Analysis And Teaching Practice Of After Class Exercises Based On Bloom’s Taxonomy Of Educational Objectives

With the deepening of the new curriculum reform,China’s educational ideas and methods are also developing and improving.As the main carrier of education and teaching,textbooks have undoubtedly become the key research object.In order to meet the requirements of talent training in the new era,educational experts and scholars have done a lot of research work on textbooks.However,the research on after-school exercises mainly focuses on the preparation and teaching of exercises,ignoring the importance of exercises for the cultivation of students’ cognitive thinking.Therefore,this study adopts the methods of literature research,content analysis,investigation and experiment.In the exercise analysis stage,based on Bloom’s taxonomy of educational objectives,this paper takes the after-school exercises of the compulsory module of chemistry in senior high school of new education edition as the research object,classifies and statistically analyzes them from the dimension of cognitive process,and on this basis,some strategies for cultivating students’ higher-order thinking are proposed by using exercise teaching.The study found that the setting of exercises conforms to the law of students’ cognitive development,and basically meets the requirements of senior high school students’ thinking development.It has a good correspondence with the curriculum standards in the dimension of cognitive process,but most of the exercises at the "understanding" and "analysis" levels do not pay enough attention to the cultivation of students’ high-order thinking.In the preparation and analysis stage,understand the application status of Bloom’s taxonomy of educational objectives in teaching and the teaching status of chemical exercise class through questionnaire survey and interview.The survey found that the application of Bloom’s taxonomy of educational objectives in teaching is not optimistic,but many teachers show that they support and are willing to try to use this theory in teaching.In addition,the current teaching concept and method of chemical exercise class need to be improved.In the practical analysis stage,three teaching design examples of chemical exercise class are constructed and teaching practice is carried out.The practical results show that the teaching design of exercise class constructed from the dimension of cognitive process has achieved practical results,which is conducive to cultivating the comprehensiveness of students’ cognitive thinking,so as to improve students’ performance,which reflects the feasibility of the teaching design of exercise class in this study.Based on this research,we hope to provide theoretical basis for educators in exercise teaching research,provide reference examples of exercise class teaching design in teaching practice.
