How does a “good” poster look?
More active posters are more interactive
Regular, active (but not overactive) participation: good
Posting in too many groups or dominating threads: bad

Experiments and CMC

Experimentation vs. Observation
What’s the key difference? Assignment of treatment (or condition)

Putting Experimental Work in Context
Selection of subjects (i.e., what do they value?)
Task length and learning
Accounting for time in statistical analyses
Do not assume that an experiment is even trying to ‘recreate’ a specific real-life situation unless they explicitly say so.
