A Comparison Of Examples And Exercises’ Design In High School Physics Textbooks Between China And American

This paper makes a comparative study of examples and exercises design between the PEP version senior Physics textbook and the 《Physics:Principles and Problems》.Research one makes a comparative study of examples in the positions and columns,the quantities and the type,the scenarios sources, the difficulty and the demonstration between the two physics textbooks.Research two makes a comparative study of Exercises in the positions and columns, the quantities and the type,the scenarios sources, the difficulty, the hierarchy and the sequence of the two physics textbooks.Research three makes a study of the relevance between the two two physics textbooks.This research finally gets the following conclusions:The first conclusions: ① The examples in the two Physics textbooks are provided in the following important points,and have special section; ② the quantities of examples in the 《Physics:Principles and Problems》 are than the PEP version senior Physics textbook, calculations are the main Type of the examples in the two physics textbooks; ③ the situational sources of the examples in the two physics textbooks mainly include life reality, sports, modern technology and history of physics, the 《Physics:Principles and Problems》 pay more attention to contact with real life than PEP version senior Physics textbook, and the situational sources of the example in the 《Physics:Principles and Problems》 is closer to the students’life;④ The comprehensive difficulty of the examples in the 《Physics:Principles and Problems》 greater than the PEP version senior Physics textbook, But the average difficulty of the examples in the 《Physics:Principles and Problems》 slightly less than the the PEP version senior Physics textbook.⑤ The PEP version senior Physics textbook demonstration focused on problem-solving ideas,the 《Physics:Principles and Problems》 demonstration focused on problem-solving steps and there is verification link.The second conclusions: ① The exercises are provided in section, end of section and end of chapter in the 《Physics:Principles and Problems》,while exercises are provided only at the end of the festival in the PEP version senior Physics textbook, the exercise Columns in the 《Physics:Principles and Problems》 are richer than the PEP version senior Physics textbook; ②　he quantities of exercises in the 《Physics: Principles and Problems》 are far more than the PEP version senior Physics textbook, the type of the exercises in the two physics textbooks are relatively abundant, including short answer questions, calculation, completion, mapping problems, proof problems, multiple choice questions,experiment inquiry questions and writing task, but the calculation and short answer questions based.On lab exercises, the PEP version senior Physics textbook focus on checking students’practical ability and the ability to explain observed phenomena hands-on experiments, the《Physics:Principles and Problems》 focused on students’ ability to experimental design.On writing title, the 《Physics: Principles and Problems》 at the end of each textbook chapter "Assessment" is provided with a "Technical Writing" little column,the PEP version senior Physics textbook writing questions rarely provided; ③ The situational sources in the two sets of textbooks both are relatively abundant,they focus on contact with real life, The situational sources in the《Physics:Principles and Problems》 are closer to the students’ life. ④ The comprehensive difficulty of the exercises in the 《Principles and Problems》 is greater than the PEP version senior Physics textbook, But the average difficulty of the exercises in the 《Physics:Principles and Problems》 is slightly less than the the PEP version senior Physics textbook.Exercises in different sections on the average difficulty of knowledge, the PEP version senior Physics textbook in mechanics, electromagnetic sector is greater than the 《Physics:Principles and Problems》, but in thermal, light waves, atomic physics, modern physics plate less than the 《Physics:Principles and Problems》 especially in atomic physics and modern physics is significantly less than" the 《Physics: Principles and Problems》;⑤ The understanding exercises, comprehension exercises, application exercises in the 《Physical:Principles and Problems》 are proportion of 24.05%、74.41%、1.53%, the understanding exercises, comprehension exercises, application exercises in the PEP version senior Physics textbook are proportion of 28.43%、65.38%、6.19%.⑥ The exercises in the two Physics textbooks are basically orchestrated the order from easy to difficult.The third conclusions:the Examples for exercises have good demonstration and guidance in the two sets of textbooks, while exercises for Examples have better scalability and mobility in the《Physical:Principles and Problems》 than in the PEP version senior Physics textbook.
