All Interactive Whiteboard systems have a number of requirements in common. They are:
  1. A projector or television-type display
  2. A software interface, almost always residing on a computer
  3. A means by which digital content moves from computer to/from the projected or transmitted image, often a USB cable
  4. A surface on which content is displayed. It can be a touch-sensitive board or a surface such as a wall
  5. A means of writing on or manipulating content on the "board" or other surface. May be an electronic pen or stylus or it may simply be the user's fingertip

There are usually two software components on the attached computer:
  1. A "driver" (allows communication between the device and the computer), e.g. SMART Tools
  2. Annotation or "notebook" software that provides the actual writing interface for the system. Often there is an entire suite of software tools, e.g. SMART Notebook and Tools
If the Interactive Whiteboard is a traditional model (as seen above top), the user writes on an actual touch-sensitive board using simple plastic stylus pens or the user's finger.
If the system uses an Interactive Projector (above, bottom), the "board" functions are assumed by the projector itself which communicates via wireless connection with an electronic stylus in the hands of the user. In this case, a touch-sensitive board is not required.
List of the Advantages of Technology in Education

 


1. Promotes independent learning in students
The internet is a treasure trove of information. Practically anything you need to know can be found online. Although there is a question of the credibility of the source and the data provided, it can still serve as an educational resource for students. Even without assistance from parents and teachers, students can just look up their lessons online.
Unlike regular textbooks, electronic books and web-based content are updated in real time, feeding students with the most current information they can get their hands on, helping them become more knowledgeable even outside the classroom setting.
Prepares students for the future
From the way technological advancements are going, it is obvious that the future will be digital and technology-focused. If students are well-versed on using technology to collaborate and communicate as early as now, they will not have trouble fitting in, competing and finding jobs in the future. Being familiar with using at least one form of technology at an early age will help them become comfortable using it, and eventually develop other skills necessary to handle other innovative devices and processes.
3. Has the potential to lower textbook and tuition prices
With resources more accessible and in great abundance, the cost of textbooks is likely to decrease. It is also possible that students may no longer need to buy a textbook, if it is converted into digital format. The actual books can stay in the classroom, while the content is saved on a student’s computer.
Tuition will also decrease when learning is done online, rather than inside the classroom. By taking out the factors that contribute to a higher tuition fee, such as utility bills and transportation allowance of teachers, the overall cost of education will be lower.
4. Allows teachers to create an exciting way to educate students
Gone are the days when the only tools for teaching are limited to books, a blackboard or whiteboard, and a chalk or markers. With technology integrated to education, teachers can now incorporate images, videos and other graphics when delivering lessons. Specific websites, apps and programs will also enable teachers to vary how they provide instructions. This creates an exciting learning environment and promotes interest in education in general.
Other tools available for teachers include Smart Boards (interactive whiteboards), email Skype, and PowerPoint.
5. Encourages development of new teaching methods
Rather than spend an hour or so talking while the students listen, or have them read an entire chapter in silence, teachers and professors now have the option to use advanced teaching methods, such as podcasts, blogs and social media. When working with a particular group or one-on-one, teachers can take advantage of web conferencing technologies other online communication tools.
Technology also presents universal tools that enable teachers to educate all types of students, including those who are struggling or have special needs. These include voice recognition, text-to-speech converter, translator, volume control, word prediction software and other assistive technologies.

List of Disadvantages of Technology in Education

1. Results in a lack of interest in studying
Because everything is now accessible online or through data saved in a computer or mobile devices, students are likely to develop poor studying habits and a lazy attitude towards education. Some of them may even think they can skip school because they can find answers and lessons online. Who needs teachers when you have internet and Google, right?
This can also lead to students forgetting the basics of studying. They would rather rely on computers and the internet, instead of their books and the input from their teachers. Most of them will misspell words because they often use spell checkers. Rather than solve mathematical equations the traditional way, they would seek assistance from computers or look for the answers directly through search engines. When it is time to take the tests in the classroom and without any form of technology, students are likely to fail.
2. Makes students vulnerable to potential pitfalls
While computers prove to be an invaluable educational tool, it can also be a source of problems. This is especially true for students who lack the skills needed to maximize a device’s functionalities. Technical problems and computer malfunctions can cause loss of assignments and other materials, resulting in high levels of stress that students would rather not experience. Difference in internet speeds and a device’s capabilities can also lead to certain difficulties that will de-motivate students. Add to this other things that they will discover online, which are completely unrelated to school and education, and they will be distracted to no end.
3. Negative views on technology
Consumerism has taught us that technologies, from computers to mobile devices, are widely viewed as tools to entertain rather than educate. Textbooks, on the other hand, are seen as tools for learning. So, between a tablet and a textbook, students are likely to gravitate towards learning when reading a book, while they are likely to use a tablet to play games or spend time on social media.
4. Raise instructional challenges
For professors and teachers to stay abreast with technology, they may need to be retrained. Those who have been teaching all their lives using traditional methods may not be very susceptible to the changes being applied. They may even see it as a threat to their job security and shun technology altogether. In fact, a majority of teachers believe that constant use of digital technology is affecting a student’s attention span and his ability to persevere when a challenging task is thrown his way. Although such belief is subjective, scholars, experts and teachers all agree that technology has changed the way students learn.
5. Can diminish overall value of in-person education
Although research on online learning did not establish a direct link to how personal interaction affects a student’s performance, data gathered did show that those who enrolled in online courses have higher chances of failing, dropping out of classes, and are less likely to benefit from them. This may have something to do with the fact that lessons delivered online or through digital resources lack the face-to-face interaction between teacher and student that provides a more personal experience.

Conclusion

Integrating technology in education has its advantages and disadvantages, but proper implementation might help keep the drawbacks to a minimum. Better planning is necessary.

A video-conference has the following advantages:








video conference (video conferencing)
A video conference is a live, visual connection between two or more people residing in separate locations for the purpose of communication. At its simplest, video conferencing provides transmission of static images and text between two locations. At its most sophisticated, it provides transmission of full-motion video images and high-quality audio between multiple locations.
A video-conference has the following advantages:
bullet
It avoids the participants having to spend time travelling to meet each other.
bullet
Saves travel costs.
bullet
The participants in different locations are able to work on the same electronic document.
bullet
Seeing the person that you are communicating with can give important visual clues that are not available during a telephone conversation.
bullet
It can be used to allow an expert to investigate a problem without making a site visit, for example an engineer could view components that have failed so that the correct replacement parts can be supplied.

The disadvantages of video-conferencing are:
bullet
A high bandwidth communication link is required to transmit and receive high quality images.
bullet
There is a short time lag between speaking and receiving a response that can disrupt the natural flow of a conversation.
bullet
High quality dedicated video-conferencing systems are expensive to buy.

A video conference uses cameras and microphones to send images and sound across a network or the Internet so that two or more people can:
bullet
Communicate verbally while having visual contact with each other.
bullet
Collaborate on the same document.
