Kim, Lee, and Kim (2014), for example, reported students feeling unhappy about having to search for resources on cell phones or type a lengthy opinion due to the small keyboard and screen size. Some students also thought that using MIM was time-consuming (Hazaea & Alzubi, 2016), while others disliked getting class-related messages outside school hours because this interfered with their private lives (So, 2016).
Kim等学者发现部分学生反应MIM存有屏幕小,搜索不便,耗时长以及课外打扰等不良作用,但是同学们所反应出问题,并没有直接的推出MIM在教育质量的危害。
