Research On Teaching Practice Of High School Chemistry Concept Understanding Based On Real Situation

The new curriculum standard of high school chemistry points out that teachers should create real situation to teach.Many high school students shy away from the abstract subject of chemistry.Therefore,this paper discusses how to promote students’ understanding of abstract chemical concepts based on real situations.The research work of this paper is mainly carried out from three aspects:(1)Theoretical research: By referring to relevant literature,we can understand the research status of the real situation and chemical concepts,clarify the research significance and content of this paper,and elaborate relevant educational theories.(2)Investigation and research part: Questionnaire survey method was adopted to issue questionnaires to students to understand students’ understanding of the real situation in chemistry classroom teaching and the development status of concept understanding teaching.Teachers were interviewed to understand teachers’ opinions on creating real situation to improve students’ understanding of chemistry concept.Finally,corresponding conclusions were drawn through analysis of survey results.(3)Teaching theory analysis and teaching practice: According to the survey results,the basic elements,principles and approaches to create real situations and teaching strategies to improve students’ concept understanding level are proposed,which are taken as the theoretical basis to carry out teaching practice research.The teaching practice objects are all the students in the two classes.The content of the teaching practice is REDOX reaction in the first volume of compulsory high school Chemistry for Human Education edition(2019 edition)and the two concepts of galvanic battery in the second volume of compulsory high school Chemistry for human education edition(2019 edition).The teaching practice method is to carry out concept understanding teaching in real situations in the experimental class,and adopt the general teaching mode in the control class.The test method of teaching practice effect is to conduct pen and paper test for students in two classes,and compare and analyze the achievement and concept understanding level of the pre and post test.Finally,the summary reflection.The main conclusions are as follows: creating real situation can mobilize students’ past experience and learning initiative;Creating a real situation can promote students’ understanding of chemical concepts.Creating real situation can improve students’ concept understanding level.
