Endurance of multiplication fact fluency for students with attention deficit hyperactivity disorder.

Behav Modif 34(2):79-93 (2010) PMID 20308353

This study examines the relationship between a critical learning outcome of behavioral fluency and endurance, by comparing the effects of two practice procedures on multiplication facts two through nine. The first procedure, called whole time practice trial, consisted of an uninterrupted 1 minute practice time. The second procedure, endurance building practice trials, had three 20 second practice trials. A total of 3 students with attention deficit hyperactivity disorder participated. Results indicated that multiplication facts with the endurance building practice trials produced more efficient learning when compared to the whole time practice trial procedure for all 3 participants. Additionally, results show that even with the amount of practice time being equal, 1 minute in both conditions, on average participants practiced 30% more problems with the endurance building practice trials procedure than they did with the whole time practice trial procedure.
