预习是教学过程的重要环节,研究显示,人对事物的记忆是以图片的形式储存在大脑里,相对于纯文字的记忆,图片影像的形式更利于学生预习和理解。本文主旨是利用移动设备的普及性、学生对移动设备的依赖性,采用教学内容相关的化学实验软件,让学生进行简单明了的课前预习,提高学生化学实验的学习效果。 Preliminary study is an important part of the teaching process. Research shows that people’s memories of things are stored in the brain as pictures. Compared with plain text memories, the form of imagery is more conducive to students’ preparation and understanding. The purpose of this paper is to make use of the popularity of mobile devices, students ’dependence on mobile devices, and the use of chemistry experiment software related to teaching content to enable students to make simple and simple pre-class exams and improve students’ learning effects in chemical experiments.
