ONLINE EDUCATION
DESCRIPTION OF THE SERVICE
Online education : "A CLASSROOM WITHOUT WALLS, IT'S ENGAGING IN ASSISTED, SELF DIRECTED LEARNING.”
Online education, also known as distance learning or e-learning, differs from traditional education because students are not required to visit an actual classroom and listen to an instructor face-to-face. Online education is truly about student convenience. Students can check in, work on assignments, and turn them in when their schedules permit, not when the college doors are open.
Online education means students no longer have to:
* quit their jobs to attend college,
* take time off from work to attend a specific course,
*spend hours in rush hour traffic or drive 200 miles to the nearest college or University,
It also means students:
*learn at their own pace,
*gain more one-on-one access to their instructors, and
*earn degrees in less time than it would take to juggle traditional courses.
How Online Education Works
After researching the best accredited institution, students are required to apply to one of the college's degree programs. Once accepted into an online program, students are asked to sign up for appropriate courses. After the registration process is complete and students are accepted into the program, the real work begins.
Students begin their course studies by logging onto the Internet. Once they're in their appropriate classroom, they'll learn by reading assignments, asking questions, and receiving instructor feedback. Some courses even offer forums and/or chat rooms where students can gather, with or without the instructor, to discuss assignments. Finally, students are graded on homework assignments, final projects, and test scores.
The most common function used in online education is electronic mail (email) that allows students and teachers to send messages to each other. In addition, most networks also provide conferencing capabilities that let participants conduct multi-person discussions either in real-time (often called "chats") or on a delayed basis (asynchronous).
All Courses Are Not Created Equally
Different programs require different levels of computer and/or Internet knowledge. Therefore, it is vital students take the time to speak with potential instructors, previous college students, and even the computer tech department to get a better understanding of the teaching methods and technology used.
Online instructors, like those teaching traditional courses, bring to their courses their own personal experiences, teaching objectives, and preferred methodologies. In addition, the institution's technology and technical support also influence learning experiences, Some courses are text and content-focused, while other courses emphasize more technical skill and interaction with technology.
ADVANTAGES OF ONLINE EDUCATION
E-education is definitely a good option to get a online degree to improve student’s career and living styles. Besides, there are so many advantages with which he/she can be benefited with if he/she pursue a distance learning course. Some of the benefits of online education are discussed below:
Low Cost:
Online studies cost less than any college direct programs. Universities and college charge very less tuition fee for any online course compared to the direct program.
A Flexible Time Schedule:
Students will be the master of their own schedule. Time is not a constraint in an online course. They can attend lectures, complete assignments and take exams at their own time.
Effective Learning:
Online learning is more effective due to technological involvement. Students will get study materials easily through the internet. Universities and colleges offering online programs are facilitating transcripts, live discussions and training materials which can be retrieved via mail, e-mail or the school's website for reading, downloading and printing. Instructors are also available at Students' convenient times and respond to queries quickly through e-mail.
Do not need to live in a hostel:
Students do not have to live in college hostel or any other place away from their home. They can stay at their home with their family and pursue the online course
Saves time:
Online schooling saves time. Students won’t have to spend time driving to school, finding a parking space and racing the clock to get to the classroom. His/her home is his/her classroom.
Students are the one in control:
Students plan their study time around their work or family time. They create the schedule. If something happens and he/she can’t keep his/her planned schedule due to an emergency or some other reason, he/she can still get all your work done when things get back to normal. This means he/she are the one in control. They set your own hours and their own pace for whatever works best for them.
The impact of negative body language or censuring tone:
Some learners feel uncomfortable speaking up in a traditional classroom because other learners give negative nonverbal cues, like frowning, rolling their eyes, sighing loudly, crossing their arms, or shaking their head. Online, even if other learners feel negatively about a statement, the learner writing the comment gets to complete the thought before someone else posts a reply. Plus, learners—at least in a print-based chat session—do not get the chance to see or hear each other during a chat. The impact of negative body language or censuring tone is missing from an online written chat.
Enhancing student-to-student and faculty-to-student communication:
The integration of online, web-based learning with proven education methodologies provides substantial added value to traditional education. Students and faculty can both benefit from using the communication and assessment tools that are made available via online learning.
