The advantages and disadvantages of multimedia

There are a couple of advantages and disadvantages to using multimedia in communication. I’m only going to a list a few important ones below. If you are interested to know more, visit one of the given websites by just following the links.

Advantages:

It is very user-friendly. It doesn’t take much energy out of the user, in the sense that you can sit and watch the presentation, you can read the text and hear the audio.

It is multi sensorial. It uses a lot of the user’s senses while making use of multimedia, for example hearing, seeing and talking.

It is integrated and interactive. All the different mediums are integrated through the digitisation process. Interactivity is heightened by the possibility of easy feedback.

It is flexible.Being digital, this media can easily be changed to fit different situations and audiences.

It can be used for a wide variety of audiences, ranging from one person to a whole group.

Disadvantages:

Information overload. Because it is so easy to use, it can contain too much information at once.

It takes time to compile. Even though it is flexible, it takes time to put the original draft together.

It can be expensive. As mentioned in one of my previous posts, multimedia makes use of a wide range of resources, which can cost you a large amount of money.

Too much makes it unpractical. Large files like video and audio has an effect of the time it takes for your presentation to load. Adding too much can mean that you have to use a larger computer to store the files.

In case you want to upload it onto the Internet, there are a few factors to keep in mind, for example bandwidth and the user’s abilities.

Here are a few websites with more information:

Using multimedia in the classroom introduces students to video and audio sources.

What Are the Benefits of Laptops for Students?

Multimedia in the classroom has evolved rapidly with a progression from audio cassettes to internet sites in classroom learning. Examples of multimedia in the classroom include the use of video, the creation of video by students, the creation of spreadsheets or the development of a website displaying student work.

Practical Advantages to Using MultimediaA major advantage to using multimedia sources in the classroom is the ability to bring in images, sounds and videos without leaving the room. Computer programs and internet sites can also give students experiences that might ordinarily be unsafe, such as views from scaling mountains in a geography lesson or a dissection of a rare animal. Additionally, using a projector or individual computers gives students the opportunity to view information or materials up close.

Educational Advantages to Using MultimediaStudents who learned from materials containing both text and graphics produced 55 percent to 121 percent more accurate solutions to problems, according to David Taylor at the University of Maryland. The use of images, along with words, diminishes the overwhelming nature of text and helps the student to manage the cognitive load, which increases retention. Specifically, graphics are found to support retention because important elements are focused on via placement, layout and color. Activation of prior knowledge is engaged quickly with visual analogy, and mental models are created easily as diagrams can enhance understanding of how a concept works. Additionally, learning is made easier because simulations allow students to visualize real-life situations, and motivation is increased as students are able to see the relevance of skills.

Practical Disadvantages to Using MultimediaMultimedia lessons or components of lessons delivered via video or image require computers, projectors and other electronic devices depending upon the subject and the amount of original material a teacher creates. The expense associated with quality projectors or computers for every student can be quite high, and the amount of images and videos in a lesson can slow down the delivery and pace of the class as a result. Student access to computers at home may also cause problems, and varying quality of student electronic devices can create inequity in projects and presentations.

Educational Disadvantages to Using Multimedia

When designing a multimedia learning experience, the role of the teacher shifts from instructor to facilitator. If a lesson allows students to complete learning at their own pace as they move through stages of learning, classroom management becomes increasingly difficult. This is particularly true if students work in groups to view multimedia sources or share computers. Additionally, students who are not as proficient with technology may have to spend more time learning computer skills to access information than focusing on course materials.

Disadvantages of Using Multimedia in Professional Communicationby Bridgette Redman, studioD

Modern technology makes multimedia a tempting tool.

Multimedia can be an exciting addition to business communication. Its flashiness and fun holds great temptation for the business communicator who wants to add pizazz to presentations, business plans or even memos. However, giving in to this temptation doesn't always produce the desired results. Using multimedia effectively can be tricky business and sometimes the old adage makes the best rule: Simple pictures are best.

