串联电路电流规律的前概念转变措施

Research of Transformation Measure of Pre-conceptions Series Circuit Current Rules

通过测试、实验、调查问卷、访谈,结合自己的教学经验,总结出学生在串联电路的电流规律方面存在的4个典型的前概念,分析学生头脑中前概念产生的原因,最后有针对性地提出转变前概念的三个教学措施：学生互相讨论说出已有的前认知,通过探究实验促进学生转变概念,利用随机通达教学强化巩固科学概念。

This research uses lots of examinations,experiments,investigates,interviews and teaching experience to get 4 typical pre-conceptions in the series circuit current rules,analyzes the characteristics and reasons of the pre-conceptions.On this basis,I put forward to the teaching strategies of transforming the pre-conceptions accordingly：the students discuss with each other and give their pre-conceptions;improving the student＇s transformation of pre-conceptions by inquiring;enable the students to master the science conceptions correctly by random teaching.
