A Study On Teaching Design Of Conic Curves Unit Under The Perspective Of Core Literacy In Mathematics

The promulgation of the General High School Mathematics Curriculum Standards(2017 Edition)marks that core literacy in mathematics has become an important engine to lead the reform of mathematics teaching and learning.Reconstructing the mathematics curriculum and teaching system based on the core literacy of mathematics is conducive to the fundamental task of establishing moral education.The core literacies in the curriculum standards clarify the abilities,character and values that students gradually develop in their learning,transcending the traditional teaching objectives and forcing classroom teaching towards unit teaching and teaching design towards unit instructional design.At present,unit teaching design has become an important way to implement the core literacy in mathematics.So,how to carry out the unit teaching design in the context of core literacy in mathematics? This is a topic worth studying in the field of teaching and learning.In view of this,the following study is conducted.First,the core concepts of this study are defined and the related literature on core literacy,conic curves,and unit instructional design are reviewed to provide support for the subsequent study.Second,questionnaires and interviews were used to understand the current situation of teachers’ unit instructional design at the cognitive and implementation levels,analyze the problems in the implementation process of teachers’ unit instructional design,analyze and find the causes,and provide a realistic basis for the unit instructional design in the context of core literacy in mathematics.Again,we outline the value implications of unit instructional design in the context of mathematical core literacy,analyze the value and significance of unit instructional design in the context of mathematical literacy,and explore the strategies of unit instructional design in the context of mathematical core literacy based on the current situation of teachers’ unit instructional design.Finally,based on the strategies and the existing research paths,we construct a theoretical path for unit instructional design in the context of core literacy in mathematics,and take the unit on conic curves as an example to carry out unit instructional design for conic curves in the context of core literacy in mathematics.Later,it was implemented in the classroom with good results,and further reflections were made to optimize the teaching design in order to provide reference for educational practitioners.Relevant results of this thesis:The path of unit teaching design in the context of core literacy in mathematics is constructed: selecting unit content,corresponding to core literacy;analyzing unit elements,providing a reasonable basis;setting learning objectives,leading teaching direction;dividing teaching stages,arranging unit teaching process;designing teaching time,implementing core literacy;creating evaluation tasks,reflecting and optimizing teaching design.
