Active learning ideas

Epidemiology and Health Geography

Active learning works for this topic because students need to see how invisible health data connects to real places they recognize. When teenagers map food access or trace disease spread on a bus route map, abstract concepts like equity and infrastructure become visible and personal.

Mapping Activity: Food Deserts in Our Region

Using USDA food access research atlas data or a simplified printout, student pairs identify food desert census tracts in their county or a nearby urban area. They overlay the map with median income data and calculate the correlation. Pairs present one finding to the whole class, and the class discusses what policy could change the pattern.

Analyze how globalization accelerates the spread of pandemics.

Facilitation Tip

For the Mapping Activity, pre-select a mix of urban and suburban census tracts so students see both dense food deserts and surprising gaps in wealthy areas.

What to look for

Pose the question: 'Imagine you are a public health advisor for a city. What geographic data would you collect to understand why diabetes rates are higher in one neighborhood than another, and what policy recommendations might you make?' Facilitate a class discussion where students share their ideas and justify their reasoning.

Think-Pair-Share: How Does Globalization Spread Disease?

Show students a simplified flight network map and ask: 'If a new respiratory illness appeared in a major hub city today, trace three paths it could take in the first 72 hours.' Students sketch individual routes, compare with a partner, then map the fastest paths on the class whiteboard. Follow with data from the 2003 SARS spread for comparison.

Explain what a 'food desert' is and how it affects public health.

Facilitation Tip

During the Think-Pair-Share, assign pairs so that one student starts with air travel data and the other with shipping routes to force comparison of different globalization pathways.

What to look for

Provide students with a map showing the locations of fast-food restaurants and full-service grocery stores in a hypothetical city. Ask them to identify two areas that could be considered food deserts and explain their reasoning based on accessibility and proximity to healthy food options.

Activity 03

• Jigsaw
• 45 min · Small Groups

Jigsaw: Geographic Disease Persistence

Assign four expert groups each a disease that persists in specific geographic regions: malaria, Chagas disease, river blindness, and cholera. Each group reads a one-page brief identifying the geographic conditions that sustain the disease. Groups then reform into mixed teams of four and each expert teaches their disease. The class identifies shared geographic factors.

Predict why certain diseases persist in specific geographic regions.

Facilitation Tip

In the Case Study Jigsaw, structure expert groups around geographic drivers (climate, policy, migration) so students must integrate multiple causes for disease persistence.

What to look for

Students write a short paragraph explaining how globalization has changed the way diseases spread compared to 100 years ago, referencing at least one specific mode of modern transportation.

Activity 04

• Gallery Walk
• 30 min · Small Groups

Gallery Walk: Healthcare Access Deserts

Post maps and statistics showing hospital and primary care shortages in rural US counties alongside urban underserved areas. Students rotate with sticky notes, adding one observation and one question per station. The class synthesizes observations to identify which geographic factors most reliably predict poor healthcare access.

Analyze how globalization accelerates the spread of pandemics.

Facilitation Tip

For the Gallery Walk, post healthcare access maps at different scales—city, county, state—so students notice how zooming in changes what counts as a 'desert'.

What to look for

Pose the question: 'Imagine you are a public health advisor for a city. What geographic data would you collect to understand why diabetes rates are higher in one neighborhood than another, and what policy recommendations might you make?' Facilitate a class discussion where students share their ideas and justify their reasoning.

A few notes on teaching this unit

Teachers approach this topic by making geography the lens, not the backdrop. Avoid starting with definitions of epidemiology before students experience the data firsthand. Instead, let students notice patterns on maps, then name the concept. Research shows that when students experience the 'why' before the 'what,' they retain systemic thinking longer and resist individual-level explanations of complex health problems.

Successful learning shows when students connect geographic patterns to social causes rather than blaming individuals. Students should explain how policy, income, and environment shape health outcomes in specific neighborhoods.

Watch Out for These Misconceptions

• During Mapping Activity: Food Deserts in Our Region, watch for students to claim people in food deserts 'don't like healthy food.'

  During Mapping Activity: Food Deserts in Our Region, redirect students to overlay commute times from census blocks using the provided transit layer. Ask them to calculate walking distances to the nearest store and note whether public transit serves those routes.

• During Think-Pair-Share: How Does Globalization Spread Disease?, watch for students to say pandemics spread randomly.

  During Think-Pair-Share: How Does Globalization Spread Disease?, hand pairs a map of 2009 H1N1 cases overlaid on global flight paths. Ask them to trace the first three cities with outbreaks and explain why those hubs appeared in that order.

• During Case Study Jigsaw: Geographic Disease Persistence, watch for students to blame lack of hospitals or clinics as the main cause.

  During Case Study Jigsaw: Geographic Disease Persistence, require each expert group to present one environmental or policy cause on a sticky note before listing medical resources. Ask them to place the sticky notes on a world map to show non-medical drivers clustered in specific regions.
