2、 investigation, researchers found that students who were permitted to use laptops or tablets in the classroom performed worse than those who did notand those with higher initial GPAs平均成績(jī) were most heavily affected.    While some argue that laptops aid students in note-taking and compr

3、ehension, many say that they couldnt pay attention to the lessons. To get to the bottom of the issue, researchers investigated the effect of laptops and tablets on student performance in a course at a school.    In the study, the class was then divided into two treatment groups. The f

In the second group, students could only use tablets, making the screen easily visible to the professors.

5、 When it came time for final exam scores, the researchers found that using a laptop or tablet in the classroom had caused a drop of roughly one-fifth of a standard. The results for the two treatment groups were nearly the same, they say.     And, the negative effects were seen mo
