利用移动终端让“暗箱课”变暗为明——以执教《食物的旅行》为例

Use the Mobile Terminal to Turn the "Black Box Class" from Dark to Light——Take teaching "food travel" as an example

小学科学教材中,有些内容是不能直接感知的,但根据一定的可感知的外部情况,可以间接推断出来,这一类内容在教材中常以"解暗箱"的形式出现。随着时代的进步,移动终端进入教学视野,它以丰富的学习资源为依托,能够让学生利用平板电脑进行线上虚拟学习,改变学习方式,解决了科学"暗箱课"不易直接探究的缺点。在《食物的旅行》这一课教学中,笔者借助移动学习终端的优势,使移动终端与小学科学教学深度融合,提高课堂品质与教学效率,打造智慧课堂,在移动终端上实现师生交流、生生交流,解决"暗箱课"的学习难点。

In primary school science textbooks,some contents cannot be directly perceived,but can be inferred indirectly according to certain perceptible external conditions.This kind of content often appears in the form of"solving the dark box"in textbooks.With the progress of the times,the mobile terminal has entered the teaching field of vision.Relying on rich learning resources,it can enable students to use tablet computers for online virtual learning,change learning methods,and solve the disadvantage that it is not easy to directly explore the scientific"black box course".In the teaching of food travel,the author makes use of the advantages of mobile learning terminal to deeply integrate mobile terminal with primary school science teaching,improve classroom quality and teaching efficiency,create smart classroom,realize teacher-student communication and student communication on mobile terminal,and solve the learning difficulties of"black box class".
