Cultivating Middle School Students' Chemical System Thinking Based On Mind Map

Based on the three comprehensive requirements of the new curriculum standard,the new college entrance examination and the development of modern technology,it is emphasized that students should have systematic thinking and the ability to solve complex problems with the overall view.According to the analysis of the characteristics of chemistry subject knowledge,the author thinks that chemistry teaching course is a subject suitable for cultivating students' systematic thinking.According to the actual teaching situation of high school chemistry,combined with the application prospect and feasibility study of mind map in subject teaching,this paper puts forward the argument of cultivating middle school students' chemical systematic thinking based on mind map.System thinking thinks that all things in the world can become a system.Thinking things as a whole from the perspective of the whole is conducive to grasp the relationship between the whole and parts,parts and parts,system and external environment.This paper mainly studies the cultivation of students' chemical system thinking ability based on mind map.By using system thinking,the content of chemical knowledge is regarded as a system,and mind map is used as a teaching method to train students' system thinking ability.Chemistry teaching,mind map and system thinking are organically combined to cultivate students' chemical system thinking As a teaching method,dimensional map is used to design chemistry teaching.This paper is divided into five parts.The first part: introduction.The introduction introduces the current situation of the research at home and abroad from the needs of the reform of college entrance examination,the current situation and characteristics of chemistry teaching,as well as the author's own learning experience and the needs of students' own development.It also expounds the purpose,significance,ideas and methods of the research.The second part:theoretical basis and related concepts.This paper introduces the concepts related to system,system thinking,thinking,mind map,and the theories involved in this practical research,such as system theory,brain science theory,double coding theory,etc.It also introduces the research object,content,research methods used in the research process,research ideas,purpose and the significance of this research.The third part: the investigation and analysis of the current situation of high school chemistry system thinking teaching based on mind map.It mainly carries out questionnaire survey and performance analysis on students,interviews with teachers,and analyzes the survey results.The fourth part: teaching practice based on mind map.This paper lists several teaching cases in which the author uses mind map as a teaching method,and makes a post test and post test analysis of the teaching effect.Post test analysis includes student questionnaire,student interview and analysis of students' test scores.The fifth part: conclusion and prospect.Summarizing the conclusions of this study,the study shows that mind map has certain advantages in cultivating students' chemical system thinking.The organic combination of mind map and chemical teaching has achieved good teaching effect.Hope to provide some help for front-line chemistry teachers to cultivate students' chemical system thinking.
