一、教学设计(一)教学设计的思路由于学生在本节课之前刚学习了正余弦函数的图像和性质,我想以此为基础让学生自主探究正切函数的图像和性质,尽量以学生为主体,发挥学生的主动性。因此采取了如下的教学设计思路:教学方法:探究式教学——“变教学为诱思,以诱思促发展”。在教学中,要让学生在学习过程中实现自主学习、合作学习和探究学习,教师充当引导者的角色,引导、帮助学生检视和反思自我,明了要学习什么和获得什么;帮助学生寻找、搜集和利 First, the teaching design (A) the idea of ​​teaching design As students just learned the positive and negative cosine function of the image and nature before the class, I would like to use this as a basis for students to explore the image and the nature of the tangent function, try to students The main body, give full play to students’ initiative. So take the following teaching design ideas: Teaching methods: Inquiry Teaching - “Less teaching as the lure, lure to think and promote development ”. In teaching, we should let students realize autonomous learning, cooperative learning and inquiry learning, the teacher acts as a guide, guide and help students to examine and reflect on themselves, understand what they want and what they get, and help students find and collect And Lee
