Exploration And Practice Of Chemistry Variant Teaching In Senior Middle School

In the paper, variation teaching not only belongs to teaching behavior but alsomeans teaching strategy, and it also refers to a teaching form．It refers to presentingknowledge in our teaching process from different aspects，such as changing the wayof presenting knowledge, adding interference during the teaching process and so on,which aims to have students master the essence of knowledge during the explorationand the research of study. In this way, they can be unchangeable on the changeablebasis and they also can deal with the changing events based on the unchangeableprinciple．In this way, we can reduce the burden of students, motivate the learninginitiative of students and lay the foundation for their future learning．The aim of the study is to analyze the functions of variation of chemistryteaching in the current senior high school by using the practical examples of teachingand learning according to the current situation of chemistry teaching and variationteaching. The paper studies the features of variation during the study of middleschool students and the aspects of the variation competence by follow upinvestigation,interview and so on, which offers help to the efficient variation teachingand to the analysis of chemistry knowledge’s variation in university-entrance exam.What’s more, it helps teachers to master variation teaching based on the practicedsituation efficiently.The paper is to try to find a way to reduce students’ learning burden, increase theefficiency of teaching and learning and guide the instructive variation teaching inchemistry teaching of high school by analyzing the theories of variation teaching,thesituation of students’variation teaching and connecting the teaching practice withteaching thoughts to develop a series of activities．...
