1. Internet congestion at peak times ==>
slow uploading and
|
|
downloading of PowerPoint, audio, video
files
|
|
2. Internet connections break down or service
is interrupted ==>
|
|
happens in Colombia ==> Colombia
ruled out as a site for
|
|
distance courses (for now)
|
|
3. Time zone differences make it difficult to
find an appropriate time
|
|
for the teacher and students to meet
in real time (synchronous),
|
|
e.g. in the GSL520 Chatroom
|
|
4. For the students it is necessary to have
some facility with
|
|
computers, a basic level of
competence, and a certain amount of
|
|
confidence so that they feel
comfortable following technical
|
|
instructions and doing some
troubleshooting themselves.
|
|
5. Putting the CALL course into an online
format has resulted in the
|
|
faculty member putting in approximately
double the preparation
|
|
time.
