From the list below:

a learning management system
a blog
online collaborative learning
Twitter
virtual worlds (e.g. Second Life)
a podcast
an open textbook

1. Determine which is a medium and which a technology, or which could be both, and under what conditions.

learning management system	either: technology as software, medium when used for course delivery
blog	medium (WordPress or other blog software is the technology)
online collaborative learning	medium
Twitter	either, but mainly a medium
Virtual worlds	medium
podcast	medium
open textbook	medium

2. Decide where, from your experience, each medium or technology should be placed on Figure 6.4.3. Write down why.

Activity broadcast 2 3. Which were easy to categorize and which difficult?

Difficult:

online collaborative learning, because it is highly communicative but the teacher has a good deal of control over the medium
Twitter, because it is definitely under the control of the learner, but it is also as much a broadcast as a communicative medium.

With both these, I gave more importance to the broadcast/communicative dimension compared with the control dimension.

4. How useful?

Understanding where different media are likely to fit on the broadcast/communicative dimension will help in choosing media, depending on my epistemological position. If I want a high level of student activity and interaction I would tend toward more communicative media. If I am more concerned with information transmission and comprehension, I would tend to use more broadcast media. However, in most cases I would want a mix of both. Knowing where each medium ‘fits’ on this dimension is one component I could use in my decision-making.
