Research On Life Teaching Of Chemistry In Senior High School Based On Core Literacy

With the promotion of global education reform,the basic education curriculum of our country is constantly changing.The latest 2017 edition of the Chemistry Curriculum Standard of General Senior High School(hereinafter referred to as the "New Curriculum Standard")points out that we should develop students' core literacy as the basic idea.Teachers should create real situations based on students' experience and life to cultivate innovative spirit and practical ability,which is consistent with the requirements of life teaching.However,the current phenomenon of disconnection between chemistry classroom and life is widespread,which does not meet the requirements of the New Curriculum Standard.With the goal of cultivating core literacy paper studies chemistry life teaching in senior high school,and i have done the following work:On the basis of carding relevant literature,explaining the concepts of core literacy and life teaching,this paper analyzes the necessity from several aspects: the implementation of the requirements of the new curriculum standard,the development of students' core literacy,the improvement of classroom effectiveness and the reform of college entrance examination,which provides a theoretical basis for studing life teaching.The paper investigates the status of life teaching and the implementation of core literacy by questionnaires and interview.Judging from the investigation,students are not very interested in chemistry and lack the consciousness and ability to apply what they have learned.Teachers and students have a positive attitude towards life teaching.Teachers believe that life can promote the cultivation of core literacy,but there is a lack of implementation.Teachers lack professional theoretical knowledge,and the goal of developing core literacy is not implement in place.The attribution analysis is made for the problems in the survey,and some suggestions are put forward to promote the implementation of life teaching: cultivating students' awareness of focusing on life and learning for application,organizing and discussing the implementation of life teaching and core literacy,and strengthening teachers' professional training.According to the results of questionnaire and interview,combined with the requirements of the New Curriculum Standard,this study proposes life teaching strategies based on the core literacy.It includespreparation strategy before class,implementation strategy in the class and consolidation strategy after the class.Specifically speaking,the preparation strategy before class requires that we should grasp the relationship between the teaching materials and life properly,dig into the life materials in the teaching materials,and select the real and typical materials close to the development of the times.We should set up the living teaching objectives scientifically based on the students' life reality.The implementation strategy in class requires that we should use interesting phenomena and common objects in life to introduce teaching content,so as to stimulate students' desire to explore.In the process of classroom explanation,we should pay attention to creating real problem situations,life phenomena and hot issues to carry out exploration activities,so as to develop core literacy.In the class summary,we should return to life and raise application value.Consolidation strategy after class requires we should pay attention to designing life exercises with real situations,and arranging various forms of life practical homework,so as to improve students' ability to apply what they have learned.This paper selects two classes of “protein,oil” and “hydrolysis of salt” in the chemistry textbook of Pep edition to design the life teaching cases based on the core literacy and carry out the practice in class.Teachers in the practice school are asked to use the Diagnostic Evaluation scale of classroom Teaching and evaluate class,and some students are interviewed.The results show that teachers affirmed the help of life teaching to develop students' core literacy.Students' interest in chemistry has significantly increased,and they agree very well with life teaching.They have gradually formed the scientific thinking and exploration consciousness of analyzing problems from the perspective of chemistry,and develop their core literacy.
