Practical Research On The Connection Of Chemical Concept Teaching In Junior High School

Formulated by ministry of education of our country "the ordinary high school chemistry curriculum standard (experiment)" (2003) clearly pointed out: ordinary high school chemistry course is with the nine-year compulsory education stage"chemistry" or "science of corresponding basic education courses. In view of the important position of chemical concept in chemistry learning and its abstractness,periodic and systematic characteristic, therefore, this part is the focus of the middle school chemistry learning, but also the difficulty. Grade involved in chemistry teaching in chemistry concept teaching part, due to the class teacher ren's attention degree is not enough, especially for student to study the methods of chemical concept lead does not reach the designated position, the teaching method is given priority to with single direct infusion teaching, students learning chemistry concept feel boring,affect the students in the initial stages of learning chemistry in chemistry learning interest and confidence. Many students after entering high school, because of the high school chemistry concept more and more difficult and more abstract, chemical results appear obvious drop, lose interest in chemistry learning and confidence.The author based on the theory of cognitive development and the theory of the zone of proximal development using the methods of questionnaire investigation and case study, this project is studied. Through the study found that While there are many reasons that cause this problem, but the root cause lies in the high school chemistry teaching ideas and methods, especially the chemistry concept teaching cohesion treatment inappropriate or inadequate.The author found that study in high school chemistry teaching practice should make full use of education of the concept of the guidance of teaching theory in the teaching, pay more attention to students' learning method and the teaching method of chemical concept. To according to the characteristics of the textbook compiling and curriculum standard requirements are familiar with the concept of chemistry in high school chemistry teaching material system, and USES the concept formation and concept assimilation permeable chemical concept learning strategies, selective attention strategy and strategy of creative thinking, good control of the teaching of chemical concepts, the breadth and depth, the content of the handle of the relationship between the high school chemistry concept and cohesion, to overcome the abstract concept of chemical difficult for students to learn chemistry. Design the most suitable for students' thinking in the teaching process, combined with a variety of teaching methods to improve the teaching quality of chemical concept. Let the students in learning to learn at the same time get into see the essence through the appearance of the concept of chemical nature through agent representation method of creative thinking and habits. Can cultivate students from common things and phenomena and summing rules by law to be able to infer the ability of new things and phenomena, for the students lay a solid foundation for life-long learning and development.
