Research On The Investigation About Alternative Frameworks Of "Oxidation Reduction Reaction" In High School Chemistry

In the whole process of high school,usually involves many basic concepts of learning.Students before learning chemical concepts,has a certain practical life experience and knowledge,in the minds of some subtle form and scientific concepts are not the same or opposite ideas,the researchers said these ideas "alternative frameworks",its presence may affect students' learning and problem solving ability.The redox reaction of knowledge is abstract and difficult,students in the concept of the learning process,produced a variety of alternative frameworks,this will affect their learning.So the other chemical,We need to find out the possible existence of students' alternative frameworks,analyzes the cause and take effective teaching strategies,changing students' alternative frameworks.This study based on the literature review,through the analysis of the redox reaction related content,access to relevant information with talking with teachers and students to practice in the preparation of the questionnaire for teachers and students.Through the analysis of the relevant questionnaires for teachers and students,the students in the concept of reduction reaction of oxidation different ideas.On the redox reaction in the presence of alternative frameworks summary,analysis of its causes,and put forward the relevant suggestions,so as to change the students' ideas,reduce the alternative frameworks related concepts exist.
