The Study Of Element Concept Penetration In The Junior Middle School Chemistry Teaching

Chemical concept penetration is an important task of chemistry teaching and element concept is the important part in the junior middle school chemistry concepts.This paper adopts questionnaire and interview to analyze the teachers’understanding of the concept of "teaching" in the junior middle school chemistry teaching and the concept of element construction of students.Survey found that the current teachers’ teaching ideas, though no longer stay on the knowledge, but the knowledge of the basic concept of chemistry is a little. The concept of building of students is also uneven.The reasons of the elements construction of students is various, but one important reason is the teacher s’ teaching idea and behavior.Based on this, this paper puts forward several teaching suggestions:(1) Fully study the teaching material and curriculum standard, with "the concept of chemical elements" and the concept of "teaching" as the teaching design;(2) With element concept as a starting point, initially formed from the perspective of elements to know the world of ideas;(3) Construction of chemical elements in learning unique view;(4) The utilization of driven deep understanding of knowledge, construct element view;(5)Using concept mapping technology, and promote the construction of students view of elements;(6) Attaches great importance to the role of chemical experiment in the view of culture elements;(7)Combining the reality of life, rich view of elements in the application.1 hope the research of this paper to promote the teachers’ teaching idea from "knowledge teaching" to "teaching idea" transformation, promote the concept to include elements of understanding and using of chemical basic conception, have certain effect.
