基于概念性变式的教学设计——以“等比数列”为例

Teaching Design Based on Conceptual Variation—Taking the “Proportional Sequences” as an Example

摘要: 变式教学是教师在教学过程中常用的教学方法，可以培养学生的数学思维，在数学教学中一直扮演着“催化剂”的角色。等比数列是高中生在学习过程中接触的新知识，从概念性变式教学出发，对等比数列的概念提供更多的理解，给学生提供循序渐进的认知过程，帮助学生更好地融合新旧知识。

Abstract: Variable teaching is a commonly used teaching method by teachers in the teaching process, which can cultivate students’ mathematical thinking and play a catalytic role in mathematics teaching. Proportional sequences are new knowledge that high school students come into contact with during the learning process. Starting from the teaching of conceptual variations, we provide more understanding of the concept of proportional sequences, offer students a progressive cognitive process, and help them better integrate new and old knowledge.