Accessibility:
Attend online classes from anywhere.
Choices:
Take courses in different subject matters.
Communication:
The ability to communicate and interact with students all over the country or even the world.
Availability:
Documents, transcripts, live discussions and training materials are all archived and recorded so that they can be retrieved via mail, e-mail or the school’s website for reading, downloading, and printing. Instructors are also available at convenient times and respond quickly through email.
DISADVANTAGES
Alongside the advantages of the Online Distance Education there are also some downsides. The major disadvantages of Online Distance Education include access to technologies, a higher cost of running online courses than people originally envisaged, the inability to receive technical advice and perhaps the most damaging of all, the negative attitude held towards online distance education by lecturers, administrators and even some students.
Here are some disadvantages listed:
Progress:
With an online education, there is probably no one checking your progress on a regular basis. You may be given some guidance along the way, but you and you alone are usually responsible for working your way through the course.
Oral Communications:
Due to interaction through email or text chatting, individuals may not have a chance to enhance their oral communication skills.
Lack of skills in technology:
Many of the lecturers and administration officials connected with online distance education programs are unfamiliar with the technologies themselves
High running cost:
The cost of simply running appropriate computer systems and an Internet connection is expensive enough let alone when students have to pay for other multimedia material. Many of the new technologies are not cheap and even if they are cheap to distribute they may involve a large cost for the production of & equipment used to produce the item.
Employment:
Not all work industries acknowledge online degrees.
Fraud:
Many online degrees are not valid or accredited.
Courses:
Not all courses are available online.
TARGET AUDIENCE
The Internet is a powerful and popular medium for information exchange. Because of its 24-hour accessibility, people who are not able to attend a traditional college or university can obtain an education from a distance easier than ever before, and at their own pace.
In the past, working adults weren't able to further their careers because of time restraints; including, but not limited to, working overtime, business travel, and caring for families. Online education takes away those time restraints by offering a completely virtual learning experience.
Working adults can now continue their education, earn higher degrees, and earn more money by attending courses that primarily take place over the Internet. Therefore, online education is for the adults and for those who can’t built their careers by attending a traditional college or university because of time restraints, though advantages of this service can be taken by anyone who have computer with internet connection.
FITNESS FOR PURPOSE
According to recent reports, roughly one in six students enrolled in higher education – about 3.5 million people – took at least one online course last fall ( 2005 ) . This is double the number who reported doing so in 2002. Five Years of Growth in Online Learning, reported a 10 percent increase in popularity for the cyber classroom.
A Survey in United States
The Sloan Survey of Online Learning, “Making the Grade: Online Education in the United States, 2006,” shows that 62 percent of chief academic officers say that the learning outcomes in online education are now “as good as or superior to face-to-face instruction,” and nearly 6 in 10 agree that e-learning is “critical to the long-term strategy of their institution.” Both numbers are up from a year ago.
Researchers at the Sloan Consortium, which is administered through Babson College and Franklin W. Olin College of Engineering, received responses from officials at more than 2,200 colleges and universities across the country.
The Sloan report shows that about 80 percent of students taking online courses are at the undergraduate level. About half are taking online courses through community colleges and 13 percent through doctoral and research universities, according to the survey.
E-learning has come full circle
An electronic page is miles apart from a textbook. The challenge for e-learning portals is in making their Web pages as, or more effective than textbooks. This is done by making the "virtual course interactive, with chat and other software to make learning a real experience"
E-learning has indeed become an essential component of the learning process, rather than an independent and isolated tool. As a result, experts maintain there's been a noticeable trend amongst post-secondary institutions towards including facets of e-learning in their curriculums.
"E-learning was initially viewed as the be-all and the end-all," Mr. Van Wingerden, vice-president of learning solutions for Perth-based dominKnow, told , "but it has come full circle."
"People have really started to understand the fundamentals as well as the limitations. E-learning can give you a really strong base," Mr. Van Wingerden said.
HOW THE SERVICE CAN BE IMPROVED?
Improvement is needed in the following sectors:
* Although online distance education is supposed to reach an unprecedented learning audience the number of these students with access to the required technology is relatively low. So, improvement is needed in this sector.
