The Application Of Classification Concept In The Junior Middle School Chemistry Recitation

The middle school chemistry curriculum standard put forward that, the compulsory education chemical basic courses in order to improve the scientific literacy of students as the main aim. The core idea of modern elementary education curriculum reform is take the student as the main body and the teachers as a guide, based on students' development. Middle school chemistry course of study is an important part in the process of basic science education, should aim at cultivating the students' scientific thinking, to form a correct concept of the basic disciplines, for students to set up the correct world outlook and methodology of science and lay a solid foundation. At present, middle school chemistry curriculum has been from the traditional teaching, to the concept of "construction" as the main body of teaching process, which can effectively promote students' cognitive development.This project apply concepts of classification in the junior middle school chemistry curriculum review process, in terms of junior high school students the specific chemical knowledge classification as a carrier to cultivate students view, and to probe the construction of classification concept for junior high school chemistry recitation of the influence and effect. At the beginning of the study through literature study, combing guiding the related education teaching theory of the present study, the meaning and characteristic of chemical classification concept. Through analysis of the characteristics of recitation and the content of the junior middle school chemistry teaching, put forward the design which based on the concept of classification teaching, and applied to the practice of teaching. The study found that the concept of classification can improve the students' learning achievement, improve the ability of solving problem and the scientific inquiry ability, helps the student to construct knowledge network in dependent.
