数学是研究客观世界数量关系和空间形式的科学,它具有很强的概括性、抽象性和逻辑性。故数学教学,实质上是积极性思维活动的教学。普通中专的学生,其数学能力的抽象思维处在由经验型水平向理论型水平的急剧转化的时期,这意味着他们的思维逐渐脱离幼稚而趋向成熟。因此,数学教学活动必须适应学生思维发展飞跃时期的特点,进行积极
Mathematics is a science that studies the quantitative relations and spatial forms of the objective world. It has a strong generality, abstraction and logic. Therefore, mathematics teaching is essentially a teaching of positive thinking activities. The average thinking of ordinary secondary school students in mathematics abilities is from a period of experiential level to a theoretical stage, which means that their thinking gradually becomes immature and matures. Therefore, the teaching of mathematics must adapt to the characteristics of the leap of development of students' thinking and make positive
