“…Skinner, Belfiore et al () demonstrated how precisely measuring learning rates allowed researchers to establish that the rapid rates of presentation (1 second) would result in more rapid increases in Bob's word reading. Other educators and researchers have conducted similar studies and shown that strategies and procedures that appear to enhance learning rates (when researchers evaluate them using crude measures of instructional time) actually retard learning (Cates et al, ; Joseph & Nist, ; Nist & Joseph, ; Schisler, Joseph, Konrad, & Alber‐Morgan, ; Skinner et al, ). Others have compared intervention effectiveness more precisely by holding instructional time constant across competing remedial procedures (e.g., Carroll, Skinner, Turner, McCallum, & Masters, ; Grafman & Cates, ; Poncy, Skinner, & Jaspers, ; Skinner et al, ).…”
