Skype or Hype
Learning through Skype?
However, Skype is not necessarily made for classroom type settings and this is quite apparent in its drawbacks. Skype works better for 1 to 1 or small group connections because it is hard to see and hear otherwise on the small computer camera and microphone. Skype would be hard to use in a lecture style class, unless none of the students asked questions. It would be very hard to ask a question to a professor over Skype because the microphone would not be able to pick up the noise form far away. The professor also would not be able to see the whole class, as the computer's camera cannot span an entire lecture hall let alone provide clear pictures. There are also times when Skype freezes up which would cause problems in a lecture, especially if the students are not able to inform the professor that they did not hear that last part. Skype has many limitations that do not allow it to be used very effectively for large group communication.

To Skype or Not To Skype
However, Skype is not all that practical in a classroom setting, if the school does not have the right equipment. One cannot just flip a computer screen around, which has a camera attached to it, and expect a classroom of students to easily communicate with the teacher. Most screens are too small, and even with a projector, there is only one microphone attached to the computer, which is only good for a few feet from the computer. Additionally, it is not necessary to use Skype unless the teacher is a reasonable distance from the classroom. Otherwise, using Skype would just create unnecessary communication difficulties.
Skype: The Up’s and Down’s
Unfortunately Skype has a few issues. While Skype is currently free to operate, there are several start-up costs. For instance, one must a microphone, a web camera, a computer with a fast processor, and a high-speed Internet connection. These costs make Skype too expensive for some people to use. Also, Skype does not work well in large groups. It is difficult to see and hear everybody in a large group with one web cam and one microphone. In addition, because of the large bandwidth Skype requires it has a tendency to freeze the computer and cause confusion and frustration. Regardless of these negatives Skype is a pretty useful tool, and is nice to have.
Skype In The Classroom
Teaching With Skype
Skype: For your viewing pleasure
Although Skype has many pros, the program had many negative aspects as well. The program is especially problematic in large groups. As demonstrated in our class, there were many technical problems with Skype. Skype froze many times and in order for our class to communicate we had to almost yell for the teacher to hear or understand us. Skype is a very good software for person to person conversation, but with use in large groups it is very difficult to coordinate. The start up costs of Skype are also troublesome. In order to use Skype, one needs to have a computer, preferably with a fast processor, and Internet, preferably high speed. In order to use the video and audio functions of Skype, one needs a webcam and a microphone. These start up costs and technical issues make Skype limited in its uses and functions; however, for the right purposes and groups, Skype can be very useful.
Pros and Cons of Skype
While Skype could be useful in education, it has drawbacks as well. It may be useful for professors to lecture through Skype, but it also gives them less control over their students. Since it is difficult for the professor to hear students unless they speak into the microphone, the professor would not know if side conversations were going on in the back, limiting knowledge from being gained. It is also difficult for professors to lead discussions through Skype. Therefore, Skype is best used for one on one communication.
Skype.. Not a lecture
However, Skype while useful in the inner workings of the business side of teaching, it simply cannot teach our lectures. Our own experience yesterday showed us that when the teacher tried the novelty of teaching through Skype, the result was a failure. What was the general response to being taught from a distance? We laughed at it. It was a joke and because the teacher was unable to actually be present and had only a limited view of what was going on, she lost the focus of her class. Then while being unable to fully see what was happening in her class, we could not effectively understand what tasks she was assigning.. How many times did we have to ask her to re-pronounce the words she wanted searched. Communicating over Skype was simply too accident prone to effectively use in teaching a class.
The idea of remote teaching has been bounced around for a long time now. The premise is a good one for the lazy. Why should I have to go to the classroom when I could stay home and teach from there? This was what inspired a Japanese company to try and create remote controlled "teacher" bots. But so far it is nothing more than a glorified version of the Skype lesson we experienced yesterday. How many teachers does it take to use Skype? It may take two teachers to control the classroom than just one: a teacher on the scene to make sure everything does not explode into anarchy and another to teach the lesson. Our teacher, meanwhile, was not even 50 feet away.
Skype is a wonderful tool and I use it everyday to talk to friends and collaborate on matters. But I cannot see the benefit from using Skype to teach from a distant position to a group of students who could use a actual authority in the classroom.
