[LON-CAPA-users] Support research and win an iPod Shuffle
Thu, 21 Aug 2008 13:55:22 -0400
Lars Hoeppner, whom some of you met at the LON-CAPA Conference this
year, is working on his master's degree with the Fern-Universitaet
Hagen in Germany. His topic is community-supported search in an
educational content pool with sparse metadata, aka LON-CAPA.
There are a number of possible algorithms for community-supported
search, and the last phase of his project is evaluation by users.
As you are likely setting up your courses this week, please give it a
using your normal usernames and password, and by hand changing the
"Domain" field to your domain. Then go to the course you want to be
working on and use Search like you normally would.
You get a choice of mechanisms and parameters. Try out a few and
please evaluate the search results using the
How well do the results meet your expectations?
(bad) 1 2 3 4 5 (good)
field at the top. Please don't forget to "Send".
Note that the time it takes for these searches is not a valid
reflection of the search time in an actual implementation. Also note
that the cataloging data is from earlier this summer and may not
reflect most recent changes. The actual implementation is not going
to have all the currently available options; the purpose of this
evaluation is to find the best algorithm. The "start user" needed for
some search algorithms will eventually be determined automatically
from your preferences and profile information. Please, for now, just
use colleagues teaching the same kind of course.
Everyone who submits more than 10 evaluations before the end of
August automatically enters into a raffle for an iPod Shuffle.
Thanks for your help,
