Activities: Question Practice

Maintained by Picture of Marcus Green Marcus Green
A teacher sets up a bank of questions organised into categories. Then the student can then choose what categories they want to practice when.

This activity uses the standard Moodle question types (plus several third party question types). A teacher can set up categories for students to select from and they can practice on their own. It works best with a fairly large bank of questions.

It is possible to experience it from a student point of view at this site

    Hi Anthony,

    First of all thanks for including this as a part of Moodle plugins. I am glad that this module will help lot of people to practice and analyze themselves.

    Coming back to the queries you reported, I will like to answer them in point by point.

    1.) Yes the 2 small fix you talk about are missing namely :
    Maturity information ($module->maturity) not found in version.php
    Release name ($module->release) not found in version.php

    2.) The code I uploaded while creating the request is old one. I have an updated codea at my github link, it will be kind of you if you can download code from their and test that. That code is kind of perfect code with no errors or so. You will need to uninstall the module and add module again and all the errors you reported will be solved. I have tested same with community and there was good response.

    3) Yes documentation about the same is in progress, I will update it as soon as possible. Link to documentation is :

    Please let me know if I missed something while answering to your response. Do I need to an attachement and update version here?
    Thanks for reviewing the code.

    I uninstalled and used the code from Github and am still seeing the database write error. I'll let you upload a new version. I am still not seeing the question categories in a course so I suspect that the error may be related to that. I'm going to go ahead and edit the entry to provide the URLs. I'll leave this marked as needing some work until we can get past the database write error. Peace - Anthony

    Anthony, I think the problem may be that during development, we have not correctly used upgrade.php. Can you try completely uninstalling the plugin (from admin/modules.php) then letting it re-install. That shoudl fix the DB error.

    Tim - I am still getting an error:

    [Wed Sep 11 09:13:10 2013] [error] [client] PHP Notice: Undefined property: stdClass::$categories in /var/www/m25/mod/qpractice/locallib.php on line 71, referer: http://localhost/m25/mod/qpractice/startattempt.php?id=594
    [Wed Sep 11 09:13:10 2013] [error] [client] Default exception handler: Error writing to database Debug: Column 'categoryid' cannot be null\nINSERT INTO mdl_qpractice_session (time,goalpercentage,noofquestions,practicedate,typeofpractice,categoryid,userid,qpracticeid,questionusageid) VALUES(?,?,?,?,?,?,?,?,?)\n[array (\n 0 => NULL,\n 1 => NULL,\n 2 => NULL,\n 3 => 1378908790,\n 4 => '1',\n 5 => NULL,\n 6 => '2',\n 7 => 1,\n 8 => 12,\n)]\nError code: dmlwriteexception\n* line 426 of /lib/dml/moodle_database.php: dml_write_exception thrown\n* line 1089 of /lib/dml/mysqli_native_moodle_database.php: call to moodle_database->query_end()\n* line 1131 of /lib/dml/mysqli_native_moodle_database.php: call to mysqli_native_moodle_database->insert_record_raw()\n* line 78 of /mod/qpractice/locallib.php: call to mysqli_native_moodle_database->insert_record()\n* line 71 of /mod/qpractice/startattempt.php: call to qpractice_session_create()\n, referer: http://localhost/m25/mod/qpractice/startattempt.php?id=594

    I took a quick look and am wondering if we aren't sending the wrong context to populate categories:

    $context = context_module::instance($cm->id);
    $categories = $DB->get_records_menu('question_categories', array('contextid'=>$context->id, 'parent'=>0), 'name', 'id, name');

    It looks like we are sending the course module context id and I thought that the question_categories table stored the course context id. As a result I am getting an empty array of question categories. I also found myself wondering about the need for the parent=0 condition. Is the intention here to generate a list of all the question categories for the course?

    Peace - Anthony

    p.s. - I added/modified the following lines and it seemed to work the way that I would expect:

    $coursecontext = context_course::instance($course->id);
    $categories = $DB->get_records_menu('question_categories', array('contextid'=>$coursecontext->id), 'name', 'id, name');

    No. It is module context by design. That is how the teacher controls which questions are available for practice. They move or copy them into that context.

    It is also intentional that we only offer a choice of top-level categories in the UI (though that decision might get reviewed.)

    Ah, I see the problem:

    1. Create a new practice.
    2. Don't add any questions to the question bank.
    3. Click the Create a new session link.

    Actual result: You get the start session form with an empty Categories drop-down.

    Expected result: The Create a new session link should now appear if there are no questions in the question bank yet. Instead we should display a message something like "No questions have been added to the question bank yet."

    Tim - OK, now I understand how it is designed to work. I had not noticed the additional default question category for the qpractice activity. I think what is unclear is when or where to add questions or select the category. There is not a place on the initial creation of the qpractice to do so, perhaps that might be added or perhaps the next step would be to take the user to the question bank page for the activity (for example, http://localhost/m25/question/edit.php?cmid=596). The current flow seems to allow you to create a qpractice and then the only options are to start a session or review. Perhaps if the user has the capability to add questions we might add a link to the question bank to the question bank edit page. At some point, I suspect teachers will want to be able to review the sessions of the students too. In any case, I understand what was causing the error and I think it can be improved. Some confusion may arise from the distinction between the qpractice activity's question bank and the course's question bank. We may want to think about how to make that distinction apparent to the user. Peace - Anthony

    Thanks for helping me to understand how this works. I'm going to go ahead and approve this now that the URLs are available and it is generally working. It would be good if we could take care of adding release and maturity variables to version.php for the next version added to Moodle plugins. Peace - Anthony

    Nice contribution guys, I've been using it heavily. I thought it would be nice if we could control the order in which questions are shown to student so i made some mods to it. I also combined the create session and session history pages to simplify it a bit. I'd like to contribute to this project, so if you think any of this is of value let me know. I've fixed the upgrade.php install.xml etc so it does a clean install. Luck++

    Hello Carl LeBlond,
    First of all thank you for using Qpractice module.It was good to hear that the module was of great use to you.
    I am quite new to open source, so while it is great you want to contribute, i am not very experienced at recieving contributions, so please be patient.
    The whole idea of module is to ask random questions to students. If we were to control the questions being asked then it will be almost similar to Quiz module.We are working on algorithm that will ask questions randomly but in an efficient manner.

    please do you plan to adapt Qpractice module for Moodle 2.7/2.8 ?

    Best, Miro

    Hi Marcus. May I suggest to extend a bit the plugin description here and add more screenshots that would better illustrate the student's workflow.
