新一轮课程改革倡导学生自主、合作、探究的学习方式。在旧教材的教学中,如何引导学生自主探究,教师的教学理念的转变是关键。笔者在《光的直线传播》的教学中,采用探究教学的形式,让学生自行设计探究的过程,使教学过程有如山中流动的溪水,充满生机,充满活力,富于创新。 The new round of curriculum reform advocates students’ autonomy, cooperation, and inquiry learning. In the teaching of old teaching materials, how to guide students to explore independently, the change of teachers’ teaching philosophy is the key. In the teaching of “The Linear Propagation of Light,” the author uses the form of inquiry teaching to allow students to design their own inquiry process so that the teaching process is like the stream flowing in the mountains, full of vitality, full of vitality, and full of innovation.
