“良好的开端是成功的一半。”的确,有效导入不仅能够激发学生的学习热情,提高学生的课堂参与度,而且也是影响高效数学课堂顺利实现的重要因素。所以,为了激发学生的学习欲望,也为了构建出以学生的发展为中心的数学课堂,在教学时,一线数学教师要结合教材内容来选择和应用多种导入活动,以活跃课堂气氛,提高学生的学习质量,同时,也能确保数学课程价值最大化实现。 “Good start is half the success.” Indeed, effective introduction not only inspires students ’enthusiasm for learning and improves students’ classroom participation, but also is an important factor that influences the smooth implementation of an efficient math class. Therefore, in order to arouse students ’learning desires, in order to construct a mathematics classroom focusing on the development of students, first-line mathematics teachers should select and apply various kinds of import activities in combination with the contents of the teaching materials in order to activate classroom atmosphere and enhance students’ The quality of learning, but also to ensure that the value of mathematics curriculum to achieve maximum.
