Mobile Phone In Teaching
The Importance of Mobile Phone in Education
By Terry Freedman
From listening to music, to taking and editing pictures of teachers, the young community have found various ways to misuse the new technology being made available to them in such small and compact mobile phones. Obviously, anything that can disrupt learning, or teaching, cannot be accepted in a classroom environment and should be dealt with accordingly. It is my opinion that as technology advances at such a blistering pace, policies such as ‘mobile phones should be switched off and in your bag’, can be modified to benefit not only students, but teachers and schools alike.
As a student who has experienced some very rowdy and distracting classes, I know that mobile phones can cause huge distractions for not only students, but teachers as well. I am also aware that mobile phones can be a danger to the school environment; however I believe they can still have their benefits in the classroom.
As a very proud owner of an Apple iPhone 3G, I could rave all day about the importance of my mobile phone. It keeps me in contact wherever I go, which not only gives me peace of mind, but also my parents! An argument I have never understood is that youngsters have become too reliant on their mobiles. Nowadays mobile phones can be as useful to people as a pencil and paper, and I have never come across an argument that adults have become too reliant on those!
The ability to download ‘apps’ to phones such as the iPhone can also make it not only personalised, but useful for people in most situations. From word processing software to a program that keeps an eye on the stock market, the range of potential uses can just not be argued with. For example, instead of waking up tired and grumpy, I use an advanced alarm clock to measure my sleeping patterns which also wakes me up when I am sleeping at my lightest. Not entirely necessary, but this could still be beneficial to anybody!
So if this level of technology can benefit from city workers to journalists, why can it not be taken advantage of at school? I have numerously thought to myself in lessons such as Spanish and English that if it was accepted for me to use my phone, my learning could be improved. Instead of taking out a dictionary, I could simply use my translator, and instead of trawling through books for a piece of literature, I could find the book online and be directed to a specific word, and so on. The fact is that these phones are really just computers, yet I am unaware of a school that is reluctant to allow the use of these.
I'm not naïve; firstly not everybody has such an advanced phone and secondly, there are bound to be people who will take advantage. But as technology becomes cheaper, more people will invest in this equipment, and surely the people who take advantage of the leniency would use their phone regardless of new measures?
Schools themselves are modernising greatly. My present school, for instance, is in the process of becoming an academy. This means that from September 2010 it will no longer be classed as a ‘school’, and by 2013 it hopes to have established completely new buildings. I am part of a group of students who have listened to the new plans, and I was impressed with the new technology being considered. Ideas such as giving each student a laptop and registering attendance online are being planned already. I think it is fantastic that schools are finally ‘getting with the times’ and are understanding the importance of ICT in education! Eventually I hope mobile phones will be looked upon in a much more reasonable way and take a more important role in education. After all, there’s only so much fun you can have with editing teachers’ faces!

Avoid Harmfull Radiation of Mobile Phones
Mobile Phone Radiation to Unleash Epidemic of Brain Tumors
by: David Gutierrez
NaturalNews) A new review of more than 100 studies on the safety of mobile phones has concluded that cellular devices are poised to cause an epidemic of brain tumors that will kill more people than smoking or asbestos.
The review was conducted by neurosurgeon Vini Khurana, who has received more than 14 awards in the past 16 years, who made headlines worldwide with his warnings. He called upon the industry to immediately work to reduce people's exposure to the radiation from mobile phones.
According to Khurana, research demonstrates that long-term use of mobile handsets, more than 10 years, can double the risk of contracting brain cancer. While a number of studies have concluded that there is no such risk, Khurana said that most of those studies only examined short-term use. But because a brain tumor can take 10 years to develop, studies without a long follow-up period are largely meaningless.
"There is a significant and increasing body of evidence for a link between mobile phone usage and certain brain tumors," Khurana said, a link that will be "definitively proven" within 10 years.
Khurana urged people to minimize their use of mobile phones, particularly handsets. He also urged the industry to act immediately to reduce exposure to radiation from the devices.
While mobile phones may save lives in certain emergency situations, Khurana said, brain cancer is "a life-ending diagnosis."
"It is anticipated that this danger has far broader public health ramifications than asbestos and smoking," Khurana said. While one billion people worldwide smoke tobacco, three times as many now use mobile phones.
Smoking is responsible for five million deaths each year.
While the United Kingdom's Independent newspaper described Khurana's study as "the most devastating indictment yet published of the health risks" of mobile phones, his warning is not the first. A Swedish study in 2006 concluded that people who used mobile phones for an hour or more each day had a 240 percent higher brain tumor risk than non-users. Tumors were significantly more likely to develop on the side of the head where the phone was most often used.
Inspired in part by such studies, France has warned against mobile phone use (especially in children), Germany urges people to minimize their use of mobile handsets, and the European Environment Agency has called for minimizing exposure to cellular radiation.
The mechanisms by which mobile phones increase cancer risk are not well understood, but several possibilities are suspected. Electromagnetic radiation (EMR) is known to directly heat up the head and brain, and can also cause thermoelectric effects on cells and DNA. According to Khurana, even bluetooth devices and unshielded headsets merely turn the head into an antenna that bombards itself with radiation. Children, with thinner skulls than adults, are particularly at risk.
"EMR rays in general cause irritation, concentration lapses and in many cases even proliferation of cells which cause cancer," said Dr Rajeev Ranjan, a New Delhi neurologist. Radiation can also interfere with the functioning of medical devices like pacemakers.
EMR also "affect[s] the DNA and cause[s] problems in cell recovery and cell growth," said New Delhi neurologist Anshu Rohatgi.
