Disadvantages and Advantages of Handphone
Handphone also known as mobile phone or cell phone or smart phone, and is an electronic device used for mobile telecommunications (mobile telephony, text messaging or data transmission) over a cellular network of specialized base stations known as cell sites. Martin Cooper invented the handphone. He is a Motorola researcher and executive. Martin made the first call on a handheld mobile phone on April 3, 1973. Cells for handphone base stations were invented in 1947 by Bell Labs engineers.

Handphones generally obtain power from batteries, which can be recharged from a USB port, from portable batteries, from mains power or a cigarette lighter socket in a car using an adapter often called battery charger or wall wart and from a solar panel or a dynamo that can also use a USB port to plug the phone. In addition to the battery, GSM handphones require a small microchip, called a Subscriber Identity Module or SIM Card, to function.
Each SIM Card is activated by use of a unique numerical identifier; once activated, the identifier is locked down and the card is permanently locked in to the activating network. Handphone are a most useful tool. They has an alarm clock, a watch, an internet browser, a personal organizer, a calendar, a camera, a video camera, a voice recorder, a text messages, a GPS device, and a calculator, among other things. Rather than fear this new device, we need to embrace the technology and direct its use to support our mission of developing productive and civil citizens.
We need to work to find ways in which to use this tool in class and to encourage the appropriate use of handphones in the same way we work to develop positive use of the Internet and explain the idea of netiquette online. There are many useful applications for mobile devices. Pod casting, live broadcasting, replying in real time to polls and quizzes in class, photo sharing, video sharing, and research online are just some of the ways this tool can be used in class. Handphones are used for a variety of purposes, including keeping in touch with family members, conducting business, and having access to a telephone in the event of an emergency.
Some individuals keep multiple handphones in some cases for legitimate reasons such as having one phone for business and another for personal use, though a second handphone may also be used to covertly conduct an affair or illicit business transaction. Child predators are able to take advantage of handphones to secretly communicate with children without the knowledge of their parents or teachers, which has raised concerns. The most commonly used data application on hand phone is SMS text messaging, with 74% of all handphone users as active users (over 2. billion out of 3. 3 billion total subscribers at the end of 2007). SMS text messaging was worth over 100 billion dollars in annual revenues in 2007 and the worldwide average of messaging use is 2. 6 SMS sent per day per person across the whole handphone subscriber base (source Informed 2007). Handphone technology has improved drastically in the last few years. Even more drastic improvements and changes are just around the corner. Keeping up with technological advances is not easy, particularly when benefits and drawbacks may not be clear, but it is necessary.
Well-thought-out handphone policies enable schools to continue to reflect the society they serve. Digital responsibility and citizenship is a 21st century skill we need to develop within our students. Simply banning handphone from school is taking on a losing battle. I believe that teachers should need to accept the handphone as a part of their students’ lives and work to incorporate this new tool into the classroom environment. The most important advantage of handphones is that we can use them almost everywhere without cables or electricity. By using handphones, you can communicate with everyone whenever you want and wherever you are.
Beside this, if there is an urgent situation, such as an accident or a meeting with someone, we certainly need a hand phone. Furthermore, we can access the internet by using a cell phone. Recently, the most common way of communication in the world has been the SMS. Handphones are not only used for communication, but they can also be used for taking pictures, listening to music, playing games, getting onto the internet, and so on. Advantages: Handphone can be a lifesaver It can be a lifesaver in emergency, students may provide vital or timely information to the police.
It is good for law enforcement officials to be able to track the events leading up to and during the emergency through the use of handphone calls. Besides that, students are certainly upset and need to be able to communicate with their parents and loved ones. This makes a handphone a necessity for school. A CBS News online article, School Cell Phone Ban Causes Uproar stated, “Yen Ramirez, a junior at Manhattan’s Washington Irving High, said students need their phones for emergencies. The ban is a problem “because you never know what could happen. ” There have been school shootings and school lock downs in emergencies.
Handphones could be a needed line of communication in difficult situations. Emergency Parents are able to contact their children when there is emergency or urgent situation. Student at school needs access to quick help or rescue. This is a sad reality, but it is true. Since handphones are lower in price for families with plans that allow air time to be shared between family members, it is entirely possible to provide children with handphones. If there is an emergency at their school, students have a way of contact the police to report the problem. To be able to contact their parent
Handphones are essential tools; it is useful to both parents and students when scheduling after-school activities and changes in family plan. It is for the peace of mind for parents. Parents rely on handphones to be able to contact their children when they go out after school, and use handphones to reassure their child when they are running late or if they cannot pick their child up. Learning Handphones have many features that could be easily incorporated into classroom learning. Most of the time computer labs are not able to be accessed by classroom teachers other than those teaching information technology courses.
An online article Controversy in the Classroom, by Katherine Shaw states, “For schools with limited technologies available to students, handphones imitate the computers that the classroom may lack. ” Handphones may have texting capabilities, voice recorders, cameras and video cameras, as well as access to the Internet. For instance, student may access learning material in different forms either through authority or visually by text on a screen. Students may not have the same handphone with the same technology capabilities but offering them options with differentiated instruction could lead to a variety of projects to be shared in class.
Handphone can be a dictionary tool in it. For example, if the student are facing some problem in pronunciation, they can check on the dictionary and pronounce it correctly, this can improved their learning skill. Handphone is also a reminder for student, so those students are able to remember thing that are important. According to SMK La Salle (Petaling Jaya) principal A Rajenthran said that, we allowed students to bring their handphone for convenience and security reasons. “Many parents want to be able to contact their children. They also want their children to be able to contact them in case of an emergency. We set up a process where students who want to bring their handphone can do so, but they have to first register with us. ” We cannot run away from the fact that handphones make things extremely convenient these days. ” Bringing Handphones to School can Boost Students’ Responsibility In a way, bringing handphones to school can actually boost the students’ responsibility. Therefore, they would have learned a valuable lesson of responsibility to take care and avoid lose their handphones. Besides that, students are reminded that they are bringing handphones to school at their own risks.
Schools can confiscate student’s handphone if they do not comply with the guidelines. Handphones Can Save Students’ Times Students can use the camera application to capture the important notes that teacher give within few seconds compare to copy word by word using and waste lots of time. Therefore, teacher can use the remaining time to continue the curriculum. Handphones Can Help Students Be More Organized Most students will not carry a paper planner. We need to integrate their handphones devices as their planner – giving them homework reminders, letting them poll, podcast, blog, and study using these mobile devices.
They have them with ALL of the time which make is perfect for using as a planner. According to the Franklin Covey planning course, rule number one was “Always have your planners with you. ” Students can be reminded of things from their Google Calendar, which integrates with the calendar use for planning. You’re fighting a losing battle Many educators are seeing that truly, banning cell phones is not a battle that is going to be won. We think that parents are going to demand that it be on their child for safety reasons. The chaperone feature lets the parents use GPS to know where their child is at all times.
