Research On Teaching Design Of Primary Mathematics "Trapezoidal Area" Based On The Core Literacy Of Mathematics

The mathematics core literacy has become a hot word in current Chinese mathematics education,and it has gradually become the key basis for the reform of mathematics classroom teaching,the reform of examination and evaluation systems,and the measurement of mathematics teaching goals.It is the long-term goal of the next step in the design,development,and practice of mathematics courses.Under the current background of core mathematics literacy,in order to implement the requirements of the new curriculum standards,understanding of core mathematics literacy and how to cultivate students’ core mathematics literacy in primary school mathematics teaching need to be considered and explored as front-line teachers and education researcher‘s important question.Mathematics teaching design provides a scientific action program for all subsequent mathematics teaching activities.It is particularly important to incorporate the core literacy of mathematics into mathematical teaching design.However,because the meaning of mathematical core literacy is still relatively abstract and general,the current methods and methods for cultivating students’ mathematical literacy are still being explored.It is still difficult to grasp how to optimize mathematical teaching design based on mathematical core literacy.One question,this research is based on the core literacy of mathematics,and researches the teaching design of the "trapezoidal area" of primary school mathematics.It really makes the meaning of core literacy of mathematics concrete and operable in teaching design,which is beneficial to broaden mathematics.The teaching perspective has a positive impact on the rich research results of trapezoidal area teaching cases and the design of trapezoidal area teaching.By consulting a large amount of literature,based on the theoretical research of core mathematical literacy,the basic framework of instructional design is constructed,and the students are analyzed in advance.According to the students ’existing experience and level,starting from the cultivation of students’ core mathematics literacy,the teaching design of "trapezoidal area" was carried out from four aspects: teaching goal design,teaching content design,teaching process design,and teaching evaluation design.The design is applied to teaching and the implementation results are analyzed and feedback,which is different from the traditional teaching design in the past.The "trapezoidal area" teaching design based on the core literacy of mathematics effectively cultivates students’ mathematical reasoning,mathematical communication,spatial concepts,Mathematical core literacy such as application of mathematics and innovation.Finally,after teaching reflection,three suggestions were put forward: pay attention to students’ expressions and develop students’ mathematical logical thinking;implement stepwise operation to cultivate students’ core mathematical literacy;attach importance to classroom generation and improve students’ mathematical creative enthusiasm.
