Quantitative Research On The Organization Of Sino-US Junior High School Science Curriculum

With the rapid development of science and technology and the continuous updating of curriculum ideas,educational experts have put forward new requirements for students'learning:students' learning of knowledge is not limited to knowledge and understanding of knowledge,but rather to develop students through knowledge Scientific literacy.However,the difficulty of teaching materials is an important factor affecting student learning,in recent years,China has been implementing a new curriculum reform,in order to change the teaching model to reduce the difficulty of teaching materials.Practice results show that:changing the teaching model to a certain extent,help to reduce the difficulty of learning,but can not completely reduce all the difficulties.Such as:because of the order of the textbooks themselves caused by the difficulty of learning students can not be achieved by changing the teaching model.At present,many studies are from the perspective of qualitative analysis of the order of teaching materials to reduce the difficulty of learning,this qualitative analysis can not be more detailed reflection of teaching materials layout.This paper uses the quantitative research method to study the order of the Chinese and American junior middle school science teaching materials,puts forward the concept of the five elements in the process of curriculum advance,and gives the model of the vertical organization of the curriculum.The main research includes basic research and core research,the research contents are as follows:1.Basic research is mainly Chinese and American junior high school science curriculum standards.A comparative study of curriculum standards,contents and objectives from Chinese curriculum.2.The use of curriculum content organization theory,that is,curriculum content organization principles and methods of curriculum quantitative parameters of the analysis,refinement,modification,the formation of a complete curriculum vertical organization of quantitative tools.3.According to the results of combing domestic and foreign literature,the "unit page number" and "unit hours" are used to quantify the surface organization unit and construct the surface tissue quantization tool.4.Based on the scientific teaching materials,quantitative research for the method,carried out the Sino-American junior high school science curriculum deep and superficial organization research,and through the original curriculum organization quantitative tools and modify the parameters after the organization of quantitative tools on the mathematical "number" and "collection Based on the Kendall harmony function,the paper analyzes the letter and validity of the quantitative tools after modification,and applies the quantization tool to study the order of scientific arrangement of Chinese and American junior middle schools,Analysis of the characteristics of the textbooks of the two countries.
