1.
Internet congestion at peak times ==> slow uploading and
downloading of PowerPoint, audio, video files
2.
Internet connections break down or service is interrupted ==>

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.