* The online programs are great; however, the actual means of accessing the information are missing in a lot of communities. People who live in regional areas rarely own computers that are able to run all the new technologies. The major reason why this is so, is because of the high costs of the computer and the cost of Internet access. This high costing should be cartel down.
* Another major setback to the new online distance education system is the current lack of skills by students in using the new technologies. The online student’s has to acquire the kind of necessary knowledge and understanding about new technology.
* Many online education syllabus writers aim to have their education programs work in conjunction with new technology and to do this the teachers must pre-empt what technological changes are going to be made before the time of release of the course material. This leaves plenty of space for incorrect assumptions of what will be available.
* One of the most common thoughts from many institutions is that, just by using an online system to deliver the course, that it will simply just make the course better. More needs to be done than simply making the course available online to make the course a success.
* Teachers should Know the technology they are using! Be very comfortable with it — it will make their life easier and students will rely on them for assistance.
* Teachers should know their audience so that they can design in appropriate questions and interactions. Know your participants’ names and use them! Ensure that content is fresh and relevant to their needs. Be aware of what learners might not be aware of.
* Institutes should plan the course carefully and make sure that it has enough flexibility. Set clear expectations. Use a syllabus or outline to manage student expectations about institutes response time for individual emails, and define student participation so that students know there is a reward for quality as well as for a minimum number of postings.
* Institutes should send out lots of preparation information to make sure attendees are comfortable in their environment.
NON-ICT SOLUTION
Some of the non-ict solution of e-learning is listed below:
* Traditional method.
* In rural areas, some educated people teaches children where there is no school.
* Private tutor.
* Coaching centre.
* Language / speaking club.

COMMUNICATION
COMMUNICATION
Communication is the exchange of thoughts, messages, or information, as by speech, signals, writing, or behavior.
Communication through internet is a great blessing. Not only can people just talk to each other but they can also see each other. Communication made the world smaller and the people closer together.
Basically, there are 3 types of communication:
Written,
Verbal, and
Non-verbal.
Written includes letters, emails, memos, reports and formal documents. Verbal communication includes "chats", presentations and voicemail! Non-verbal communication is using signals to communicate and studying body language.
The Internet provides various ways of communication depending on the need and availability of hardware/software. These include e-mail, phone, instant messaging or IM, short message service or SMS, video conferencing and Web conferencing.
THE TARGET AUDIENCE
Log on to the Internet any day of the week, any time of the day, and find people-thousands of them-pouring their hearts out to perfect strangers. Turning to others about whom we know nothing, to people we can't see, hear, or touch-certainly never intend to meet-for solace, advice, and reliable information about issues closest to our hearts defies conventional predictions of social science. Not everyone can communicate through internet. Peoples who have computer with internet connection can use this service. Day by day number of users of this service is increasing at a high rate. Now, we can even use this online communication using our cell phone. Communication through e-mail is very popular to everyone nowadays. IM , chatting, blog etc. earned popularity among the youths. However, online communication is for all people, religion and culture. The main target of online communication was to bring people all around the world closer together. Therefore, this online communication service is equally important for all those people who have computers with internet connection and knows how to operate it!
SOME EXAMPLE OF ONLINE COMMUNICATION
Blog
Blog is a personal or business online journal or diary shared over the web. Usually it is maintained by an individual, with regular entries of commentary, descriptions of events, or other material such as graphics or video. Publishing of a blog is "blogging". Entries in blog are called posts. Blogs are frequently updated and entries in the blog are arranged in a chronological order.
Many blog provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, images, and links to other blog, Web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of many blog. Most blog are primarily textual, although some focus on art (artblog), photographs (photoblog), sketches (sketchblog), videos (vblog), music (MP3 blog), audio (podcasting), which are part of a wider network of social media. As of December 2007, blog search engine Technorati was tracking more than 112 million blog, this shows how popular a blog is.
There are many different types of blogs, differing not only in the type of content, but also in the way that content is delivered or written:
* Personal Blogs
The personal blog, an ongoing diary or commentary by an individual, is the traditional, most common blog.
