Research On The Teaching Design Of Primary School Mathematics Large Unit Under The Guidance Of Core Accomplishment

With the comprehensive promotion of quality education through the new round of curriculum reform,quality,literacy,and core literacy have gradually become the focus of current education research.Classroom teaching,as the most basic teaching method,optimizing and integrating teaching design will inevitably affect the implementation effect of core literacy.In response to the phenomenon of fragmentation and fragmentation of knowledge in previous classroom instructional design,large unit instructional design has more effectively infiltrated core literacy with its integrated knowledge structure,real activity situations,and other characteristics.For primary school mathematics teaching,large unit teaching has important value and significance.It can provide a new way of thinking and learning methods for students’ learning,and also can comprehensively cultivate the core literacy of primary school students,improving teachers’ teaching ability and efficiency.The teaching design of the primary school mathematics large unit guided by the discipline core literacy focuses on the basic concepts of the primary school mathematics discipline.The purpose is to cultivate students’ essential qualities and key abilities regarding mathematical understanding and mathematical thinking methods,providing a new paradigm for primary school mathematics teaching.This study has formed a research thinking and writing framework by combing relevant literature on core literacy and large unit teaching design.Using literature research,interviews,and case analysis methods,this paper constructs research ideas for determining research topics,establishing theoretical foundations,constructing design ideas,conducting case design,summarizing,and reflecting.By clarifying the relevant content of core literacy and the main process of large unit teaching design,the cultivation of "sense of quantity" in primary school mathematics core literacy is integrated into large unit teaching design,and a multi-dimensional evaluation index system is constructed based on this.First of all,it is necessary to understand the theoretical basis of the teaching design of primary school mathematics large units under the guidance of discipline core literacy.Through combing the relevant literature,it is clarified that the teaching design of primary school mathematics big unit under the core literacy has the intrinsic value of optimizing mathematics teaching content,embodying the characteristics of mathematics discipline,and adjusting mathematics learning orientation,and has the characteristics of relevance,imbalance,growth and authenticity,and needs the overall unit teaching design Large unit teaching connects core literacy and classroom teaching,demonstrating the feasibility and advantages of combining the two,laying a theoretical foundation for this study.Secondly,provide practical support for the design of primary school mathematics large unit teaching guided by core competencies.By conducting interviews and surveys with teachers from multiple schools,it was found that most teachers have an understanding and recognition of the value of large unit teaching,and some teachers can consciously penetrate core competencies.However,it was also found that large unit teaching is not commonly used in daily teaching;On this basis,it was clarified that there are currently problems such as difficulty in distinguishing between overall goals and class hour goals,lack of systematic content integration,vague design ideas,single penetration of core competencies,and difficulties.It is believed that the main reasons are weak theoretical foundation of teachers,lack of practical experience,lack of school training resources,and lack of scientific indicator systems for the penetration and evaluation of core competencies,providing practical basis for subsequent case design,Make the teaching design of large units more targeted.Finally,based on literature review at the theoretical level and a survey of the current situation at the practical level,a specific approach for designing primary school mathematics large unit teaching is constructed.Guided by the principles of overall relevance,orderliness,and learning center,this paper proposes the analysis of unit teaching elements,refining unit core issues,establishing unit overall goals,resetting unit content sequences,determining unit core tasks,designing unit teaching strategies,and making specific case designs for this.This study mainly selected the "Measurement" unit from the first and second volumes of the second year edition of Beijing Normal University,as well as the "kilogram,gram,and ton" unit from the second volume of the third year edition,for the design of the large unit teaching.The themes,objectives,and links of the large unit teaching design were constructed from three aspects: extracting core problems,resetting content sequences,and designing teaching plans.
