一、创设情境,激发兴趣前苏联教育家苏霍姆林斯基指出:“没有欢欣鼓舞的心情,没有学习兴趣,学习就会成为学生的负担”而教学情景的创设尤为重要,让学生在情境中学,能给枯燥的学习生活带来活力。如我在教学《直角的初步认识》一课时,就是以《小马过河》的故事情节贯穿整个教学过程,上课一开始,我先用多媒体课件展示动画片《小马过河》。小马去磨房的路上遇到一条河不知深浅。 First, the creation of the situation, to stimulate interest Former Soviet Union educator Su Homlinski pointed out: “no joy, no interest in learning, learning will become a burden on students ” and the creation of teaching situations is particularly important for students In situational high school, can bring vitality to the boring study life. As I was teaching “A Preliminary Understanding of Right Angle”, I started with the story of a “colt crossing the river”. From the very beginning of the class, I started with a multimedia courseware to show the animated “Pony crossing the river.” Pony to go to the mill on the road encountered a river I do not know the depth.
