通过“光的直线传播”教学片段为例谈初中物理课堂教学中如何搭建思维阶梯,促进学生反思实验。教学中教师引导学生寻找新的实验策略,对实验障碍进行反思,最终实现课堂的生成。并在得到结论的基础上继续反思,寻找新的方式来验证结论,通过反思调动学生的积极性,促进学生创新能力的发展。教师要努力做到创设合适的物理情景,让学生有思可反;建立和谐民主的课堂,让学生有思敢反;允许学生实验的失败,让学生有思再反。
How to Set Up the Thinking Ladder in Junior Middle School Physics Teaching through the Teaching of “Light - Propagated Lines of Light” to Promote the Students’ Reflective Experiment. In teaching, teachers guide students to find new experimental strategies, reflect on experimental obstacles, and finally realize classroom formation. On the basis of the conclusion, we should continue to reflect on it, look for new ways to verify the conclusion, motivate the enthusiasm of students through reflection, and promote the development of students’ innovative ability. Teachers should strive to create a suitable physical scenario, so that students think of ideals; establish a harmonious and democratic class, so that students think smartly; allow students to experiment failure, so that students think twice.
