High School At Different Stages Of The Redox Reaction Of Teaching Issues And Strategies

In middle school Redox reaction occupied a very important position, the secondary chemical materials throughout high school chemistry teaching, which is always the key and difficult.In the chemical compulsory 1, compulsory 2 and elective 4, they have related contents of Redox reaction involving knowledge teaching research, this paper systematically divided into the following four parts:The first part is the introduction section, this part analysis O 'clock, Sue o 'clock, Shandong o 'clock three different versions textbook knowledge Redox reaction to the of the content arrangement, and it understand the content standards from different stages of Redox reaction, and clear read the new curriculum standard requirements and deep breadth. According to the new curriculum spirit, the teaching of Redox reaction develop students at the material and its classification, reaction and its applications, energy conversion, reaction system, the construction of Redox reaction follows related knowledge system, and introduces the knowledge systems Redox reaction teaching value.The second part is the literature review and research suppositions. This part of the relevant domestic and foreign Redox reaction of teaching in the teaching and teaching strategies material are reviewed, and puts forward the purpose of the research significance, content, method and assumptions.The third part is empirical studies, this paper focused on the following aspects of research:Research 1:teaching problems and strategy research of compulsory 1a module Redox reaction. Through the questionnaire survey, a freshman in learning behaviour is required before a Redox reaction, and according to the base of knowledge analyzes students' knowledge base of traditional syllogistic teaching organization form problems and how to make the student to grasp the essence of Redox reaction is gain and loss, electronic, in-depth study such problems in teaching, and puts forward the teaching strategy, finally and analysis of teaching Redox reaction function value, etc.Research 2:compulsory 2 module and Redox reaction relevant teaching problems and the teaching strategy research. Compulsory 2 "chemical energy and power" section battery is the formation of the central concept nature of Redox reaction develops and application in literature, investigation and the interview YuanDianChi concepts learned in classic YuanDianChi parlance usually copper zinc YuanDianChi concept. For example construction So easily ignored explain about Redox reaction, cause the penetration of nature YuanDianChi principle of the students to understand not profound enough, not the composition of institution transference YuanDianChi research other, aiming at the problems in teaching to make teaching strategy research.Research 3:chemical reaction principle modules existing in the teaching of the problems in teaching and strategy research. Take four of the application of relevant Redox reaction-how basic knowledge part, electrochemical cope better elective module and compulsory module linking problem, how application knowledge Redox reaction, and according to know reaction system Redox reaction phenomena and problems in actual interpretation and analysis are key of this chapter.The fourth part is the conclusion and revelation, finally to Redox reaction of thinking and doing the whole teaching reflection.
