Three Versions Of High School Mathematics Textbook "Calculus"Ontent Comparison And Evaluation

The textbook is an important resource for teaching.There are five versions of textbooks in China, I choose People’s Education Press(P), Jiangsu Education Publishing House(S), Beijing Normal University Press(B) as case, comparing the elective content of calculus in2-2.The essay uses the comparison research, content analysis, qualitative analysis and quantitative analysis, analyzing the material from the following six aspects——content arrangement, knowledge module, knowledge organization, situation, representation, reading materials, finding the similarities and qualities, providing useful suggestions for teachers and students, achieving better teaching and learning.From the macro comparison, three versions of the textbook is very similar in content, but from the microscopic point of view, P is concise and rigorous, B is strong levels, S is easy to understand, but lack the application of definite integral, lacking training application consciousness; In the knowledge module, three versions of the textbook consistent "the fundamental theorem of calculus" with "derivative" and "integral"; In the knowledge organization, the essay has brought forward the exposed problems from seven aspects, as a result, they are very distinctive, in the "derivative concept", S teaches the version with the scene into cause cognitive conflict thus derived concept, but in the average rate of change on the issue is not as to abstract R&B; S&B are in detail in the "derivative operation", S uses diagram of the program, B makes a trial and error description, P is explained on the derivative from physics and geometry, to help understand; In the "application derivative in the research function", increase of derivative0is on the extremum point of P, has manifested the teaching material pays attention to the cultivation of thinking ability in Mathematics; In "the concept of the definite integral" and "the fundamental theorem of calculus", all three versions use of information technology in teaching, R focuses on the process of formation of the concept, mathematical rigor and formal operation; B has volume calculation in "simple application of definite integral", increasing the difficulty, challenges but cohesion university textbooks; In the situation, R uses "diving" integrally; In the way of presentation, three versions of textbooks use symbol representation most; In reading material, S is the most abundant, reflecting the cultural value of Mathematics.
