《蝙蝠和雷达》一课的教学接近尾声。基于说明文语言的严密性和逻辑性,作者对蝙蝠的夜间飞行原理和雷达工作原理的介绍近似白描。因此,孩子们对“仿生学”这一拓展知识的学习兴趣也大打折扣。联想到孩子们最近比较迷童话、科幻类小说,我不禁在“蝙蝠”和“雷达”上动起了脑筋:蝙蝠和雷达虽然是两种不同的事物,但蝙蝠的飞行原理和雷达的工作原理有密不可分的联系,如果以童话的视角,让它们置于同一个情境进行对话,很多问题不就迎刃而解了吗?于是,我安排了这 Teaching “Bat and Radar” is coming to an end. Based on the rigor and logic of the descriptive language, the author’s introduction to the bat’s nighttime flight principle and radar’s working principle is approximated by a white sketch. As a result, children are also greatly reduced in their interest in developing the knowledge of bionics. I can not help but think that children are flirting with fairy tales and sci-fi fictions recently. I can not help but think about bats and radars. Although bats and radars are two different things, the bat’s flying principle and The working principle of radar is inextricably linked, if the fairy tale perspective, let them put in the same situation for dialogue, many problems not solved? So, I arranged this
