SimCalc MathWorlds for the mathematics of change
Jeremy Roschelle, James J. Kaput · Communications of the ACM · 1996
IMCALC'S mission is to enable all children to learn the mathematics of change, beginning in the early grades.This mathematics is conventionally sequestered in elite calculus courses after many prerequisites, denying many students access to the critically important ideas of rate, accumulation, approxima-tion, limit, and mean value.We aim to teach these essential ideas to children as part of a restructured mathematics curriculum for children 5 years to 18 years of age.By supporting the conceptual growth of powerful ideas, we therefore prepare all citizens to describe, discuss, design, and analyze the processes of change.
