Technology tools have merits and limitations. Many tools are designed for specific uses while others have broader application. It is important for developers to understand what is in their toolboxes. A carpenter uses different tools to complete finish carpentry work than he does to frame a structure. Likewise, distance education developers need to select different tools for enabling interaction than they would in presenting content.

Instruction, regardless of delivery format or subject matter, can be divided into four basic components:

Content – Present information, concepts, principles, and theories.
Meaning – Enhance understanding of information, creating knowledge.
Application – Use information and knowledge acquired.
Interaction – Discuss and test information and knowledge acquired.

As shown in the course development model below, developed by Iowa State University's Richard Carter (Brenton Center), where content, meaning, application, and interaction overlap, true learning takes place.

The tables on the following pages compare five delivery modes in presenting content, providing meaning, applying concepts, and interacting with and among students. Selection of the delivery mode impacts the technological available and the ‘tools’ an instructor can employ. Evaluation of these factors was made subjectively, based on experiences in dealing with specific infrastructure, support, and content. The tables are to help you compare tools for your specific situation.

Delivery Modes for Presenting Content
Delivery Modes for Enhancing Understanding (meaning)
Delivery Modes for Using Information and Knowledge (application)
Delivery modes for Discussing and Testing for Knowledge Acquired (interaction)

Now let's review what we've learned.
