“…Skill mastery requires students to be both accurate and rapid (Haring & Eaton, 1978; Skinner, 1998). Although a variety of instructional techniques can be used to improve students’ accuracy, providing more opportunities to practice (also referred to as increasing learning trials [Albers & Greer, 1991; Belfiore, Skinner, & Ferkis, 1995], increasing opportunities to respond [Greenwood et al, 1987; Skinner, Turco, Beatty, & Rasavage, 1989], and/or increasing academic learning time [Berliner, 1984; Rosenshine & Berliner, 1978]) may be the most common procedures for increasing speed of accurate responding (Haring & Eaton, 1978; Skinner, Logan, Robinson, & Robinson, 1998). In addition to increasing rates of accurate responding or fluency, increasing opportunities to respond has also been used to facilitate skill maintenance and generalization (Ivarie, 1986; Skinner, 1998).…”
