<li>Author-controlable multiple choices: checkbox,
click, menu,
radio, mark, flashcard
These can be used to replace the standard multiple choice input, giving
you more control on its appearance. The correct answer should contain two
fields, separated by a semi-colon ;. The second field (after
the semi-colon) is the list of choice texts, and the first field is a list
of numbers of the correct choices. In the case of checkbox
and of flashcard, the user
must check exactly all the correct choices. For all the
other cases, any correct choice will be enough.
In case of flashcard, the third line is showed on the hident face of the
cards (default: interogation points).
For types checkbox, menu, click,
radio and flashcard, an option
called shuffle can be specified, that has the
effect of randomly shuffling the order of items in the multiple choice
presented to students.
Automatic shuffle is not applied without the option shuffle,
and the number of choice items is not automatically cut.
And for an opposite effect, the option word sort makes the items
always presented in alphabetic order.
click should be used only in the case where there is no other
replies or choices.
The type menu accepts an option multiple with value. The
value of this option gives the maximal size (by default 8) of the choice
window. For example, multiple=5 gives a multiple menu window up
to 5 lines.
mark works similarly as checkbox, with the difference
that instead of a button, the chosen item itself will change color. It is
therefore principally for inline use.
In case of flashcard, the choices (cards) are hident and the correct choices
must be returned. With the option show, the cards are seen and the correct choices
must be hiden. The number of clicks on each cards are send in the second line of
the variable \replyn.
For types where several choices can be entered (checkbox,
mark, as well as menu with option multiple),
by default the student will be zero score whenever the answer is different
from the given correct answer. If you want to give partial score for partially
correct answers, you can add the option word split (synonym:
partialscore. In this case, the partial score will be computed
according to the proportion of correct answers picked by the student. On the
other hand, if wrong answers are picked, every wrong answer will compensate
two correct answers until the score reaches 0. Such a policy is necessary,
among others, for dissuading people from taking all the available choices
in case there are many correct ones.
While such a formula should fit most of the situations, you can add an
option word eqweight if this is not your case. This word forces
the computation to be of equal weight both positively and negatively,
that is, every wrong answer compensates only one correct answer. But you are
warned that this seemingly just policy may lead to weird effects!
Dans le cas d'utilisation de la commande \embed, il est possible de placer
précisément le k-ème item en écrivant \embed{rn,k}
avec n le numéro de la question. Dans le cas de flashcard, on peut de plus
préciser sur les deux lignes suivantes le style css des cartes (style associé à la balise div).
(il doit être le même pour chaque carte, dans le cas de style différent, c'est le dernier placé
qui est utilisé dans la réponse).
Par exemple,
<pre>
\embed{r1,4
style="display:inline-block;min-width:30px;min-height:30px;padding-top:10px;padding-bottom:5px;background-color:red;"
style="display:inline-block;min-width:30px;min-height:30px;padding-top:10px;padding-bottom:5px;background-color:blue;"
}
</pre>
