【实验目标】新课标提倡学生自主学习,努力倡导“自主、合作、探究”的学习方式。而我们的教学往往是教师高高在上、一言堂,苦口婆心而收效甚微。所以,我也想改变改变教学策略,在教一个新知识点之前,教师有意识地提出教学任务,通过学生自主探究,以求自主发现知识,获取知识,不仅可以让学生获取学习成功的体验,还可以增强他们学好数学的信心。【实验对象】所授六年级全班学生。【实验内容】 【Objectives】 The new curriculum promotes students to learn independently and strives to advocate the learning style of “autonomy, cooperation and inquiry”. And our teaching is often a high teacher, a word, well-meaning and with little success. Therefore, I also want to change the teaching strategy to change. Before teaching a new knowledge point, teachers consciously put forward their teaching tasks. Through their own exploration, students can discover and acquire knowledge independently. This not only enables students to acquire a learning experience, Can enhance their confidence in learning mathematics. [Experimental subjects] Sixth grade class students. 【Experiment content】
