iKnowIt is designed around Psychological findings for optimum memorization techniques!

1. •Memory retention (memorization) decreases with time.
   

iKnowIt’s calculations are based on Ebbinghaus’ forgetting curve.

Ebbinghaus’ forgetting curve

1. •Repetition strengthens long term memory.
   

2. •The strengthening decreases with increasing number of repetitions.
   

iKnowIt models these facts in its calculations.

Repetition

1. •Memory strengthening by repetition requires intervening items between repetitions.
   

2. •Differing learning contexts improve memorization.
   

iKnowIt chooses next associations to be tested and offered answers based on these facts.

Intervening items and learning context

1. •Reward improves learning.
   

iKnowIt rewards successful practices with gem stones.

Reward

1. •Memorization is most efficient when repetition intervals increase with time.
   

2. •After 6 repetitions memorization improvement is weak and memory is long lasting.
   

iKnowIt offers cards after most efficient repetition intervals.

6 successful repetitions are indicated by a special gem stone.
