课程改革的目标之一是改革落后的教学方式与学习方法,引导学生积极探究、勇于实践,培养学生发现、分析和解决问题的能力。笔者在实践中不断尝试探究性课堂教学方式,现将教学人教版选修3-4第十三章第一节“光的折射”探究性教学实录叙述如下。一、提出问题【教师活动】1.Flash动画:射鱼的实验。2.复习初中光学的反射和折射规律。3.明确研究的课题—入射角(θ1)与折射角(θ2)的定量关系。
One of the objectives of the curriculum reform is to reform backward teaching methods and learning methods, guide students to actively explore and bravely practice, and cultivate students’ ability to discover, analyze, and solve problems. In the practice, the writer constantly tries to explore the classroom teaching method. Now the pedagogic version of the pedagogical version of the pedagogy of the 3-4 chapters of the Thirteenth chapter is the following. First, ask questions [teacher activities] 1.Flash animation: shooting fish experiments. 2. Review the reflection and refraction laws of junior high school optics. 3. A definite research subject—a quantitative relationship between the angle of incidence (θ1) and the angle of refraction (θ2).
