Introduction to Geographical Enquiry

Geographical enquiry is like being a detective for the Earth! It's a structured way to investigate geographical questions and solve real-world problems. Whether you're studying coastal erosion, urban development, or river processes, the route to geographical enquiry gives you a clear path to follow.

Key Definitions:

  • Geographical Enquiry: A structured approach to investigating geographical questions through data collection, analysis and evaluation.
  • Fieldwork: The collection of primary data outside the classroom through direct observation and measurement.
  • Primary Data: Information collected firsthand by the researcher.
  • Secondary Data: Information collected by someone else and reused for your investigation.

The Route to Geographical Enquiry

Geographical enquiry follows a six-stage process that helps you organise your investigation from start to finish:

💡 Stage 1: Ask Questions

Every good investigation starts with a question! This is where you identify what you want to find out. Good geographical questions are clear, specific and can be investigated through fieldwork.

Examples:

  • "How does beach profile change along the coastline?"
  • "Is there a pattern to the quality of shops from the CBD outwards?"
  • "How does river velocity change downstream?"

🔎 Stage 2: Plan and Prepare

Once you have your question, you need to plan how to answer it. This includes:

  • Deciding what data to collect
  • Choosing appropriate methods
  • Selecting sampling techniques
  • Preparing equipment and risk assessments
  • Considering ethical issues

📊 Stage 3: Collect Data

This is the fieldwork stage where you gather the information needed to answer your question. You might use:

  • Measurements (e.g., river depth, building height)
  • Counts (e.g., pedestrian numbers, vehicle types)
  • Questionnaires and interviews
  • Field sketches and photographs
  • Environmental quality surveys

📈 Stage 4: Present and Process Data

Now you need to organise your data in a way that makes patterns clear. This might include:

  • Creating graphs and charts
  • Drawing maps and diagrams
  • Using statistical techniques
  • Making comparisons between sites
  • Using GIS (Geographical Information Systems)

🧠 Stage 5: Analyse and Conclude

This is where you make sense of your data and answer your original question. You should:

  • Identify patterns and relationships
  • Explain your findings using geographical theories
  • Consider anomalies (unexpected results)
  • Draw clear conclusions based on evidence

📝 Stage 6: Evaluate and Reflect

Finally, you need to think about how well your investigation went:

  • Were your methods appropriate?
  • How reliable was your data?
  • What limitations affected your results?
  • How could you improve your investigation?
  • What further questions have emerged?

Sampling Techniques

When collecting data, you often can't measure everything. Sampling helps you collect manageable amounts of data that still represent the whole area or population.

🗺 Random Sampling

Locations or people are selected completely randomly, giving everyone/everywhere an equal chance of being chosen.

Example: Using random number generators to select points on a beach to measure pebble size.

📏 Systematic Sampling

Data is collected at regular intervals following a system.

Example: Measuring river depth every 5 metres downstream or surveying every 10th person who walks past.

🎯 Stratified Sampling

The population is divided into groups and samples are taken from each group proportionally.

Example: Ensuring questionnaires are given to the right proportion of each age group in a town.

Data Presentation Techniques

How you present your data is crucial for clear analysis. Different types of data require different presentation methods:

Quantitative Data Presentation

Numerical data can be presented using:

📊 Graphs

Line graphs: Show changes over time or distance

Bar charts: Compare different categories

Scatter graphs: Show relationships between variables

🗺 Maps

Choropleth maps: Show variations across areas using shading

Isoline maps: Connect points of equal value

Flow maps: Show movement or connections

📈 Statistical Methods

Mean, median, mode: Measures of average

Range: Shows the spread of data

Spearman's Rank: Tests correlation between variables

Qualitative Data Presentation

For descriptive or opinion-based data, you might use:

  • Quotes from interviews
  • Word clouds showing frequency of terms
  • Annotated photographs or field sketches
  • Tables summarising responses

Case Study Focus: River Bradshaw Fieldwork

Students from Oakwood School investigated how river characteristics change downstream along the River Bradshaw. They followed the geographical enquiry process:

  1. Question: "How do channel characteristics change downstream along the River Bradshaw?"
  2. Planning: They identified 5 sites along the river and prepared equipment including measuring tapes, flow meters and clinometers.
  3. Data Collection: At each site, they measured channel width, depth, velocity, gradient and sediment size using systematic sampling.
  4. Presentation: They created cross-section diagrams for each site and scatter graphs showing relationships between variables.
  5. Analysis: They found that channel width, depth and discharge increased downstream while gradient and sediment size decreased.
  6. Evaluation: They identified limitations including the fact that measurements were taken on a single day after rainfall, which may have affected results.

Common Fieldwork Challenges and Solutions

Even well-planned fieldwork can face challenges. Here are some common issues and how to overcome them:

⚠ Weather Conditions

Challenge: Unexpected rain or extreme temperatures can affect data collection.

Solution: Check weather forecasts, have contingency plans and use waterproof equipment. Consider how weather might affect your results in your evaluation.

🕐 Time Constraints

Challenge: Running out of time to collect all planned data.

Solution: Prioritise the most important measurements, practice techniques beforehand and create a realistic schedule with buffer time.

Ethical Considerations in Fieldwork

Good geographical enquiry considers the ethical implications of research:

  • Informed Consent: Always explain your research to participants and get their permission.
  • Anonymity: Protect people's identities in questionnaires and interviews.
  • Environmental Impact: Minimise damage to habitats during fieldwork (e.g., avoid trampling vegetation).
  • Safety: Ensure all fieldwork is conducted safely with appropriate risk assessments.

Linking Fieldwork to Geographical Theory

The most successful geographical enquiries connect field observations to wider geographical theories and models. For example:

  • River studies can be linked to the Bradshaw Model of river changes
  • Urban studies might connect to models of urban land use like Burgess or Hoyt
  • Coastal studies can relate to theories of coastal erosion and deposition

Remember, geographical enquiry isn't just about collecting data – it's about using that data to understand the world around us and the processes that shape it. By following the route to geographical enquiry, you'll develop valuable skills in research, analysis and evaluation that will help you throughout your geography studies and beyond!
