<< Cosmo.CosmoTeaching %TOC% ---- ---+ how wims points are calculated - English see also - CosmoTeaching - WimsHowToCalculate5Points %STARTINCLUDE% ---+++ 5.0 grade points on WIMS - how it's calculated * You can get a grade of up to a maximum of 5.0 points from WIMS exercises: * %$ 0.0 \le 5 \frac{ \sum_{i=1,n} x_i q_i^{0.3} }{n} \le 5.0 $% where * %$ x_i $% is _the percentage done_ for a given "sheet" - let us normalise this to the range from 0.0 i 1.0 * %$ q_i $% is the "quality" - in the range from 0.0 to 1.0; the power of 0.3 implies that the effect of %$ q_i $% is weak unless the "quality" parameter is very low * how to check your current score: * *home* * *My scores* * _Global average: *something* out of 5._ Here, *something* is your total amount of points * The formula for a single exercise done <em>m</em> times, is %$q_m$% po _m_ razy, gdzie %$s_1, ..., s_m$%, which is in the range from 0.0 to 1.0. This is a decaying average, with %$q_m = \frac{0.85 q_{m-1} + s_m}{1.85}$%. In other words, the most recent tries at a realisation of an exercise have the most influence on the score for that exercise. * Chromium/Chrome bug: _As of 2020 to 2024, *%RED%chromium/chrome browser software has a bug%ENDCOLOR%* that prevents the display of some of the exercises. Firefox is one browser without the bug._ %STOPINCLUDE% <!-- * zrobienie ćwiczeń w wims można wykonać do daty negocjowanej z wykładowcą --> -- Main.BoudRoukema - 19 Feb 2024
