1: ILS Package for .LRN
Posted by Rafael Chacon on 03/05/10 04:12 PM
I'm looking for a package to apply ILS (index for learning styles) questionnaire in .LRN. I have been looking for it, but I'm unable to find it. Could you tell me where I can find it?

Thanks

Hi Rafael,

At aDeNu (UNED) we implemented ILS for .LRN. It's a simple application (+ portlet + applet) to implement the questionnaire and compute the result to give feedback to the user. There's a callback on questionnaire completion so the results can be used by any application/service that implements the callback.

You can get the code from our CVS (:pserver:mailto:anonymous@cvs.adenu.ia.uned.es:/cvsroot), packages are: ils, ils-portlet and dotlrn-ils.

Hi, thanks. I download and installed the packages properly. But when I try to take the quiz to test it... it arises an error:

Do you know why is this happening?

thanks!

Oh ok. I found what it was. template:form:get_properties is no longer a function in template. I changed it to template::form:get_values and it worked fine.

Maybe is a good idea to made this changes in the mainstream of ILS :)

Greetings

Hi Rafael,

template::form::get_values and template::form::get_properties are not equivalent and do not return the same result. Although changing the call to get_values avoids getting the "missing proc" error, it won't get the data needed by the script.

We (UNED) added the get_properties proc in version 2.5 but we did it locally and forgot to contribute it back to the openacs.org repository, our bad. I've fixed that and the proc is now available at oacs-5-5 branch and on HEAD.

If you are using the last stable version, update your acs-templating/tcl/form-procs.tcl file from openacs.org repository, branch oacs-5-5.
