Research On The Teaching Practice In The First Round Review Of Senior Physics Based On Knowledge Classification

The first round review of senior physics is the key period for locating and making up the deficiencies,improving knowledge structure and enhancing the ability to solve problems.However,the conventional practice is that the teacher leads the review in accordance with the order of teaching materials to review the contents of the college entrance examination outline,such as listing knowledge points,lecturing examples,making students do exercises,and commenting exercises.These practices do not fully consider students' learning situation and learning mechanism of different knowledge,resulting in low study efficiency.In this thesis,from teasing the goals and analyzing the current situation of the first round review of senior physics,combined with literature research,the author found that the theory of knowledge classification can efficiently instruct the process of review teaching in the Senior Year`s first round physics review.In recent years,based on the theory of knowledge classification,the author divided physics knowledge into declarative knowledge,procedure knowledge and strategy knowledge and put them into practical teaching in the first round review and came up with a new teaching design which is to detail review goals,optimize examples and exercises and diagnose student`s problems in learning by using the theory of knowledge classification.In the help of some specific cases,the author also interpreted the teaching plan based on the theory of knowledge classification in the first round physics review,which developed stages of knowledge learning and models of knowledge classification.Based on the features of the study of different knowledge,the author explored the strategies of first round review of three different kinds of knowledge of physics in practical teaching.(1)Declarative knowledge describes Physical phenomena,physical concepts and physical laws.The purpose of reviewing declarative knowledge is to improve the knowledge structure on the basis of understanding.Therefore,it is stated in the article that using the first organizers can promote students' understanding of declarative knowledge and it also can promote the structure of declarative knowledge by visualization of thinking with the help of charts,mind mappings and so on.(2)Procedural knowledge is the knowledge of how to solve physical problems.It can be mastered by practicing.Teachers can activate students' thinking through one question with variants,one question with multiple solutions,several questions with one solution,etc.thus enhancing students' thinking capacity.(3)Strategic knowledge helps students how to learn knowledge.so,in this study,the teacher helps students review the strategic knowledge by physical method and metacognitive regulation.Based on knowledge classification,it puts forward the first round physical review teaching designs by using the knowledge classification theory to refine the review,optimizing the choice of exercise and diagnosing the learning process,combined with specific cases.The results before and after the test by using the statistical software SPSS 17.0 analysis and the use of unequal control group before and after the test design show that: compared with the conventional review,the first round physics review which is based on knowledge classification can improve students' ability of solving problems,and it is of great significance for Medium-Ranking students.
