Hi,
I want to get the number of questions attempted by a student in a moodle quiz. Lets assume that a quiz contains 20 questions and the student answers only 10 questions, I need to get the count as 10 since the number of questions for which the student has answered is 10.
Thanks,
Dharani Kumar
Are you trying to do this using the Moodle interface, or by writing PHP code?
Hi Tim,
I am trying to do this by writing PHP code. My intention is to calculate the accuracy of the quiz where the accuracy is nothing but no.of correct answers given by the student divided by the number of questions attempted by the student.
Is there any way to get this result directly by moodle interface?
Thanks,
Dharani Kumar
Well, you can see which questions have been answered in the quiz reports, but you cannot easily get the number through the UI.
You can get this in PHP or SQL code. It is easier for me to explain in terms of SQL code. Start from this query: http://docs.moodle.org/dev/Overview_of_the_Moodle_question_engine#Detailed_data_about_an_attempt. You don't need it all, so you will be able to simplify once everything is working. You need to look at qas.state, and count the number of questions in each state.
In PHP code, it looks roughly like this. Assuming you have a $quba object: (See http://docs.moodle.org/dev/Using_the_question_engine_from_module if you need help with what that means)
$answered = 0;
foreach ($quba->get_attempt_iterator() as $qa) {
if ($qa->get_state()->is_graded()) {
$answered += 1;
}
}
Thanks for the help Tim. Intially I got the quba object by using question_engine::load_questions_usage_by_activity($qa->uniqueid) and used your code . I could see the number of questions attempted by the user now.
Hi,
I'm also having same issue.
i'm bit confusion on this. Please explain me how to do and in which file we have to write the PHP code for this.?
Thanks in Advance.
