初中《生理卫生》教材中有一个“测试盲点”的实验.以往我们采用“马利奥特瓦”方法(测试板)进行盲点测试.虽作了实验,但教师在讲解“视网膜上盲点的位置是靠近鼻侧还是靠近相反的另一侧”这个问题时,一般只采用画图来抽象地讲解,学生不易理解,在头脑中难以形成正确的立体概念.为了解决这个问题,我们试制了盲点测试演示模型,以加强盲点测试实验的直观性,达到了良好的实验效果. There is a “blind spot” experiment in junior high school textbook “Physical Hygiene”. In the past, we used the “Marriott” method (test board) for blind spot testing. Although experiments were done, teachers explained the location of the blind spot on the retina. Whether it is near the side of the nose or the side opposite to the opposite side, this problem is generally explained only abstractly with a drawing. It is difficult for students to understand and it is difficult to form correct stereo concepts in the mind. In order to solve this problem, we have experimented with a blind spot test demo. The model is to enhance the blindness test’s intuitiveness and achieve good experimental results.
