Transformed Thinking In Primary Mathematics "Space And Shape"

This paper focuses on the research transmute the thought-form and in elementary school mathematics "space and shape" teaching materials and the teaching of advanced mathematics. From the first mathematical thought, transformation ideology, space and shape of the concept of the widespread contact with objective things, eternal development and contradictory unity of opposites in certain conditions co-transformation for transformation ideology philosophy foundation, theory of maintaining assimilation to transmute the thought-form of psychological foundation, and points out that the transformation ideology in elementary school mathematics "space and shape" the important significance. Secondly, this research mainly the systematical investigation of the all 12 compulsory education trial mathematics course books of elementary school(JEP) to explore transformation ideology in elementary school mathematics "space and shape" the embodiment and application, found penetration transmute the thought-form of teaching content, teaching material of each book academically but not desultorily, mainly on the plane figure with three-dimensional graph conversion, triangle falling and polygon area formulas derivation and three-dimensional graphics surface area (or lateral area) and volume equation of, and puts forward some proposals to the teaching material. On the basis of teaching practice with personal experience, according to the new curriculum standard request, make students understand and experience transformation ideology, combined with concrete examples put forward in elementary school mathematics teaching "space and shape" teaching how to efficiently apply:devotedly mining; Selection method; Positive applications; Strengthen training.
