Students should be allowed to use smartphones in class. What extent do you agree or dissagree. These days, people have different viewpoints about whether or not we should let pupils use smartphones in learning. Some agree, some reject this opinion. However, from my perspective, I strongly disagree with the idea that students should be given access to science-related devices at school. Firstly, using cell phones in class may distract youngsters from thier studies. Should young adults have the right to make use of smartphones, they will only pay attention to these electronic devices without focusing on what the teacher is conveying. Therefore, students' performances at school can be affected badly. Secondly, health problems may happen if pupils use smartphones in learning since they keep concentrating on the applications. Consequently, young adults'eyes can be seriously influenced. Furthermore, the communication skills of youngsters may suffer from negative effects as students do not talk to each other but continue to use electronic equipments. Some people believe that science-related devices can provide pupils a better learning envirionment. Yet, I want to point out that yound adults may cheat in examinations by searching keys on the Internet. Moreover, teachers can offer youngsters vivid pictures and videos instead of allowing them to use cell phones. Thus, students can understand the lessons clearly. In conclusion, I am totally disagree with the opinion that pupils should be allowed to use smartphones when learning because of its numerous drawbacks.
