| 對于放射性，對于核輻射，人們幾乎可以說“談核色變”。如何在教學(xué)中利用近代物理實驗中有關(guān)放射性的實驗設(shè)備，使學(xué)生通過親身實驗和切身體會感受放射性對于周圍環(huán)境的影響，以及各種射線同物質(zhì)的相互作用，是在學(xué)生專業(yè)書面知識學(xué)習(xí)之外的另一種收獲。一方面學(xué)生可以加強自身科學(xué)素養(yǎng)，建立良好的關(guān)于輻射安全的安全意識，另一方面知道放射源并不可怕，對放射源無端的恐懼是沒有必要的。本文基于商丘師范學(xué)院物理與電氣信息學(xué)院的教育教學(xué)實踐，在“用快速電子驗證相對論效應(yīng)”的實驗中通過拓展實驗加深學(xué)生對放射性的了解，理解核輻射物理本質(zhì)，培養(yǎng)有關(guān)核物理知識的科學(xué)素養(yǎng)。 |

About radiation, or nuclear radiation, it almost can be said that "the mere mention of the nuclear talks". Explorations of the use of experimental equipments on radioactivity in modern physics experiments in teaching could help students experiencing and being keenly aware of the influence of radiation on the environment,as well as the interaction between radiation and other matter. These are another kinds of learning besides the book knowledge.In this way,on the one hand, students can enhance their scientific literacy, establish good radiation safety consciousness, on the other hand, be aware of the radioactive source is nothing horrible. Thus,unwarranted fear of radioactive source is unnecessary. This paper is written based on the teaching practice of physical and electrical information colledge in Shangqiu Normal University, through the expanded experiments of verificating the relativistic effect by using fast electronic, we expected to deepen students' understanding of radioactivity,to understand the physical essence of nuclear radiation and to foster the science literacy of nuclear physics. |

Towards Radioactivity or Nuclear radiation, It can almost be said that "turn pale at the mention of nucleus" to people. Exploring the ways to use radioactive laboratory equipment in Modern physics experiments during school teaching. Making students to experence the impacts of radioactivity on the environment and discovering the interaction among various radiations, it can be a great harvst beside student's knowledge from professional books. On the one hand, Students can strengthen their own scientific literacy and establish a good safety awareness on radiation safety. on the other hand, they can realise that radioactive sources is not terrible and unwarranted fear of radioactive sources is not necessary. Based on the Teaching Practice from the Physics and Electrical Information college of Shangqiu Normal University, the thesis was use to deepen students' understanding of radioactivity by the extending experiments of "verifing the Relativistic effects with fast electronics", and to Understand the physical nature of nuclear radiation to develop scientific literacy of nuclear physics. 自己再改下吧 |
