新的课程标准要求学生改变学习方式,改被动接受知识为自主探究知识,得出结论。为了能够帮助学生完成这一学习方式,教师须在课堂上大胆设置情境,让学生有自主探究的空间。依据这一理念,笔者在《带电粒子在匀强磁场中的运动》这节课上,精心设计每一个教学环节,积极创设问题情境,激发学生的探究动机,让学生主动学习,自主探究,得出结论。 The new curriculum standards require students to change their learning styles and change their knowledge of passive learning to explore knowledge independently to reach a conclusion. In order to help students to complete this learning method, teachers should boldly set the situation in the classroom, so that students have the space to explore themselves. According to this idea, the author carefully designed each teaching link in the course of “the movement of charged particles in even and strong magnetic field”, actively created the problem situation, stimulated students’ inquiry motivation, and let students take the initiative to study and explore independently Conclusion.