* Corporate Blogs
Blogs, either used internally to enhance the communication and culture in a corporation or externally for marketing, branding or public relations purposes are called corporate blogs.
* Question Blogging
It is a type of blog that answers questions. Questions can be submitted in the form of a submittal form, or through email or other means such as telephone or VOIP.
E-mail
Electronic mail, often abbreviated to e-mail, is a store-and-forward method of writing, sending, receiving and saving messages over electronic communication systems. Electronic Mail is where a message is converted to electronic signals and sent from any workstation via a telecom network. The term "e-mail" applies to the Internet e-mail system based on the Simple Mail Transfer Protocol, to network systems based on other protocols and to various mainframe, minicomputer, or internet by a particular systems vendor, or on the same protocols used on public networks.
E-mail messages are usually encoded in ASCII text. However, send non-text files can also be sent, such as graphic images and sound files, as attachments sent in binary streams. E-mail was one of the first uses of the Internet and is still the most popular use.
E-mail can be distributed to lists of people as well as to individuals.
E-mail can now also be used on our mobile phones using GPRS, WAP or SMS.
An email system usually allows to:
* see a list of messages in our mailbox, showing the sender’s name, email address, the
subject of the message, and the date and time it was sent.
* select individual message to view.
* compose messages with a subject heading and textual content, and sent them to any
other e-mail address.
* send same message at the same time to different e-mail address.
* add attachment to mail and save attachment from mails.
Mail client and Mail server
An email client is a program run by a user to send and receive email. It retrieves all email for its user from the mail server to which it is connected. It sends all mail from its user to the same mail server, for the distribution to other users of email on other servers. The server therefore manages the communication of mail between internet domains ( such as hotmail.com and yahoo.com).
Advantages
# speed.
# reliability.
# convenience.
# weightless, no paper needed.
# Does not depend on the simultaneous availability of both parties ( sender and receiver )
because messages can be stored or forwarded and retrieved from any workstation.
Disadvantages
# set-up cost can be high
# still not generally available
# risks of data security
# computer can be virus effected through email
IM- INSTANT MESSAGING
"IM" – short for “instant messaging” – is a type of real time communication service. It is somewhat like email, but much more like a chat room. Both parties are online at the same time, and they "talk" to each other by typing text and sending small pictures in instantaneous time.IM is based on special small programs that two separate people install, and those programs connect to beam typed messages to each other. This special software allows peoples to "talk" online with thier friends in other rooms, other cities, and even other countries. The software uses the same cables and network as any web page or email connection.
There are varying levels of IM sophistication. Some IM products are bare-bones (example: Google Talk). User can simply send text messages only. Other IM systems offer advanced options that let them do more than send text messages. It is possible to share photos, send and receive computer files, carry out web searches, listen to the Internet radio stations, play online games, share live video (requires webcam), or even place free PC-to-PC calls worldwide if you have the speaker-and-microphone hardware.
History
The first IM’s were developed in the 1970s and allowed users to send text-based messages to computers linked on the same computer network, typically within the same building. Today, users can enjoy sending text-based IM’s, video and audio feeds and play video games online with their friends and family.
How Does IM Work? Once a user signs in to their IM client, the application sends and receives information from its dedicated server to display the availability of IM contacts for both that user and friends on their contact list. Using an individual users’ IP address and port number, clients then connect users directly once an IM is sent.
Merits
Multiple people may participate in the discussion. This allows on-line meetings to be held by people who may not be in the same country/office or room. When participants leave the discussion, they can receive an email containing a full transcript so that they know what decisions were made.
Some organizations do legitimately use this social tool to communicate, like receptionists talking to their bosses on-screen while simultaneously speaking on the phone. Factory workers who wear ear protectors can see on their screen when their supervisor needs them on the other side of the factory floor.
For teenagers, IM is a way to break boredom in the school computer lab...provided, of course, that the teacher doesn't shut down the IM connections in the room.
Demerits
It steals a lots of time
Teenagers gets effected and waste a lots of their valuable time
Many companies do forbid employees from using IM because it can be such a distraction to employees. Thousands of people every day steal time away from work to chat with their friends and co-workers on their screens.
