随着课程改革的不断深入,在培养学生创新能力与讲授理论知识有效结合的新背景下,如果我们一线教师还不与时俱进,还依赖传统的教学手段及一张嘴、一本书、一支粉笔,就很难达到小学数学三位一体的教学目的。笔者认为,教师必须对新教材有效理解,深入挖掘与探究,才能让数学课堂充满活力。 With the continuous deepening of the curriculum reform, under the new background of cultivating students’ ability to innovate effectively and lecturing theoretical knowledge, if our front-line teachers still do not advance with the times, they also rely on the traditional teaching methods and a mouth, a book, a book Chalk, it is difficult to achieve the primary school mathematics trinity teaching purposes. The author believes that teachers must be effective understanding of new textbooks, in-depth mining and exploration, in order to make mathematics classroom full of vitality.
