[LON-CAPA-users] Open date versus Contentopen?
Mon, 02 Jun 2008 21:24:48 -0600
Using pages does have some interesting effects. I think they're
starting to get used more often now, but for a while it seemed many
things were not well optimized for pages, but I believe many of them
have gotten ironed out.
But directly to your issue: I ran into this a lot last summer when
trying to work with "Pages". I think everything below is still the
case, but I'm sure someone like Gerd or Stuart will correct me if I'm
wrong. From a LON-CAPA system standpoint, a "Page" is not any different
than a "folder" or a "sequence" except that everything appears on one
concatenated html page. Also, for better or for worse, LON-CAPA has
very limited cascading of parameters down through sub-folders. What
does this mean? Assume the following course structure:
If you set parameters like open/close/due dates on the enclosing folder
of "Folder 1", say by viewing the parameters of "Problem 1.1" or with
the "Overview" mode, the only resources affected will be "Problem 1.1"
and "Problem 1.2". The parameters will *not* cascade further down the tree.
If you view, for example "Problem 1.1.1", and use PPRM to set
open/close/due dates for the enclosing folder, the enclosing folder is
actually "Page 1.1", *not* "Folder 1". I for one would very much like
to see the automatic cascading of parameters down through all
sub-folders/pages, but this is apparently a bit challenging. First, it
could make for an even uglier PPRM page, but I suspect it has something
to do with not knowing for sure just how many levels may be present in
any part of the tree. At any rate, it just doesn't happen. You should,
however, be able to use the overview mode to set the parameters for each
"Page" in a slightly more efficient manner.
The current behavior of parameter cascading has the undesired side
effect of making Pages a much less useful tool. Although arguably quite
nice from a presentation standpoint, the management standpoint leaves a
lot to be desired. As a result, we ended up not using pages nearly as
much as I'd like, but instead resorted to multi-part problems.
One last item. When looking at a "Page" you've got to be very careful
which resource you are setting the parameters of. It sounds like you're
using the remote control. In this case, when you view a "Page", the
PPRM button brings up the parameters for the "Page" as a whole, not a
particular resource within the "Page". That is why you get "Content
Opening Date" rather than "Problem Opening Date". If you do not use the
Remote Control, you get the same effect by clicking on the "Set
Parameters" icon at the very top of the page. If you want to look at
the parameters for a particular resource within the page, you need to
use the "Set Parameter" links that appear scattered throughout the
"Page". They're actually not scattered, but appear at the top of each
resource. If you use the embedded link, you can get the parameters for
one of your embedded problems, including Open/Due Dates.
Hope that helps,
