高三教学将直接面临高考竞争的压力,往往时间紧,任务重,对习题课的课堂效率要求极高。物理命题既涵盖学科知识,又体现学科素养考查,尤其是对理解能力、逻辑推理能力及数学运算能力的综合能力要求较高。因此,探索如何提升班级整体习题课效率就显得极为重要。经过多年课堂教学实践,笔者认为,高三总复习时采用习题科学选编,训练精准高效。不同学生分层精准 High three teaching will face the pressure of college entrance examination competition, often time is tight, heavy tasks, demanding the classroom class efficiency exercises. Physical propositions not only cover the subject knowledge, but also reflect the quality of academic research, in particular, the ability to understand, logical reasoning ability and mathematical computing ability of comprehensive ability demanding. Therefore, it is very important to explore how to improve the efficiency of the class as a whole. After many years of classroom teaching practice, I believe that the general review of high school with selected science exercises, training accurate and efficient.