My Gripe with Skype
Although Skype is effective in a large classroom setting, it has its drawbacks in smaller classroom settings. Whereas in large lecture halls, there is minimal student-teacher interaction, smaller classrooms thrive on the ability for students to be able to interact with the teacher. If a teacher is present in the classroom, then the student will be able to pick up on key auditory and visual cues provided by the teacher, however many of these cues may not be picked up on Skype. This is primarily due to Skype’s unreliability and dependence on a working internet connection. As we witnessed in class on Thursday, there were several times where the screen froze up, which led to wasted time trying to fix it. In addition, communication over Skype depends on a microphone, so the only way that each student would be able to interact with the teacher would be if each student had his or own microphone. Although this could be solved by distributing a microphone and a webcam to each student in the class, it is not very cost effective, and it would be much easier for the teacher to just be present in the classroom. Another limitation presented by Skype is the lack of eye contact. Eye contact is a crucial skill for face to face communication, and if the student cannot tell if the teacher is specifically looking at him or her, or vise versa, then it is difficult to tell if the other person is actually paying attention. The teacher could easily be looking at something else on his or her computer screen rather than paying attention to the class, and the students would not even know. Due to the limitations presented by Skype within a small classroom setting, students receive much less personal attention, thus hindering the overall learning experience rather than improving it.
Teaching With Skype
The biggest drawback of teaching a class with Skype would be the risk of technical difficulties. While the sound issue in our class was rather minor, if the screen froze or the video cut out, then much of the benefit of Skype is lost. If the sound were to cut out completely, then it would be difficult to teach the class at all. And if the internet connection was down, then it would be impossible. The negatives of Skype are more the risk of failure rather than lack of functionality.
The Merits of SKYPE in the Classroom
Our class yesterday showed us that Skype is less than ideal when considering modes of education--the sound quality was iffy and the video feed had a tendency to skip and lag. But in a larger context, Skype can aid in the education of so many people around the world, especially those from disadvantaged areas of the globe. Skype opens up doors to many people that may not have the opportunity to commute to school, and provides a relatively cheap alternative for disadvantaged students. Yes, a student in a poorer country would need a computer, high speed internet access, and the like to sit in on an online class--but if classes were conducted via the internet, wouldn't foreign governments be more likely to spend on such necessary infrastructure as establishing said internet access? If classes were conducted online via Skype, a student from a third world country could potentially tune in at a very cost-effective rate.
As for those of us attending elite US universities like Michigan, Skype really doesn't hold much value. The ability to communicate with teachers is poor due to a lack of sound quality, and the lack of personal proximity and eye contact makes for a very detached lecture; one that won't resonate well with students who expect much more. Additionally, the cost of a University education is so high right now that I don't think students would accept being taught by Skype. It is way too impersonal and, at least to me, signals a lack of effort on the part of the teacher to make him or herself present to the class. Skype essentially takes away all accountability away from teachers and places the onus entirely on students to learn the material themselves, which I think is unfair, especially at such a high cost.
The Good and the Bad of Skype in the Classroom
While Skype is a great tool for simulating a traditional class, there are many reasons why it does not quite compete with the physical presence of a teacher. First of all, if a teacher is in the classroom he/she will have a much easier time controlling the class. By this I mean that it seems easier to take the teacher seriously if he/she is actually there than if he/she is just a talking face on the wall. Also, discussion in the classroom when the teacher is using Skype can be greatly limited, as we saw in our class on Thursday. This is due mainly to the fact that the teacher cannot hear what all members of the class are saying simply because they are too far away from the microphone, forcing students to get out of their seats and walk to the microphone. This is ineffective for two reasons, one because students are less willing to physically get up and talk into a microphone in front of the whole class than they would be to simply raise their hand and talk in a traditional class setting, and two because it takes a long time for one student to add one comment to the discussion when conducting class this way. A solution to this problem would be to distribute microphones throughout the classroom so that everyone's voice would be picked up, but this would be expensive and tedious. Another problem associated with using Skype to conduct class is its unreliability. The screen freezes quite frequently when using Skype if the Internet connection becomes too weak. This disrupts class and becomes a technical issue that should not have to be dealt with in the middle of class. Even though Skype is the best tool out there right now for conducting class without the physical presence of a teacher, it needs to be greatly improved before it can be considered equal.

What's all the hype about Skype?
To Skype or Not to Skype?
On the other hand, Skype does have its drawbacks. In a video conference on Skype, your experience will only be as good as your Internet connection. If your connection is slow or unreliable, your video conference will be fuzzy and inaudible or it may not work at all. In addition, it may be difficult for teachers to directly interact with students as they would in a classroom setting. For instance, a teacher would not be able to watch a student work on a math problem in real time. Sure, the teacher could review his work after he sends the file to him, but that is much less efficient than a teacher watching you work on it. Also, if students are using Skype, it is impossible for the teacher to monitor their attention. Whether they are watching the professor or playing a computer game, the students eyes will still be fixed to the screen.
There are numerous disadvantages to using Skype, but for those that do not have a traditional classroom experience available, it is far better than not receiving an education at all.
