Researchers compared two groups of trainee preschool teachers: one trained through a systems-thinking approach (understanding how parts connect and why they work), and one trained traditionally. Both groups then created technology and engineering projects. The question was simple but important: how do we actually know if teachers have learned?
Most training programmes measure learning by looking at what teachers make—the quality of their projects or prototypes. But this study suggests that's incomplete.
Teachers who think about systems show deeper understanding
When researchers examined how each group wrote about and explained their work, the difference was striking. Teachers trained with systems thinking showed more diverse, interconnected reasoning. They could connect ideas, see different angles, and explain how parts fit together. The traditional group focused more narrowly on what systems did and how they were organised.
The key finding: written reflections revealed this difference clearly. Teachers' ability to explain their thinking—not the quality of their finished product—showed whether they truly understood the material.
A beautiful project doesn't guarantee real learning
For Singapore families, this has a practical implication. A well-constructed robot or impressive model from your child's nursery doesn't necessarily mean the teacher understands how or why it works. If teachers haven't learned to think systemically, they may simply be following instructions or focusing on the end result.
This matters because young children learn through what teachers model. A teacher who can explain connections and reasoning teaches deeper thinking than one who focuses only on building something impressive.
What to ask your child's nursery
- Request information about teacher training: does it include systems thinking and reflection, or mainly project-building techniques?
- When your child brings home a tech project, ask the teacher how they encouraged thinking about why and how things work, not just the final product.
- Look for nurseries that emphasise explanation and reasoning alongside hands-on activities in their technology curriculum.
