Research On Teaching Design Based On Mathematical Core Literacy

With the further development of basic education curriculum reform,our country putted forward the fundamental task of education,which is to “build morality and cultivate people”.In order to implement this fundamental task,the core literacy has been proposed.As an important basic subject,the core literacy of mathematics has attracted much attention.It is not only the concentrated reflection of the objectives of mathematics curriculum,but also the basic literacy that everyone should possess in modern society.How to implement the core literacy of mathematics through classroom teaching has become an issue of great concern in today's society and mathematics education circles.Derivative knowledge is rich in connotation and has a very high educational value,which is a good carrier for cultivating students' mathematical core literacy.However,the teaching of derivative has not played its due role in actual teaching,which is closely related to the teaching of teachers.Teaching design is the blueprint of classroom teaching and an important basis for achieving the curriculum objectives.The quality of teaching design affects the quality of classroom teaching directly.Furthermore,after consulting extensive literature,it is found that there is less research on the integration of core literacy into mathematics teaching design of high school combining theory and practice.Therefore,this study takes the derivative in high school as an example to research the teaching design based on the core literacy of mathematics,and discusses the design principles,design strategies and general framework of the mathematics teaching design of high school oriented by mathematical core literacy.Firstly,this study introduces the research results of mathematical core literacy at home and abroad and the teaching design based on it and introduces the current state of teaching research of derivative in high school.This study finds the theoretical support,and defines related concepts at the same time.Secondly,with the aim of the implementation of core literacy,based on the constructional learning theory and the mathematics education theory ofH.Freudenthal,the principles and strategies of teaching design based on the core literacy of mathematics are proposed.Then,taking “derivative and its application” as an example,the teaching design case is given,which adopts the mode of “designing the time-based teaching design after the overall analysis of the unit” and it is based on the requirements of developing students' mathematical core literacy.Finally,the teaching design is implemented in a class.By observing the classroom recording,the teacher's teaching and the student's learning are evaluated from the four aspects which can reflect the mathematical core literacy.At the same time,the feedback information is obtained by collecting and correcting the students' target detection exercises and returning surveys.I rethink my teaching combining with the evaluation results and feedback information,and the teaching design is further modified.From the implementation of the teaching design,it can be concluded that the teaching design based on the mathematical core literacy is better.Finally,the basic framework of teaching design based on mathematical core literacy is formed preliminarily in this study.
