Study On The Situation In Exercises Of High School Physics Reference Books

Through solving exercises,students will deepen their understanding of their knowledge,cultivate their scientific thinking and understand the relationship between physical knowledge and science,technology and society.Teachers can understand the effect of teaching through students' problem-solving exercises,and arrange the next teaching according to students' mastery.Therefore,the exercises have an important meaning.With the continuous practice of curriculum reform,many aspects of physical education have undergone gratifying changes.As an important carrier of exercises,there are more and more exercises that are based on real-life situations.The emergence of situational exercises improves the connection between physical knowledge and science,technology and society,and adds interest to physical exercises.But the quality of the exercises on the teaching auxiliary is very different.The situational setting in teaching auxiliary exercises is very important for the quality of exercises.This paper takes exercises in fifth chapters and seventh chapters of 12 teaching aids in high school as the research object.First,classify the 617 situations involving different exercises,summarize 289 different situations,and classify different situations.Then 200 selected and 200 calculation questions were selected randomly,and the situation was studied from three aspects of authenticity,science and clarity,and the results were analyzed.In addition,two in-service high school teachers were asked to review the problems and cases that had been preliminarily selected.After many modifications,the final research results obtained consistent opinions.It is found that the quality of situational exercises commonly used by senior high school students in Haikou is generally better.The proportion of problems with situational problems was 5.75%.The authenticity is manifested in three aspects: the situation is divorced from reality,the data do not conform to reality,and the model diagram does not conform to the reality.Scientific problems are manifested in three aspects: situational errors,misplacement of Situational Questions,and incorrect setting of situational answers.The problem of clarity is manifested in two aspects,which are not clear,inaccurate,unnecessary scenario or situationmodel.As an important reference book in student's learning process,teaching assistant will cause confusion or obstacle to students' normal learning.Therefore,the compilation of the teaching assistants needs to be improved.The setting of the problem situation should be more rigorous and scientific.When using reference books,teachers need to review exercises to ensure the authenticity,scientificity and clarity of situations in exercises.
