Technologies for distance education can be categorized as either telecommunications technologies that connect instructors and learners, or classroom technologies that record and display instructional information. Effective distance education requires choosing the appropriate instructional technology based on learning outcomes and experiences, and matching each to the most suitable available technology. It also demands new skills from educators and learners in online classrooms.
2. TECHNOLOGIES
Technology is most noticeable used to promote
communication
Communication occurs when two or more individuals wish
to share ideas
Communication in distance education occurs when learners
interact with each other and the instructor
Language and culture and two thing in common that
communication and communication for distance education
have in common
3. COMMUNICATION MODEL
To communicate accurately instructional ideas are
encoded into some transmittable form, such as spoken
words, pictures and writing.
Effective communication must require an active
audience and media is used to communicate to distant
learners and the messages must be decoded
4. TAXONOMY OF DISTANCE EDUCATION TECHNOLOGIES
In distance education it is vital that educators think about how communication
can occur and how to apply experiences so it can promote effective and efficient
learning.
Several different methods can be used to show the experiences to students
Correspondence study: longest and simplest form of distance education
Prerecorded Media: incorporation of media into correspondence study system
5. TAXONOMY OF DISTANCE EDUCATION TECHNOLOGIES
Two-way audio: first widely used form of
distance education
Two-way audio with graphics: an embellishment
of the two-way audio form
One-way live video: Referred to as broadcast
distance education.
6. TAXONOMY OF DISTANCE EDUCATION TECHNOLOGIES
Two-way audio, one-way video: telephone system with 800
number
Two-way audio/video: normally called the compressed video
often used in conference calls
Desktop two-way audio/video: multimedia computer, camera,
microphone, high-speed network connection
7. CATEGORIES OF DESKTOP AUDIO AND
VIDEO
Analog systems are using telephone wiring in buildings that are called twisted-
pair wires. High-speed is defined as the video signal that is compressed using a
compression protocol.
In today’s current society we use medium speed the most due to the fact that it is
compressed over the internet. The speed of it is 128,000 to 256,000 bits per
second
8. CLASSROOM TECHNOLOGIES USED FOR ONLINE
INSTRUCTION
An important asset to having a successful online classroom is not technology but
how it is utilized.
When choosing appropriate technologies for online instruction students must
assess the available instructional technologies. Also they have to determine the
learning outcomes, identify learning experiences and match each to the most
appropriate and available technology
9. INTERNET-BASED TECHNOLOGY
There are several different versions of web-based technology. In the early 2000’s a new generation of web applications.
Web 2.0 technologies are:
Blogging
Wikis
Podcasting
Social bookmarking
Social networking
Virtual words
10. SUMMARY
Technologies used for distance education fall into two categories which are:
1. Telecommunications technologies that connect instructors to distance learners
2. Classroom technologies that record, present, and display instructional
information.
Effective utilization of distance education classrooms requires a new set of skills
for most educators and learners
