Practical Research On Using IHV Teaching Mode To Improve Middle School Students' Interest In Chemistry Learning

Chemistry interest means how students are interested in learning chemistry.Recently,studies have shown that students interest in learning chemistry can be divided into four molds,such as perception,operation,exploration and create interest according to their different levels.There is close connection between these interests and many facts,for example,teaching methods,experiment,practice application.IHV(internative historical vignettes)teaching model is a chemical history teaching method,it will be related to the teaching theme of the chemical history adapted for a series of lively,well-designed,interesting short essays used in chemical teaching.The IHV teaching model can improve interest for students to learn chemistry by its interesting,cooperative,knowledgeable,practical and innovative and chemical interest,so IHV teaching model can not be ignored in the procese of chemistry learning.At present,the research on the influence of IHV teaching mode on students 'interest in chemistry has rarely been reported and the research is not deep.Therefore,the influence degree of students' interest in chemistry learning in IHV teaching mode will be an extremely important subject,And how to design a course for teachers.In this paper,we first design a questionnaire to stimulate interest inlearning to conduct a random sample survey of freshmen with high school chemistry learning experiences in three different levels of colleges and universities in Changsha to obtain the influencing factors of chemistry interest.Then,in Shaoyang County,Shiqi middle school randomly selected experimental classes and control classes,and in the experimental class IHV teaching practice for a semester,the final design and adaptation of a "Chemical Learning Interest Questionnaire" were the experimental class and control Class students to conduct a comprehensive investigation.Through the collection,collation,statistics,analysis of data finally get the following conclusions:1.The use of IHV teaching model to teach the history of chemistry can effectively improve the interest of students in chemistry learning.In this study,the doubts about the origin of chemical knowledge can be solved by the teaching of chemical history.At the same time students lack of interest in the chemistry class can be through the IHV teaching model in the interactive interaction to make up.2.IHV teaching model can significantly improve the chemical interest in chemical interest and interest in chemical inquiry.The IHV teaching method creates a lively classroom situation,and also allows students to participate in the creation of the whole situation,thus cultivating the interest and ability of secondary school students to actively explore the knowledge of chemistry.3.IHV teaching model can strengthen the participation of students in chemistry class.
