Secondary school is a term used to describe an educational institution where the final stage of schooling, known as secondary education and usually compulsory up to a specified age, takes place. It follows elementary or primary education, and may be followed by university (tertiary) education.
There are many different types of secondary school, and the terminology used varies around the world. Children usually transfer to secondary school between the ages of 10 and 16 years, and finish between the ages of 15 and 19 years, though there is considerable variation from country to country.
Depending on the system, schools for this period or a part of it may be called secondary schools, high schools, gymnasia, lyceums, middle schools, colleges, vocational schools and preparatory schools, and the exact meaning of any of these varies between the systems.
The secondary school students are those students of post-primary studies or as described above. It is at this stage of academics that students lay the foundation of their future. No matter what the student wants to be in life, the way is paved at this stage that is why most errors which are not corrected in secondary school lives with most students till the rest of their lives. Building people with global passion are deeply rooted in this stage of education.
A mobile phone (also called mobile, cellular telephone, or cell phone) is an electronic device used for two-way radio telecommunication over a cellular network of base stations known as cell sites. Mobile phones differ from cordless telephones, which only offer telephone service within limited range through a single base station attached to a fixed land line, for example within a home or an office.
A mobile phone allows its user to make and receive telephone calls to and from the public telephone network which includes other mobiles and fixed-line phones across the world. It does this by connecting to a cellular network owned by a mobile network operator. A key feature of the cellular network is that it enables seamless telephone calls even when the user is moving around wide areas via a process known as handoff or handover.
In addition to being a telephone, modern mobile phones also support many additional services, and accessories, such as SMS (or text) messages, e-mail, Internet access, gaming, Bluetooth and infrared short range wireless communication, camera, MMS messaging, MP3 player, radio and GPS. Low-end mobile phones are often referred to as feature phones, whereas high-end mobile phones that offer more advanced computing ability are referred to as smart phones.
The first hand held mobile phone was demonstrated by Dr. Martin Cooper of Motorola in 1973, using a handset weighing 2 kg (4.4 lb). Motorola released the first commercially 手機上台月費 available mobile phone, the DynaTAC 8000x in 1983. In the year 1990, 12.4 million people worldwide had cellular subscriptions. By the end of 2009, less than 20 years later, the number of mobile cellular subscriptions worldwide reached approximately 4.6 billion, 370 times the 1990 number, penetrating the developing economies and reaching the bottom of the economic pyramid.
Mobile phone has been an effective means of communication which has solved a lot of problems and poses a lot. It is mobile as the name, you can walk around with it play with it, sleep with it, travel with it and can equally go into the rest room with it. I see it as an important means of communication which has helped in many ways including times of danger, but is this seen among the students of secondary schools these days? The answer is NO! The mobile phone instead of doing well to this young generation or the called “future leader” it has caused a lot of harm to these upcoming geniuses. The questions now is, is it advisable for secondary school students to own a mobile phone? I mean students owning a mobile phone and not making use of mobile phone. Several reasons have been listed below why students of secondary should not own a mobile phone.
SIDE EFFECTS OF OWNING A PHONE BY STUDENTS:
Over the past decade the world has seen rapid growth in cell phone users. Everyone from older adults to kids in high school seem to carry one glued to their ears, without understanding the possible health risks associated with the use of cellular telephones.
To begin with, a recent scientific journal published in 2007 titled Long term use of cellular phones and brain tumors, concluded after assessing results from many different studies that use of cell phones for more then 10 years does show increased risk for acoustic neuroma and glioma. Adding that the risk is highest for ipsilateral exposure, meaning tumor on the same side of the brain where phone mostly held.
Research scientists behind this journal assert that most studies to date on cell phone use and brain tumors have been mostly conducted with an insufficiently long latency period. This journal report gives excellent reviews of other studies and evidence of data entry errors, systematic bias and mathematical errors within those studies.
The effect mobile phone radiation has on human health is the subject of recent interest and study, as a result of the enormous increase in mobile phone usage throughout the world (as of June 2009, there were more than 4.3 billion users worldwide. Mobile phones use electromagnetic radiation in the microwave range, which some believe may be harmful to human health. A large body of research exists, both epidemiological and experimental, in non-human animals and in humans, of which the majority shows no definite causative relationship between exposure to mobile phones and harmful biological effects in humans. This is often paraphrased simply as the balance of evidence showing no harm to humans from mobile phones, although a significant number of individual studies do suggest such a relationship, or are inconclusive. Other digital wireless systems, such as data communication networks, produce similar radiation.
