Research On Unit Teaching Design Based On The Cultivation Of Mathematics Core Literac

The "General High School Mathematics Curriculum Standards（2017 Edition 2020Revision）" pointed out that the overall grasp of teaching can promote the development of the core literacy of mathematics,The unit teaching design has the function of planning the teaching content as a whole,and is a method and approach of mathematics teaching design advocated under the new concept.On the basis of literature research,choose "ADDIE" as the theoretical basis for the teaching research of "theme-unit",and taking "the equation of a straight line and a circle" as an example,the core literacy of mathematics and the elements of unit teaching contained in the content of the unit are analyzed,the unit teaching design and practice are completed,and test the practical effect.The research shows that:（1）Unit teaching based on the core literacy of mathematics can promote the development of students’ core literacy.（2）The unit teaching based on the core literacy of mathematics can improve the pass rate of students in the class,and at the same time,the improvement of the grades of qualified students is more significant.To implement the unit teaching design based on the cultivation of mathematics core literacy,the following points should be done in teaching:（1）Strengthen the professional quality of teachers,and pay attention to the comprehensiveness and integrity of teaching;（2）Pay attention to the formulation of unit teaching goals and promote The development of the core literacy of mathematics;（3）Pay attention to the choice of teaching strategies,which is conducive to the development of the core literacy of mathematics.
