Under New Curriculum Background At The Beginning Of High School Chemistry Concept Teaching Engagement Research

New secondary school chemistry curriculum reform, the chemical knowledge to take "three-step" design, in various stages of secondary school chemistry, the concept of the contents of both the existence of chemical, we need to be aware of; new curriculum standards in the chemical, many chemical definition of the concept of major changes have taken place, for some chemicals than the requirements of the concept has increased, the concept of a number of chemical requirements slightly lower than in the past and increase the number of new chemical concepts. Chemical concept of learning has always been an important foundation of chemical knowledge, which is more abstract and chemical study of the major and difficult; chemical concept of other chemical knowledge has an important role of commander in chief, and its important status. Survey found that the implementation of the new high school courses, there are a considerable number of students entering high school, the chemical results are a lot of drop, the students that "the concept of high school chemistry more difficult to learn, difficult exercise." And thus lost confidence in the chemical study . And high school chemistry teacher is also difficult to teach new students feel that "the concept of some chemicals has been repeatedly talked about quite a few times, there are students that do not know, is very vague." Of course, the cause is multi-faceted, but we think its lies the root of the main middle and high school chemistry teaching, especially the concept of teaching chemistry to deal with the convergence of the original. Therefore, it is necessary for teaching the concept of convergence of the chemical to conduct a comprehensive analysis of the problem and exploring.Modern teaching theory stresses individual learning activities in teaching subjective, dynamic, emphasizing the openness of the teaching, and developmental differences. Chemical concept of convergence of the classroom teaching the new curriculum should reflect the basic philosophy, students pay more attention to teaching activities in the main body of the status and role in enhancing the effectiveness of teaching. To constructivism, "to the organizers of strategy as the chemical basis of the concept of teaching the theory, the concept of great importance to the beginning of high school chemistry teaching convergence; control the chemical content of the concept of teaching the depth, breadth, handle the teaching of the chemical concept of compulsory modules and elective modules of the relationship between ; attention to overcome the chemical concept of abstract, difficult to understand the difficulties caused to the study.The use of a wide range of advanced teaching methods, increase the chemical efficiency of the concept of classroom teaching, students learning the concept of the chemical at the same time, gradually develop from the intrinsic nature of things begin to detect the external appearance of the habit of thinking. Students step by step from the summing up of things in the law of contact, from the law's ability to forecast new knowledge and habits. After students lay a solid foundation for scientific research.
