Active learning ideas

Building a National Defence Force

Active learning works because this topic requires students to connect historical decisions with human experiences. Simulations and discussions help students move beyond abstract facts to understand why a citizen army was essential for Singapore's survival and identity.

Activity 01

• Simulation Game
• 40 min · Small Groups

Simulation Game: The Teamwork Challenge

Students must complete a task (e.g., moving a 'heavy' object using only strings) that requires perfect coordination and communication. They discuss how this kind of teamwork is the heart of National Service and why every person's role matters.

Explain the critical reasons for Singapore to build its own independent defense force.

Facilitation Tip

During the Teamwork Challenge simulation, assign roles that require interdependence so students experience firsthand how tasks cannot be completed without cooperation.

What to look for

On a slip of paper, ask students to write two reasons why Singapore needed its own defense force after independence and one way National Service helps build national identity.

Activity 02

• Gallery Walk
• 30 min · Small Groups

Gallery Walk: The Many Faces of NS

Display photos of soldiers, police officers, and firefighters in training. Students move around to identify the different ways people serve the country and write down one 'value' (e.g., bravery, resilience) they see in each photo.

Analyze the concept of National Service and its role in fostering national identity and resilience.

Facilitation Tip

For The Many Faces of NS gallery walk, place images of NS personnel from different forces in visible locations to reinforce that national security includes multiple roles.

What to look for

Facilitate a class discussion using the prompt: 'Imagine you are a young Singaporean in the 1960s. Why would the idea of National Service be important to you and your family?' Encourage students to connect personal safety with national security.

Activity 03

• Think-Pair-Share
• 20 min · Pairs

Think-Pair-Share: Why Everyone?

Students discuss in pairs why the government wanted *everyone* to do NS instead of just hiring a small group of professional soldiers. They share their ideas on how meeting people from different backgrounds during NS helps to unite the country.

Evaluate how the SAF contributes to Singapore's sovereignty and regional stability.

Facilitation Tip

In the Think-Pair-Share on 'Why Everyone?', set a timer for each step to keep discussions focused and ensure all students contribute their thoughts.

What to look for

Present students with a scenario: 'A neighboring country is experiencing political instability.' Ask them to explain in one sentence how the SAF contributes to Singapore's security in such a situation.

A few notes on teaching this unit

Start by framing NS as a civic responsibility rather than just a military requirement. Use primary sources from the 1960s, like speeches by Lee Kuan Yew, to show how leaders communicated the urgency of self-defense. Avoid treating NS as a standalone policy—instead, connect it to Singapore's broader narrative of survival and identity.

Successful learning looks like students explaining why National Service (NS) was necessary for Singapore's security and how it builds bonds across diverse groups. They should articulate the value of teamwork, shared responsibility, and national unity as core outcomes of NS.

Watch Out for These Misconceptions

• During the Teamwork Challenge simulation, watch for students who focus only on the combat aspect of NS.

  Use the debrief to highlight how the simulation’s goals—cooperation, communication, and trust—mirror the real-life benefits of NS beyond soldiering.

• During The Many Faces of NS gallery walk, watch for students who assume NS is limited to the army.

  Point to images of police officers, firefighters, and medics to emphasize that national security includes diverse roles, and ask students to note these in their reflections.
