“解决实际问题”是小学数学教学内容的重要组成部分,也是小学数学教学的重点,学生学习的难点。不少教师因为缺乏有效的教学策略,导致“解决实际问题”的教学陷入困境。要突破这一困境,应该注重学生主体地位,发展学生元认知能力;重视数量关系分析,构建基本数学模型;巧抓基本解题训练,积累解决问题经验。具体而言,应该发展学生的问题意识,提高学生的思维水平,培养学生的反思能力;数形结合,再现原题,语言表述,理清思路;摆脱类型化的教学,精选灵活的练习题。
“To solve practical problems ” is an important part of the primary school mathematics teaching content, but also the focus of primary mathematics teaching, student learning difficulties. Many teachers are in a dilemma because of the lack of effective teaching strategies that lead to the teaching of “solving practical problems.” To break through this predicament, we should pay attention to the dominant position of students and develop students’ metacognitive ability; attach importance to the quantitative relationship analysis and construct the basic mathematical model; grasp the basic problem-solving training skillfully and accumulate experience in problem solving. Specifically speaking, we should develop students’ awareness of the problems, raise the students’ thinking level and cultivate the students’ ability of reflection. Combine the figures with the original words and expressions and clarify their thinking; get rid of the type teaching and select the flexible exercises .
