Study On Evaluation Of Ability Based On Redox Reaction

The main purpose of this paper is to master the development trend of students’ ability,build a perfect knowledge network,and refine the ability required by students according to the knowledge network.Combined with different ability dimensions,make research tools,and then evaluate students’ ability.The process of this study is divided into the following stages.The first step is to collect and sort out the relevant literature and journals of redox reaction teaching through network search,so as to lay a theoretical foundation for follow-up research.The second step is to comprehensively sort out the literature,combined with their own teaching experience,build a perfect redox reaction knowledge network,extract the ability required by students according to the knowledge network,and refine the ability to each teaching link to form a complete ability context.The third step is to formulate research tools according to the ability framework,test students in different periods,and improve the teaching design according to the test results.Finally,sort out and analyze the test results,draw the research conclusions,summarize and refine the conclusions,and apply them to the future teaching practice.From the four evaluations,it can be concluded that the learning process of students’ redox reaction has a certain law of change and development.Firstly,the knowledge system makes a systematic classification and an extended exploration of the essence of the response from several scattered special reactions in junior middle school to senior high school;Secondly,from the low macro recognition ability in junior middle school to the higher ability level and more dimensions in senior high school.It can be seen from the four tests that the ability level of students rises step by step,from low macro recognition ability,low micro analysis ability,low logical reasoning ability and low model construction ability to medium macro recognition ability,medium micro analysis ability,medium logical reasoning ability and medium model construction ability,and finally to high macro recognition ability Higher micro analysis ability,higher logical reasoning ability and higher model construction ability.