Equipment FailureMultimedia often requires more equipment to deliver a message than more traditional mediums. Whenever equipment is involved, there is the chance that the equipment will fail. Time is a precious commodity and you don't want to spend time with your customer, client or business associates trying to fix presentation equipment, change a light bulb, get a new computer or search a hard drive for a missing multimedia file.

Message Distraction"The medium is the message," stated the noted communications expert Marshall McLuhan. This is great if you're selling media, but not so great if you're trying to communicate on other topics. There is a danger when using multimedia in business communications that the focus because the medium, the multimedia presentation. If this distracts from your message, then you've spent a lot of time, energy and money on failed communication. Make sure that any multimedia you incorporate supports the message and isn't just included for the sake of looking technology savvy.

Lost ProductivityEven with software making multimedia easier than ever to develop and incorporate into messages, it still takes time. Consider how much time you will spend figuring out the software, collecting images and sound bites and putting them together in a professional looking presentation. Then compare that to the rate of return you expect from the message and evaluate whether the time is well spent. Too much time incorporating multimedia into professional

communication when a simple message would be just as effective translates into lost money and lost productivity.

Multimedia QualityThe quality of the multimedia you use in your professional communication will say something about your company. Given that multimedia clips can vary greatly in quality, you may be sending the wrong message inadvertently. Throwing together a bunch of unrelated images or poorly recorded sounds can be annoying to those receiving your message. On the other hand, high-quality multimedia can be expensive to create or purchase.

Ethics

Information technology ethics is the study of the ethical issues arising out of the use and development of electronic technologies. Its goal is to identify and formulate answers to questions about the moral basis of individual responsibilities and actions, as well as the moral underpinnings of public policy.

Information technology ethics raises new and unique moral problems because information technology itself has brought about dramatic social, political, and conceptual change. Because information technology affects not only how we do things but how we think about them, it challenges some of the basic organizing concepts of moral and political philosophy such as property, privacy, the distribution of power, basic liberties and moral responsibility.

Specific questions include the following. What are the moral responsibilities of computer professionals? Who is to blame when computer software failure causes harm? Is computer hacking immoral? Is it immoral to make unauthorized copies of software? Questions related to public policy include: what constitutes just policy with respect to freedom of speech, association, and the exercise of other civil liberties over computer networks? What

determines the extent and limits of property rights over computer software and electronic information? What policies adequately protect a right to privacy?

The list of questions shifts in response to developments in information technology. One noteworthy example is the rise in prominence of questions about communication and information in response to the explosive growth of high-speed digital networks. This shift has subsumed the field commonly called ‘computer ethics’ under the broader rubric of ‘information technology ethics’.

Analysis of the Advantages and Disadvantages of Multimedia Teaching in Colleges LI Baoping1

, WANG Yan2

1. College of Computer Science & Technology, Henan Polytechnic University, Jiaozuo, Henan, P.R.China, 454003 2. Wanfang College of Science & Technology HPU, Jiaozuo,Henan, P.R.China libaoping@hpu.edu.cn Abstract:The teaching method of using multimedia equipments in class improves teaching quality and efficiency, accelerating teaching reform in universities and colleges. However, sometimes it even harms the teaching effect. By doing surveys in four universities in Jiaozuo, and analyzing the advantages of using multimedia, this paper points out the problems in current teaching method and offers some suggestions and countermeasures. Thus multimedia technology could wield its magnificent power in education. Keywords:teaching method, abuse, multimedia teaching, disadvantages1 Introduction As the development and spread of computer technology, most colleges and universities begin to use multimedia in teaching because it can present not only words, but also graphs, pictures, sounds, even motion pictures and videos[1]

