Action Research On The Teaching Design Of Primary School Mathematics Unit Based On UbD Mode

Mathematics Curriculum Standards for Compulsory Education(2022 edition)emphasizes the overall grasp of teaching content,pays attention to the cultivation of students’ core qualities,and advocates the concept of unit teaching design.Ub D mode takes the preset teaching objectives as the starting point,forms the teaching design according to the learning performance required by the teaching objectives,focuses on deepening the understanding of students to knowledge,and its main idea provides a new path for the unit teaching design.This paper focuses on action research,supplemented by literature,interview and testing.The main research work includes five parts.The first part is to read literature and sort out the research results related to unit instructional design and Ub D model.The second part is to draw up the action research plan and determine the research object;The third part carries out action research.Firstly,through interviews with front-line mathematics teachers and sixth grade students who practice in primary schools,the existing problems in the teaching design of primary school mathematics units are clarified.By referring to the main ideas of Ub D mode,the existing problems are improved to form a preliminary improvement plan.Secondly,the improved scheme is applied to the specific mathematical unit teaching design,and two rounds of action research are carried out to improve the unit teaching design scheme.The fourth part is the summary and reflection,through the combination of the experience gained in the process of action,summed up the basic process of elementary school mathematics unit teaching design based on Ub D mode,and obtained the corresponding implementation strategy;The fifth part is the summary and prospect of the whole research.By combining theory and practice,this study applies the constructed elementary school mathematics unit teaching design scheme to the first-line practical teaching.Through continuous feedback and improvement,it is expected to provide a reference for the first-line elementary school mathematics teachers’ experience of unit teaching design.
