ABSTRACT We demonstrate the power of Variation Theory as an analytical tool used to understand the underlying conceptual structure of mathematics lessons taught by English primary school teachers. We study excerpts of three lessons that are posted on a professional website. We show how lesson analysis using variation allows us to focus on what is made available to be learnt in the lesson excerpts. We identify some differences in their use of dimensions of variation and the associated ranges of change and discuss how suitable patterns of variation and invariance might differ according to the nature of the learning focus. We reflect on the value of our analytical approach.

学习机会：使用变体分析英格兰小学数学教学范式转变的例子

摘要 我们展示了变异理论作为一种分析工具的力量，用于理解英语小学教师教授的数学课程的基本概念结构。我们研究发布在专业网站上的三节课的摘录。我们展示了使用变体的课程分析如何让我们专注于课程摘录中可供学习的内容。我们确定了他们在使用变异维度和相关变化范围方面的一些差异，并讨论了根据学习重点的性质，合适的变异和不变性模式可能如何不同。我们反思我们分析方法的价值。
