Active learning ideas

Emerging Infectious Diseases: Global Threats

Active learning works for emerging infectious diseases because the topic demands synthesis of ecological, social, and biological systems. Students must connect abstract drivers like deforestation to concrete outbreak outcomes, which hands-on activities make visible and memorable.

Activity 01

• Jigsaw
• 50 min · Small Groups

Jigsaw: Zoonotic Outbreaks

Divide class into expert groups on cases like COVID-19, Ebola, and Nipah virus; each group researches one factor (e.g., deforestation) and its role. Regroup into mixed teams to share findings and create a class infographic. Conclude with whole-class synthesis.

Analyze the environmental and societal factors that contribute to the emergence of new pathogens.

Facilitation Tip

During the Case Study Jigsaw, assign each group a different zoonotic outbreak and provide structured guiding questions to focus their comparative analysis.

What to look for

Pose the question: 'Considering recent outbreaks, which societal factor (e.g., urbanization, international travel, climate change) do you believe poses the greatest immediate risk for a new pandemic, and why?' Allow students to share their reasoning and debate different perspectives.

Activity 02

• Simulation Game
• 40 min · Pairs

Simulation Game: Pathogen Spread Model

Provide dice or cards representing transmission factors (travel, resistance); students in pairs simulate outbreaks over 'generations,' tracking variables like mutation rates. Adjust parameters and graph results to predict vaccine challenges.

Predict the challenges in developing effective treatments and vaccines for rapidly evolving viruses.

Facilitation Tip

In the Pathogen Spread Simulation, limit initial parameters to 5 variables so students can isolate the impact of each factor on transmission speed.

What to look for

Provide students with a short news clipping about a hypothetical new infectious disease. Ask them to identify at least two factors from the lesson that likely contributed to its emergence and one challenge in developing a treatment.

Activity 03

• World Café
• 45 min · Pairs

Debate Carousel: Factor Prioritization

Post stations with factors (climate, globalization); pairs rotate, debating and ranking their impact on emergence with evidence cards. Vote class-wide on top threats and justify.

Evaluate the role of zoonotic spillover events in the origin of many human pandemics.

Facilitation Tip

For the Debate Carousel, rotate student roles every 3 minutes to ensure all voices contribute and time pressure builds clarity in argumentation.

What to look for

In small groups, students create a concept map linking environmental factors, human activities, and disease emergence. They then swap maps and provide feedback on the clarity of connections and the inclusion of key vocabulary terms.

Activity 04

• 35 min · Small Groups

Data Mapping: Global Hotspots

Using online tools or printed maps, small groups plot recent outbreaks, overlay environmental data, and hypothesize drivers. Present findings to class for peer critique.

Analyze the environmental and societal factors that contribute to the emergence of new pathogens.

Facilitation Tip

While students map Global Hotspots, provide a color-coded legend to help them link environmental, demographic, and public health data visually.

What to look for

Pose the question: 'Considering recent outbreaks, which societal factor (e.g., urbanization, international travel, climate change) do you believe poses the greatest immediate risk for a new pandemic, and why?' Allow students to share their reasoning and debate different perspectives.

A few notes on teaching this unit

Teach this topic by moving from concrete examples to abstract systems. Start with case studies to build empathy and context, then use simulations to reveal hidden variables. Avoid overwhelming students with too many factors at once—build complexity gradually through structured layers. Research shows role-play and mapping activities improve retention of complex systems by up to 40% compared to lectures alone.

Successful learning looks like students tracing pathogen jumps across ecosystems, prioritizing risk factors with evidence, and explaining how human choices shape disease spread. Their work should show cause-and-effect reasoning, not just recalling facts.

Watch Out for These Misconceptions

• During the Case Study Jigsaw, watch for students attributing outbreaks solely to hygiene practices in affected regions.

  Use the jigsaw’s structured prompts to redirect attention to the provided ecological and demographic data, asking groups to identify deforestation rates or wildlife trade patterns that preceded each outbreak.

• During the Pathogen Spread Simulation, watch for students assuming vaccine development will always catch up to viral mutations.

  Have students run the simulation with high mutation rates and observe how rapidly vaccine efficacy declines, then require them to propose realistic timelines for vaccine deployment.

• During the Debate Carousel, watch for students treating all transmission routes as identical.

  Use the rotation structure to assign each group a specific pathogen and its transmission pathway, then require them to defend why their route demands unique control strategies.
