12 | The server computes two averages for the work of each participant on each |

13 | sheet: a percentage of points obtained with respect to the number of points |
||
3929 | bpr | 14 | required, and the quality of points obtained on the exercises of the worksheet. |
23 | reyssat | 15 | Let x be the percentage and y the quality, both scaled proportionally |
16 | to values between 0 and 1. Here are the formulas for the computation of the |

7901 | bpr | 41 | Remark : For level 0 and 1, if the quality of points is less than 1 for an |
3571 | bpr | 42 | exercise, the percentage of points obtained |
7901 | bpr | 43 | become 0% for this exercise when x is computed ; if the quality of points is betwwen 1 and 2, |
3571 | bpr | 44 | the percentage of points obtained for this exercise is divided by 2 |
45 | when x is computed. |

48 | Pour cette feuille, votre enseignant a choisi le mode de calcul suivant |
||
49 | de la note. |
||
50 | Pour chacun des indicateurs suivants, on calcule la moyenne pour votre travail pour : |
||
51 | <ul> |
||
52 | <li> |
||
53 | !if $help_sw=0 |
||
54 | le quotient I des points cumulés par le nombre de points demandés 10*n |

64 | la qualité Q des points obtenus sur les exercices. |

65 | </li> |
||
66 | </ul> |
||
67 | |||
68 | Si la note de qualité est inférieure à 1 pour un exercice, |
||
69 | I est mis à 0 pour cet exercice ; |
||
70 | si la note de qualité est comprise entre 1 et 2, |
||
71 | I est divisé par 2 lors du calcul de la note de la feuille. |
||
72 | |||
73 | </p><p> |
||
74 | Ces moyennes sont ramenées entre 0 et 1 et |
||
75 | la note de la feuille est calculée comme |
