如何使学生在实验中充分调动积极性,变被动为主动,在实验中不划框框,不预先给出实验应得到什么结论,而提倡让学生在共同选定的课题下,自己去思考、自己设计实验方案、自己动手操作、自己得出结论,能使知识的传授、技能的提高和能力的培养融为一体,我在《生理卫生》的学生分组实验“脊蛙的反射实验”中,作了一次学生自己设计实验的尝试。脊髓具有反射和传导二个功能。学生分组实验规定的目的,只是观察脊蛙的反射功能。一般情况下,学生是能一步步按教材要求完成实验,并得到蛙的脊
How to enable students to fully mobilize the enthusiasm in the experiment, change from passive to active in the experiment not to frame the box, do not give the experiment in advance what conclusions should be obtained, and to encourage students to jointly selected under the topic of thinking, to design their own Experimental program, do it yourself, come to their own conclusions, can make the transfer of knowledge, skills and ability to cultivate integration, I group in the “health” students “Rana reflex experiment”, made A student’s own experiment in designing experiments. Spinal cord has two functions of reflection and conduction. The purpose of the student grouping experiment is only to observe the reflex function of the frog. Under normal circumstances, students are able to complete the experiment step by step according to the textbook, and get the frog’s ridge
