From the site but I’ll summarize further: Do children construct their knowledge of the world like scientists?
If so you want Theory-theory. If not, there are alternatives, briefly covered on that site but more is available elsewhere.
“The Theory-Theory relies heavily on the notion that what children do in constructing their knowledge of the world is quite literally like what scientists do in producing, testing, and revising the theories that constitute scientific knowledge. This implies that there is substantial cognitive continuity across development, so that infants and young children, along with older children and adults, employ the same theory-construction mechanisms that operate on prior theoretical representations plus new evidence to produce revised and, with luck, improved theories.
Many have challenged this picture on the grounds that what children do is not in fact sufficiently similar to what scientists do for them to be seen as instances of the same cognitive or epistemic process. “
