在生理卫生教学中,我们采取综合实验的方法,集中时间、集中内容进行生物生理、形态、解剖等方面的综合实验,取得了较好的效果。具体做法是: 第一步,自编实验提纲印发给每个学生,包括实验顺序、原理、目的、步骤、思考题。第二步,学生结合提纲预习实验内容。第三步,学生在实验小组里连续做完规定的实验内容,教师巡回指导。第四步,做好实验作业(绘图、练习题)。进行生物综合实验、关键的一步是教师要巧妙编排好实验顺序,科学地设计思考题,才能使众多实验内容有条不紊顺利地完成,以达到预期目的。例如,用一只青蛙(或蟾蜍)一次可做完六项实验内容,其 In the teaching of physiology and hygiene, we have taken a comprehensive experimental approach, focused on time, focus on the contents of the biological physiology, morphology, anatomy and other aspects of the comprehensive experiment and achieved good results. The specific approach is: The first step, self-prepared experimental outline issued to each student, including the experimental order, principles, purpose, steps, questions. The second step, students combined with the outline of experimental content. The third step, the students in the experimental group in a row to complete the provisions of the experimental content, teachers tour guide. The fourth step, do a good job experimenting (drawing, practice). For biological comprehensive experiment, the key step is that the teacher should skillfully arrange the experimental order and scientifically design the thinking questions so that many experimental contents can be completed in an orderly and orderly manner, so as to achieve the expected goal. For example, a single frog (or toad) can do six experiments at a time
