在物理教学中,如果能巧妙地利用日常生活用品保鲜袋,就能使复杂的问题简单化,深奥的问题形象化,抽象的问题直观化,呆板的问题生动趣味化,从而达到激发学生的学习兴趣和学习积极性,活跃课堂气氛,提高教学效率,开发学生智能,培养其创新精神和实践能力的目的。一、水袋使字画变大实验用小号较厚的保鲜袋装适量的水,扎紧袋口,用手提着保鲜袋,让盛水的保鲜袋形状近似构成一个凸透镜,作为放大镜,让学生观察保鲜袋前面的字画,学
In physics teaching, if we can cleverly use the daily necessities preservation bag, we can make the complex problems simple, the profound visualization of the problem, the abstract visualization of the problem, the rigid problem of vivid interest, so as to stimulate student learning Interest and learning enthusiasm, active classroom atmosphere, improve teaching efficiency, develop student intelligence, develop their innovative spirit and practical ability. First, the water bag to make the larger calligraphic experiments Trunk thick with a small amount of fresh storage bags of water, tie tight pocket, with a hand-held fresh bag, so Shengshui preservation bag shape approximation to form a convex lens, as a magnifying glass, so that students Watch bags in front of the calligraphy and painting, learning
