Comprehending Study Designation Research For Conception System Of Oxidation-reduction Reaction

The conception is an important part of chemistry knowledge. It is also difficult to lear n and teach chemistry conception well for a long time. And it is the premise of sublimation for teaching and learning. Because the conceptions are often very abstract and difficult to understand, so we need to take certain teaching strategies during the teaching activities. It will be a bit abstract for the students about the atomic structure though they have known ce rtain type of chemical reaction in the middle school, which could not be improved even for the first year in high school. So there would be big problems for them to understand the co nceptions of oxidation-reduction reaction, the nature of the oxidation-reduction reaction an d the way to build relationships in different conceptions. And the key to solve the problems is that to know the students’ cognitive characteristics, cognitive level and conceptions’ lear ning, study how to design the teaching processes to promote the students’ better conceptio n understanding and take actions.After researching the bibliography, there is a conclusion about the current situations a bout teaching and studying oxidation-reduction reaction conception system and it is urgent to change such situation. A great many researches for the comprehending study have been done base on the theory that it is important to combine the methods and practice. And the t heoretical principle for the researches is the six dimensions with seven principles of compr ehending study. Understanding the students’views and the actual chemistry learning by lea rning conceptions of chemistry and chemistry student surveys. In order to enhance students understanding of concept, this essay study into the scene teaching strategies, teaching strat egies cognitive conflict, error analysis in teaching strategies.This essay provides teaching designations to promote the students’ better understanding about oxidation-reduction reacti on conceptions. At the same time, apply the designation to the teaching processes explore t he effects on helping the students to understand the oxidation-reduction reaction. Hope to h ave practical reference to the teaching of oxidation-reduction reaction conception system.After applying the designation to the teaching, in order to proof more about the effects from the oxidation-reduction reaction conception system to the students, we give tests according to the six dimensions of understanding study and give tests to first grade, class (2) and (9) in one of high schools of Guangxi. And use SPSS software to analyses the four dimensions and total score horizontal comparison. The analysis showed:the total experimental classes performed significantly better than the control class, and there are significant differences. Furthermore, in order to better understand the experimental class students’ knowledge understanding. With a longitudinal analysis to the student achievement in experimental class. It showed that: over 50% of the students have a good understanding of knowledge. There is another survey to the students’ chemistry study and chemistry learning conception in the late of the experiment, it showed that most of the students can accept this teaching style, and can be consider to know the knowledge well.It shows that it is possible to apply the promotion oxidation-reduction reaction conce ption system understanding to the teaching practice. The following conclusions,(1) Students like inquiry learning under teacher’s guidance, learning to master.(2) Variety of learning classroom is conducive to the enthusiasm of the students to keep learning.(3)Teaching effect is significant, most of the students understand the knowledge.Finally, this study presents thought and outlook, and further point out research has so me shortages, research space could be more.
