1微课目标本微课以相交线和平行线内容为载体,让学生体会到平时学习的两线相交的基本模型和“三线”八角的基本模型是解决这些复杂问题的基础,让学生体会到“以退为进”这种解题策略——将复杂的图像“退”化为简单图形,然后从简单图形出发解决复杂问题,从而增强学生突破难题的信心和决心,使学生不仅学到知识,更能感受到数学家的智慧。2微课设计2.1学习数学家名言PPT展示华罗庚先生的名言:“善于‘退’,足够地‘退’,‘退’到最原始而不失重要的地方,是学好数
1 Micro-Lesson Sample This micro-class takes the intersecting line and parallel line as the carrier to let students understand that the basic model of two-line intersection and the basic model of ”three-line“ and ”star anise“ are the basis for solving these complicated problems, Experience the solution to the problem of ”retreat into something“ - turn complex images into simple graphics, and then solve complicated problems from simple graphics, so as to enhance students’ confidence and determination in breaking through difficult problems, So that students not only learn the knowledge, but also feel the mathematician’s wisdom. 2 micro-class design 2.1 learning mathematician famous words PPT show Mr. Hua Luogeng’s famous quote: ”good at " back, ’enough’ back ’,’ back ’to the most primitive yet important place,
