The Theory And Practice Of Improving The Teaching Quality Of Electrochemical Chemistry In Middle School

With the new curriculum reform, we teachers also more and more to reflect onsome problems existing in teaching in the new curriculum, the teaching materialarrangement to ponder, to explore the classroom teaching more efficient. Theelectrochemical content is an important part of high school chemistry, in the requiredcourses and study courses are involved. Due to the chemical knowledge and scattered,the topic is very abstract, students generally feel more difficult, but is the annualcollege entrance test form. How to effectively integrate compulsory and electivecontent, improve the electrochemical teaching quality, these are worth us to explorein depth.This study mainly from the following aspects: first, the Xundian national highschool, high school students electrochemical learning situation, investigation ofpresent situation of teaching; secondly, learning theory, and find the meeting point ofthese theories and electrochemical teaching, and their integration into the audio-visualteaching; then, studies the countermeasures against secondary electrochemicalTeaching in Xundian County National; then, in the form of case studies of caseteaching experiment and teaching electrochemical display; finally carries on theappraisal to this study used comparative analysis method.Through the research and practice of nearly two years, and achieved good results.In the2013-2014school year next semester final examination, the study on theteaching method of high experimental class223class and experimental class203grade class chemical scores for the school with the level of the first grade. Theexperimental class class223Senior1chemistry average beyond contrast class224class4.3class203chemistry; experimental class average beyond comparison class204class4.9. Relates to electrochemical content in the examination score ofexperimental class is much higher than the contrast class, class223, class224electrochemical score higher than6.8, class203, class204electrochemical average-7.3. The class223and class224Z test value is2.11, showed that there were significant differences; Z test was performed on203and204classes, test value is2.23, also showed that there were significant differences.
