Research On The Teaching Strategy Of "Ion Reaction And Balance In Aqueous Solution" From The Perspective Of Core Literacy

Cultivating students’ key competencies is the developing trend of basic educational reform,as an important part of key competencies,chemical key competencies centrally embody the educational value of Chemistry discipline."Ion reaction and equilibrium in aqueous solution" is the important teaching content of high school chemistry,and also the key to develop students’ chemical key competencies.This paper is based on the new curriculum standard,develops students’ key competencies in chemistry as the aim,takes the knowledge of "ion reaction and equilibrium in aqueous solution" as the carrier,on the basis of theoretical research,adopts situational strategy,analog strategy,intuitive strategy,modeling strategy and integrated strategy for teaching practice,the teaching effect was analyzed through experimental study,interview and questionnaire,and enables students to master the knowledge of ion balance in aqueous solution while improving the core quality of chemistry,the practice provided practical suggestions for improving teaching quality and cultivating students’ chemistry core quality.
