The Study Of Electrochemistry In Middle School Basing On "Overall Construction" Theory

The core of the system theory is the concept of integrity of system."Overallconstruction" theory is the application of this thought in the teaching. In this paper,"the overall construction" theory as a guide to research electrochemical in middleschool chemical teaching system, teaching strategies and methods derived therefromoptimization. At the same time to other modules also did some preliminaryexploration, as the starting point of the future study.Among the elements of teaching process and teaching process and teachingenvironment should closely cooperate, coordinate, the formation of a unified,coordinated, balanced state in the teaching activities, this is the basic idea of"overallconstruction" teaching theory. Electrochemical is an important part of the middleschool chemistry knowledge system, it relates to the redox reaction, energyconversion, the electrical knowledge, knowledge transfer to technology and so on,content rich, complex relationships, is one of the emphases and difficulties of themiddle school chemistry teaching. The teaching system of electrochemical teachersand students, teaching resources can be seen as a system, which exist in the teachingsystem of all, electrochemical knowledge system is mainly composed of primarybattery principle, chemical power, the principle of electrolysis, electrolysis, theapplication of metal corrosion and protection, transformation of these knowledge andunified in redox reaction and energy, these knowledge can be as small as a whole,each a small overall internal and there is a unity in its own, must take into account theknowledge of the overall relationship between small overall construction of teaching,but also the unity of knowledge within the small overall. With the help of"overallconstruction" theory to deal with the electrochemical teaching problems, correctlyhandle the relations between the elements in the system, teaching,contributes to theoverall consideration and overall design and implementation of teaching, the teachingprocess and effect optimization."Overall construction" based on the theory as the guidance, the above problemhas made the preliminary research and exploration, thus optimizing the teachingstrategies and methods, designing the teaching example, also puts forward therelevant problems and provide the reference for the teachers and researchers.