Chat
Online chat is a way of communicating by sending text messages to people in the same chat-room in real-time. On the Internet, chatting is talking to other people who are using the Internet at the same time you are. Usually, this "talking" is the exchange of typed-in messages requiring one site as the repository for the messages (or "chat site") and a group of users who take part from anywhere on the Internet. In some cases, a private chat can be arranged between two parties who meet initially in a group chat. Chats can be ongoing or scheduled for a particular time and duration. Most chats are focused on a particular topic of interest and some involve guest experts or famous people who "talk" to anyone joining the chat. (Transcripts of a chat can be archived for later reference.) Some chat rooms such as Yahoo! use both text and voice simultaneously. There are also graphical user interface (GUI) text-based chat rooms which allow users to select an identifying icon and modify the look of their chat environment. Some visual chat rooms also incorporate audio and video communications, so that users may actually see and hear each other.
Videoconference
Videoconferencing is a conference between two or more participants at different sites by using computer networks to transmit audio and video data. For example, a point-to-point (two-person) video conferencing system works much like a video telephone. Each participant has a video camera, microphone, and speakers mounted on his or her computer. As the two participants speak to one another, their voices are carried over the network and delivered to the other's speakers, and whatever images appear in front of the video camera appear in a window on the other participant's monitor. Multipoint videoconferencing allows three or more participants to sit in a virtual conference room and communicate as if they were sitting right next to each other.
ADVANTAGES OF THE SERVICE
computerized electric telecommunications have created a global village in terms of the immediacy within which people across the world can share conversations, televised pictures, and interactive software on VDU’s, maps, graphics, and circuits. The process of making decisions has also increased in speed due to the instant access information’s.
Due to the electronic technology, jobs, working locations and cultures are likely to change. The term ‘telecommuting’ is already being used for people who work from home, who are linked to the office by modem and computer terminal, can access world wide communication links without even having to move from their desk.
Some advantages of online communication is listed below:
Gone are the days when people had to wait weeks or even months to receive postal mail! With the communication through internet, an email can be sent and reach its destination instantaneously! E-mails have made the world a smaller place, allowing people separated by great distances to correspond.
Instant Messaging, Chat Rooms – Services such as AIM, Yahoo Messenger, MSN Messenger, and Skype allow people to send messages instantaneously, much like a phone conversation, but using written messages.
There are also “virtual rooms” on the internet facilitated by services developed for this reason. These “rooms” allow many users to chat using written messages.
People can communicate with each other from anywhere in the world.
People can communicate while they are in a journey.
Busy business persons can do official work in their home and at the same time give valuable time to his/her family.
Businessmen can communicate with their clients or their employees sitting in his/her bedroom.
Data is transmitted at electronic speeds, rather than by mail and other relatively slow methods.
Data can be collected, and information disseminated, very quickly.
Operating cost is reduced. Data communication can replace mail and courier services and can often eliminate the need for meetings and conferences. A company with data communication has the choice of processing the data centrally.
People can communicate from his/her home, no necessary of physical appearance.
feedback exchange (Computerized telecommunications allow for a virtually simultaneous exchange of information and responses).

Gone are the days when people had to wait weeks or even months to receive postal mail! With the communication through internet, an email can be sent and reach its destination instantaneously! E-mails have made the world a smaller place, allowing people separated by great distances to correspond.
Instant Messaging, Chat Rooms – Services such as AIM, Yahoo Messenger, MSN Messenger, and Skype allow people to send messages instantaneously, much like a phone conversation, but using written messages.
There are also “virtual rooms” on the internet facilitated by services developed for this reason. These “rooms” allow many users to chat using written messages.
People can communicate with each other from anywhere in the world.
People can communicate while they are in a journey.
Busy business persons can do official work in their home and at the same time give valuable time to his/her family.

DISADVANTAGES OF THE SERVICE
The amount of face to face oral communication, across the office desk or around tables will also decrease because of computer based videos, telephone or computer screen hook ups. Many types of fraud exist, and email is an inexpensive and popular method for distributing fraudulent messages to potential victims. Most fraud is carried out by people obtaining access to account numbers and passwords. Some of the most common fraudulent messages are non-monetary hoaxes or non-monetary chain mail.
