The Comparison Between The New And Old Physics In Junior High School Published By People's Education Press

In order to consolidate the new round of curriculum reform, thephysics curriculum, advancing with the times, to implement thenew physics curriculum standard,in the fall of2012.The writingof the physical teaching materials should conform to the conceptof physics curriculum standard.In terms of physical teachingmaterials, although it is the main carrier of physics knowledgecontent, but not equivalent to the knowledge system of physics.Touse textbooks properly and efficiently, the teacher must clearlyknow the ideas and the basis of writing teaching materials, andclear teaching material's characteristic, to master the knowledgestructure of the teaching material. These are not just do a goodjob in teaching, basic work to improve the quality of physicsteaching, and can only be done through scientific analysis of thephysical teaching material.From old and new junior middle school physics teaching materialas the starting point, this paper adopts comparative method andstatistical analysis method to the class changes before and afterare the two sets of junior middle school physics teaching materialson the longitudinal comparative study, the research content mainlyfor two aspects.Study one of compares the structures of the teaching materialsbetween the new and old teaching material published by People'sEducational House.The study shows Structure is mainly compare theold and new teaching material organization structure, subjectstructure and cognitive structure?Organization structure is alist of old and new teaching materials, layout design, column setup,diagram, experiment design, the problem sets. Subject structureis comparing old and new knowledge module and chapters in the text.Cognitive structure is the old and the new teaching materialcognitive development level, cognitive strategies, emotionalfactors. New version of teaching materials in the structure oforganization directory number of sorting, problem sets, columnnumber, pictures on the set type, number of experiments and waysare larger changes, especially the picture of the experimental class and the change of the design of experiment,it related tocurriculum standard requirement for scientific inquiry ability.New teaching material in the arrangement of the moduleconfiguration and chapter knowledge have great changes, especiallymechanical parts of the layout, the change is based on the students'cognitive development levels. In cognitive structure, the newteaching material without substantial change, just a slight changein the embodiment of the emotional factors.Study two of compares the breadth, depth and level of difficultyof the teaching materials between the new and old teaching materialpublished by People's Educational House.The study shows that thedifficulty of the junior middle school physics of old and newteaching material part corresponding to each other, the breadth,the depth, corresponding to each other of some parts of match degreeis high, some part of the alignment is bad, such as part of thenew teaching material mechanics scope to expand, reduce theteaching time, its difficulty is significantly higher than themechanical parts of the old teaching materials.But comprehensiveof old and new teaching material's breadth and depth, the coursecurriculum difficulty found roughly tallying with the old and thenew one, even if several parts are different.
