The Consistency Analysis Of The Post-class Exercises And Curriculum Standards Of High School Physics Textbooks

The physics curriculum standard of ordinary high school is the guidance document of physical education,and which is the basis of physics textbook compilation,teaching and examination evaluation.Physics textbook exercises are an indispensable part of textbook,which plays an important role in students' self-learning and teaching feedback.The research of alignment between physics textbook exercises and curriculum standard is instructive in revising of curriculum standard and textbook.The major methods and contents in the paper are as followed:The author used research approaches of literature survey and the method of content analysis to analyse the consistency between the ordinary high school physics curriculum standard and the after-school exercises of the current PEP physics textbooks for high school about compulsory part.Based on research approaches of literature survey,the author knew the project research status and ensured the objects of study and research tools.Based on the method of content analysis,the author made qualitative comparison of the physics curriculum standard's ideals and physics textbook exercises' compilation.And the research made the quantitative study of alignment degree by Webb Model and SEC Model.The author used Webb Model to analyse the alignment between them in the four dimensions,such as categorical concurrence,depth-of-knowledge consistency,range-of-knowledge correspondence and balance of representation.What's more,The author used SEC Model to calculate the consistency coefficient about every subject and whole compulsory part to judge the consistency degree.Finally,the author drew their topographical maps and bar charts to compare the differences between them detailedly.The main conclusions in the paper are as followed:Firstly,in the curriculum idea,the standard and the after-school exercises are coincident.They both embody the aim to paying attention to the basis and improving the students'scientific literacy.Secondly,from the Webb consistency analysis results,categorical concurrence are good.However,depth-of-knowledge consistency and range-of-knowledge corresponde-nce and balance of representation in every subject are different,and the alignment degree of two dimensions is not high.Thirdly,according to the results of SEC consistency analysis,the consistency coefficient between curriculum standards and after-school exercises of textbooks reached an acceptable level of consistency,but it is not high.To improve the consistency degree about the compulsory part,we should improve the consistency degree about the subject,for "Projectile motion and circular motion" and "The achievements and limitations of classical mechanics",which did not reach an acceptable level of consistency.By drawing their own topographic maps,we found that the difference between them in the proportion of weight distribution is larger.By drawing the column chart,the author compared them in content subject dimension and cognitive dimension.In content subject dimension,we found that after-school exercises of textbooks pay more attention to the two themes about "motion description" and"projectile motion and circular motion" than curriculum standards,but the degree of emphasis on the theme about "achievements and limitations of classical mechanics" is lower than the curriculum standards.In the cognitive dimension,we found that the after-school exercises of textbooks pay more attention to the requirements of"understand" and "apply" and other high cognitive level,but the number of after-school exercises about the requirement of "remember" emphasized by curriculum standard is less.Fourthly,the author compared the Webb consistency analysis and the SEC consistency analysis,and found that the two complement each other and provide arguments for each other.At the same time,it confirmed the credibility of the results.
