“以学生为本”是数学课堂教学的基本原则,培养学生终身学习能力是课堂教学的方向,让学生掌握研究问题的方法形成数学问题意识是数学课堂教学的最高境界.本文借建构主义学习理论“支架式”教学指导下的苏教版高中数学(必修4)§1.3.3函数y=Asin(ωx+φ)的图象第二课时课例来体现在高中数学 “Student-centered” is the basic principle of mathematics classroom teaching. Cultivating students’ life-long learning ability is the direction of classroom teaching. It is the highest realm of mathematics classroom teaching that the students master the method of research problems. This paper uses constructivism.
