下面将从教材和学情、教法和学法、流程和设计三个方面来谈谈《摩擦力》第一轮复习课的教学设计意图.1教材和学情本节课既是力学的基础,又是对力的概念、平衡力和相互作用力的进一步深化,跟生产和生活有着密切的联系.九年级学生认识事物的特点是从具体的形象思维向抽象逻辑思维过渡.因此,设置真实的情景,让学生身临其境地再现知识,能够进一步加深对摩擦力的理解和应用.
The following will be from the teaching materials and learning, teaching and learning method, flow and design of three aspects to talk about the “friction” of the first round of teaching design intent.1 teaching materials and learning this lesson is not only the basis of mechanics, But also the concept of force, the balance and the further deepening of the interaction force, with the production and life are closely linked.Nine-year students recognize the characteristics of things from the specific image of thinking to the transition of abstract logical thinking.Therefore, to set the real Scenarios, enabling students to reproduce knowledge immersive, to further deepen the understanding and application of friction.
