Teaching Research On Large Units Of Primary School Mathematics Under The Concept Of Deep Learning

In the new century,with the rapid development of politics,economy,culture,and technology,the future society has become increasingly uncertain and unpredictable.How to adapt the current children to the future world is a huge challenge faced by all countries in the world.Curriculum reform,as the core area of education reform,has increasingly become the main battlefield for countries to implement talent competition strategies.In 2014,my country launched a comprehensive and deepening curriculum reform,and the "deep learning" teaching improvement project came into being.To promote the development of deep learning,large unit teaching is the most effective way.At the same time,in order to break the fragmentation and dispersal of student knowledge in class-time teaching,and promote the transfer of student knowledge,domestic experts call on front-line teachers to build the overall teaching content and implement large unit teaching under the guidance of big concepts and concepts.Promote the structuring of students' cognition.Based on this,the author proposes a large unit teaching research under the concept of deep learning,exploring the integration of large unit teaching and deep learning,and exploring large unit teaching strategies that promote students' deep learning.This research first explains the reasons and significance of the topic selection.Through deep learning,large unit teaching domestic and foreign research status review,and deep learning concept of large unit teaching research status summary,clarified the connotation,characteristics and characteristics of deep learning and large unit teaching.The relationship between the two theoretically demonstrates the feasibility of this research,and then establishes the research ideas and research methods of this research.After that,through student questionnaires and teacher interviews to understand the current situation of student learning and teachers' views and suggestions on large unit teaching.The survey results show that most students already have the characteristics of deep learning,and have the consciousness of actively participating in learning,critical and questioning,knowledge construction,problem solving,knowledge transfer,and summary reflection.Among them,students have strong problem-solving skills,have a certain knowledge construction ability,can use intuitive graphics to help them understand knowledge,most students can actively participate in the classroom,discuss problems,and speak their own ideas.However,there are still some problems: the overall level of students' deep learning is not high,teachers' understanding of deep learning is not comprehensive enough,and teachers lack the experience of constructing large unit teaching from a high point of view.The above results demonstrate the feasibility of this research from a realistic perspective.Based on the survey results,the author divides the large-unit teaching into three parts: "preparation phase","design and implementation phase",and "reflection and evaluation phase".In the "preparation phase",two aspects of textbook interpretation and student interpretation are proposed.Large-unit teaching strategy;"Design and Implementation Phase" puts forward a large-unit teaching strategy focusing on overall control and selected activities;"Reflection and Evaluation Phase" proposes a large-scale teaching strategy that focuses on formative evaluation and encourages students to reflect in multiple ways.Unit teaching strategy.Finally,in accordance with the proposed strategy,based on the units of “Two Digits Multiplied by Two Digits” in the second volume of Beijing Normal University Edition and “Three Digits by Two Digits” in the first volume of fourth grade,designed a large unit teaching of "Multiple Digits by Multiple Digits".
