Research On The Teaching Strategies Of Cultivating Pupils' Space Concept

The concept of space is one of the ten core concepts put forward in the mathematics curriculum standard(2011 Edition).The concept of space is clearly stated in the mathematics curriculum standard(2011 Edition),"the geometry can be imagined from the shape of the real object,the shape of the real object can be imagined from the geometry,and the transformation between the geometry and its three views,unfolded drawings can be carried out.Can make three-dimensional model or draw figure according to the condition;can decompose the basic figure from the more complex figure,and can analyze the basic elements and their relations.Be able to describe the movement and change of physical objects or geometric figures;be able to describe the position relationship between objects in an appropriate way;be able to use figures to describe problems vividly and use intuition to think."Primary school is an important stage for children to form,develop and build their spatial imagination.However,in the actual teaching practice,we find that when students will feel difficult to learn,can not imagine the image of the object,the ability of spatial representation is poor,and the image can not be successfully established when the spatial combination is complex.Therefore,we focus on the three factors of the main body of learning-students,the carrier of knowledge-new curriculum materials and teaching implementers-teachers.We investigate and study the situation of space concept training of teachers and students in school,and analyze the problems faced by the primary school in developing space concept.The author hopes to explore the effective methods and Strategies of cultivating pupils' space concept from the aspects of teaching content,teaching implementation,influencing factors and the characteristics of children's space concept development,so as to provide useful reference for the development of students' space concept.Combined with the actual situation,this paper puts forward the teaching strategy of space concept in primary school: 1.Perception Teaching: pay attention to the use of visual and tactile senses and other senses to recognize geometry and form feature image;2.Operation teaching: guide students to perceive and understand the characteristics of geometry and develop space concept in practical operation;3.Variant Teaching: pay attention to the change of shape,position and size,Carry out dynamic variant teaching;4.Discrimination Teaching: pay attention to the difference and connection between knowledge,accurate differentiation,infiltration and transformation of ideas;5.Combination teaching: guide students to summarize and strengthen the systematization of knowledge,the combination of image and language,and the combination of number and shape.6.Using multimedia assisted teaching to deepen students' space concept.Among them,the low-level students pay more attention to the training strategy of space concept of Perception Teaching and operation teaching,while the middle-level and high-level students pay more attention to the training strategy of space concept of variable teaching,discrimination teaching and combination teaching.Finally,the paper analyzes four typical mathematics teaching examples of space concept,hoping to provide teaching reference for teachers.It is found that the concept of space is difficult to quantify.In the actual teaching process,cultivate students' concept of space and correctly evaluate the degree of development of students' concept of space is worth further study.
