UbD-based High School Mathematics Unit Teaching Design And Practic

In the era of core literacy,our education emphasizes guiding students to understand the overall knowledge and master knowledge,focuses on the development of students’ ability and thinking.UbD model(Understanding by Design)attaches great importance to "understanding",focuses on the "reverse"and pursues for the "whole".Teaching design based on UbD model starts from the big concept.Besides,the model can be flexibly applied in a class or a unit.It can be found that the UbD model fully fits into our country’ teaching guides and connects with core literacy implemented.The plane analysis geometry builds a bridge between algebra and geometry.It contains rich mathematical ideas and methods;it is also the key and difficult point of teaching.Therefore,in this study,the author chooses large units of "plane analysis geometry" as the carrier,it is valuable and meaningful to study the high school math unit teaching design based on UbD mode.The content of the study is divided into six chapters.The charter1 to 3,basedon the literature review and questionnaire analysis,the current research progress of UbD mode、unit teaching and plane analysis geometry teaching were reviewed,the current situations of the teaching design of high school front-line mathematics teachers and the mathematics learning situation of high school students in education experimental school were understood.In Chapter 4,the author took of"plane analysis geometry" the large unit as an example to design the math unit teaching scheme based on UbD mode.In Chapter 5,selecting two parallel classes according to the paper for mid-term test with teaching practice,after the end of practice,the author analyzed the feasibility and effectiveness of the new teaching model in practice by the unit test,the questions results of students and the interview of teacher.Finally,the author summarized the research conclusions,analyzed the shortcomings the paper and provided ideas and directions for the future research.Through analyzing the data of practical research,the following conclusions were drawn:1.The high school mathematics unit teaching model based on UbD can enhance the teaching effect and improve students’ academic performance.2.It is beneficial for students to construct knowledge framework and improve students’ understanding and transfer of knowledge based on UbD in high school mathematics unit teaching model.3.It is helpful for students to clarify their learning direction and task,and develop good learning habits of summarizing and reflecting by applying of the high school mathematics unit teaching model based on UbD.4.The high school math unit teaching model based on UbD is recognized and supported by students and teachers.
