在生物教学中,剪贴图的使用是经常的,我根据几年教学体会,采用一种用尼龙纱张挂剪贴图的方法,效果较好,其具体做法如下: 一·买一块长一点六公尺左右的单色尼龙窗纱(不要买带花纹图案的),并将两头用木板条夹固,一头拴好绳线。二·画好并剪好所需挂图,如有现成挂图,为了出示有先后顺序,也可把挂图一一剪下,如有丝分裂挂图等。 In the biological teaching, the use of clip-art is often, I learned from a few years of teaching, using a method of hanging with a nylon yarn hanging clip map, the effect is better, the specific practices are as follows: Buy a 1.6 Monochrome nylon screens around the feet (do not buy the pattern with a pattern), and the two ends of the wooden slats, one tied the rope line. Second, draw and cut the required wall charts, ready-made wall charts, in order to show the order, but also cut the charts one by one, such as mitotic wall charts.
