thinking (12 marks)

What it assesses: This criterion assesses your ability to research, analyze, discuss, and evaluate information critically, leading to well-supported conclusions. It's the most heavily weighted criterion, emphasizing the importance of analytical and evaluative skills.

Mark bands:

• 0 Marks: The essay lacks critical thinking. Research is superficial, analysis is absent, discussion is limited, and evaluation is not present.
• 1-4 Marks: The essay demonstrates limited critical thinking. Research is basic, analysis is weak, discussion is superficial, and evaluation is minimal. Conclusions are unsupported.
• 5-8 Marks: The essay demonstrates reasonable critical thinking. Research is relevant, analysis is present but may lack depth, discussion is adequate, and evaluation is attempted. Conclusions are partially supported.
• 9-12 Marks: The essay demonstrates strong critical thinking. Research is thorough and relevant, analysis is insightful and well-supported, discussion is comprehensive, and evaluation is effective. Conclusions are justified and consider limitations and future research.

Tips for success:

• Conduct thorough and relevant research: Go beyond basic internet searches. Consult academic databases, journals, and conference proceedings.
• Analyze information in depth: Break down complex concepts into smaller parts and examine their relationships. Identify patterns, trends, and anomalies.
• Engage in comprehensive discussion: Explore different perspectives and viewpoints. Consider the strengths and weaknesses of different arguments.
• Evaluate information effectively: Assess the credibility and reliability of sources. Identify biases and limitations.
• Draw well-supported conclusions: Base your conclusions on evidence and analysis. Justify your claims and consider alternative explanations.
• Acknowledge limitations and suggest future research: Demonstrate awareness of the limitations of your research and suggest areas for further investigation.

Criterion D: Presentation (4 marks)

What it assesses: This criterion assesses the structure, layout, and adherence to academic standards, ensuring the essay is clear, easy to understand, and meets the formal requirements.

Mark bands:

• 0 Marks: The essay lacks structure and organization. Academic standards are not met, and referencing is absent or inaccurate.
• 1 Mark: The essay demonstrates some structure, but organization is weak. Some academic standards are met, and referencing is attempted but may be incomplete or inaccurate.
• 2-3 Marks: The essay is generally well-structured and organized. Academic standards are mostly met, and referencing is generally accurate and complete.
• 4 Marks: The essay is well-structured, organized, and adheres to academic standards. Referencing is accurate, complete, and consistent. The presentation enhances reader comprehension.
