Application Research Of High School Mathematics Unit Teaching Based On UbD Model ——Taking “Logarithm” As An Example

Since the six core qualities of mathematics were put forward,how to implement the core qualities of mathematics and change the teaching concept of teachers has become a big problem.Classroom teaching is the main position to cultivate students' core literacy.The key to cultivate students' core literacy lies in classroom change.Unit teaching design is an important way to realize classroom change.Unit teaching design is a teaching design model based on unit teaching,which has unique advantages in the implementation of teaching objectives,curriculum integration and implementation of core literacy.This research will carry out the Ub D model based on the high school mathematics unit teaching,based on the unit design,pay attention to the learning process,develop the core motivation,study new courses and new textbooks,try to change ideas,explore effective teaching strategies under the "Double New",and achieve "understanding mathematics,understanding students,and understanding teaching".In this study,literature method,teaching experiment research method,interview method and statistical analysis method are adopted.Firstly,the research status of unit teaching and Ub D model at home and abroad was sorted out and compared.Secondly,we organically combine the two modes to form a new teaching design operation process suitable for the teaching mode.Thirdly,according to the logical order of the teaching materials,the teaching design is divided into courses.Finally,the curriculum design is applied to teaching practice,and the independent sample T-test analysis is made on the results of the two after-school tests of the experimental class and the control class.Comparing the observation data of experimental class and control class,it shows that this teaching mode can improve students' enthusiasm to participate in class,effectively activate the classroom atmosphere,and significantly improve students' academic performance.Through teacher interview,it shows that this teaching mode can help teachers shift to "unit vision" and "performance evaluation" teaching.The conclusions of this study are as follows: First,the teaching of senior high school mathematics unit based on Ub D model is conducive to the cultivation of core literacy of mathematics discipline.Secondly,the teaching design of high school mathematics unit based on Ub D model is effective in improving students' learning performance.Thirdly,the teaching design of high school mathematics unit based on Ub D mode is beneficial to the change of teachers' teaching concept.
