根据学生的学习需要与认知特点,对物理知识呈现的顺序进行调整,是有效的教学选择.进行知识顺序的重构,需要认真分析学生的已有经验,这样的调整才能有的放矢.调整之后的反思与评价,可以让知识顺序的重构更加合理.初中物理教学中,知识呈现的顺序一般来说决定于教材,这里有一个问题值得研究,那就是在教材改革中所调整的知识呈现顺序,体现的到底是什么样的意图.通常情况下,这样的调整都是基于课程标准以 According to the students’ learning needs and cognitive characteristics, the adjustment of the sequence of physical knowledge is an effective teaching choice. The reconstruction of knowledge order requires careful analysis of the students’ existing experience. Such an adjustment can be targeted and adjusted. Reflection and evaluation can make the reconstruction of knowledge order more reasonable. In the junior middle school physics teaching, the order of knowledge presentation is generally determined by the teaching materials. There is a problem worth studying here, that is, the order of knowledge adjustment in the reform of teaching materials. What is the intention of embodying it? Usually, such adjustments are based on curriculum standards.
