Scorecalculation

Work in progress

This page will hold the score calculations used by the schoolsplay and childsplay activities.
I'm not sure if each activity should have a page of it's own or that we just put everything in one page.

For now I've just put the stuff here.

All score values must be between 0.2 and 10.0

---

Package: Childsplay_sp

Activity: find_char_sound

Data:

• Timespend, in seconds -> seconds
• Number of characters to find -> self.lencharslist

Calculation:

f = 1.4
score = max(0.2, (10 - (float(seconds) / float(self.lencharslist))*f / 2.0 + 1))

Activity: memory (all)

Data:

• Timespend, in seconds -> seconds
• Number of cards -> totalcards
• Number of cards shown more then one time -> cardsturnt

Calculation:

c = 0.7
f = 0.5
score = 8.0 / ( max( float(cardsturnt)/float(totalcards)/1.5, 1.0 ) )**c + 2.0 / ( max( seconds/(totalcards*2), 1.0)) **f

Activity: fallingletters

Data:

• Timespend, in seconds -> seconds
• For each wrong character -> + 10 seconds
• For each missed character -> + 40 seconds

Calculation:

c = 0.7
f = 0.6
score = max(0.2, 10 - ((((seconds/26.0)*c) ** f)-0.8))
