Sampling Strategies in Fieldwork

Active learning works for this topic because fieldwork skills are best learned by doing. Students need repeated, structured practice with real tools and scenarios to build confidence and competence in choosing appropriate sampling methods.

Activity 01

• Stations Rotation
• 60 min · Small Groups

Stations Rotation: Fieldwork Tool Kit

Set up stations with different tools (e.g., a flow meter, an environmental quality survey, and a decibel meter). Students spend 10 minutes at each, practicing the technique and identifying one potential source of error.

Compare the advantages and disadvantages of random, systematic, and stratified sampling.

Facilitation Tip

For the Station Rotation, set up each tool station with clear instructions and a sample data sheet so students can focus on technique rather than setup.

What to look for

Present students with three hypothetical fieldwork scenarios (e.g., measuring river discharge, surveying vegetation types in a park, assessing housing density in a neighborhood). Ask them to write down which sampling strategy (random, systematic, or stratified) would be most appropriate for each and provide a one-sentence justification.

Activity 02

• Inquiry Circle
• 45 min · Small Groups

Inquiry Circle: Qualitative vs. Quantitative

Groups are given a research goal (e.g., 'How do people feel about the new park?'). They must design one quantitative method (e.g., a 1-5 scale survey) and one qualitative method (e.g., an unstructured interview) to answer it.

Justify the selection of a specific sampling strategy for a given fieldwork investigation.

Facilitation Tip

During the Collaborative Investigation, provide a Venn diagram template to help students organize their comparisons of qualitative and quantitative data types.

What to look for

Pose the question: 'Imagine you are studying the impact of traffic noise on residents in a town with a busy main road and quieter residential streets. How might sampling bias occur if you only sample along the main road? What sampling strategy would you use to ensure a fair representation of the town's residents?'

Activity 03

• Think-Pair-Share
• 20 min · Pairs

Think-Pair-Share: The Power of the Pilot Study

Students discuss with a partner why it's a good idea to test their data collection sheets on a small scale before doing the full investigation. They share one thing they might change after a pilot study.

Analyze how sampling bias can affect the reliability and validity of geographical data.

Facilitation Tip

In the Think-Pair-Share activity, give students a one-paragraph case study to anchor their discussion of pilot studies in real-world scenarios.

What to look for

Ask students to define one sampling technique in their own words and explain one situation where it would be the best choice, and one situation where it would be a poor choice. They should also identify one potential source of bias for the technique they defined.

A few notes on teaching this unit

Teachers should emphasize that fieldwork is iterative. Start with simple scenarios, then gradually increase complexity as students master basic techniques. Avoid overwhelming students with too many tools at once. Use real-world examples to illustrate how sampling choices directly impact data quality and conclusions.

Successful learning looks like students confidently selecting sampling strategies based on research questions, recognizing the strengths of different data types, and articulating how bias can affect results. They should also demonstrate teamwork and adaptability when using fieldwork tools.

Watch Out for These Misconceptions

• During the Station Rotation activity, watch for students who collect data without a clear research question. Redirect them by having them write a research question on their data sheet before starting to use any tools.
