高中数学中,每一章节开始的数学概念,通常是通过列举生活、生产或科技的相关实例,归纳问题的本质属性,推演或介绍数学概念,随着学习的深入,每一章节都有一些纵横联系的网结点,有关概念抽象度很高,内涵丰富,外延广泛,初学者认识和理解难度相对较大,较短时间内,较难做到深刻理解,熟练掌握,容易留下学习中的盲点,是形成学科学习障碍的重要因素之一.现以复合函数,直线的倾斜角和斜率的关系,三角函数图像变换为例,运用几何画板技术,介绍数学概念教学思路之一.制作模型,类比迁移数学概念教学思路.
In high school mathematics, the mathematical concepts that begin with each chapter are usually made by enumerating examples of life, production, or technology, summarizing the essential attributes of the problem, deducing or introducing mathematical concepts, and as each study progresses, each chapter has Some of the nodes connected in vertical and horizontal directions have a high degree of conceptual abstraction, rich connotation, extensive extension, relatively high level of understanding and understanding for beginners, difficulty in understanding and mastering in a short period of time, and easy learning Is one of the most important factors in the formation of learning disability.According to the composite function, the relationship between the inclination and slope of a straight line, and the transformation of trigonometric functions as an example, this paper introduces one of the concepts of mathematics teaching by using geometric drawing board technology. Model, analogy transfer mathematical concept teaching ideas
