|
Principles for determining relevance of technology
Objectives
|
At the end of this unit you should be able to:
- apply relevant principles to determine the most appropriate mix of media and technology in the design and delivery of ODL courses.
|
Overview
It is important to realise that media and technology do not necessarily differ in their effectiveness. They all have very peculiar strengths and limitations. However, a particular subject or topic may lend itself to a particular medium. Media and technology is primarily used for two purposes in the context of Open and Distance Learning (ODL), namely: to distribute learning content to learners; and to stimulate and support learning by means of one-way or two-way communication.
Our basic aim as educators should therefore be to determine the most appropriate mix of media and technology for a given learning outcome. The following principles and questions should guide decision-making in this process.
| Principle |
Description |
Guiding Questions |
|
Learner profile
|
media and technology need to fit with learners' needs and realities
|
- How do they learn?
- What are their motivational levels?
- What learning difficulties do they normally face and how can technology be used to address this?
- Do they have access to the required technology? If not, will they be able to acquire it?
- Is there a distribution issue?
- Do they have skills to use the technology?
- Do they have relevant prior learning?
|
|
Curriculum and Type of Material
|
media and technology need to be appropriate for the curriculum and for teaching effectiveness
|
- Is the content structured or unstructured?
- How immediate is the need since development of structured content is generally time-consuming and more costly?
- Will delivery be synchronous or asynchronous?
- What is the lifespan of the course materials?
- What is the size of the audience?
|
|
Capabilities of the media and technology
|
media and technology should match the needs of the learners
|
- Is this the most appropriate technology to achieve the learning outcomes?
- How proven is the technology?
- At what speed can it be updated/replaced?
- How difficult/costly will it be to maintain the technology?
- Is there in-house capacity to maintain the technology or will it be outsourced?
- Does it cater for interactivity?
- Will the technology stimulate/motivate learners?
- Can it be used for feedback to learners?
- Will students be able to assess their progress?
|
|
Cost and time to produce content
|
media and technology must be affordable for the institution and the learner
|
- Do you have the time to produce the content?
- Can you afford the preferred development and delivery model?
|
|
Resources
|
essential resources should be available
|
- Do you have the necessary human, financial and physical resources to achieve this?
- Is special equipment required?
- Do staff need time to develop new skills?
|
Reflection
|
Remember, a careful blend of media and technology drawing on their individual strengths and minimising their individual limitations is likely to produce the best results. Try and find a balance between quality and cost!

Three Main Categories of Technology
Objectives
At the end of this unit the participants will able to:
- compare and contrast between print, audio/video and computer technologies
- determine the effectiveness and applicability of each these technology
|
This Chart depicts the manner in which the following information is presented.
Print
Objectives
At the end of this section the participants will able to:
- determine the benefits and limitations of print media
|
| Print Material |
Print-based courses, or 'correspondence courses' are perhaps the oldest delivery method for distance education courses, having been available to students and learners for well over 100 years.
The more traditional print courses are provided entirely on paper.Printed course book, course guide, letters, comments on assignments are some examples.
Print courses are usually delivered via the mail, but some also have email or fax options to enhance communication between student and instructor.
|
| Advantages |
Disadvantages |
Guidelines for Incorporation |
- Extremely portable
- Comfortable
- Cost effective
- Readily
|
- Lacks interactions
- No audio/visual elements
- Require reading skills
- Time delay
|
Tips:
- Distribute print materials well in advance
- Include clear directions for use
- Require interactions
- Specify a timeline
|
Audio/Visual
Objectives
At the end of this section the participants will able to:
- identify the strengths and weakness of audio/visual media
- determine the scope and effectiveness that audio/visual technologies afford
|
Audio Technologies
| Audio Technologies |
Audio is often thought of as the most important part of any kind of teleconference.
Audioconferencing is sometimes considered a conference call, but with many optional features available and an almost limitless number of individuals being able to simultaneously participate in the same event. It is an easy, economical way to bring many people together to meet, learn, and teach.
Basic technology needs is simply a telephone.
|
| Advantages |
Disadvantages |
Guidelines for Incorporation |
- Inexpensive
- Easily accessible
- Easy to use
|
- May require scheduling
- Not conducive to visual information
- May be impersonal
|
Tips:
- Distribute visual materials in advance
- Set communication protocols
- Encourage interaction
- Record audioconferences on audiotapes
- Get to know the students
|
Video Technologies
| Video Technologies |
Interactive videoconferencing allows students and faculty at multiple locations to see, hear, and interact with one another.
|
| Advantages |
Disadvantages |
Guidlines for Incorporation |
- Allow both audio and video communications
- Facilitate personal feelings
- Enable high levels of interaction
|
- May be expensive
- Require a great deal of planning and preparation
- Must be scheduled
- Require technical support team
|
Tips:
- Avoid the "talking head."
- Practice with the cameras and the crew before the lesson
- Encourage interactions
- Use the best cameras possible
- Ensure quality audio
|
Computer Technologies
| Computer Technologies |
- Computer Disk/CD-ROM/DVD
- Some classes are offered on computer disks, CD-ROMs, or, more recently, DVDs. You need access to a computer to view the course materials.
- IHETS Interactive
- IHETS Interactive [1] is a Web-based application that supports live video and audio as well as other types of interaction and collaboration. Students watch and listen to the instructor using a standard Windows PC and interact with the instructor and one another using the application’s audio and text chat features. IHETS Interactive classes can be taken at any location with a networked PC meeting the minimum technical requirements, including from home or work.
- Internet
- Courses delivered over the Internet often, but not always, use the World Wide Web. They may include material to read online, exercises to complete online using interactive forms, discussion forums to exchange ideas with the professor and other students in the class, and many other types of instructional activities. Students can participate from any computer with an Internet connection.
