本文以小學五年級的分數除法單元為例，呈現螺旋變式課程的特色。螺旋變式設計課程的特色是注意課程難點、更有意識地、更有系統地使用「一題多變」與「一題多解」題組，體現概念連接及方法的連接。一題多變的特點是注重循序漸進，同時注重課程的焦點和難點與數學結構的配合。

This article makes use of division of fraction, a topic in Primary 5, as an example to illustrate the features of the spiral “bianshi” curriculum. The main characteristic of the curriculum is its focus on the difficulty of the problem and the more deliberate and systematic use of the “one problem, many variations” and “one problem, multiple solutions” approach to show how concepts and methods are connected. The approach stresses scaffolding of learning and at the same time emphasizes the integration of the curriculum focus and problem difficulty within the context of mathematical structures.
