Research On Cultivation Of Chemical Core Literacy Of Senior Middle School Students From The Perspective Of Situational Teaching

In 2014,when the Ministry of Education issued the opinions of the Ministry of education on comprehensively deepening the curriculum reform and implementing the fundamental task of cultivating talents with morality,it pointed out that the development of core literacy of students mainly refers to the necessary character and key ability that students should possess and can meet the needs of lifelong development and social development.To develop and cultivate the core quality of chemistry is the highest goal of chemistry teaching and the teaching pursuit under the new curriculum reform.What kind of teaching methods can effectively develop students' chemical core literacy in teaching has become an urgent problem to be solved.Facing the new challenge,we should change the traditional teaching concept,put the chemical content in the situation,let the learning and the situation connect with each other,experience,explore and discover in the situation,so as to obtain the necessary ability of meaning construction.The situation teaching undoubtedly becomes one of the important ways to develop the chemistry core element of senior high school students.Based on the perspective of situational teaching,this paper studies how to cultivate high school students' chemical core literacy.First of all,through literature review and the application of relevant educational theories,this paper interprets the core literacy of situational teaching and chemistry,and discusses the practical significance of using situational teaching to cultivate and improve students' core literacy in classroom teaching.Secondly,through the methods of questionnaire,classroom observation and teacher interview,we can understand the current situation of cultivating high school students' chemistry core literacy and situational teaching in chemistry teaching,find out the existing problems and reflect on them to avoid similar problems in teaching practice.Finally,the teaching contents of "redox reaction","important compound of aluminum" and "silicon,the leading role of inorganic non-metallic materials" in the compulsory one of senior high school chemistry of human education edition are selected for scenario design and teaching in parallel classes.After the teaching,test questions are distributed and recycled for comparative analysis and arrangement.Through comparative analysis,we can know that knowledge is integrated into the context for teaching and filling,students can analyze macro phenomena from micro perspective,correctly understand chemical changes in the process of material transformation,learn to reason and establish relevant models,conduct scientific research in experiments,realize the value of learning chemistry and solve practical problems,which is conducive to students' formation of chemical discipline ideas,mastering chemical methods and effectively improving teaching quality,in order to achieve the goal of developing high school students' chemical core literacy in classroom teaching.At the end of the fourth chapter,the teaching suggestions are given.This paper makes a practical research on the combination of situational teaching and chemical core literacy,and conducts situational teaching in accordance with the specific teaching content of senior high school chemistry in the actual classroom,so as to provide reference for the majority of teachers to promote the development of students' chemical core literacy from the perspective of situational teaching.
