Research On The Influence Of Senior High School Students' Life Experience On The Formation Of Concepts

Living in the big family of society,students not only get knowledge through school education,but also through life experience outside school.So it is the acquisition of chemistry related concepts.When these concepts of self-knowledge conflict with scientific concepts,they may hinder students' learning.The concept of acid plays a very important role in the middle school chemistry curriculum and is closely related to our life.Therefore,this study aims to take the concept of acid as an example to analyze the impact of high school students' life experience on the concept formation.This study first analyzes the sequence and internal logic of acid concept knowledge in chemistry curriculum standards and chemistry textbooks,and uses the relevant research results of acid concept at home and abroad for reference to determine three content dimensions of acid concept knowledge: "common acid","acid concept" and "acid".According to the three content dimensions of acid concept knowledge,combined with students' life experience,an interview questionnaire about the influence of life experience on acid concept formation was developed.Then 12 senior high school students from two provincial key middle schools in Jining are selected as the research objects,and semi-structured interviews are conducted to clarify the connotation and source of life experience related to acid concept knowledge according to the students' answers.Finally,the qualitative research method is used to analyze the interview data and explore the influence of high school students' life experience on the formation of acid concept.The results show that:(1)the life experience which influences the formation of the concept of acid in high school students is rich;(2)different life experience will have different influence on the scientific concept of acid in high school students;(3)different life experience will influence the different conception in the formation of the concept of acid in high school students.The main innovations of this study are as follows:(1)according to the connotation of the concept of acid and the students' life experience,this study developed an interview questionnaire on the influence of life experience on the formation of acid concept,which provides a reference and new testing tool for the related research of the concept in the future;(2)using semi-structured interview to collect data and qualitative research method set This paper analyzes the influence of high school students' life experience on the formation of acid concept,which provides an important reference for concept teaching.
