The Research On The Teaching Of Chemistry Frontier Knowledge Based On Core Literacy

Chemistry is one of the important basic disciplines,the rapid development in recent years has played a more and more important role in human life and social development.Therefore,the teaching of chemistry in middle school can not only be limited to the teaching of basic knowledge and skills of chemistry,but also guide students to understand the research and application of chemistry in different fields and the latest development trend,so as to help students understand the irreplaceable important role of chemistry in human life,so that the cultivation of chemical talents can keep pace with the development of the times.At present,most front-line teachers and high school students mainly acquire and learn the frontier knowledge of chemistry from the teaching materials,but because the teaching materials can not be updated in time,the frontier knowledge that students know has a certain lag.Based on the background of developing students' core literacy in chemistry subject and constructivist learning theory,proximal development area theory and so on,using interview method,questionnaire method and so on,we can intuitively understand the information of teachers and students' interest in chemical frontier knowledge,cognitive attitude and the way to acquire frontier knowledge.Compare and analyze the similarities and differences between Chinese and American chemistry teaching materials in setting up the frontier knowledge of chemistry,acquire the latest frontier knowledge of chemistry through various ways,and design the corresponding teaching cases in combination with the teaching content.According to the results of interviews and surveys,most teachers and students can recognize the importance and necessity of understanding and learning the frontier knowledge of chemistry,but there are few ways for teachers and students to obtain the frontier knowledge and the teaching methods to integrate the frontier knowledge of chemistry into the teaching.Read and combine the requirements of chemistry frontier knowledge teaching in general high school chemistry curriculum standard(2017 edition),compare and analyze the characteristics between Chinese and American chemistry teaching materials in the content setting,presentation mode and column of chemistry frontier knowledge.According to the research results,put forward three teaching strategies of chemistry frontier knowledge teaching based on the background of chemistry core literacy: making full use of teaching materials and other ways to obtain chemistry frontier knowledge;pay attention to the interest of introducing the frontier knowledge of chemistry;creating teaching situations and guiding students to take the initiative in learning.Rational use of teaching strategies,four teaching fragments and two complete teaching cases are designed by selecting multiple chemistry frontier knowledge combined with specific teaching content.The exploration and research of this paper aims to provide some useful reference for the vast number of front-line teachers in the aspects of material acquisition,teaching methods and strategies.
