The Integrating Practice Research On The Teaching Content Deep Breadth Between People Of High School Chemistry Required And Elective Modules

The general high school chemistry course adopts the modular teaching Settings, in order to meet the students’ interest and development needs.But in the actual teaching of chemistry for high schools,because a lot of topic content also appears on the compulsory modules and elective modules,it is very difficult for teachers to grasp the deep breadth of the two.Compulsory teaching often introduces the relevant content of electives,it is not enough to integrate the knowledge that is learned during the course of the elective,resulting in the disconnection of knowledge,lead to a lot of students think chemistry is difficult.Therefore, in the actual teaching, the teaching of chemistry for high schools are required and elective deep breadth of integration has important practical significance.Firstly,this research is based on the analysis of literature and related theories,defining the three core concepts of deep breadth,teaching content of deep breadth and integration,and to determine the required and elective teaching content deep breadth integration principles.Secondly,taking the theme of "chemical energy and electric energy" as an example,from the requirements of curriculum standards,compulsory and elective modules of the functional orientation, the theme of the content of the organization, the theme of the depth and breadth of topic content,etc.and to teach version of high school chemistry compulsory and elective module teaching content breadth and depth of integration for the theoretical analysis.Again, in Qingyang City,Gansu Province, a class high of model school 6~9 four parallel classes of students as the research object,the use of survey method for four classes of students to test the concept of the original battery,according to the survey results of students’ learning situation,design of required and elective "primary battery", "chemical power" teaching the general idea of the integration of deep breadth,thereby establishing the integration of teaching cases and implementation class.Finally, the design of the "original battery" after the integration of teaching test and "chemical power" after the integration of teaching test questions for the integration of the implementation of the results of the case analysis and evaluation.Research shows that according to the curriculum standards and materials grasp the breadth and depth compulsory and optional modules teaching content is the key to the integration of teaching;combining students learning situation, adjust the teaching ideas,integrating teaching, which is advantageous to the required and elective electrochemical knowledge of cohesion and smooth transition;from the required and elective modules offunction orientation, theme and content of organizing ideas of integrating teaching contents deep breadth, and is conducive to students mastery of core knowledge and teaching difficult point of breakthrough, which is helpful for students to construct knowledge network.
