《实验教学与仪器》杂志1993年第3期发表的《介绍两个自制的自然实验仪器》一文中的“人体触电演示器”,提出向学生进行安全用电的教育是十分重要的,这种提法无疑是正确。但介绍的“人体触电演示器”用于对小学生进行模拟触电实验的作法,本人认为有些不妥。 该文介绍的“人体触电演示器”安排在小学自然第六册的“导体和绝缘体”的内容中进行实验,用以说明人体是导体,同时要注意安全用电,用这个仪器实验,确实能很好地证明以上问题。这是该仪器可取之处。但是另一方面,用该仪器对小学生进行模拟触电实验,对他们的心理和以后学习有关电的知识不利。
“Electrostatic Presenter of Human Body” in the article “Introduction of Two Homemade Natural Experimental Instruments” published in Journal of Experimental Teaching and Instrumentation, No.3, 1993, proposes that it is very important to educate students on safe power supply. The formulation is undoubtedly correct. However, the introduction of the “human body electric shock presenter” for primary school students to simulate the practice of electric shock, I think there is something wrong. This article describes the “human electric shock presenter” arranged in the elementary school sixth volume of the “conductor and insulator” in the content of experiments to illustrate the human body is a conductor, and pay attention to safe use of electricity, with this instrument experiment, really can Good proof of the above problem. This is where the instrument is desirable. However, on the other hand, simulating electric shock experiments on pupils using this instrument is unfavorable to their psychology and their later knowledge of electricity.
