苏科版的《电流和电流表的使用》在整个初中物理电学教学过程中的地位大家是有目共睹的,课标和教材对电流并没有给出明确的概念,而是通过活动等形式,帮助学生初步建立对电流的初步认知.电流的概念确实比较陌生、抽象.此时我们需要采取不同的导入策略来达成不同的理想效果.一、基础学生,环环导入对于基础相对薄弱的学生而言,他们由于原先学习构建起的学习习惯、学习能力都相对薄弱.这部分学生接受新知识或 Su Ke version of “the use of current and ammeter” in the entire junior high school physical electrical teaching status we all see, class standard and teaching materials on the current did not give a clear concept, but through activities such as forms to help students preliminary The establishment of the initial understanding of the current.Current concept is really strange, abstract.At this time we need to adopt different import strategies to achieve different ideal results.First, the basic students, the ring into For the relatively weak foundation of the students, They are relatively weak in learning ability due to the learning habits that they build up from the previous study. Some of these students accept new knowledge or
