Summary
The Costs and Benefits of Natural Pedagogy

Children have many tools they use over the course of development to learn from adults. Perhaps the earliest tool is imitation, simply copying what they see an adult do or say. However, children actually learn much more effectively than one might expect if they were only imitating. This is because, when it comes to learning and teaching, children and adults have a special relationship. Children treat adults as if they are helpful and knowledgeable teachers, and adults teach children information in a manner that is usually efficient and effective. Through these interactions, children can learn much better than if they were simply using trial-and-error or copying adults exactly. This way of interacting is referred to as natural pedagogy, and it is one of the reasons that young humans are gifted learners.
One of the most impressive aspects of natural pedagogy is that no one teaches adults how to be good teachers, and children treat adults as teachers without having to be trained to do so. However, natural pedagogy also entails costs. Children are curious and intrinsically motivated to explore, so children do some of their best learning when given opportunities to learn and explore on their own. Thus, the result of natural pedagogy is that children learn information taught to them very effectively, but explicit teaching restricts their curious, exploratory behaviors. There is a tradeoff between efficient learning and self-driven exploration.
This video demonstrates the method by which Elizabeth Bonawitz, Patrick Shafto, and colleagues1 showed the effects of natural pedagogy on young learners.
Recruit approximately 40 healthy 4-year-olds with no history of developmental disorders. For the purposes of this demonstration, only two children are tested (one in each condition). Larger sample sizes are recommended when conducting any experiments.
1. Data collection
- Gather the necessary materials.
- Acquire a novel device with four different non-obvious functions. For example, the device used by Bonawitz and colleagues1 had a hidden button that made a light
Children in the pedagogical condition typically discover fewer of the hidden functions of the device than children in the baseline condition (Figure 1). Children taught about the device also usually spend less time playing with it, and they focus their play on the function taught to them by the experimenter, even if they discover other functions. Taken together, these findings suggest that teaching children focuses their attention on the communicated information and meaningfully limits their exploration
This experiment demonstrates that there is value in letting children explore their world on their own, and that explicitly teaching children can meaningfully limit their curiosity in some situations. In particular, there is a growing body of evidence that children can learn as effectively, if not more effectively, through free play and self-directed exploration than through explicit instruction. That said, teaching is not always a bad thing, and these results must be considered in the broader context of children’s
