With the improvement of social information degree,the contact of life science and technology more and more close,the progress of science and technology is often directly determines the country's future development prospects,constantly improve the level of citizens' scientific literacy is the basic needs of social development and people's life,various countries have started the scientific literacy training plan.Primary school students are the future of our country,and their scientific literacy directly affects and determines the overall level of our citizens' scientific literacy now and in the future.If a country wants to lead the world in key science and technology,international competitiveness and various fields,it must pay attention to the cultivation of students' scientific literacy in the basic education stage.The cultivation of scientific literacy is of continuity,integrity and comprehensiveness.The improvement of students' scientific literacy in primary school is not only conducive to the connection of knowledge contents,skills and emotions among students,but also conducive to the integration of knowledge exchange,understanding and development among subjects.Primary school has started to learn science courses since the first grade,but the comprehensive cultivation of scientific literacy is not only the responsibility of a discipline or several science disciplines,the Chinese curriculum should also take up the cultivation of students' scientific literacy.In Chinese teaching,especially the teaching of expository texts in primary schools contains abundant teaching resources to cultivate scientific literacy.Through the comprehensive and systematic in-depth learning of listening,speaking,reading and writing,students can fully open their scientific vision,read extensively,accumulate knowledge and experience,and comprehensively improve their logical reasoning ability,inductive and deductive ability,imagination and creation ability.It is also conducive to students' comprehensive cultivation of the scientific spirit of seeking truth,questioning and criticizing,competition and cooperation.Exposition teaching content is an important part of the elementary school language teaching material,has the language features of accuracy,rigor,rich in content and knowledge science,times,and strong practicability.However,according to the survey,interview and data analysis,it is found that primary school Chinese teachers generally do not pay attention to expository teaching,and there are some problems such as simple text interpretation,single teaching process,unclear learning objectives and so on,which do not fully explore its due teaching value.Especially in the aspect of reading material recommendation and guidance,students'interest in reading is not sufficiently aroused;the problem design in class lacks logic and pays little attention to the cultivation of students'scientific thinking.The exploration of humanistic spirit is not enough,and the guidance of students'scientific spirit is not enough.In primary school expository teaching,teachers generally pay little attention to the cultivation of students'scientific literacy,so the cultivation of students'scientific literacy is determined by the inherent requirements of the teaching content,and it should play an important role in this respect.This paper is about the primary school expository teaching in the improvement of scientific literacy training of research and exploration,the content is mainly divided into the introduction and four parts,analyzes the current primary school expository teaching in the main problems,and combined with the teaching theory and practice put forward specific teaching strategies and attention to the problem.This paper is about the primary school expository teaching in the improvement of scientific literacy training of research and exploration,the content is mainly divided into the
