St. Koscinski et Dl. Gast, USE OF CONSTANT-TIME DELAY IN TEACHING MULTIPLICATION FACTS TO STUDENTS WITH LEARNING-DISABILITIES, Journal of learning disabilities, 26(8), 1993, pp. 533
This study investigated the effectiveness and efficiency of a constant
time-delay procedure in teaching multiplication facts to three male a
nd two female elementary school students, aged 9 years 6 months to 12
years 5 months, identified as learning disabled. The five students wer
e taught unknown facts using a 4-second constant time-delay procedure.
Data were collected on generalization to a paper-and-pencil task, to
a horizontal display orientation, and to the reverse fact, as well as
incidentally acquired ability to solve missing-factor problems. Result
s indicated that the near-errorless learning procedure was effective a
nd efficient in teaching multiplication facts to students with learnin
g disabilities. Learning generalized to a paper-and-pencil task, to a
different presentation orientation, and to the reverse fact.
