A Study On The Causes Of Learning Difficulties And The Teaching Strategies Of "Redox Reaction"

The chemical concept manifests the reflects of the Chemical situations and nature.Teachers only let students understand these Chemical Concepts clearly, We can makestudents further to recognize things and their laws.Limited by their knowledge level andthinking characteristics,Students generally feel difficulties in the study of the Chemicalconcept when they move to senior high school. Redox Reaction is one of the most basicconcept throughout the course of the high school chemistry. This part of knowledge is vital.So find the difficulties in Redox Reaction learning, insight into the causes of these, and findeffective teaching strategy is helpful for students to build up the correct concept.This article mainly includes the following seven parts:The first part:the author explaines the purpose of this article and pointes out that Theimportant status of the Redox reaction and the problems existing in the teaching of Redoxreaction.The second part:the author makes a journals reviewed.The article expound the relevanttheoretical researches.It Including the definition of learning difficulties, the type of learningdifficulties and main causes.According to characteristics of chemical disciplines,This articledefinite the study problem of chemical conceptsThe third part: the author mainly makes explanation of the study purpose and methods.The fourth part:This paper analyses the Chemistry new curriculum of the RedoxReaction.The paper mainly discusses the knowledge hierarchy of Redox Reaction andthe evolution of Redox Reaction.The fifth part:survey and analysis of the learning difficulties of Redox Reaction.Usingsurvey questionnaire compiled by the Redox Reactions to test students.The high grade370students of the affiliated high school of shandong normal university are as samples.Usingspss20.0on the result of the test statistics.Through data analysis, it is concluded the learningdifficulties and reasons in the learning of Redox reaction. The sixth part:The teaching strategy of learning difficulties in Redoxreaction.Combined with the analysis of the learning difficulties and the reasons, the paperputs forward the teaching strategy about that.The seventh part:we discussed and prospect the problems existing in the thesis.
