在高效课堂教学活动中,我有幸聆听了“平行四边形的性质”一课,教者通过动手操作,让学生在自主的思维活动中建构新的认知知识,既训练了学生的动手操作能力,又训练了学生思维的灵活性,培养了学生的创新能力。现撷取几个教学片段,与同仁们共享。片段一借助生活,巧妙揭题师:同学们,你们留意观察过阳光透过长方形窗口投在地面上的影子是什么形状吗?生:矩形、四边形、平行四边形……师:太阳光属于平行光,窗口投
In the efficient classroom teaching activities, I was fortunate enough to listen to the lesson “The Nature of Parallelograms”. Through the hands-on teaching, students can construct new cognitive knowledge in autonomous thinking activities, which not only train students’ hands-on activities Ability, but also trained the flexibility of student thinking, cultivate the students’ ability to innovate. Now pick up a few teaching clips, and colleagues to share. Fragment one with life, clever Jie Jie teacher: students, you observe the sun through the rectangular window on the ground shadow is what shape? Health: Rectangle, quadrilateral, parallelogram ... ... Division: The sun is parallel to the light , Window cast
