The Challenge:
Children were shown two chairs with a gap between them and a toy car. The task was simple: “Build a bridge so the car can cross without falling.” At first, the children worked in pairs for five minutes without any instructions. Many bridges fell down. Some children stacked blocks in a tall tower, some made only one side, and some gave up quickly.
The Turning Point:
After this, I gathered the class and asked: “What happened when your bridge fell? What can we change?” Then I showed one small idea — making the base wider and supporting both sides.
Second Try:
The children went back to build again. This time, most bridges held the car! Children added more supports, used tape, and tried different shapes.
Evidence Collected:
Before the tip, only 3 out of 18 bridges worked. After the tip, 12 out of 18 bridges held the car. A child explained, “It worked because I made two big walls and put blocks across.”
Takeaway:
When children were first allowed to struggle, they explored more ideas. After a short teaching moment, they could apply the idea better and explain why their bridges worked. This small classroom experiment shows how Productive Failure can be applied even with 5–6-year-olds. Instead of just theory, the activity gave us real data, quotes, and photos that can be shared and repeated by other teachers.
