在新课程改革的背景下,培养学生的创新意识和探究能力,越来越受到人们的关注,探究是数学的生命线,而探究的前提则是需要提供开放的思维空间,为了激发学生的探究能力,培养学生的思维能力,我设计了一堂开放式的探索课。一、教学设计的背景与思路圆锥曲线是高中数学的重点内容,是近几年高考的热点,一方面,圆锥曲线的多样性及解题方法的灵活性,为学生多层次、多角度、多方位探索问题提供了开阔的思维空间;另一方面,直线与
In the context of the new curriculum reform, cultivating students’ innovative awareness and inquiry capabilities has attracted more and more attention. Inquiry is the lifeline of mathematics, and the premise of inquiry is the need to provide open thinking space in order to stimulate students’ inquiry ability. To cultivate students’ thinking ability, I designed an open exploration class. First, the background and ideas of teaching design Conical curve is the focus of high school mathematics, college entrance examination in recent years is a hot spot, on the one hand, the diversity of the conic section and the flexibility of the problem-solving method for the students multi-level, multi-angle, and more The orientation exploration problem provides open thinking space; on the other hand, straight lines and
