[Building Sakai] NeoChat for production use?

Thu Feb 21 02:12:09 PST 2013

Hi Keli
I guess you're assuming that you are using a browser crash program to 
complete the exam, like Respondus Lockdown Browser?  If not, any student 
can communicate with his Connections in PortalChat from anywhere, 
including MyWorkspace (although the PortalChat of the site of the 
examination is locked). Am I right?

Thanks
Regards!

However, I seem to recall some thread a few months back citing concern about students over-collaborating (aka cheating) during timed online tests. Unlike a chat room, the instructor has no visibility into what's being said and can't remove the ability of students to talk to others in their class. Also, we are are in the process of disabling the ability of those with a guest role to see tools that show who is in the class because we are concerned about FERPA (Forums and Wiki for now, and if we start using them more, Messages, Chat Room, and Roster).

And possibly, to prevent chatting with My connections and/or develop a tool to show whether two people are chatting (don't think we need to see the content of the chat) in case there is some sort of investigation.

And does "everyone" for online status really mean everyone or just those who are in my classes and clubs? Might rename that option to "members of my sites" just for "who can see my online status"

> Barring that, the two scenarios I described above could also be met by the Chat Room alone. Neochat would allow students to ask questions directly to the instructor without letting other students see the question and neochat makes it easier to stumble upon other people who are online, because you could be in another part of the site. However, it would start getting harder to manage if more than 4 students ask a question, since new names pop up along the bottom, so maybe chat room is better.

> So, I wonder if anyone has any *other* use cases for neochat? I could see this being used more socially than anything else, so it might change the nature of Sakai use on your campus, causing people to stay logged in longer. I imagine that if schools wanted to experiment, they might create a skin that hid the chat in all but a few pilot courses, assuming that was possible. I don't think that would solve potential performance issues, because that is still in the background, but it would allow them to run usability tests without exposing chat to the whole class.
