An alternating treatments design was used to evaluate the effectiveness of
an educational program that combined timings (via chess clocks), peer tutor
ing (i.e., peer-delivered immediate feedback), positive-practice overcorrec
tion, and performance feedback on mathematics fluency (i.e., speed of accur
ate responding) in four elementary students with mathematics skills deficit
s. Results showed that both serving as a tutee (i.e., overt computation res
ponding) and as a tutor (i.e., delivering feedback) resulted in increased r
ates of accurate responding for three of the students. Furthermore, all fou
r students showed additional increases in fluency when performance feedback
was added. Results are discussed in terms of combining intervention compon
ents designed to increase accuracy and fluency.
