Research On The Application Of Anchored Teaching Method Based On Developing Of Core Literacy In High School Chemistry Teaching

The "General High School Chemistry Curriculum Standard(2017 Edition)" defines the task of cultivating students’ core chemistry literacy in teaching,and requires education to be devoted to cultivating students’ core literacy,and the classroom should shift from a "knowledge center" to a"competence center" and pay attention to student abilities Cultivation.The "nchored teaching method"based on constructivist theory can create real teaching situations,which can make students question and stimulate their learning motivation.Students can solve problems through independent learning and cooperative learning,thereby constructing knowledge and cultivating abilities.This article used anchored teaching method to design teaching cases and develop students’ core literacy in chemistry.The research work consists of six parts:Part 1:Research overview.By reviewing and analyzing the research status of anchored teaching methods and core literacy at home and abroad to clarify the research background,it is found that the anchored teaching method has outstanding advantages in cultivating the core literacy of students,but there are few related researches.Therefore,this article intends to choose" "Metals and their compounds"chapter content,explore the application of anchored teaching methods to cultivate students’ core literacy.Part 2:Concept definition and theoretical basis.The concept and theoretical basis of anchoring teaching method and chemistry core literacy are defined,the content of the chapter "metals and their compounds" is analyzed,and the relevance between teaching theory and research content is explained.Part 3:Current situation analysis and method construction.To understand the current frontline teachers’ cultivation of students’core literacy through investigations,to understand teachers’ and students’awareness of anchored teaching methods,and to analyze the feasibility;by analyzing the principles,links,and connotations of the anchored teaching method,construct localized anchored teaching based on the process model of chemistry teaching design law.Part 4:Case design.Taking the three class hours of "Properties and Applications of Metal Sodium","Important Compounds of Sodium" and "Important Aluminum Compounds" in the "Metals and Compounds" chapter of the compulsory one of the People’s Education Edition as practical examples,explore the application of anchored teaching methods to train students Core literacy.Under the guidance of constructivism theory,recent develo-pment area theory,and situational cognition theory,this article conducts teaching through five links:creating situation—determining problems—autonomous and cooperative learning—solving problems—effect evaluation.Taking "The Nature and Application of Metal Sodium" as an example,the "Pearl River Explosion" event was selected as the context in the context of creating the context,to stimulate students’ desire to explore and interest in learning,and to cultivate a sense of social responsibility;In the course of autonomous and cooperative learning,students are guided to learn the chemical properties and uses of sodium in groups such as group cooperation,experimental exploration,and autonomous learning;Flexible teaching methods help to cultivate students’ chemical thinking;Various evaluation methods are used in the effect evaluation link to promote the overall development of students.Part 5:Practical research.Use teaching tests,questionnaire surveys and interviews to analyze the effect of the anchored teaching method.The results of the test papers after practice:the average scores of the experimental class and the control class were 55.64 and 50.45,respectively,and the significance levels were 0.628 and 0.026 respectively.There was a big difference in the results;the correct answer rate of the experimental class was significantly better than that of the control class;questionnaire survey and the results of teacher interviews show that students have good changes in learning interest,learning style,and subject ability after practice.Part 6:Conclusion.The anchored teaching method case design and application based on the development of core literacy can effectively promote students’ learning effects to a certain extent,mobilize students’ learning interest and enthusiasm,cultivate students’ experimental exploration,analysis,problemsolving abilities,and can also improve students’ independent learning and teamwork ability.In general,this research has a certain positive effect on the cultivation of students’ core literacy,and can provide some references for frontline teachers.
