Hi,
We are planning to add clues to each question in the quiz and deduct some % of marks for taking clues. could some one help me like where i have to modify for setting the provision for adding clues to the question?
There are two parts to this.
1. You need to add extra fields to the editing form for questions, so teachers can enter the hints - and arrange for those to be saved somewhere suitable in the database, and loaded again.
2. You have to change what happens when questions are displayed and processed, to add a 'show hint' button and then record when the student asks to see a hint so you can display the hint in that siuation, and then adjust the score.
That would be really quite hard to do at the moment, because the question processing code if fairly messy and fragile. You would mostly need to change lib/questionlib.php and question/type/questiontype.php.
Once Development:Question_Engine_2 is finished and included in Moodel 2.1, then this should be much easier. 1. is already done there, and 2. would be a matter of creating a new 'question behaviour'.
Thanks for your quick reply Tim, It will be usefull to us in adding clues to our moodle quiz
I have came across in moodle forum (http://docs.moodle.org /en/Development_talk:Question_Engine_2:Overview)that there was discussion going on long back regaring adding of textual hints with associated penaly to moodle quiz. Does this feature is available in moodle 2.0 now ? or can i get the patch from some where else to implement the hints functionality to moodle quiz .
The work described on that page will be part of Moodle 2.1. I am working on it now, and making good progress, but the code is not in a state where you could use it for real at the moment.
Okay tim, Mean while we will work on the files you specified for activating the clue feature for quiz questions.
Tim,
I have tried installing the new question available under the below url :
http://timhunt.github.com/Moodle-Question-Engine-2/
But the installation process is showing bugs on installing the question/type/opaque tables. could you help me in this?
I could possibly help, but you will need to at least copy-and-paste the error message here. I am not a mind-reader
Tim,
This is the error message am getting during installing the Question engine.

Oh, drat! That one. Sorry, that does not happen on Postgres, so I never bothered to fix it, although someone did report it before.
You almost certainly don't need to opaque question type, so you could just go and delete the question/type/opaque folder. However, I will try to commit a fix.
Thanks tim, It has installed sucessfullly after taking away the opaque question type.
Hi bala,
How it is possible to install 'Opaque' successfully by taking away.
Pl. clarify.
Warm Regards,
Ravi

I am saying that you almost certainly don't need the Opaque question type, so you should just delete the code before trying to install the system.
Hi Tim,
I am facing same problem in installing opaque question type.
Pl.assist.

Tim, We have sucessfully installed the question engine 2, also have created a quiz and addedd questions with hints. but hints are not showing up. Any other work around to be made for displaying the question hints.
At the moment, hints are only used if you switch to 'Interactive with multiple tries' behaviour.
Please think very carefully before you use Question engine 2 for anything other that evaluating the software and giving me feedback. While it is nearly finished, it is still software in development and I cannot promise any support. Also, if you install it today, there will probably not be an upgrade path to Moodle 2.1 with the new question engine.
Just for the record here is a patch that fixes the database creation issues
in old qtype_opaque code that is still available at http://download.moodle.org/plugins/question/type/opaque.zip
It would be great if someone could apply the patch and create a new zip until
engine 2.1 becomes generally available.
hi.how can i apply this patch on moddle 2.0. please help me?
