新版人教版初中物理教科书自2012在全国推广使用。我作为第一批使用本教材的一名物理教师,深感新教材在知识结构、知识内容上更加严谨、合理,并在学生自学以及教师导学方面有更大的发挥空间,充分体现了学生学习上的主体地位,以及教师的主导作用。在一年半的教学实践中有感而发,提出几点感想。首先,八年级上册第一章第一节《长度和时间的测量》在原教材中是安排在九年级。一般的教师在处理这节内容时并没有引起特别的重视,故相对处理得较简单,所用时间也不多。这是因为九年级的学生已 New PEP junior high school physics textbooks since 2012 in the country to promote the use of.
