Extension talk:Quiz

Suggestions de David Crochet sur le café de la wikiversité
L'évolution du système pourrait permettre de pouvoir donner une réponse chiffrée. Ce qui permettrait de répondre à des question de type : " quel est le nombre de planètre du système solaire ? " sans que l'on ai besoin d'indiquer tous les choix possible imposés de réponses.
 * Autre évolution possible : lorsque l'on demande les résultats, indiquer seulement si la réponse à la question est (vrai|fausse|non répondu) (avec le trait vertical à gauche de la question) ce qui permet de se corriger et premettre de re-répondre à la question ; puisqu'avec la méthode actuelle, on voit directement la bonne réponse en demandant la correction.

Different versions of documentation
I was looking at some earlier (?) versions of the extension-writing documentation on other wikis, and it seemed to be longer. Is this the authoritative version here? McCormack 05:15, 6 April 2007 (UTC)
 * This is all known "help on syntax" written so far :

Lrbabe 08:09, 7 April 2007 (UTC)
 * a bad one in french on my own wiki
 * a good one from Michael Frey on the wikiversity
 * an old one in french and english (you can change the language at the bottom of the page) with outdated syntax.


 * Thanks :) McCormack 08:53, 7 April 2007 (UTC)

Status of implementation
I see that the quiz extension is working well on DE.wikiversity.org, but it does not appear to work on www.mediawiki.org (which makes documentation difficult).

What is the status of implementation? How likely is it that the quiz extension will be accepted and implemented on EN.wikiversity.org? When will it be on www.mediawiki.org ?

McCormack 06:03, 6 April 2007 (UTC)


 * It already works on en.wikiversity.org, see v:Special:Version. But it will never be installed on mediawiki. We have to take screenshots of examples on the wikiversity and insert them in our help. Lrbabe 08:09, 7 April 2007 (UTC)


 * Ah. Is there any reason why it won't be installed on MediaWiki? McCormack 08:31, 7 April 2007 (UTC)


 * Because we don't need it? robchurch | talk 08:19, 11 April 2007 (UTC)

Wishlist

 * Possibility to exclude the options and colour key at the top - e.g. using &lt;quiz display=simple&gt;. This would enable people to insert miniature one-question quizzes into their articles without too much space being taken away by the options table.
 * Simple text Typed response (yes - I see you're already planning that one). Possible syntax:

What is the capital of France? {Paris}

(Answer marked by curly brackets and replaced with a textfield when first displayed to the learner.)
 * Cloze/gapfill, conceived as a multiplication of simple text typed responses within the same question. Possible syntax:

The capital of France is {Paris} and its people speak {French}. Its most famous emperor was {Napoleon}.


 * An important feature for simple typed response and gapfills is to support alternative answers. I suggest separating them with a pipe.

What language do people speak in Canada? {English|French}

McCormack 06:13, 6 April 2007 (UTC)


 * Similar to the simple Text input, i'd like to have a number input.
 * I mean with tolerance, min/max (all betwen is correct) or something like that.
 * A nice to have is then, support of different number systems like binary and hexadecimal.
 * -- MichaelFrey 13:47, 6 April 2007 (UTC)


 * Hi Michael. I'm curious about your numerical idea. I wonder whether this plays to the strengths of a wiki? Programmers love mathematical things, but wikis are very text-orientated things. On the other hand, why not? But if it makes things too complicated... McCormack 08:29, 7 April 2007 (UTC)


 * You both have very good ideas, I'll work on it as soon as possible. Lrbabe 08:09, 7 April 2007 (UTC)


 * I'm interested in the "display=simple" option for miniature questions. This would make a huge difference for new learners. I'm also interested in the "numeric" question type where a possible syntax could be:

Using the graph above, what is speed of the car at t=2.0 s? {Answer|Tol}


 * Kruhly 04:43, 11 April 2007 (UTC)


 * Hi, Kruhly :) Not quite sure I understand your answer syntax. What's "Tol"? And how does this differ from the "typed response" type suggested? For example, numerical responses could theoretically use formatted fields, spinners, sliders, comboboxes... Or do you want a text field with no preformatting? Are you thinking of something like Moodle? McCormack 04:59, 11 April 2007 (UTC)

I've changed "simple text response" to "typed response" in my previous posts, as I think this is a better name for the thing. "Text" suggested the answer could not be numerical. "Typed response" would, to my mind, be both numerical and text. Or do we need something more for numerical responses? McCormack 05:20, 11 April 2007 (UTC)

Suggested revised syntax:

 {How many spheres in the pyramid?} + There are {32|thirty-two} spheres in the pyramid. || The answer is 32.

