Here is perhaps my final version of this module. The display now elegantly says "No attempts have been made on this quiz" once the final attempt has been deleted.
Re: Quiz Overview Module - delete attempts v. 1.3
I've checked this functionality into CVS. During my review I actually made a lot of changes to the code but it's a lot easier starting with a working product so thank you.
In line 101 of report.php it shows $clearalll instead of $clearall...
(Button label does not show)
Small suggestion for button names:
- delete selection
- clear selection
- delete all

Not for me, I will use the refresh button but I was wondering about our 700 normal schoolteachers starting using computers with Moodle on it for the first time in their life:
"Hey this machine goes black and I did not even touch it."

A little story:
In1982 there was one school in the Netherlands far ahead of the rest: Odulphus college in Tilburg. On personal computers (Commodore PET?) students did tests and at the end the results came out the printer on chainpaper. As a kind of service one page was filled with statistical items like average, standard deviation etc..
Asking teachers how they liked that they all said: GREAT!!
... until one teacher added: "Yes, we like it because that is the only place where we can tear off the paper without losing the answers of our students."
(citation: Jan Schoenmaker, a Dutch educational computer pioneer.)
Looking in this spirit to quiz-results I am a happy man:
- In a glance a teacher can see in simple statistics: are my questions (to) difficult?
- In detailted statistics I jump to the yellow pastille and see: are my questions good?
I only miss now the third one: multipercentages, where I can see in a glance:
are my m.c.-alternatives good?
In my Dutch translation I call the headers this way, so...
Please, can I have this yellow one back?
It would be a simple matter to modify (improve?) the script so that any M/C choice with fewer than 10% -15% selecting it would appear with a yellow background. Is this what you want?
Yes you are right it is there, I missed it, attracked as I was by that discrim.index.
(without reading it, I thought that it was some Japanese calculation explanation of the discrim. index )
I would prefer % in the M/C rows above the discrim. index, not the counting numbers
Also in the line just above discrim. index, the label says it gives percent correct, but it shows up as a fraction with a percent-sign. 0.4% instead of 40%
I have fixed the problem with the maths on the "Percent Correct" line but haven't committed it yet because I just got a new computer and CVS didn't come pre-installed. Hopefully, I can do this tomorrow.
The reason for the error was due to the changes made to the Excel output recently. They both draw on the same data, but Excel needs the numbers already pre-divided by 100.
I agree that percentages would be better, but to implement percentages in the M/C rows will not be so easy because the data is stored as a string with the response and the number together. Obviously this is/was poor programming style since I would now have to parse the string to get the number in order to calculate the percentage.
I think i'd better "go back to the drawing board" on this lest the code get too complex and difficult for future programmers to figure out or modify, so please be patient. I'll get to it eventually!
