Cell phones are great technical devices and important today in modern life, but they should not be allowed in the class room. Cell phone use should be saved for after class. They could be used for researching things for class but not while in class. Cell phones are distracting, can be used for cheating, and are even disrespectful to the teacher.
Cell phones are a huge distraction to students and even teachers. A ringing cell phone can pause the whole class and slow the momentum of the teaching.
It greatly affects students learning by the temptation of it being right in their pocket. A vibrating cell phone is almost instinct to check right away, therefor distracting what could be a very important point in the lecture. When bored with the lecture going on students can easily surf the web, get on social media, and send text messages. If they were allowed, it would be all too easy to pull up twitter instead of doing something beneficial to learning.
Students cannot be expected to learn if they are not even paying attention
As a student cheating can be tempting. A cell phone makes that even worse. Cheating in the classroom is the worst thing you can do, and cell phones make that easier. Notes used to be passed to cheat but now cellphones are used. Students can take pictures of the test and answers and send them to many other students and before long the whole class could have it. Taking it even farther students can ask to be excused to go to the bathroom and send texts to get answers.
Cell phones nowadays are advanced enough that students could look up test answers quickly at the palm of their hand. The possibilities for cheating using a cell phone are limitless.
Among all these things it is also disrespectful to the teacher to look at your phone while they are trying to give you knowledge to better yourself.
Some professors would even kick students out. Any person does not like when they are talking to someone and they are not listening just looking down at their phone. This case is much worse in a classroom setting; the least you could do is give your attention to someone trying to teach you.
From all of the cons of cell phones in the classroom, it can be concluded that they should not be allowed. They cause a lot of distractions from sounds to the temptation to surf the web. Cheating is made a lot easier with cell phones and more widely used now. Most importantly it is also disrespectful to the teacher and could result in getting kicked out of the classroom.
