“…For example, Carnine (1976) demonstrated that pacing in Direct Instruction (i.e., the rate of lesson presentation controlled by the teacher) produced high levels of student participation, correct responding, and student attention. Similarly, high levels of academic responding have been reported as characteristic of peer tutoring, due to the increased rate of task presentation, tutors calling for and prompting responses, and the use of immediate error correction (Delquadri,Greenwood,Stretton,& Hall,521 19841 171, [521][522][523][524][525][526][527][528][529][530][531][532][533][534][535][536][537][538] NUMBER4 (wiNm 1984) 1983; Dineen, Clark, & Risley, 1977;Trovato & Bucher, 1980). In PSI, study objectives, student access to course materials, frequent test taking, and frequent interactions with proctors have been related to increased study time and greater student engagement with course content (Born, Gledhill, & Davis, 1972;Born & Herbert, 1971;Kirigin, Braukmann, Atwater, & Wolf, 1982;Semb, Hopkins, & Hursh, 1973).…”
