在数学教学中,不但要关注教与学的方式、方法,还要关注学习的内容,学习时需要对数学内容进行对照、区分、类合与融合四个重要步骤,如何能更快、更系统地帮助教师来设计问题,帮助学生掌握学习内容呢?以《基本不等式求最值》为例,运用变易图式的学习功能,在学习活动的各个阶段对教学内容进行重新整合,在基本不等式求最值的关键特征设计上进行变易,设计适合学生认识规律的导学案,引导学生进行自主学习,让学生成为学习的真正主人,促进学生学习能力的提升。
In mathematics teaching, we should not only pay attention to the ways and methods of teaching and learning, but also pay attention to the contents of learning. In the process of learning, we need to compare, distinguish, classify and integrate the mathematics contents in four important steps: how to make the system faster and more systematic To help teachers to design problems and help students master the learning content? Take the “basic inequality for the best value” as an example, the use of variable schema learning function, in various stages of learning activities to re-integrate the teaching content, in the basic inequality The most important features of the design change, design suitable for students to understand the law of the case, guide students to self-study, so that students become the real master of learning, and promote the improvement of learning abilities.
