Research On The Teaching Design Of Probability Unit Of Senior High School Mathematics Based On UbD Theory

The mathematics curriculum standard for Senior High School(2017 edition revised in 2020)points out that the achievement of the core literacy level of mathematics subject is not achieved overnight,and has the characteristics of phases,continuity and conformity,teachers should not only pay attention to the teaching objectives of each class,but also pay attention to the theme and unit teaching objectives,and make clear the contribution of these objectives to the development of core literacy.The core literacy education is the core theme of the current educational reform,so the unit teaching based on subject competence is not only the basic response to the core literacy education,but also the realistic need to push the core literacy to the ground.The American Doctor of Education Guerrant Wiggins and John Jay mcgregor’s understanding by design,similar to our current educational reform,aims to promote students’ deep learning,to improve the core quality of the discipline provides the theoretical foundation for unit teaching.Since the new curriculum reform,“Probability” in the teaching of the increasingly prominent status of high school mathematics as one of the important content,but also the required examination of the content.Therefore,this research mainly aims at the probability of chapter 7 of the first volume of 2019 Beijing Normal University Edition High School mathematics compulsory course to carry out the high school mathematics unit teaching design research based on the UbD theory,has the certain educational value.This research is divided into three parts,the first part is theoretical research,on the basis of literature analysis,the theory of UbD and unit teaching at home and abroad were analyzed and summarized,then the connotation and related concepts of UbD theory are expounded in detail,the framework of UbD unit teaching design is summarized,and according to this framework,the concrete unit and class hour teaching design scheme of probability unit is carried out.The second part is the practical application part.On the basis of analyzing the students’ achievement in mathematics,two parallel classes are selected to carry out the teaching practice research of probability unit based on UbD theory,this paper analyzes the feasibility and validity of UbD unit teaching design from three aspects: the comparison of unit test scores of two classes,the questionnaire of experimental class and the interview with teachers.Finally,the sixth chapter is the conclusion of this study,shortcomings and future prospects for the statement.The conclusions of this study are as follows:(1)students and teachers have a high degree of approval for the UbD-based high school mathematics instructional design;(2)compared with the traditional instructional design,based on the UbD theory of high school mathematics teaching design can enhance students’ understanding,grasp the basic knowledge of the effect,so as to improve students’ academic performance,and thus enhance the teaching effect.
