《全日制义务教育数学课程标准(修定稿)》中强调指出:“要充分发挥数学在培养人的科学推理和创新思维方面的功能。”强调了“数学课程能使学生掌握必备的基础知识和基本技能,培养学生的抽象思维和推理能力,培养学生的创新意识和实践能力”。依据“课标”新理念,笔者认为数学课堂在训练学生思维发展的基础上,要注重培养学生的推理能力。一、要注重直接推理直接推理就是从已知条件出发,直接推出结论。小学数学课堂教学要依据儿童简单的知识基础和儿童身心发展的特点,多运用直接推理,培养儿童直接推理的 The Full-Time Compulsory Education Mathematics Curriculum Standard (Revised Edition) emphasizes that “we should give full play to the function of mathematics in developing scientific reasoning and innovative thinking of human beings.” “Emphasizing that mathematics curricula enable students to master the necessary Basic knowledge and basic skills, develop students ’abstract thinking and reasoning ability, cultivate students’ innovative awareness and practical ability ”. Based on the new concept of “standard”, the author thinks that mathematics classroom should focus on cultivating students ’reasoning ability on the basis of training students’ thinking development. First, we must focus on direct reasoning Direct reasoning is from the known conditions, the direct conclusion.
