theories of evaluation

This has been written after continuously getting bad marks :) :)


Dice theory


Each professor does the marking individually for each student. It surely depends on the weight-age of the question- for example a 6 mark question would use a single dice throw and a 15 mark question would include a summation of 5 dice throws divided by 2.
There is surely a faster method to do it,” though I do not know the statistical validity of this one”.

Just throw a dice once and scale the marks to the total marks of the paper. With increasing time pressure this method will be in vogue a few months from despite not being as efficient as the earlier method.


Flash theory

As group work gains importance so do the chances of it being followed in all relevant fields, sadly even correcting answer sheets. The major focus is to save time and also change the arduous processes of marking into an interesting game.
This one is fairly straight-forward a bunch of people sit together to play a game of flash , only difference being , they bet on students marks instead of using money. Each person gets to evaluate one subject, thus the number of people gets restricted by the number of subjects available.
The number of bets should be a multiple of number of student as each bet decides marks of one student in all subjects. If the person desires a strict evaluation the marks are decided by the lowest value card, “each evaluator can chose different marking scheme”. If he chooses to be extra lenient then the highest value card gets in action.


The grand wheel of fortune


This is the simplest game for its not as tedious as dice game not as complicate das the flash game. This one’s simple and specially designed for the evaluators who either are too old to remember the rules and people who are simply bored of playing the dice game for ages.
This has variations for it can be played in any combination of subjects, students, professors………….
The bottomline stays that the marks will be decided by the spin of a wheel; still it provides enough room for the ‘STRICT’ evaluators to play with as in their case the size of sectors containing zeroes occupies larger space.


Dart board


Another reason why I like the grand wheel of fortune is that is can be used for the dartboard game too. Like others this has versions too concentric circles, sectors like wheel game or for art loving evaluators any arbitrary design they choose would decide the fate of students

Just plain bet


This is by far the fastest way to evaluate.
People simply bet on anything, literally anything. It may range from
“the time required by Rajnikant to catch a bullet is less or greater than (minus 2) seconds.”
Or it may be a simple one like cricket bets
“the persons score will be the number of runs Ganguly scores.”

Weight of the sheet

Oldest theory for globe courses.
The heavier the sheet, the better the marks.
Nothing more to explain.


Disclaimer:

If any of you students gets to choose the evaluation scheme, pick the grand wheel of fortune as it has a scope for fairness of evaluation.
Clause 0.123 of this game says if a student is dissatisfied with his marks then he can challenge the evaluator and if the challenge is upheld by a
‘FAIR INDEPENDENT BODY‘
then…………………..
