Research On The Teaching Of Concept Transformation Under The Background Of Core Literacy Of Chemistry

Chemical concept is the foundation and beginning of chemistry learning.It is also an indispensable part of the advanced learning process.Chemical concept is the language of learning chemistry.If we want to learn chemistry well,we should learn more about the concept.Before learning the chemical concepts of science,students have got a certain understanding of chemical concepts in their lives and studies.We call them preconcepts.The former concept is partly a scientific concept based on theory,but there is also a part of the conceptual concept that is different from that of the scientific concept,which is the concept of misconceptions.Neglecting the formation of misconceptions is not conducive to the learning of chemical knowledge,and it is also easy to cause accidents in real life.Under the background of the chemistry key competency,the quality of chemistry should help students to form the necessary character and key ability.Therefore,it will promote the transformation of the students’ mental literacy,complete the conceptual change,and construct the scientific concept of the students,and become one of the important topics that need to be studied now.Based on the chemistry key competency,this study helps students transform their misconceptions into scientific concepts and cultivate their core qualities.To help students to build a correct view of learning and society and to cultivate the core values of the students’ Socialism.This article is divided into four parts:First of all literature review,summary of research reviews at home and abroad of key competency and conceptual change,and summarize the direction and trend of development.Second definition of core concept,The definition of core literacy is mainly based on the analysis and summary of the description by various countries or organizations,and the definition of conceptual change is related to the related theories.then Research methods and theoretical basis,Based on Piaget’s cognitive development theory,Ausubel’s cognitive assimilation theory and constructivist conclusion,this research is designed through literature research,questionnaire survey and interview.Finally Conceptual change teaching design and implementation under the background of key competency in Chemistry.Taking the people’s education press to choose four primary batteries as an example,the practice and research of a high school in Zhumadian are carried out.After interpreting and analyzing the teaching materials,we set up the pre test volume accordingto the requirements of curriculum standard and key competency for students’ training.Combined with the interview results of teachers and students,we got the concept of students’ preconceptions and misconceptions.On this basis,we carry out instructional design and implementation,use analogies and other strategies to trigger students’ cognitive conflict,contrast the pre concept and scientific concept in students’ minds,and lead the conflict between misconceptions and scientific concepts in the former concept.The scientific concept of the original battery is imparted to students by using the literacy of the chemistry key competency.It helps students to build scientific concepts,realize conceptual change,teach students the correct way of learning,and cultivate their correct outlook on learning,life and values.The study shows that before students learn new concepts,the concept of confusion in the mind will impede the enthusiasm of the students and influence the learning of new concepts.The concept change teaching under the background of chemistry key competency can help students learn chemistry knowledge effectively,students build scientific concepts and cultivate students’ innovative consciousness and practical ability.
