| Chemistry is a subject based on experiment.The experimental part is important in the content of junior middle school chemistry teaching.And it is complicated to review.Mind mapping can make the complex knowledge points more intuitive and networked in the brain.It also helps us form a whole understanding of the content.Mind mapping links each point of knowledge with the entire content,helps us grasp the overall content from the macro and master the specific knowledge from the micro.Therefore,I design the teaching model of the junior middle school chemistry experiment review course based on the mind mapping,and carry out the research in practice.The main research contents are as follows:First,I analyze the relevant literatures,determine the background,purpose and significance of the study,and point out the research content and methods.In addition,I introduce the mind map briefly and summarize its related researches in middle school chemistry.Then,in order to make junior middle school chemistry experiment review more targeted and efficient,I summarize the contents of the experiments and analyze the experimental questions of chemistry in the2014-2016 experiments in Shenyang from two aspects: the proportion of the test questions and the number of knowledge points involved.I also discuss the importance of chemical experiments and grasp the high-frequency chapter of the experimental questions in the test as a selection of teaching cases in this article.Finally,I combine the junior high school chemistry experiment review with mind mapping,design the teaching model of junior middle school chemistry experiment review class based on mind mapping,andapply it to the actual teaching.In order to examine its application effect,I select two parallel classes to study.I use the mind map to carry out the experiment review in the experimental class,and use traditional method to review in the control class.After a period of time,I analyse the student performance quantitatively.I also study the change of students' subjectivity according to the interview method to verify the effect of mind mapping in the review of junior high school chemistry experiment.Research shows that chemical experiment contents in the teaching of junior high school occupy an important position and account for a large proportion in the test chemistry.It can improve the students' achievement by applying the mind mapping to the junior middle school chemistry experiment review,and help students form efficient knowledge network.What is more,it helps to improve their innovative thinking and learning interest. |
