TECHNOLOGIES
FOR DISTANCE EDUCATION

2. • Chapter Goal
The purpose of this chapter is to discuss the technologies used
for distance education systems and distance education classroom
Chapter Objectives
1. Describe systems for categorizing media used for distance education
2. Explain the technologies used to connect teachers and learners for
distance education including correspondence and desktop systems
and audio and video
3. Explain the configuration of a modern distance education classroom
Goal and Objectives

3. • The southeast African nation of Zimbabwe was founded from the British
Commonwealth country of Rhodesia
• The educational system controlled less than 500,000 learners and most of
them were in major cities
• Teachers in training were said to have attended one of the institutions of
higher learning
• College students functioned as regular educators with two exceptions
• They were under the guidance of a more experienced colleague
• They continued their teacher education and higher education coursework at a
distance

Field of
experience

5. • Children respond to direct, purposeful experiences, not only because
they are young, but also because they are learning many new things
for the first time
• As learners grow older and have more experiences, it is possible for
them to understand events that are realistic and more abstract
• Learners need to have direct, purposeful experiences to draw upon in
order to successfully learn from more abstract events
• Media permit the educator to bring sights and sounds of the real world
into the learning environment
Cone of Experience

6. • Variety of techniques will be needed to provide equivalent learning
experiences for all students
– Correspondence study
– Prerecorded media
– Two-way audio
– Two-way audio with graphics
– One-way live video
– Two-way audio, one way video
– Two-way audio/video
– Desktop two-way audio/video
A Taxonomy of distance
education technologies

7. Prerecorded Media

8. • Step # 1: Assess available instructional technologies
• Step # 2: Determine the learning outcomes
• Step # 3: Identify learning experiences and match each to the most
appropriate available technology
• Step # 4: Preparing the learning experiences for online delivery
Classroom technologies for
online instruction

9. 1. Linear programmed instruction
2. Branched programmed instruction
3. Hyper-programmed instruction
4. Student-programmed instruction
These models consist of topics that relate to one another or have some
sense of unity or consistency such as economic condition of the South
after the Civil War
Four strategies for online delivery

10. Technologies used for distance education fall into two categories:
telecommunications technologies that connect instructors to distant
learners and classroom technologies that record, present and display
instructional information.
