地理教学中的直观教学除用地图外,还可用立体模型进行教学。购置一只立体的地理模型,价钱比较昂贵,在客观条件的限制下,我们可以设法自己制造。立体模型的制造方法很多,其中以纸浆堆塑较为简便,而且所费的成本也较小。现在把我堆塑中国地理立体模型的方法介绍於後,以供参考。(一)制纸浆:先收集学校里的毛边纸质的废考卷、旧簿子,用水浸透,放入石臼中捣成非常细腻的糊状浆液。纸浆捣成後,滤去水份,以融溶的牛皮胶倒入(一面盆的纸浆约加入含胶百分之七十的胶水半面盆),拌成可塑性的粘质,这样就可以在底板上堆了。
Intuitive teaching in geography teaching in addition to map, but also can use three-dimensional model for teaching. The acquisition of a three-dimensional geographical model, the price is more expensive, objective conditions, we can try to create their own. There are many ways to make the three-dimensional model, in which it is easier and easier to build plastic pulp. Now I piled plastic geosynthetics China three-dimensional model introduced later, for reference. (A) the system of pulp: first collection of school burr paper scrap paper, old book, soaked in water, into the mortar mortar into a very delicate paste-like slurry. After the pulp is triturated, the water is filtered off and poured into dissolving kraft glue (a pot of pulp is added with about 70% glue half basin) to mix the plasticity of the mucilage, Heap up.
