学习数学是小学生在数学认知领域有关知识、技能、能力达到预定目标的相对持久的过程。学生必须通过练习这种学习方式来获得知识、技能和能力。而要让练习发挥最大的教学效能,教师应该在练习设计方面别具匠心地一番功夫,通过精心选择与设计,把练习从传统的形式单一、机械重复变成内涵丰富、形式多样,以促进学生对数学知识的有效性生成。在教学中教师除了要在课内做到知识渗透,还应由课内延伸到课外,设计出一些别有新意的数学练习,开阔学生的知识视野,引领学生在自己探求知识的过程中培养创新意识和实践能力。
Learning mathematics is a relatively long-lasting process for pupils to achieve their intended goals in knowledge, skills and abilities in the field of mathematical cognition. Students must acquire knowledge, skills and abilities by practicing this learning method. In order to maximize the effectiveness of teaching, teachers should make a meticulous effort to practice design. By carefully selecting and designing exercises, the practice will be changed from a single form of traditional practice to a repetition of mechanical repetition with rich contents and various forms to promote students’ The validity of mathematical knowledge is generated. In addition to teaching teachers in the class to achieve knowledge infiltration, but also by the class extended to extra-curricular, designed to introduce some new mathematical exercises, broaden students’ horizons of knowledge, to lead students in their pursuit of knowledge in the process of training and innovation Consciousness and practical ability.
