Unit Teaching Research Based On The "function" Of The Core Literacy Of Mathematics

"General Mathematics Curriculum Standards for High Schools(2017 Edition)" states that teaching should be centered on the subject and guided by the theme,gradually improve the comprehensive quality of students,and vigorously develop core literacy.Based on the literature research,based on Professor Zhong Qiquan’s "ADDIE" model as a theoretical basis,the general steps of unit teaching are designed,and unit teaching research on "function concepts and properties" based on the core literacy of mathematics is carried out.The unit teaching design and practice of "function concepts and properties" were completed,and the data analysis of unit teaching effects was performed.Studies show that:(1)Two classes with similar levels in the pre-test,after a period of unit teaching and class teaching,respectively,there is a significant difference in the core literacy of mathematics subjects between the experimental class and the control class,and unit teaching The experimental class students have higher core literacy in mathematics.(2)Unit teaching is more effective for improving the performance of low-group students,and it is more conducive to the cultivation of core literacy in mathematics for low-group students.When designing unit teaching,teachers should conduct a holistic analysis of the teaching content,focusing on the integrity of the teaching content;understand the existing knowledge base and cognitive characteristics of students,and carry out targeted unit teaching design;adopt teacher-led,student-oriented,The three main teaching methods of the main thinking line are to cultivate students ’holistic thinking and improve students’ core literacy in mathematics.
