Embodiments of the system and method present a stimulus-response pair to a student to obtain a binary response that is either correct or incorrect. The token is next presented to the student based on the student's response. If the response is correct, then the token is presented to the student based on the initial repetition interval without modification. If the response is incorrect, then the learnedness value is reset and the progression through the repetition intervals is restarted. In some embodiments, the initial repetition intervals are dynamically adjusted based on the student's response to obtain revised repetition intervals. This is achieved by manipulating the exponent of the mathematical term representing the curve of the repetition intervals. | 12-20-2012 |
