Student should not use mobile phones in class2 Students would rely too much on their mobile phones if they use their phones in class. First of all, once students use mobile phones frequently, they may not want to solve learning problems by themselves but they would just check for answer online.A study shows that smartphone users who are intuitive thinkers prefer to depend on their device’s search engine instead of their own brainpower(University of Waterloo,2015) .In this way smartphones make them become lazier in a long-term. Also,students would cheat in test with their smart phones .According to Common Sense Media(2009),more than 35% teenagers admit to cheating with their cell phones ,and many students do not think their actions are cheating. In other words ,those students get use to checking information online to solve problems so that they take it for granted that they can use smart devices in test.In short,students would depend too much on their phones in class.
