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

8 | sheet: a percentage of points obtained with respect to the number of points |
||
3929 | bpr | 9 | required, and the quality of points obtained on the exercises of the worksheet. |
23 | reyssat | 10 | Let x be the percentage and y the quality, both scaled proportionally |
11 | to values between 0 and 1. Here are the formulas for the computation of the |

7901 | bpr | 36 | Remark : For level 0 and 1, if the quality of points is less than 1 for an |
3571 | bpr | 37 | exercise, the percentage of points obtained |
7901 | bpr | 38 | become 0% for this exercise when x is computed ; if the quality of points is betwwen 1 and 2, |
3571 | bpr | 39 | the percentage of points obtained for this exercise is divided by 2 |
40 | when x is computed. |

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

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

60 | </li> |
||
61 | </ul> |
||
62 | |||
63 | Si la note de qualité est inférieure à 1 pour un exercice, |
||
64 | I est mis à 0 pour cet exercice ; |
||
65 | si la note de qualité est comprise entre 1 et 2, |
||
66 | I est divisé par 2 lors du calcul de la note de la feuille. |
||
67 | |||
68 | </p><p> |
||
69 | Ces moyennes sont ramenées entre 0 et 1 et |
||
70 | la note de la feuille est calculée comme |