. However, this teaching method has not been properly employed in class, inducing declining in teaching efficiency. This essay analyzes current situation of teaching in four colleges in Jiaozuo (Henan Polytechnic University, Jiaozuo Teachers’ College, Jiaozuo University, Wanfang College of Science and Technology), pointing out existing problems and causes of these problems, and also offering measures

to solve these problems, to speed up development of multimedia teaching methods and up-grade teaching efficiency. When using multimedia teaching method in class, we must plan the whole teaching procedure, choosing the proper multimedia equipment, and combine the traditional teaching methods. Thus we can optimize teaching process, achieving best teaching effect[2]

. Multimedia teaching method was developed in 1980s, which can also be called computer assisted instruction (CIA). CIA uses computers to manipulate and control signals, languages, sounds, pictures, videos and other information and shows these on a screen by projector with coordinated sounds. Users control the computer to finish the whole teaching process[3]

. 2 Advantage of Multimedia Teaching Method 2.1 Arousing students’ interests Multimedia teaching method fuses writing, sounds, picturesand videos together, making teaching contents easy to understand and heightening class atmosphere. Thus it arouses students’ enthusiasm. 2.2 Better emphasizing key and difficult points in teaching When using multimedia teaching method, teachers can make useof different colors to increase students’ interests, show pictures of things that students cannot imagined, and deliver more and specific knowledge and information to students through sounds and videos. 2.3 Improving teaching efficiency by adding more information in class Multimedia teaching makes use of different equipments in its teaching process, adding more information to the class and benefiting teaching quality and efficiency[4]

. M & D FORUM 2653 Existing Situation of Multimedia Teaching Method Results of surveys conducting in four universities in Jiaozuo: 3.1 More utilization rate of PPT, less utilization of other functions After observing the teaching procedures in four universities, we find that more than 80 percent of

teachers use PPT made by themselves in class. The contents of PPT are all texts which are the same as what we write on blackboard in traditional way of teaching. They seldom use other functions and there is no flexibility in teaching so it’s hard for students to focus in class, thus lowering teaching effect. 3.2 Most of PPT just copy textbook The contents of most PPT are from textbook. The teachers just transfer the same information from textbooks to PPT, which doesn’t differ from traditional way of teaching and doesn’t fully utilize multimedia equipments. 3.3 Dependent on PPT in teaching After utilizing of PPT, teaching process becomes reading the textbook or PPT. Teachers all use PPT in class, teaching becoming reading. Teacher-oriented changesinto PPT-oriented. PPT becomes center of teaching. If the multimedia equipments, especially computers and projects, break down, teachers can not smoothly finish the teaching procedure. 3.4 Q ualities of PPT Most teachers make PPT by themselves. However, few teachers download PPT from the internet or acquire PPT from other resources. These teachers are not familiar with the contents on the PPT, so once the computer breaks down, class cannot conduct properly, compromising teaching quality. 4 Abusing Multimedia Teaching Method 4.1 Teaching process quickened by multimedia equipments Teachers don’t have to write on blackboard when using multimedia equipments, which on the one hand, saves much time. On the other hand, it causes disadvantages. Most teachers cannot control rhythm of class, quickening teaching process. Thus students are passively led by PPT and cannot think actively in class. 4.2 Foster laziness among teachers Many teachers use the same PPT when teaching the same lesson. They don’t change contents on PPT according to students’ reaction and pay no attention to explore teaching patterns. In the long run teachers become lazy and don’t fully prepare for every class. 4.3 Lack of communications and interactions between students and teachers After introducing multimedia equipments into class, someteachers just sit behind the computers and

play the PPT. Students can only hear teacher’s voice butcannot see the person. Therefore, students cannot communicate with teachers. Because of lack of interaction, teachers don’t know students’ reaction and cannot control teaching procedure. Thus, throughout the whole class, teachers talk with no enthusiasm, and students listen without passion, compromising teaching quality. 4.4 Harm students’ creativity If teachers just sit behind computers and don’t communicate with students to lead them to think and evoke their thoughts, it will harm students’ creative thinking ability. 5 Countermeasures
