Figure 2. Percent of correct resp<strong>on</strong>ses for Charlie <strong>and</strong> J<strong>on</strong>ah during baseline, interventi<strong>on</strong>, <strong>and</strong> maintenance<br />

sessi<strong>on</strong>s.<br />

with discrete tasks, results of this study extend<br />

<str<strong>on</strong>g>the</str<strong>on</strong>g> expectati<strong>on</strong>s of peer tutors’ abilities to<br />

chained task instructi<strong>on</strong>, increasing <str<strong>on</strong>g>the</str<strong>on</strong>g>ir versatility<br />

in <str<strong>on</strong>g>the</str<strong>on</strong>g> classroom.<br />

The sec<strong>on</strong>d research questi<strong>on</strong> addressed<br />

<str<strong>on</strong>g>the</str<strong>on</strong>g> degree of reliability with which peer tutors<br />

could implement c<strong>on</strong>stant time delay in teaching<br />

chained tasks. Dependent variable reliability<br />

data indicate that overall peer tutors collected<br />

student resp<strong>on</strong>se data with 98%<br />

agreement (range 94-100%) with <str<strong>on</strong>g>the</str<strong>on</strong>g> reliability<br />

observer. Peer tutors as a whole were<br />

able to implement <str<strong>on</strong>g>the</str<strong>on</strong>g> resp<strong>on</strong>se prompting<br />

strategy with 93% accuracy (range 84-99%).<br />

Wolery, Bailey, <strong>and</strong> Sugai (1988) state reliability<br />

above 90% is desirable, above 80% is acceptable.<br />

Nine out of <str<strong>on</strong>g>the</str<strong>on</strong>g> 11 peer tutors performed<br />

<str<strong>on</strong>g>the</str<strong>on</strong>g> steps of <str<strong>on</strong>g>the</str<strong>on</strong>g> c<strong>on</strong>stant time delay<br />

procedure with 90% or better accuracy.<br />

Results of <str<strong>on</strong>g>the</str<strong>on</strong>g> peer tutoring reliability data<br />
