When students use tablets, instead of textbooks, they are not learning the best way they can. Students can use tablets to access video games and email accounts, which are distractions in class. In the classroom, students should be concentrating on learning school tasks rather than playing games and socializing on their tablets. Additionally, students can use tablets to access the Internet where they can find quiz or test answers rather than learn the subject matter for themselves.
According to experts, excessive use of tablets causes eyestrain, headaches, and blurred vision for students. Health experts also say that using tablets can cause neck pain, shoulder pain, and carpal tunnel syndrome.
Furthermore, tablets cost more money than traditional textbooks. It is estimated that schools which buy tablets for every student will pay almost five times more than they would for purchasing textbooks. Schools also have to consider theft or damage of tablets and purchase insurance for the devices. Moreover, replacement and upgrading costs need to be considered. Conversely, textbooks are less likely to be stolen. Also, oftentimes, damaged textbooks can be easily repaired with tape or glue.
