课堂教学是初中物理教学的基本形式,随着新一轮课程改革的推进,对课堂教学的有效性愈发关注。提出要构建开放而富有活力的课堂教学,调动全体学生参与学习的积极性,激起学生积极主动地参与学习过程,促进学生知识的主动构建,提高学生的科学素养和整体素质。我结合教学实践对提高初中物理课堂教学的有效性浅谈如下几点体会。一、树立先进的教学观念以往的教学中教师占据主要地位,学生处于次要地位,课堂教学活动完全是教师一个人的,学生被排斥在课堂教学活动之外,只是在观看教师的表演,是课堂教学的听众与看客。这种 Classroom teaching is the basic form of junior high school physics teaching.
