Evolution of ODL

The concept of ODL is intricately intertwined with technological development. Over the years, Communication between the education provider and the learner, and provision of learning resources has been mediated by technology, ranging from the correspondence model that used print-based technology to the present-day flexible learning model that uses computer-mediated communication, including the web base technologies.

Below is a summary of how open, distance and e-learning has evolved.

Generations

Features

1st Generation Correspondence Model

Based on print technology and are still the most widely used form of ODL in less developed country.

2nd Generation

Multimedia Model

  • Encompasses text, audio, video, and computer-based materials—face-to-face learner support.
  • Use of Educational television and radio systems to deliver live or recorded lectures 

3rd Generation

Telelearning Model

Based on applications of telecommunication technologies to provide opportunities for synchronous communication

4th Generation

Flexible Learning Model

Based on online delivery of multimedia (text, audio, video, and computer-based) materials in electronic format delivered via the Internet.

5th Generation

Intelligent Flexible Learning Model

Includes
  • Interactive Multi-Media (IMM),
  • Internet-based access to WWW resources, and
  • Computer-Mediated Communication (CMC).

Reflection:

At what stage is your institution in the evolution trajectory of ODL? What’s the level of efficiency and effectiveness in the delivery of instructional content?

Summary

In this lesson, we have learned that there are many approaches to defining the term Open and Distance Learning. However, there are characteristics common to most of these definitions that would help us understand this concept. We have also studied how ODL has evolved over the years based on technological growth. This introduction helps in laying the foundation in appreciating the ODL that our institutions practice today.
