DISADVANTAGES (cont’d)
4Possible equipment incompatibility
4Internet congestion at peak times
4Unreliable Internet connections/ intermittent service overseas (Colombia)
4Time zone differences
4Students must have basic computer competence, facility with basic troubleshooting, and certain confidence level
4approximately double the preparation time for faculty member
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.
