众所周知,数学且有完备之美、对称之美、简洁之美、抽象之美,这是数学学科本身具有的美感。如果在课堂上,更多地留给学生感悟数学的时间和空间,让感悟的过程丰富多彩,这样的数学教学是美的,数学学习是美的,这样的数学课堂也是美的。一、创设情境,美在开始“学习的最好刺激,乃是对所学材料的兴趣。”教师对于一些数学概念,不必自己提出,从学生熟悉的生活情境或感兴趣的事物出发,提供观察和实践的机会,能充分发挥学生学习的主动性,激发学生自主探索的欲望。如《认识物体》这一课的导入:(教室内布置一棵圣诞树,挂上各种形状的礼盒)师:圣诞节到了,圣诞老人给我们小朋友送来了那么多的礼
It is well-known that mathematics has perfect beauty, symmetrical beauty, concise beauty and abstract beauty, which is the beauty of mathematical science itself. If in the classroom, more to give students insight into mathematics time and space, so that the process of perception of rich and colorful, such mathematics teaching is beautiful, mathematics learning is beautiful, such mathematics classroom is beautiful. First, the creation of the situation, the United States at the very beginning, “the best stimulus for learning, but the interest of the materials studied.” Teachers for some mathematical concepts do not have to put forward their own, from the students familiar with the situation or interesting things, Provide opportunities for observation and practice, give full play to students ’initiative in learning, and stimulate students’ desire to explore on their own. Such as “know the object” This lesson: (classroom layout of a Christmas tree, hanging a variety of shapes gift box) Teacher: Christmas is over, Santa Claus sent us so many gifts
