摘要
教育数学通过再创造改造数学,经历数学化的过程,还原数学的本质,是具有教育形态的数学。基于教育数学思想,下放三角,用面积方法建立三角学,用三角推导几何,对数学课程进行结构性改革,形成了“一线串通”的初等数学新体系,蕴含着回归原点、返璞归真、形成联系、深度理解、感受数学、领悟精神、抽象概括、演绎推理的逻辑意义,数学教材开发要还原数学真正的面貌,满足个性化学习需要,建立新的数学教材标准。
Educational mathematics is a kind of mathematics with educational form,through recreation and transformation of mathematics,experiencing the process of mathematicalization and restoring the essence of mathematics.On the basis of the educational mathematics thought,the triangle is devolved,the triangle is established by the area method,the geometry is deduced by the triangle,and the mathematics curriculum is reformed structurally.A new system of elementary mathematics in line collusion is formed,which contains the logical meanings of returning to the origin,returning to reality,forming connections,deep understanding,feeling mathematics,understanding spirit,abstract generalization and deductive reasoning.The development of mathematics textbooks should restore the true face of mathematics,meet the needs of individualized learning,and establish new standards of mathematics textbooks.
