Research On The Unit Integrated Teaching Design Of Primary School Mathematics

The implementation of unit integrated teaching is not only the development trend of the current education and teaching reform,but also an important teaching mode to highlight the overall relevance of mathematical knowledge.It is helpful to promote teachers’ professional development,enrich education and teaching theory,cultivate students’ mathematical literacy,and promote the teaching and research of mathematics.At present,there are some problems in the content arrangement of primary school mathematics textbooks,such as the fragmentation and fragmentation of some contents,the contradiction between the arrangement of textbooks and students’ learning basis and cognitive law,the contradiction between teachers’ "class hour" design and the "overall" structure of mathematics knowledge.The overall teaching situation of primary school mathematics unit is not optimistic.In this paper,literature survey,case analysis,questionnaire survey and other research methods are used to clarify the theoretical basis of the overall unit teaching design by consulting the relevant literature of the overall unit teaching.On this basis,taking some typical units of primary school mathematics published by people’s education press as examples,the overall instructional design of primary school mathematics units is studied,and the following overall instructional design process is formed:(1)through the investigation of students’ learning situation and the unit interpretation of teaching materials,the matching problem between students’ cognitive sequence and knowledge sequence of teaching materials is diagnosed,and the research problems and research direction are determined.(2)Based on the problem,the research ideas of the overall teaching design of the unit are determined by the teachers’ team cooperation and collective discussion.(3)On the basis of the analysis of students’ learning situation and teaching materials,this paper puts forward a preliminary idea of the overall design of the unit according to the standard of unit design.(4)Under the guidance of the preliminary idea,the key lesson in the whole unit teaching is taken as the starting point to carry out teaching design,put it into classroom practice,constantly reflect and adjust,verify the rationality of the preliminary idea,and then put forward the overall design framework of unit teaching.On the basis of teaching practice and case study,this paper summarizes the following design strategies for the overall teaching of primary school mathematics unit:(1)the horizontal structure is related to construct a reasonable teaching sequence.By using the overall overview map,we can clear the context of mathematics knowledge;strengthen the method to realize the transfer learning of mathematics;contrast teaching to highlight the essence of concept learning;multi-directional correlation to realize the overall penetration of knowledge.(2)Longitudinal extension and expansion,through the knowledge before and after relevance.In order to get through the frontier and follow-up of knowledge,we should grasp the order and follow the knowledge sequence of teaching materials,and advance step by step.(3)Based on the students’ learning situation,grasp the structure and establish a reasonable order.Based on the learning situation,adjust the key and difficult points of teaching;pay attention to the sequence,order students’ cognitive construction;structural learning,improve students’ learning quality.
