Application Research Of Mind Mapping In The Exploratory Experimental Teaching Of Chemistry In Junior Middle School

The new curriculum reform proposes to emphasize the main position of students in teaching and the leading role of teachers.In the teaching process,teachers must not only pay attention to the teaching of knowledge,promote the study of students,but also pay attention to the cultivation of students' innovative ability.The chemistry inquiry experiment teaching in chemistry has received more and more attention,however it is often difficult to achieve the expected teaching effect due to the influence of curriculum arrangement and teaching content.In the process of drawing mind maps,the invisible thinking in the human brain can be expressed by the curves,graphic icons and colorful elements in a graphical way,which can make the abstract knowledge concepts much more visual.The use of mind mapping tools in junior high school chemistry inquiry experiment teaching not only can show the process of scientific inquiry by teachers and students,but also form a knowledge network map through the connection of knowledge concepts to help students better master the process and method chemical exploration.This research combed the application of mind maps to the field of education and teaching through literature research,and constructed the theoretical basis of the application of mind maps to junior high school chemistry inquiry experiment teaching.Integration the advantages of mind maps and the characteristics of chemistry inquiry experiment teaching,this research discussed the appropriateness of the application of mind map to junior high school chemistry inquiry experiment teaching.On the basis of comprehensive analysis of the contents of the junior high school textbooks and understanding of the students' learning situation,the teaching cases were designed by selecting the "composition of water","conservation of mass" and "research on the preparation of carbon dioxide" in the junior high school textbook.After the teaching experiment,the author collected relevant data,and evaluated the effect of case implementation through statistical analysis,interview analysis and physical analysis.The research has the following conclusions: First,the use of mind mapping tools in chemistry inquiry experiment teaching can effectively improve students' chemistry exploration experiment academic achievements.Using mind maps helps students masterchemistry experiment knowledge,can effectively promote brain memory,transform short-term memory into long-term memory,and strengthen the effect of students' learning chemistry experiments.Second,the use of mind maps promotes the cultivation of students' classification concepts.The use of mind maps to classify chemical knowledge,to integrate and reorganize scattered chemical theory knowledge,can improve students' ability to summarize and generalize.At the same time,when searching for information,it is convenient for students to extract the information needed to achieve efficient memory.Third,mind maps can effectively improve students' interest in learning chemistry inquiry experiments and help students form the basic ideas and methods for learning chemistry experiments.
