课改的核心在课堂,课堂的有效在设计。只有认真设计好教学环节,才能促使课堂教学的有效性落到实处,才能真正落实新课标所倡导的“使学生从学会走向会学”的理念。下面我以北师大版八年级数学“探索多边形的内角和”为例设计教学环节并进行解析。第一环节:明确目标【内容】1.探索多边形内角和公式及其内角和公式的应用;2.探究多边形内角和公式推导的基本思想——从特殊到一般及转化的数学思想。【解析】引导学生明确学习目标,圈画重点字、词,使学生由无
The core of curriculum reform in the classroom, the effective design of the classroom. Only by seriously designing the teaching links can we effectively carry out the effectiveness of classroom teaching and implement the concept of “enabling students to learn from learning”. Now I use the eighth edition of the National Taiwan Normal University mathematics “to explore the polygon angle and ” as an example to design teaching and analysis. The first link: a clear goal [Content] 1. To explore the application of polygon internal angles and formulas and their internal angles and formulas; 2. To explore the basic idea of polygonal internal angle and formula derivation - from special to general and conversion mathematical ideas. [Analysis] To guide students to clear learning objectives, circle painted key words, words, so that students from nothing
