Study Notes
2025 DSE Geography Fieldwork-Based Questions (FBQs)
- Topics include Changing Industrial Location, Disappearing Green Canopy, and Climatic Change.
- The fieldwork process has four key stages: planning and preparation, data collection, data processing and presentation, and conclusion.
Step 1: Planning and Preparation
- Factors to consider for trip planning include season, day, time, weather, accessibility, and safety.
- Necessary data: relevant previous fieldwork data, potential high risks, advantages/ disadvantages of the chosen seasons/ dates/ times.
Step 2: Data Collection
- Key elements of data collection include six probabilistic and eight non-probabilistic sampling methods.
- Examples of sampling methods (probabilistic): random sampling, systematic sampling, stratified sampling.
- Examples of sampling methods (non-probabilistic): convenience sampling, quota sampling, purposive sampling.
- Use of primary data (data collected directly by the students during fieldwork) and secondary data (data collected from other sources).
Step 3: Data Processing and Presentation
- Data Processing: Categorization, combination, counting, calculation, GIS
- Data Presentation: 7 graph types (line graph, bar graph,, histogram, pie graph, triangular graph, scattergram, radar chart), correlation, types of thematic maps.
Step 4: Conclusion
- Summarize findings from data processing and interpretation.
- Draw conclusions based on the analysis.
- Extreme values should be checked and/or corrected as they can influence results and conclusions.
Additional Details
- Fieldwork topics often involve investigating the relationship between two variables (e.g., light intensity and undergrowth coverage, river discharge and course).
- Correct methodology: Using correct sampling techniques and data collection methods to ensure the validity and reliability of results.
- Practical considerations: Fieldwork schedules and locations should be appropriately selected and factors like time, weather conditions, human interference, and the reliability of instruments should be taken into consideration to ensure the data is reliable and valid.
- Data interpretation: Conclusions should be evidence-based and supported by data and graphs.
Geographical Investigations
- Geographical investigations often focus on specific locations (e.g., a section of a river).
- Students must justify the site selection for a chosen area, including its appropriateness for a geographical investigation.
