预习是小学数学教学的一个重要环节,也是学生学习的起点。根据课改理念,我校掀起“先学后教有效教学”的教学模式,笔者积极尝试并构建了“习、展、评、练”四步法,其中的“习”就是预习,让学生进行充分的课前理解,课前消化,以促进课堂上的有效吸收。现从自己的实践入手,谈谈有效预习的几点做法。一、激发兴趣,建立预习意识数学教学中,要让学生调动起预习热情,建立积极的预习意识,这需要一个循序 Preview is an important part of primary school mathematics teaching, but also the starting point for student learning. According to the concept of curriculum reform, our school set off a teaching mode of “effective instruction after teaching first”, and the author actively tried and constructed a four-step “learning, exhibition, assessment and training” Is a preview, allowing students to fully understand before class, pre-class digestion, in order to promote effective absorption in the classroom. Starting from their own practice, talk about effective preparation for a few practices. First, to stimulate interest in establishing a pre-learning awareness In mathematics teaching, to enable students to mobilize enthusiasm for the preview, the establishment of a positive preview consciousness, which requires a sequence
