Research On Teaching Design Of High School New Textbook Column Based On Chemistry Core Literacy

The 2017 edition of the curriculum standards advocates "literacy based" chemistry teaching in teaching,emphasizing the transition from "knowledge" to "literacy".The core literacy of chemistry is implied in the textbook,and the column is the further development and deepening of the basic knowledge of the textbook.The column setting provides relevant materials,data and methods for students to solve problems,and in-depth analysis of the columns in the textbook plays an important role in the construction of knowledge and the development of the core literacy of chemistry.This thesis takes the 2019 People's Education Edition "General High School Textbook Chemistry Compulsory" as the research object,analyzes the columns in the two textbooks,and summarizes the characteristics of the columns and the teaching value of each column based on the classification and statistics of the knowledge points of each column.The results show that teachers and students have a high degree of recognition of the columns in the new textbook,but there are still some problems in the specific implementation of the teaching process.Based on the consideration of the current survey issues,improving the difficulties in the implementation of the columns and cultivating students' core literacy of chemistry,according to the teaching status and teaching value of different columns,different teaching strategies are proposed for different types of columns.Active columns guide students to understand knowledge and improve skills in inquiry activities;expandable columns extract effective information in reading;method columns guide students to master scientific methods and construct models.Finally,it integrates various columns into the teaching process to cultivate students' core literacy in chemistry,and conducts specific teaching case design.Two teaching cases with different columns as contextual clues and three teaching cases with one column content as the main design teaching activities are selected.Practice and verify the feasibility and operability of integrating column content in teaching to cultivate students' core literacy in chemistry through the evaluation of teaching effects.Through the above research,this article shows that there are richly designed columns in the textbook,and each column has a different function.Incorporating column content into teaching can give full play to the teaching function of the column,make the teaching effect more ideal,and effectively improve the core literacy of students in chemistry.
