Ins this Information students will aware about the cons of cell phone in the classroom

1. Cons Of Using Mobile
Phones.

2. 1. Distraction
Scientists from Hokkaido University in Japan said that their findings show that it is harder to
concentrate when one of the electronic gadgets is present.
Researchers measured the time it took to find the target. People asked to carry out electronic
tests of their attention spans were found to perform worse when a mobile phone was present
than other people performing in the presence of a paper notepad The results of the experiment
found that those with the mobile phone took longer to find the character ‘indicating that
participants were automatically distracted by the presence of the phone’, the authors said. The
researchers suggest that people are ‘drawn to the presence of a mobile phone’ although there
are individual differences in how one attempts to ignore it. In conclusion, Professor Kawahara
said ‘The mere presence of a mobile phone was a distraction among infrequent internet users.’
The evidence that mobile phones is distracting has been piling up in recent years. Many studies
have shown that talking on mobile phones impairs driving performance.

3. 2. Cheating of exams:
Data obtained by the Guardian through freedom of information requests found a 42% rise in
cheating cases involving technology over the last four years – from 148 in 2012 to 210 in 2016.
Last year, a quarter of all students caught cheating used electronic devices.

4. 3. Epidemic Obesity
TV and video game use correlates with increased obesity (Tremblay 2005). Children who are
allowed a device in their bedrooms have 30% increased incidence of obesity (Feng 2011). One in
four Canadian, and one in three U.S. children are obese (Tremblay 2011). 30% of children with
obesity will develop diabetes, and obese individuals are at higher risk for early stroke and heart
attack, gravely shortening life expectancy (Center for Disease Control and Prevention 2010).
Largely due to obesity, 21st century children may be the first generation many of whom will not
outlive their parents (Professor Andrew Prentice, BBC News 2002).

5. 4. Sleep Deprivation:
60% of parents do not supervise their child’s technology usage, and 75% of children are
allowed technology in their bedrooms (Kaiser Foundation 2010). 75% of children aged 9 and 10
years are sleep deprived to the extent that their grades are detrimentally impacted (Boston
College 2012).

6. 5. Mental Illness
Technology overuse is implicated as a causal factor in rising rates of child depression, anxiety,
attachment disorder, attention deficit, autism, bipolar disorder, psychosis and problematic child
behavior (Bristol University 2010, Mentzoni 2011, Shin 2011, Liberatore 2011, Robinson 2008).
One in six Canadian children have a diagnosed mental illness, many of whom are on dangerous
psychotropic medication (Waddell 2007).

7. 6. Health Hazard
Mobile phones use Radio Frequency (RF) waves in order to transmit signals to and fro
A compelling instance of health hazards as one of the disadvantages of mobile phones was an
experiment performed by Swedish researchers where they studied the effects of exposure to
microwave radiations for two hours on rats’ brains. They found that a large number of dead
brain cells were found in the rats’ brains after fifty days. Degeneration of brain cells in humans
leads to serious diseases like Alzheimer’s disease, Parkinson’s disease among others. Although,
the linkage of mobile phone usage with Alzheimer’s and cancer are not completely established,
however, even a modicum of truth in these findings has major ramifications.
Although not yet completely proven, mobile phones are also associated with a number of other
ailments such as cancer, difficulty in concentration, fatigue, headaches and sleep disturbance to
name a few.

8. 7. Reduced Cognitive Ability
A smart phone offers numerous conveniences, including easy access to calculators, dictionaries
and other tools. However, "The Atlantic" reports that they're taking a toll on students' cognitive
thinking abilities. Attention spans have shortened so dramatically that many college students
struggle to read anything longer than a social network posting. In addition, becoming dependent
on the phone as a quick fix for information can keep them from developing the ability to "think
on their feet" in work situations.

9. Other Disadvantages
Inappropriate content
Cyberbullying
Mobile devices disconnect students while at school
Several cell-phones can overload a school-network
Cell-phone technology increases on inequality within students at school
Increased theft at school
Cell-phones can interrupt lessons at school
