The skills booklet allows to synthetically read the whole scored work of the participants of the class.

It consists of skills (at most $maxcomp), each one can possess several stages (up to $maxpalier).

</p><p>

For each stage, the teacher can define the list of series of exercises in the class for which the

score is used for computing the level of acquisition of the stage.

</p><p>

The teacher of the class can decide that some virtual worksheets are neutralized when computing the 

degree of acquisition of the stages in the notebook of skills (it allows to keep the educational 

data from one year to the next while allowing to begin validating some skills).

</p><p>

The computation of the level of acquisition is done as follows :

</p><p class="wimscenter">

!insmath 10 \times \frac{\sum_{i=1}^{N} NM(x_{L[i;1],L[i;2]})}{\sum_{i=1}^{N} \delta_{L[i;1]}}

</p>

where

<ul>

 <li> <i>N</i> is the number of exercise series occuring in the stage.</li>

 <li> <i>L</i> is the list of exercise series occuring in the stage. Each element of this list contains 

 the number of the worksheet (denoted by  L[i;1]) and the number of the exercise series 

 in the worksheet (denoted by L[i;2]).</li>

 <li> 

  !insmath X_{i,j}

  is the quality score for the exercise series <i>j</i> of the worksheet <i>i</i>.</li>

 <li> 

  !insmath \delta_i

  is 1 if the worksheet <i>i</i> is not in the list of worksheets desactivated for the calculation of 

  the acquisition level of the stages and <i>0</i> else.</li>

 <li> NM(a) is <i>1</i> if  and <i>a</i> is more than the minimal score needed 

 to consider that a series is correctly done and <i>0</i> else 

 (choosing this minimal score to <i>0</i> neutralizes this option).

 </li>

</ul>

<p></p>

<b><u>Remark</u></b>: if you change the status of a virtual worksheet, class participants have to exit

the skill booklet to view change

if they are looking at the skill booklet. If not, acquisition level will be totally wrong !!!
