From a Historical Observation to a Theory of Calculus Education
摘要
It all started with the question, “How might Newton have understood a function’s graph so that he saw the Fundamental Theorem of Calculus when viewing it?” Puzzling about that question led to a convergence of radical constructivism, quantitative reasoning, and insights into students’ understandings of variation and covariation that eventually formed a theory of calculus learning and teaching.
