I've installed the Tutor (teacher) version of the Sanako Study 1200, a VOIP language lab package on the Mac mini and the Student version on the iMacs. Martin and I took it for a bit of a test drive and it appears at least generally useful. We had some trouble figuring out how to get files to students, though. What it needs is a shared directory where it can find files. It creates a folder structure which duplicates the "sessions" available (A-F) and requires files to be shared to be stored in the appropriate directory. I'm sure there's a method of automating it, but haven't found it in the provided docs yet. Anyway, I got that working. Network speed is, of course, no issue. Also, shared drives (like squash) need to be pre-mounted on student stations before playback can occur. This makes me wonder if we'll need a server OS on teacher stations if ALL materials are on the server. If so, I can fiddle something on the server to accommodate the XP connection restriction AND the teacher desire to bring in materials as they see fit.
I also sent some of Dr. Niang's video files (40-sh to 60-ish MB each) and they just worked. Bang!, they were up and running without having to download the whole thing first. That is fabulous.
The one thing I have not found is a method of doing the telephone conversations that Lab 300 supports. Frankly, I suspect they've dropped that as the network overhead would be crippling.
The system appears to be based around an initial feature set that can be augmented by purchasing modules and incorporating them. The interface apparently remains the same, merely adding buttons and so forth to the existing GUI. Modules to add include Blackboard support (ugh), and a content creation module (audio, video and the like). There are others, but I can't download any to assess their value.
Conclusion for today: I think we should talk to U of A about their experience with it, and get a ballpark quote for the record.
