Theoretical And Conceptual Teaching Junior High School Chemistry Research Schema

Chemical concept is the chemical phenomena of abstracting,reflecting the nature of the chemical phenomenon and chemical fact knowledge,which reveal the essential attribute of material. Chemical concept is the core part of junior high school chemistry, and chemistry discipline study plays a decisive role. With the deepening of new curriculum reform, the foundation education reform trend sweeping the country. Curriculum advocates, chemistry teaching should not be too much emphasis on definition of the concept of rigor. New standard to reduce some of the specific definition of sexual concept,reduce the burden of the memory of defining concepts.In learning chemistry discipline, students should to understand the basic concepts clearly and accurately.You can learn chemical principles,knowledge element compounds and chemical equation well. Development level is still in the junior middle school, students think from image thinking to abstract logical thinking,which do good to students; At the same time, the bad learning habit of some student also makes chemical concept learning difficulties; The ways of teaching chemistry concept, emphasizing the practice of the homework problems, which lack of concept of teaching value also makes concept teaching difficulty. Therefore, how to make students more effectively acquire concept of chemistry is the problem that we ignore.To improve the effectiveness of the chemical concept, this article is a combination of schema and schema theory research, which from a conceptual schema structure. The relationship between the conceptual schema and the form three aspects of conceptual scheme, put forward the samples of pattern identification strategy, learning strategy and the overall construction of three kinds of teaching strategy, to service all the teachers and students.The first part of this paper puts forward the research objects and research background of this article, namely the background of new curriculum reform. In junior school chemistry concept as the research object, trying to improve the effectiveness of the teaching of junior chemistry.In this paper, the second part analyzes the new standard chemistry textbooks,which focus on the chemical concept,explaining the present situation of the current chemistry concept teaching.It points out the problems existing in the chemistry concept teaching, such as the chemical teaching material itself, the development of students’ cognitive level and concept teaching strategy related issues, identify possible direction of improving the effectiveness of chemistry concept teaching.The third part of this paper introduces the schema and schema theory, which emphasizes the relationship of the concept of schemata and chemical concept.It from the schema of structure, the relationship between the formation and schemata three angles proposed to improve the teaching strategy of chemistry concept teaching effectiveness, pattern identification strategy, the sample of learning strategy and the overall construction strategy.The fourth part of this article, according to the proposed three chemistry concept teaching strategy,which is the pattern identification strategy, sample learning strategies and the overall build the three teaching strategies,using in the concrete teaching case, namely "solid solubility", "the activity order of metals" and "atomic structure".Through the analysis shows that schema theory is helpful to improve the efficiency of the chemistry concept teaching.Finally, summarizing the research process and methods, which is teaching suggestions are put forward.
