On-line Office Hours
(answer individual questions)
Listserv/E-mail
Strengths
- E-mail nearly ubiquitous
- Can be restricted to list members only, or be private between a faculty member and student
- Very interactive; communications can feel more personal
Weaknesses
- Attachments may be difficult to impossible to send
- Responsibilities of list owner can be time-consuming
- Some students may not want discussion to be publicly accessible to rest of the class
- Server load can be severe
MOO
Strengths
- Allows for near real-time interaction
- Material can be made into objects accessible only by certain permitted participants
- May appear as a more natural way to have open discussion
Weaknesses
- Can be difficult to access given crude client and style of the environment
Netnews
Strengths
- Easy to post
- Easy to view: newsreaders widely available and widely used
- Ability for followup discussion and clarification
- No recognized resource load on servers
Weaknesses
- Postings inherently public, at least to the campus community
- Poster's identity can be forged with relative ease
WWW
Strengths
- Faculty member retains the most control over material
- Widespread use of WWW browsers, even moreso than netnews
- Little to no marginal server resource impact
Weaknesses
- Students must actively search out material
- Difficult to support followup and discussion without additional design and coding
