High School Chemistry Teaching Design Based On Core Literacy

Faced with the continuous updating of cultural knowledge and the globalization of economy and science and technology,“core literacy” has become the education topic that meets the needs of social development and the development trend of education in the 21 st century.In terms of the basic education,the 18 th National Congress of the Communist Party of China put forward the fundamental task of the education of "moral education".To achieve this goal,it needs to be implemented to develop students' core literacy in the classroom.Chemical situated teaching has far-reaching significance for effectively improving the quality of chemistry courses teaching,students' learning efficiency,cultivating students' interest in learning,and developing students' core literacy.The knowledge of the "Chemical Reaction Principles" in high school chemistry is the core part of the chemical subject knowledge system.It shows the basic orderliness of chemical reactions and their practical application in production and life.It is the supplement and deepening of elemental compounds.This part covers the three major difficulties of high school chemistry(solution,equilibrium,electrochemistry).This paper summarizes the connotation of chemical core literacy through literature research,and carefully analyzes the knowledge content of "Chemical Reaction Principles".Under the guidance of constructivism and situational cognition theory,the knowledge content of the principle of chemical reaction has abstract and broad characteristics,and the practice research method is used to carry out teaching.Based on the basic requirements of cultivating people in the chemistry of core literacy,three situational teaching cases were designed,and teaching practice was studied in the G high school senior two(10)class.After practice,a questionnaire survey was conducted on the effectiveness of this teaching model.By analyzing the data,we conclude the conclusion.In the teaching of chemical reaction principle knowledge,the situational teaching mode can mobilize the initiative and enthusiasm of students' learning,help students to acquire general knowledge through cognitive activities,and migrate applications in other situations;improve students' ability to complex challenging problems in solving social life.It is able to cultivate students' chemical literacy and develop their core literacy.
