抽象的数学知识须运用直观教学方式
发布时间：2018-11-24 20:44
【摘要】：正抽象是从众多的事物中抽取出共同的、本质性的特征,而舍弃其非本质的特征。直观是通过对客观事物的直接接触而获得的感性认识。二者处在认知活动的不同层次,甚至是对立的。在小学阶段,学生的思维处在具象向抽象过渡的阶段,数学教学如果停留在直观的层面,就没有达成目标,而一味地抽
[Abstract]:Positive abstraction is the extraction of common, essential features from many things, and the abandonment of their non-essential features. Intuition is a perceptual understanding obtained through direct contact with objective things. They are at different levels of cognitive activity, even opposite. In the primary school stage, the students' thinking is in the stage of transition from concrete to abstract. If mathematics teaching stays at the level of intuition, it will not achieve the goal, but blindly draw.
