The Application Of Mind Maps In The Teaching Of “first Knowledge Of Acid And Alkali” In Junior High School Chemistry

Junior high school chemistry involved with many contents,such as Chemical concept,chemical experiment,the principle of chemical computation,etc.The students understand it in the study,but then the understanding becomes unclear,even forgotten.Dealing with heavy learning task,scattered multifarious chemical knowledge,many students are difficult to sort of chemical knowledge clues and their inner relationship.It is poor for them to develop the migration ability and general conclusion ability.Acid and base salt in junior high school of learning,for it is the difficulty of junior high school student study are emphasized,more and more scattered knowledge is not easy to memory,use mind map as a teaching strategy use acid base salt to the teaching,can put the messy information composition information piece,understand the connection,it is easy to remember.The study is mainly focus on how to use the mind map in teaching the chemical subject for junior high students.In the paper,mind map is used as one kind of teaching model applied in the new lesson and the review lessons.After a period of time in the experiment teaching,the experimental class and the contrapositive class was tested by exam.By combining the state of students using the mind map,Mind map is effective to improve the scores of the students.Ultimately the results show that the mind map helps to improve chemical study effect,also suitable to improve the students thinking of expanding and the ability of learning.Therefore,this study could prove that the mind map is a suitable tool for junior high school students to learn chemistry.
