摘要: Publisher Summary There is a lot of anecdotal and observational evidence for the extensive role visuals diagrams in practice mathematics. The classical book Hadamard records recollections number well-known mathematicians on how they made significant discoveries. Brown surveys this over longer period from more philosophical point view. interviews current by Mathematics educator Burton have found conversation about intuition. This kind word that people use when there are no other words—for example, process visual but not sharp form. These differences gaps between experience teacher student important understanding why classroom can fail. Many individuals groups recognized visualization has potential to improve learning or performance mathematics education, then been disappointed at actual observations difficulties classroom. Dynamic geometry programs, such as Cabri Geometrie, Geometers SketchPad, Cinderella now used teaching school geometry.
