Active learning ideas

Public Health and Sanitation

Active learning works well for this topic because students need to connect historical health challenges to human experiences. By participating in simulations and discussions, students move beyond dates and facts to understand how people lived and solved problems in early Singapore.

Simulation Game: The Disease Detective

Students are given a map of a fictional 1900s neighborhood with 'sick' markers. They must look for 'clues' (e.g., a dirty well, stagnant water, a crowded room) to figure out why people are getting sick and suggest one 'fix' for each problem.

Identify the major public health issues prevalent in growing colonial Singapore.

Facilitation Tip

For the simulation, assign specific roles (e.g., resident, sanitary commissioner) so students engage with different perspectives on public health decisions.

What to look for

Students will receive a card with a picture representing either a public health challenge (e.g., crowded housing, dirty river) or a public health solution (e.g., hospital, clean water pipe). They must write one sentence explaining the connection between their picture and public health in early Singapore.

Activity 02

• Gallery Walk
• 30 min · Small Groups

Gallery Walk: Tools of the Trade

Display images of early medical tools, a 'night soil' bucket, and an old water standpipe. Students move around to guess what each item was used for and how it helped (or didn't help) keep the town healthy.

Explain the measures implemented by the authorities to improve sanitation and disease control.

Facilitation Tip

During the gallery walk, place primary source images at eye level and ask students to note one detail about each image before moving on.

What to look for

Pose the question: 'Imagine you are a resident of colonial Singapore. What is one health problem you might face, and what is one thing the government did to help?' Students write their answers on mini whiteboards for a quick visual check of understanding.

Activity 03

• Think-Pair-Share
• 20 min · Pairs

Think-Pair-Share: Clean Water Challenge

Students discuss how their day would change if they had to walk 10 minutes to a public tap to get all their water for drinking and washing. They share their ideas on why having water 'in the house' is such a big improvement for health.

Assess the effectiveness of early healthcare initiatives in safeguarding public well-being.

Facilitation Tip

In the Think-Pair-Share, provide a timer for the pair discussion and require each student to share one idea before moving to the whole-class discussion.

What to look for

Facilitate a class discussion using the prompt: 'How did the actions taken to improve sanitation in early Singapore directly impact the lives of ordinary people? Give at least two examples.'

A few notes on teaching this unit

Teach this topic with a focus on cause and effect, using primary sources to show how health problems were identified and addressed. Avoid presenting public health improvements as inevitable successes; instead, highlight the trial and error involved in early sanitation efforts. Research suggests that connecting past health crises to present-day issues (e.g., mosquito control, clean water access) helps students see relevance and deepens their understanding of progress over time.

Successful learning looks like students explaining health challenges with historical evidence and describing how public health improvements affected daily life. They should also articulate the limitations of past solutions compared to modern practices.

Watch Out for These Misconceptions

• During the Disease Detective simulation, watch for the idea that people in the past didn’t care about cleanliness. Redirect by pointing to the simulation’s evidence cards, which show how crowded housing and poor waste disposal created ideal conditions for disease, regardless of personal habits.

  During the Disease Detective simulation, explicitly ask students to note how environmental factors, like stagnant water or shared latrines, contributed to illness, not individual cleanliness choices.

• During the Think-Pair-Share Clean Water Challenge, watch for the explanation that malaria was caused by 'bad air.' Redirect by having students reference the activity’s timeline, which includes the 1890s discovery of mosquitoes as the vector, to correct the misconception with scientific evidence.

  During the Think-Pair-Share Clean Water Challenge, provide a snippet from a 19th-century medical journal that mentions 'bad air' and ask students to contrast it with a later source that names mosquitoes, making the shift in scientific understanding explicit.
