Study On The Post-class Exercises Of High School Physics Thxtbooks

After-school exercises are an important part of textbooks.Throughout China,many sets of high school physics textbooks have set up after-school exercises.Whether it is the setting of after-school exercises in textbooks,the layout of after-school exercises,or the affirmation of the role of experts and scholars in textbooks,it reflects the importance of after-school exercises.What are the characteristics of the after-school exercises set in the textbook? Can the after-school exercises reflect their importance and role in the use of teachers and students?The curriculum standard is the basis for the preparation and setting of textbooks after class.The use of teachers and students is the feedback of after-school exercises.This study selected the after-school exercises in the compulsory course of the Pedagogical High School Physics Textbook as the research object.According to the relevant policy documents and the new classification theory of Bloom's educational goals,the theoretical construction of the post-class problem analysis framework is combined,and the text analysis of the after-school exercises is combined with the use of investigation and research.From the three aspects of the textbook preparation characteristics after the class,the textbook after-school exercises and the consistency of the curriculum standards,and the use of the textbook after-school exercises.Research shows:(1)According to the text analysis framework of after-school exercises,the analysis is based on the dimensions,categories,backgrounds,openness,knowledge level,and level of understanding,and the amount of problem-solving exercises is moderate.After-schoolexercises can basically cover the knowledge points of each chapter;The types of after-school exercises vary,mainly based on comprehensive application questions,calculation questions and open questions.The setting of the after-school exercises reflects the requirements of the curriculum standards for the design of the exercises,and reflects the educational ideas of the writers.(2)For the consistency of after-school exercises and curriculum standards,the study found that after-school exercises are based on the level of “understanding,” “application,”and “analysis”.The cognitive level of curriculum standards is mainly “memory”.And the level of "understanding" is dominant.From the perspective of each content topic,there is a consistent relationship between after-school exercises and curriculum standards.From the perspective of the two textbooks after the compulsory course,the design of the after-school exercises at the level of cognition is higher than the curriculum standards.(3)Research on the use of after-school exercises for teachers and students found that teachers and students basically recognize that after-school exercises have the function of consolidating knowledge.However,due to different factors such as economic level,education level and population density in different regions of the country,the level of students in different types of schools(key middle schools,ordinary middle schools)and students' ability to receive knowledge are different,and the after-school exercises cannot meet the needs of all teachers and students.Teachers and students will selectively use after-school exercises.After-school exercises focus on the application of basic knowledge.Although the types of questions are diverse,the setting of the exercises lacks gradients.There are a certain number of open questions and experimental questions that are difficult for teachers and students to grasp.And there are differences between the after-school exercises and the exams,exams,and college entrance examinations,and the lack of orientation for the entrance exams.Finally,summarize the conclusions of each research section and propose suggestions for the preparation of after-school exercises.
