| Mathematics Curriculum Standards for Compulsory Education(2022 Edition)clearly proposes to change the teaching design based on class hours,actively promote the overall teaching design of units,reflect the internal logical relationship between mathematics knowledge and the correlation between teaching content and the performance of core literacy,so as to promote students’ overall understanding and grasp of mathematics teaching content and gradually cultivate students’ core literacy.This article core to cultivate students’ mathematics accomplishment as the goal,by means of unit of whole teaching design,determine the main problems of the research: the core accomplishment of unit teaching design.Based on this main question,three sub-questions are put forward:(1)The current situation of junior high school students’ learning and the current situation of junior high school mathematics teachers about unit overall teaching design?(2)What are the basic principles and procedures of unit overall teaching design based on core literacy?(3)Based on the above survey results and the corresponding theoretical basis,the whole unit teaching design of "first order equations and equations" is given and applied in the actual classroom teaching to explore whether it has a positive role in promoting the development of students’ core mathematical literacy and students’ learning.To study the above three subproblems,research from the following several aspects: first,through the literature research to comb the core accomplishment,the overall unit teaching design related literature,analysis of the shortcomings of existing studies and puts forward the research question.Secondly,questionnaire is used to understand the learning status of junior high school students,and teacher interview is used to understand the cognition and implementation of frontline teachers on the unit overall instructional design.On this basis,basic principles of core literacy oriented unit overall instructional design are proposed,and general procedures of core literacy oriented unit overall instructional design are summarized by referring to existing research.Thirdly,based on the basic principles and general procedures,the whole unit of "first-order equation and equations" is analyzed,and the application of identifying one-order equation and one-order equation travel problem,engineering problem,solution of two-order one-order equations-addition,subtraction and elimination method,synthesis and practice-four teaching design cases of "one-order equation and equations" in the calendar are designed.And apply it to teaching practice.Fourthly,based on the empirical research,the author analyzes the effect of unit overall teaching,and reflects on the teaching design,so as to further improve the unit overall teaching design.Fifthly,it reflects on the research,gives some suggestions,analyzes the shortcomings of the research,and looks forward to the further research in the future. |
