Research On The Teaching Effectiveness Of Chemistry Concept In Junior High Schools

In the perspective of chemistry, the formation of chemical knowledge system depends on the correct construction of chemistry concepts. By doing a research into teaching chemistry concepts, teachers can improve the teaching effects, so that the teaching aims can be achieved more effectively. And the improvement of effective teaching will enable students to form the reasonable cognitive structure that they will understand chemical substances and their changes, rather than stay in the low-level perceptual stage. Further more, it helps students build a systematic network of chemical knowledge. More importantly, through the training of the logical thinking ability, students will acquire how to learn chemistry.This topic is on the background of the domestic and foreign researches into the chemistry teaching in junior middle schools. Combining the teaching experiences, the author did some researches into the chemistry teaching strategies and effective measures to enrich and improve chemistry concepts: (1) Make a survey about students'situation and different methods in chemistry concept learning, as well as teachers'teaching activities which may influence teaching results, so that the author can master first-hand information which will make the research more targeted;(2)Observe and analyze how to teach chemistry concepts effectively, find out the problems and causes, and adopt concrete measures;(3)Use the new teaching theories to analyses chemistry concepts teaching, sum up experience, put forward new requirements, and provide practical theories and methods in order to improve chemistry teachers' teaching in junior high schools. In the research, the author transformed the traditional teaching models, and new methods for chemistry concept teaching, so that students could improve their learning efficiency, and the author could enhance her teaching and upgrade research capabilities as well.
