在上动物解剖实验课时,教师常常遇到的一个难题是示范操作学生看不清或者根本看不见;指导解剖实验时,尽管语言表达清晰也不易被全部学生理解和接受。实验课堂秩序杂乱,实验效果差,如何能够解决这个问题?我们在几所学校进行纸质模拟模型解剖试验,取得了一些经验,现简介如下。 上家兔解剖实验课时,老师事前备用一块小黑板,上面重叠复盖三张大白纸。在同一部位,第一张纸绘上家兔被捆绑待解剖状
In the animal anatomy experiment course, one of the problems that teachers frequently encounter is that the demonstration operation students cannot see clearly or not at all. When the anatomy experiment is directed, although the language is clearly expressed, it is not easy for all students to understand and accept. The experimental classroom is disorderly and the experiment results are poor. How can we solve this problem? We have conducted paper anatomy experiments on simulation models in several schools and gained some experience. The brief introduction is as follows. When the rabbit was dissecting the experimental class, the teacher used a small blackboard beforehand to overlay three large blank papers. In the same place, the first piece of paper is painted on the rabbit and it is tied up for anatomy
