| Streaming
media |
Requires student to have
networked computer to listen and view. |
Each presentation can
be completed just prior to release. |
Referenced material can
be incorporated in presentation by the simple use of a hypertext
link. |
Requires a media-server
for optimal delivery although a basic Web-server (http) will suffice. |
| CD-ROM
or DVD |
Can be run on an off-network
computer and, in the case of DVD, a TV with DVD-player. |
Presentations need to
be completed far enough in advance to allow for compilation of reasonable
amounts of material and physical distribution of disks. |
If the referenced material
is to be viewed off-network, it must be harvested, formated and
integrated on the disk alongside the audio material. Permissions
may also be an issue. |
Disk-production has moved
to the desk-top and is, taking account of the distribution costs
alone, remarkably inexpensive. |
| MP3 or
equivalent |
Once downloaded, can
be run on a portable music player or PDA as well as a computer. |
If distributed via download
can be completed just prior to release. |
No tight connection to
referenced material although the audio can provide instructions
to view particular text or a chart, separately distributed. |
Requires only a Web-server
to hold the files for student download. |
