Research On Unit Instructional Design Based On Unitary Quadratic Equation Of Core Literacy

Under the background of "Subject literacy entering the classroom" being advocated and combined with the characteristics of integrity and systematicness of mathematics knowledge itself,it has become a starting point to carry out large unit teaching design extensively,and unit teaching research based on core literacy has become a hot topic.The quadratic equation is an effective model to depict the quantitative relationship in the real world,an important tool for students to establish the relationship between mathematics and life,and an important content of junior middle school students' mathematics learning.Therefore,the unit teaching research based on core literacy has certain practical significance and reference value,so the research theme of this paper is established.Based on the research background and teaching practice,the following questions are raised :(1)what are the difficulties in developing unit teaching at present?(2)What efforts should teachers make to implement the unit teaching of "unitary quadratic equation" ?(3)Based on the core literacy,what are the basic strategies for teaching unitary quadratic equation units?(4)In the teaching of quadratic equations with one variable,what specific learning content corresponds to what core qualities?In order to solve the above confusion,the research methods of this paper are(1)literature method,(2)interview method,(3)comparative analysis method.I consulted relevant literature and books with the help of CNKI,university electronic library and other platforms to accumulate theoretical basis.Some junior middle school mathematics teachers in three schools were interviewed to preliminarily understand the practical difficulties and efforts needed in unit teaching,as well as what learning contents are used as the carrier and what learning activities are used to achieve core literacy.This paper compares and analyzes the teaching treatment in the part of quadratic equation of one variable in three editions of textbooks,and establishes teaching objectives and teaching plans.Through interviews and teaching experience,this paper acquires some difficulties and reasons in implementing unit teaching at present stage,and tries to put forward corresponding strategies and suggestions on the problems found.Based on the collation of materials and the comparison of teaching materials,this paper puts forward the basic strategies of unitary quadratic equation unit teaching based on core literacy,and makes corresponding analysis of unitary quadratic equation unit teaching based on curriculum standards.Finally,based on the above research and analysis and reflection on teaching practice,a specific teaching case is given to illustrate its operation process.
