Research On Teaching Strategies Of High School Chemical Element Compounds Based On Core Literacy

In 2018,the "General High School Chemistry Curriculum Standards(2017Edition)",which has attracted much attention,was officially released,using a lot of space to introduce the core literacy of the subject from five dimensions.This points out the direction for the education and teaching of frontline teachers,requiring teachers to organically combine the characteristics of the chemistry subject with the core literacy while teaching,so as to cultivate students' good subject character.Although there are many researches on the core literacy of disciplines,there are many people who don't know how to penetrate.Therefore,in order to better cultivate students' core literacy,research on teaching design based on core literacy is also of great significance.Elemental compounds occupy a very important proportion in the high school chemistry knowledge section,and today's high school exam questions are no longer simple knowledge reproduction,and more inclined to the application of ability.Both teachers and students expressed headaches when they encountered knowledge of elemental compounds.Although it is not difficult,the knowledge points are too scattered and messy,and they are often memorized and forgotten,which leads to low learning efficiency.Even if they are memorized,they can't do the corresponding exercises.This article is mainly based on the problems encountered in frontline teaching,combined with the core literacy of chemistry,to study how to infiltrate the core literacy in the teaching of elemental compounds,improve teaching efficiency,and cultivate students' comprehensive abilities.This article will conduct research on the teaching strategies of high school chemical element compounds based on core literacy through six chapters.The first chapter is the introduction,from the aspects of research background,research purpose and significance,research content and research methods,and research status,it briefly expounds the practical significance and methods used in the research of this topic.This article mainly uses literature research method,investigation method,action research,case study and other methods to complete this research.It is hoped that the research on element compound teaching strategy can provide teachers with reference for core literacy teaching.The second chapter is related concepts and theoretical foundations.This article mainly searches for relevant literature and analyzes the current teaching situation to find useful theoretical foundations for research,including "constructivism" theory,"Osubel meaningful learning theory",and "STSE concept" ","Ebbinghaus Forgetting Curve".The third chapter is a survey of the current situation of teaching and learning about chemical element compounds in high schools.It mainly analyzes the current situation of teaching and learning of teachers and students of the author's school through questionnaire surveys.In order to have a deeper understanding of the current situation of teaching and learning,actions are also taken.The research method goes deep into the real classroom and feels the state of teachers and students.The fourth chapter analyzes the element compound teaching strategy based on the core literacy of chemistry,based on the principle of curriculum standards and student-based thinking,and considers the direction of designing teaching strategies,including infiltration of the core literacy of chemistry,a variety of ways to stimulate students' interest in learning,A variety of methods cultivate students' ability to independently construct knowledge networks,learn to let go,problem design should be open,and cultivate students' sense of cooperation and inquiry.Chapter 5 is a teaching case based on the core literacy of the subject.A teaching case is selected from metals and their compounds and non-metals and their compounds to show and analyze how the author penetrates the core chemistry literacy in actual teaching.The sixth chapter conclusions and prospects,using different teaching methods to teach different classes at the same level,and finally confirmed through the results that the teaching strategy based on the core literacy of the subject is effective and can reflect the value of the chemistry subject in chemistry teaching.Finally,it also summarized the shortcomings in this research,and called on more researchers to participate in the ranks of teaching research based on the core literacy of the subject.
