Reasoning about Structure and Function: Children's Conceptions of Gears.
Lehrer, Richard; Schauble, Leona
Journal of Research in Science Teaching, v35 n1 p3-25 Jan 1998
Elementary school children were interviewed about how gears move on a gearboard and how they work in commonplace machines. Children's reasoning became more general, formal, and mathematical as problem complexity increased, suggesting that mathematical forms of reason may develop when they provide a clear advantage over simple causal generalizations.
