Research On Unit Instructional Design Based On The Concept Of Educational Mathematics

According to the Outline of the National Plan for Medium-term and Long-term Education Reform and Development,more attention should be paid to the cultivation of students ’ ability in teaching,so as to make the students’ knowledge system more perfect and their after-school practice more abundant.The Mathematics Curriculum Standards for Compulsory Education(2022 edition)points out that it is necessary to change the teaching design that pays too much attention to the class hour,promote the overall teaching design of units,reflect the internal logical relationship between mathematical knowledge,and the correlation between learning content and the performance of core literacy.However,at present,most teachers still insist on traditional teaching by class hours,which makes unit teaching a mere formality,lack of systematic design and application,and it is difficult to take the advantages of unit teaching.As an important prerequisite for unit teaching development,the research of unit teaching design is very important.The purpose of educational mathematics is to reorganize knowledge for mathematics education,so as to make it easy for students to learn mathematics.At the same time,educational mathematics also emphasizes the systematization and integrity of knowledge,which coincides with the idea of unit teaching.Based on the above facts,this paper takes the unit of "quadratic equation with one unknown" as an example to study the unit instructional design based on the educational mathematics concept,which mainly includes the following three research questions:(1)how to carry out the unit teaching design based on the concept of educational mathematics?(2)What are the characteristics of unit teaching design based on educational mathematics concept?(3)What is the unit teaching design strategy based on the educational mathematics concept?This study integrated theory and practice,using literature analysis,comparative analysis,teaching experiments and interviews,follow the following ideas: First,through the analysis of the relevant literature,to define the concept of this study,to determine the content of the study,to develop the plan for the study.Secondly,analyze the theory of educational mathematics and unit teaching,summarize the operation process of unit teaching design based on the educational mathematics concept.Once more,based on the teaching-based design process,instructional design of unit of quadratic equation with one unknown,and after the teaching implementation,through learning experience,student interviews,unit tests,classroom observation,peer assistance and teaching reflection,on this basis,modify the teaching design.Finally,the research conclusion and reflection of this paper are drawn.The main result of the research is to summarize the operation steps,characteristics and strategies of the unit instructional design based on the concept of educational mathematics,and form the case of unit instructional design based on the concept of educational mathematics.The main conclusion of the research is that the unit teaching design based on the educational mathematics concept has the characteristics of integrity,reconstruction,development,situation and Student-oriented.Unit teaching design strategies based on the concept of educational mathematics:(1)attaching importance to theoretical learning and enriching teaching methods,(2)conducting unit analysis and promoting overall grasp,(3)integrating teaching content and promoting multi-element cognition,(4)following core literacy and formulating teaching objectives,(5)optimize unit planning based on teaching objectives,(6)emphasizing dynamic design and improving teaching quality,(7)promoting multiple evaluation and promoting effective teaching.
