题目内容

教学设计一：在教学求平行四边形面积时，教师讲授如下：连接AC，因为三角形ABC与三角形CDA的三边分别相等，所以，这两个三角形全等，三角形ABC的面积等于1/2底乘高，所以，平行四边形ABCD的面积等于底乘高，命题得到证明。然后，教师列举很多不同大小的平行四边形，要求学生求出它们的面积，结果每个问题都正确解决了。下课前，教师又布置了十几个类似的问题作为家庭作业。教学设计二：教师引导学生分析问题，即如何把一个平行四边形转变成一个长方形，然后组织学生自主探究，并获得计算平行四边形面积的公式。问题：两种教学设计中教师的教学方法有何不同两种教学方法对学生的学习将产生怎样的影响

It has been either my good or evil lot to have my roving passion gratified. I have wandered through different countries, and witnessed many of the shifting scenes of life. I cannot say that I have studied them with the eye of a philosopher; but rather with the sauntering gaze with which humble lovers of the picturesque stroll from the window of one print-shop to another; caught sometimes by the delineations of beauty, sometimes by the distortions of caricature, and sometimes by the loveliness of landscape. As it is the fashion for modem tourists to travel pencil in hand, and bring home their portfolios filled with sketches, I am disposed to get up a few for the entertainment of my friends. When, however, I look over the hints and memorandums I have taken down for the purpose, my heart almost fails me at finding how my idle humor has led me aside from tile great objects studied by every regular traveler who would make a book.
