Natural pedagogy is the special relationship between children and adults where children treat adults as helpful, knowledgeable teachers, and adults teach information efficiently and effectively. Unlike simple imitation or trial-and-error learning, natural pedagogy involves intentional teaching and learning exchange. Children learn much more effectively through this interaction than if they were only copying adults exactly.

When adults explicitly teach children about a specific function or task, children focus their attention narrowly on the demonstrated information and limit their exploration of other possibilities. This pedagogical approach restricts children's curious and intrinsically motivated exploratory behaviors. The tradeoff is that while children learn taught information very effectively, they discover fewer alternative solutions or hidden functions on their own.

Researchers randomly assigned children to either a baseline condition, where they explored a toy independently, or a pedagogical condition, where an adult demonstrated one function. The dependent variable was the number of hidden functions discovered. Two independent coders blind to conditions reviewed video recordings and counted discovered functions, with scores ranging from zero to three.

Children in the pedagogical condition, who received instruction, discovered fewer hidden functions than children in the baseline condition who explored freely. This finding demonstrates that teaching focuses children's attention on communicated information while meaningfully limiting their exploration and curiosity. The results highlight a delicate balance between when teachers should instruct versus when children should explore independently.

Self-directed exploration and free-play expose children to wide-ranging educational opportunities, including problem-solving skills and learning about scientific processes like metamorphosis. Children do their best learning when given opportunities to explore on their own. However, exploration becomes inefficient when learning specific methods, such as long division, where direct teaching from an adult is much faster and more effective.

Researchers used video cameras to record each child's interactions with the toy during the testing session. Independent coders who were blind to experimental conditions viewed all videos and counted the number of hidden functions discovered by each child. A t-test was then performed to determine if statistically significant differences existed in the number of discovered functions between the pedagogical and baseline conditions.

Children are inherently predisposed to view adults as helpful and knowledgeable sources of information, and adults instinctively teach children in efficient and effective ways. This mutual recognition of teaching and learning roles occurs without anyone training children or adults to behave this way. This innate pedagogical relationship is one reason young humans are gifted learners who can acquire knowledge much faster than through trial-and-error alone.
