Design And Practice Of High School Chemistry Concept Teaching Based On Core Literacy

The introduction of core literacy points out the development direction of the new curriculum reform.How to cultivate students' core literacy in chemistry teaching has become an important issue.The concept of chemistry is an important part of chemistry teaching.The development of core literacy is inseparable from conceptual teaching.Therefore,how to implement core literacy in concept teaching is of great significance.Based on the cultivation of students' core literacy,combined with the existing research on chemical concept teaching and core literacy,as well as the investigation and analysis of the current situation of high school chemistry concept teaching,this paper proposes a chemical concept teaching design model under the guidance of core literacy.The model conducts practical research,and the practice shows that the model can promote the learning of chemical concepts and promote the core literacy of students.This article is divided into six parts,the specific content is as follows:The first part: Introduction.This paper introduces the background,research purpose,significance and main content of this research,and analyzes the status quo of core literacy and chemical concept teaching and "hydrolysis of salt" from abroad and domestic.The second part: theoretical basis and concept definition.It mainly expounds constructivist theory,humanistic theory and meaningful learning theory,and defines the core literacy,chemical core literacy,chemical concept and teaching design.The third part: the investigation and analysis of the current situation of high school chemistry concept learning and teaching.The subjects selected in this study were 200 students in the second year of a high school in Nanchang City,Jiangxi Province,and five high school chemistry teachers.A questionnaire survey was conducted on the current learning situation and teaching situation of high school chemistry concepts.At the same time,interviews were conducted with teachers,mainly focusing on the current problems of students in the study of chemical concepts,and analyzing the causes.The fourth part: the construction of the chemical concept teaching design model based on core literacy.It mainly analyzes the teaching links of the instructional design model.The fifth part: teaching design and practice.According to the proposed model,the teaching design and teaching practice of the concept of “hydrolysis of salt” in the chemical elective 4 of the PEP.The sixth part: research conclusion and prospect.It mainly summarizes the research content of this paper,and reflects on the shortcomings of this research,and makes a prospect for future research.
