当前初中物理教学中存在着两个较大的困惑:一是新课程标准教学课时不足严重;二是学生学习动力的严重缺乏。笔者经过几年的教学尝试,认为通过:1以学定教,合理整合教材,引领学生知识建构;2问题引领,激发学生的内在学习动力;3精讲多悟,注重实质,才能使学生在有限的课时内,乐知、好知,最终将知识转化为能力,能力内化提升为素质。 At present, there are two big confusion in the physics teaching of junior high school: one is that the new curriculum standard teaching class is not enough; the other is the serious lack of students’ learning motivation. After several years of teaching attempts, I believe that: 1 to learn to teach, rational integration of teaching materials, leading students to construct knowledge; 2 problems lead to stimulate students’ intrinsic learning motivation; Within a limited period of time, music knowledge, good knowledge, and ultimately knowledge into ability, internalization of ability to enhance quality.
