Your Researcher's Logbook
Criterion E is not about your final essay; it's about the story of how you created it. Assessed through three short reflections (the RPPF), it's your chance to show the examiner your personal journey, the problems you solved, and the skills you developed along the way.
Think of your Extended Essay journey as being the captain of a ship on a long voyage of discovery. Your final essay is the treasure you bring back, but Criterion E is the captain's log. It records the storms you weathered (research problems), the new islands you discovered (unexpected findings), the difficult decisions you made (changing your research question), and how you grew as a captain (a researcher) throughout the journey. A log that just says 'Sailed from A to B' is boring and gets low marks; a log that details the challenges and your clever responses is what impresses the authorities (examiners).

Document Everything: Keep a research journal from day one. Note down ideas, dead ends, supervisor feedback, and 'eureka' moments. This is your raw material.
- 2
Focus on 'Why': For each reflection, move beyond describing 'what' you did. Explain 'why' you made a particular decision, 'how' it impacted your work, and 'what' you learned from it.
- 3
Show, Don't Tell: Instead of saying 'I showed resilience', describe a specific problem you faced (e.g., a key source was unavailable) and detail the steps you took to overcome it (e.g., contacting a university librarian, finding an alternative theoretical framework).
- 4
Connect to the Criteria: Use the language of the markscheme. Frame your reflections around your 'intellectual initiative', your 'creative approach' to problem-solving, and your 'authentic engagement' with the research process.

Deconstructing the Markbands: From 'Basic' to 'Excellent'
To excel, you must understand what examiners are looking for. Criterion E is assessed across four levels. Let's break them down:
0 Marks: The RPPF is not submitted or the comments are not relevant to the essay.
1-2 Marks (Basic): Reflections are superficial and descriptive. The student lists actions ('I found sources') without explaining the decision-making process or challenges. The engagement feels passive.
3-4 Marks (Good): Reflections show some intellectual initiative and insight. The student identifies challenges and explains the decisions they made in response. The reflections are credible and show personal involvement.
5-6 Marks (Excellent): Reflections are insightful and demonstrate authentic personal engagement. The student critically evaluates their own decisions, showing how they took intellectual risks, adapted their plans, and grew as a learner. The examiner sees clear evidence of intellectual initiative and creative/critical thinking.
The First Reflection: Laying the Foundation
This reflection, completed near the start of your journey, sets the scene. It should capture your initial enthusiasm and your early planning. Avoid generic statements like 'I am interested in History'. Instead, be specific.
Justify your Topic: Why this topic in this subject? What personal interest or prior learning sparked this inquiry?
The Research Question Journey: Don't just present your final RQ. Briefly describe the process of refining it. Did you start too broad? Did your supervisor help you narrow it down? Show the evolution of your thinking.
Initial Plan & Foreseen Hurdles: Briefly outline your initial research plan. Crucially, show foresight by identifying potential challenges. For example, 'I knew accessing primary sources from the 1920s would be difficult, so my initial plan involved contacting the National Archives early on.'
The Interim Reflection: Navigating the Research Process
This is the most critical reflection for demonstrating resilience and intellectual initiative. Research is never a straight line. This is your opportunity to document the twists and turns. This is where you prove you are an active, thinking researcher, not just a collector of facts.
Embrace the Problem: Did your initial hypothesis turn out to be wrong? Did a key source prove inaccessible? Excellent! This is your chance to shine. Describe the problem clearly.
Show Your Work: Detail the steps you took to solve the problem. Did you have to learn a new statistical test? Did you reformulate a section of your argument? Did you seek out a new type of source? This is intellectual initiative in action.
Document a 'Eureka' Moment: Describe a point where a new piece of information or a new way of thinking changed the direction of your essay. Explain how it changed your understanding.
Evaluate your Decisions: Don't just say 'I changed my plan'. Reflect on why the old plan wasn't working and why the new one is better. This shows higher-order thinking.
The Final Reflection (Viva Voce): Synthesising Your Journey
This final reflection is based on a short interview (viva voce) with your supervisor after you've submitted your essay. It's your chance to look back on the entire process from a distance. The focus should be less on the essay's content and more on your growth as a learner.
Skills, Not Just Facts: What skills did you develop? Time management, source evaluation, academic writing, resilience? Be specific. 'I learned to manage my time' is weak. 'Using a Gantt chart to schedule my writing and data analysis phases was crucial, especially when my interim experiment needed repeating' is strong.
The Big Picture: What is the most significant thing you learned from this process? Perhaps it was the importance of a well-defined question, or the realisation that academic knowledge is constantly debated and revised.
Connection to TOK: This is a great place to link your experience to TOK concepts. How did your EE journey affect your understanding of the methods of a particular Area of Knowledge? Did you encounter issues of certainty, evidence, or perspective?
Honest Self-Assessment: What would you do differently if you started again? This shows maturity and a capacity for self-evaluation, which examiners value highly.
Do not treat the RPPF as a 500-word essay. Think of it as three distinct, purposeful diary entries. Use 'I' throughout. Write in a formal but personal tone. The examiner wants to hear your authentic voice and understand your unique journey. Keep a separate research journal throughout the process and use it to draft your reflections. This ensures you don't forget the crucial details of your problem-solving.

Sample excerpt from a high-scoring First Reflection (History EE)
- 1
Initial exploration for my question on the effectiveness of the 'Dig for Victory' campaign led me to believe it was a straightforward government success. However, my supervisor prompted me to consider whose voices were missing from the official narrative. This pushed me to refine my research question to focus specifically on the campaign's impact on rural women, a perspective largely absent from my school textbook. My initial plan is now to contrast government propaganda (from the Imperial War Museum's digital archive) with anecdotal evidence from local newspaper archives and diaries. I anticipate a key challenge will be synthesising these disparate source types into a coherent argument, and I will need to develop a clear framework for evaluating their reliability.
Sample excerpt from a high-scoring Interim Reflection (Biology EE)
- 1
My initial methodology for measuring the effect of nitrate concentration on algal growth was flawed. The results were inconsistent, and I realised my control of ambient light was inadequate. After consulting with my supervisor and reading a university-level paper by Smith et al. (2019), I took the initiative to build a simple light-proof box and used a lux meter app on my phone to standardise light conditions for each sample. This setback initially felt like a failure, but redesigning the experiment forced me to engage more deeply with the principles of rigorous experimental design. The new, more reliable data has significantly strengthened my analysis section and allowed for a more nuanced conclusion than I had originally anticipated.
