Conclusion & Evaluation (AQA GCSE Geography): Revision Notes
Conclusion & Evaluation
The final stages of any fieldwork investigation require you to draw meaningful conclusions and critically evaluate your study. This involves reflecting on your original hypothesis, assessing the quality of your data, and identifying areas for improvement.
Drawing effective conclusions
A strong fieldwork conclusion should systematically address several key elements that tie your findings back to your original research question.
Building a Strong Conclusion
A systematic approach to conclusions helps demonstrate your analytical skills and ensures you address all the key components that examiners are looking for.
Start with your hypothesis and aim Always begin by revisiting what you set out to investigate. Reference your original hypothesis clearly and explain how your findings relate to it. This shows the examiner that you understand the purpose of your enquiry.
Present your evidence systematically Your conclusion should carefully examine the data you collected:
- Supporting evidence: Highlight findings that back up your hypothesis, using specific data and examples
- Contradicting evidence: Be honest about results that don't support your expectations - this shows critical thinking
- Unusual results: Acknowledge any anomalies in your data and suggest possible explanations
Make theoretical connections Link your findings to geographical theories and concepts you've studied. This demonstrates your ability to apply theoretical knowledge to real-world situations and shows deeper understanding.
Make a clear judgement End your conclusion by stating whether your hypothesis was supported, partially supported, or not supported by the evidence. Justify this decision with reference to your data.
Evaluating your fieldwork
What is Evaluation?
Evaluation means critically assessing the strengths and weaknesses of your investigation, particularly focusing on data collection methods and their reliability. This is not about admitting failure - it's about demonstrating sophisticated analytical thinking.
Evaluation is crucial in fieldwork as it demonstrates your ability to think critically about the research process. In exams, evaluation questions are often worth significant marks.
Focus on data collection methods Consider how well your chosen methods worked in practice:
- Were they appropriate for testing your hypothesis?
- Did they produce reliable, accurate data?
- Could different methods have given better results?
Assess the reliability of your conclusions Think about how confident you can be in your findings. Consider factors like sample size, data quality, and whether your results would be similar if the study was repeated.
Identifying issues and limitations
Every fieldwork study has limitations - recognising these shows maturity and critical thinking. Common issues include:
Sample-related problems
- Sample size: Was your sample large enough to be representative?
- Accessibility: Could you access all the sites you wanted to study?
- Duration: Did you have enough time to collect sufficient data?
Equipment and methodological issues
- Equipment problems: Did any instruments malfunction or prove inadequate?
- Human error: Were there mistakes in data recording or equipment reading?
- Question design: Were questionnaire questions appropriate and unbiased?
External factors
- Weather conditions: Did weather affect your data collection or results?
- Time of collection: Did the timing (day, season, time of day) influence findings?
- Unexpected circumstances: Were there disruptions like roadworks or events that affected results?
Suggesting improvements
Demonstrating how you would enhance your study shows excellent evaluation skills. Consider improvements such as:
Worked Example: Improving a River Study
Original limitation: Small sample size of only 5 measurement points along the river
Suggested improvement: Increase to 15 measurement points at regular 50m intervals to get more representative data and identify patterns more clearly
Justification: This would provide better coverage of the river's characteristics and increase reliability of conclusions about downstream changes.
Expanding the study
- Increase sample size for more representative results
- Take additional measurements to get more detailed data
- Use a wider range of secondary sources for context
- Extend the geographical area or time period studied
Improving methodology
- Use more accurate equipment (e.g., flow metre instead of float for river velocity)
- Design better questionnaires with clearer, unbiased questions
- Choose different sampling methods
- Collect data at multiple times to account for temporal variation
Assessing reliability
When evaluating your conclusions, consider several key factors:
Appropriateness of approach
- Did your aims and hypothesis match what you actually investigated?
- Was your chosen location suitable for testing your hypothesis?
- Could your hypothesis be easily tested with available methods?
Quality of execution
- How accurately was data collected?
- Would repeating the study produce similar results?
- Were there enough data points to draw reliable conclusions?
Scope for extension
- How could the study be expanded or developed further?
- What additional research questions arose from your findings?
- Could the methodology be applied to other locations or contexts?
Key Points to Remember:
- Always link your conclusion back to your original hypothesis and aim - this shows clear focus
- Be honest about limitations - this demonstrates critical thinking, not failure
- Suggest realistic improvements that show understanding of geographical methods
- Consider both the reliability of your data collection and the validity of your conclusions
- Use specific examples from your study to support your evaluation points
