Research On The Use Of High School Chinese After-class Exercises Based On PBL Theory

In high school,exercise utilization has become one of the important links in the process of teaching and learning.Proper utilization of exercises can not only consolidates what teachers and students have taught and learnt,but also trains their logical thinking ability,language expression ability and other abilities.Whereas,in the practice of exercise utilization,the situation of exercise utilization by teachers and students is not optimistic,which is manifested in three major problems: the dislocation of the subject of exercise utilization,the single way of exercise utilization,and the lack of cooperative way of exercise utilization.Theory guides practice.As a kind of practical activity that teachers and students use the knowledge they have mastered to solve problems,exercise utilization can't depart from the theory.PBL theory advocates teachers to respect students' subject status and regard them as the main problem solvers,which effectively helps students to make clear and play their subject value in the process of using exercises;PBL theory emphasizes the process of problem-solving,the flexibility and openness of problem-solving objectives and methods,which effectively enriches the open utilization of exercises;PBL theory advocates cooperative problem exploration and encourages students to cooperate with others,especially emphasizes the mutual benefit between teachers and students,which effectively promotes the cooperative problem-solving.Therefore,PBL theory can be deemed as an significant guiding thought for teachers and students to use exercises.Compared with the students in junior high school,the students in senior high school are more mature in their thoughts,and their independent consciousness develops rapidly.They aspire to break away from the shackles of teachers or parents during their study or life,and always show an eager look when solving exercises.However,facing the severe pressure of college entrance examination and the urgent time,they need to struggle in the endless questions every day,so the treatment of exercises is often just the teacher's explanation.In the long run,such a "domineering" and single way of exercise utilization has largely eliminated the subjectivity,openness and cooperation of students in the use of exercises,making them too passive,rigid and zero cooperation with others.In the process of problem-solving,teachers and students may take PBL theory as the guiding ideology to realize the student-oriented open and cooperative utilization.From the perspective of the exercise utilization of Chinese in senior high school,based on PBL theory,this paper analyzes the feasibility and significance of PBL theory in guiding the use of Chinese after-class exercises in senior high school,and concretely constructs the strategies of exercise utilization in combination with the after-class exercises in Chinese Textbooks of human education edition.This paper aims at the problems which easily occurs in teachers' and students' exercises utilization,and refers to the previous relevant research achievement of exercises utilization to make a deeper level of discussion on the Chinese after-class exercises in high school.According to the basic characteristics of PBL theory,which takes problems as the basic focus,students as the main body of problem-solving and cooperation as the main way of inquiry,combined with the psychological state and cognitive level of senior high school students in the process of exercise utilization,this paper follows the three principles of subjectivity,openness and cooperation under the guidance of PBL theory and adopts the three strategies of defining the subject position of Chinese exercise utilization in high school,opening Chinese multiple ways of exercise utilization in high school,and strengthening the Chinese cooperative process of exercise utilization in high school.Under the guidance of PBL theory,this paper puts forward some practical suggestions on how to make the best of exercise,which hopes to be beneficial to the exercise utilization by teachers and students.
