Research On Teaching Strategy Of "Graphics And Geometry" In Primary School Mathematics Based On Deep Learning

With the rapid development of society and the continuous advancement of the new curriculum reform,learning has become the core competitiveness to adapt to the future social development.As an important guiding concept for comprehensively deepening curriculum reform and an important way for implementing core literacy,deep learning has become an inevitable choice for human beings to transform learning style and cope with social challenges.As one of the four major knowledge areas of primary school mathematics,"graphics and geometry" knowledge contains key core qualities such as sense of quantity,geometric intuition,spatial concept and reasoning consciousness.As an indispensable part of teaching design,teaching strategy has a direct impact on teachers’ teaching and students’ learning.How to optimize the teaching strategies in the field of "graphics and geometry" of primary school mathematics with the help of the concept of deep learning,effectively promote students’ deep learning and improve their core qualities has become an important subject of subject teaching research.The purpose of this study is to put forward the teaching strategy of "graphics and geometry" of primary school mathematics based on deep learning,and to design and implement cases,so as to verify the effectiveness and feasibility of the teaching strategy.It mainly uses literature method,observation method,questionnaire survey method,interview survey method,experiment method and other research methods.First,based on theoretical research,the concepts of deep learning and teaching strategies are defined to clarify the characteristics of deep learning.Secondly,taking the teachers and students of grade 4-6 in R Primary School in Xiamen,Fujian Province as the main research objects,the teaching and learning status of "graphics and geometry" in primary school mathematics was investigated through questionnaires,interviews,classroom observation and other methods.Then,based on the results of theoretical analysis and investigation of the current situation,centering on the three stages of the deep learning process model,the teaching strategy of "graphics and geometry" of primary school mathematics based on deep learning is proposed.In accordance with the proposed teaching strategy,"the area of a triangle" is taken as an example for practice verification.The comprehensive analysis shows that there are the following problems in the deep learning of "graphics and geometry" in primary school mathematics: students’ critical questioning ability has a large room for improvement,their understanding of knowledge is only superficial,and their awareness of reflection needs to be strengthened;Teachers’ understanding of deep learning is not comprehensive enough,and they lack the awareness to cultivate students’ critical questioning ability and reflective habit.Some teaching methods are more traditional.Combined with the theoretical basis and current situation investigation,this study puts forward the teaching strategy of "graphics and geometry" in primary school mathematics based on deep learning.The strategies in the preparation stage are as follows: interpret the textbook,dig deep into the geometric logic;Estimate the learning situation and determine the learning starting point;Design goals,pointing to higher order thinking;Create an environment that encourages bold questioning.The strategies of acquiring and deep processing knowledge are as follows: creating a real situation and cultivating the ability of transfer and application;Create cognitive conflict and promote the construction of geometric knowledge;Deepen understanding of geometry knowledge based on problem orientation;Task-driven learning,highly engaged in geometry class;Relying on multidimensional representation,it triggers students’ active learning.The teaching strategies in the evaluation stage are as follows: diversification of evaluation methods and comprehensive analysis of teaching effect;Infiltrate metacognitive strategies to guide students to reflect deeply.Through case practice,it is found that the "graphics and geometry" teaching strategy of primary school mathematics based on deep learning can improve students’ academic performance,thinking level,learning motivation,critical questioning,knowledge construction,learning interest,degree of involvement and reflective ability to varying degrees.It can be seen that the teaching strategy of "graphics and geometry" in primary school mathematics based on deep learning has certain reference value.The innovation of this study lies in the proposed teaching strategy of "graphics and geometry" in primary school mathematics based on deep learning,which helps front-line teachers implement teaching based on the overall situation and promotes the occurrence of deep learning for students.
