随着课堂教学改革的不断深入,传统的课堂教学模式已无法适应小学数学课堂教学改革的需要。只有重视课堂教学模式的研究,才能充分揭示课堂教学的一般程序和普遍规律;只有优化课堂教学模式,才能达到大面积提高数学教学质量的目的。2013年10月21~23日,有幸参加全国第十一届深化小学数学教学改革观摩交流会,其中广东省骆奇老师执教的“公倍数与最小公倍数——尾巴重新接回的奥秘”一课,以巧妙的设计、新奇的活动和有效的建构让我们见识到了另一种教学模式,给我留下深刻的印象,听完颇有感触。一、设计巧妙,立题新《数学课程标准》指出:“数学教学必须从学生熟悉的生活、感兴趣的事物中提供观察和操作的机会,使学生体会到数学 With the continuous deepening of classroom teaching reform, the traditional classroom teaching mode can not meet the needs of the reform of primary school mathematics classroom teaching. Only by focusing on the research of classroom teaching mode can we fully reveal the general procedures and universal laws of classroom teaching. Only by optimizing the classroom teaching mode can we achieve the purpose of improving the quality of mathematics teaching on a large scale. From October 21 to October 23, 2013, I was fortunate enough to attend the 11th National Deepening Primary School Mathematics Teaching Reform Observatory and Exchange Seminar, in which Professor Luo Qiao from Guangdong Province coached ”the common multiple and the least common multiple - the mystery of tail recovery“ Lessons, with clever design, novel activities and effective construction so that we have seen another teaching mode, left a deep impression on me, after listening quite touching. First, the design clever, new legislation, ”Mathematics Curriculum Standard“ pointed out: ”Mathematics teaching must be familiar with students from life, interested in things to provide observation and operation of opportunities for students to experience mathematics
