Design Of Unit Teaching Design Based On UbD Theory

The "Ordinary High School Curriculum Program(2017 Edition 2020 Revision)" promulgated in 2020 clearly stipulates that the training goal of ordinary high schools is to further improve students’ comprehensive quality and focus on developing core literacy.New goals correspond to new teaching,and new teaching needs new design.Due to the characteristics of stage,continuity and integration of students’ core literacy level in mathematics,teachers should pay more attention to the teaching design with unit as the carrier.However,how to design unit teaching has become a difficult problem.At this time,the "Ub D" theory,also known as reverse teaching design,provides an operable template for teachers’ unit teaching design.Teaching design based on Ub D theory can open up the current difficult situation of unit teaching design and implement the requirements for developing students ’ core literacy after the new curriculum reform.How to study the teaching design of high school mathematics unit under Ub D theory? The specific research process is as follows:After sorting out and analyzing the literature by using the literature research method,this paper investigates the current situation of unit teaching design from the feasibility of unit teaching design theory research based on Ub D theory,and analyzes the research results.On this basis,the general process of unit teaching design based on Ub D theory is proposed.The process includes five steps: analyzing curriculum standards,determining unit teaching objectives,selecting evaluation evidence,planning learning activities and dividing class tasks.Finally,the calculation unit of plane vector is selected,and the unit teaching design practice of this unit is carried out by using the general process of unit teaching design based on Ub D theory,which preliminarily shows that the unit teaching design of high school mathematics under Ub D theory is practical.Finally,three high school mathematics teachers with rich teaching experience were interviewed.The results show that the unit teaching design under the guidance of Ub D theory can better improve the unit teaching effect.Nowadays,the research on unit teaching design around core literacy is endless,but the research on the implementation of unit teaching design to high school mathematics teaching design needs to be further explored.Therefore,this paper explores the method of high school mathematics unit teaching design based on Ub D theory,and forms a specific and operable unit teaching design process.Based on this,the unit teaching design of "plane vector operation" under Ub D theory is compiled,which enriches the relevant cases and provides a case reference for high school mathematics teachers to explore the new form of unit teaching design.
