从可绘图计算器辅助教学的一个例子所想到的田载今（人民教育出版社１００００９）计算工具的进步必然带动数学教学的改革．例如，６０年代以前，有关对数计算尺的内容是中学数学的必学内容．然而，随着电子计算器的问世和广泛使用，现在的中学数学教学中已经找不到计算尺... The progress of computational tools proposed by Tian Zaijin (People’s Education Press, 100009), which is thought to be an example of the drawing-assisted calculator-assisted teaching, will inevitably lead to the reform of mathematics teaching. For example, before the 1960s, the content of the logarithmic slide rule was a must for middle school mathematics. However, with the advent and widespread use of electronic calculators, there is no slide rule in mathematics teaching in middle schools...