 {Name ONE official language of Canada.} + {English|French} || English and French are the two official languages of Canada.

Comments: in the answer section, text outside the curly brackets is displayed first time round, but the {...} section is replaced with a textfield.

Modified for gapfill/cloze (here showing two text fields):

 {Complete the following sentence.} + The most widely spoken language in Canada is {English}, but in the province of Quebec the majority speak {French}. || Feedback: French is also an official language of the whole of Canada.

McCormack 05:32, 11 April 2007 (UTC)

Tol is short for Tolerance -- sorry old habits die hard. I have not looked at the javascript or PHP so I may be off track here... my thoughts are that a numeric question type would be slightly different than a typed question type. I'm thinking that there would initially be a blank text field ( no correct answers or distractors) I'm assuming a unformatted text field returns a string and that  {Answer|Tolerance} are both strings when processed. Therefore, there would need to be a function like compareWithInTolerance(Guess,Answer,Tolerance) where Guess is the value returned via the text field. All the strings would need to be converted to floating points and my guess is that it would be done inside the aforementioned function. So if an "N" question type does not already exist, a syntax could look like:

 {Using the graph above, what is speed of the car at t=2.0 s?} + {4|2} m/s || {Correct, the answer is 4.|Incorrect, hint given here... and try again}

where Tolerance=2 would be a percent value not an absolute value, and implementing the hint would involve some more coding. The aforementioned syntax assumes that the units are provided by the educator. Another question type would be with a numeric answer and a drop down menu for unit choices. I would have to think about a clear syntax though -- this is a wish list right ;-)

Kruhly 06:47, 11 April 2007 (UTC)


 * Ah! I understand now. What do you think, Lrbabe? (Lrbabe is programming it). Tolerance is what Moodle has in its numerical responses as well. McCormack 07:24, 11 April 2007 (UTC)
 * A different point: just picking over the telegraphic brilliance of Kruhly's post. He inserted an idea for a syntax which copes with the need of typed & numerical responses for correctness-conditional feedback. In the feedback section, he put the whole feedback inside {...} and used a pipe to separate the two types of feedback. I was thinking about this before, but I didn't come up with such a neat way of doing it. McCormack 07:24, 11 April 2007 (UTC)

Ok, after having read each advises, my ideas are as follows: { A text field question Some text parsed as wikitext where you could even insert links. Then we have a { text field }. And another line of { text } with { two } text fields. You can specify the width (in numbe of characters) of the text field like thi{ s _1 }. You can allow more than { one|two|three } good answer. Lrbabe 10:42, 12 April 2007 (UTC)
 * The object type could be name "Text field" (or Textfield ?).
 * The symbol could be "{}" : type="{}".
 * the syntax could be :
 * type="{}" }
 * Here wa can add some feedback.
 * The whole object is parsed line by line, as if it was in a tag.
 * The text field syntax require to put the text between two spaces : { this will be parsed as a text field } {this will not be parsed as a text field }.
 * For numerical answers :
 * I prefer allowing tolerance with a min-max syntax, example : The human DNA has { 20000-100000 } genes.
 * With ECMAscript we could allow only numerical input in such text fields : try this "exemple"

Here is a preview of textfield : on my own wiki. Correction doesn't work today, maybe tomorrow ; ) Lrbabe 16:30, 12 April 2007 (UTC)

The new version is exciting. Some comments.... McCormack 18:58, 12 April 2007 (UTC)
 * You've condensed the three types we discussed into one (typed response, gapfill, numerical). Very efficient. Neat solution.
 * I like your max-min solution for numerical responses. Easier for non-mathematical people.
 * Why are you using spaces as well as curly brackets to mark textfields? I assume there's a good reason, but you didn't say.
 * Why are you using underscore as the divider for textfield width? Perhaps one should not introduce too many reserved characters - ? How about { answer1|answer2||width } (i.e. use a double-pipe).
 * Looked at your site and saw the display="simple" in there! Good stuff.
 * So how soon can we see the new version on Wikiversity ? :))

Terminology
I created a page on terminology for making quizzes, as I noticed that we are using critical words differently! Comment requested. McCormack 08:47, 7 April 2007 (UTC)

Didactic considerations
I've added a section at the top of http://en.wikiversity.org/wiki/Help:Quiz on didactic considerations for the use of the quiz extension. Comment is invited. One of the things which emerges from my analysis is that development of the quiz extension should pay less attention to points systems (marking, assessment) and more attention to layout and feedback (visuals, information flow). Any thoughts, anyone? McCormack 06:36, 8 April 2007 (UTC)


 * I agree that more attention to layout and feedback is appropriate. Kruhly 04:24, 11 April 2007 (UTC)
