Reliability<br />

Reliability data were collected dur<strong>in</strong>g at least<br />

35% of all the experimental sessions. Interobserver<br />

reliability was calculated by us<strong>in</strong>g<br />

po<strong>in</strong>t by po<strong>in</strong>t method with a formula of the<br />

number of agreements divided by the number<br />

of agreements plus disagreements multiplied<br />

by 100 (Tawney & Gast, 1984).<br />

The mean percent of the <strong>in</strong>ter-observer<br />

agreement for the simple progression skill<br />

dur<strong>in</strong>g basel<strong>in</strong>e was 98% (90% to 100%); dur<strong>in</strong>g<br />

<strong>in</strong>struction was 93% (80% to 100%);<br />

dur<strong>in</strong>g ma<strong>in</strong>tenance was 100% <strong>and</strong> dur<strong>in</strong>g<br />

generalization was 96% (90% to 100%). Independent<br />

variable reliability (procedural reliability)<br />

was calculated by divid<strong>in</strong>g the number<br />

of teacher behaviors observed by the number<br />

of teacher behaviors planned <strong>and</strong> multiplied<br />

by 100 (Bill<strong>in</strong>gsley, White, & Munson, 1980).<br />

The follow<strong>in</strong>g teacher behaviors were observed<br />

for procedural reliability dur<strong>in</strong>g tra<strong>in</strong><strong>in</strong>g<br />

session: (a) hav<strong>in</strong>g the materials ready, (b)<br />

secur<strong>in</strong>g the participants attention, (c) deliver<strong>in</strong>g<br />

the task direction, (d) deliver<strong>in</strong>g the<br />

controll<strong>in</strong>g prompt <strong>in</strong> time (if appropriate),<br />

(e) wait<strong>in</strong>g for the response <strong>in</strong>terval, (f) deliver<strong>in</strong>g<br />

the correct behavioral consequences,<br />

(g) wait<strong>in</strong>g for the <strong>in</strong>ter-trail <strong>in</strong>terval. The<br />

same steps were observed dur<strong>in</strong>g probe, ma<strong>in</strong>tenance,<br />

<strong>and</strong> generalization sessions except<br />

for delivery of control prompts.<br />

Procedural reliability measures resulted <strong>in</strong><br />

an overall percentage of 100% dur<strong>in</strong>g basel<strong>in</strong>e<br />

for Ömer. Procedural reliability measures<br />

resulted <strong>in</strong> an overall percentage of 96% (87%<br />

to 100%) dur<strong>in</strong>g <strong>in</strong>struction for Ömer. This<br />

teacher implemented ma<strong>in</strong>tenance <strong>and</strong> generalization<br />

sessions with 100% accuracy for<br />

Ömer. Procedural reliability measures resulted<br />

<strong>in</strong> an overall percentage of 100% dur<strong>in</strong>g<br />

basel<strong>in</strong>e for Yener. Procedural reliability<br />

measures resulted <strong>in</strong> an overall percentage of<br />

98% (86% to 100%) dur<strong>in</strong>g <strong>in</strong>struction for<br />

Yener. This teacher implemented ma<strong>in</strong>tenance<br />

<strong>and</strong> generalization sessions with 100%<br />

accuracy for the lateral rotation skill. F<strong>in</strong>ally,<br />

procedural reliability measures resulted <strong>in</strong> an<br />

overall percentage of 100% dur<strong>in</strong>g basel<strong>in</strong>e<br />

for Soner. Procedural reliability measures re-<br />

sulted <strong>in</strong> an overall percentage of 95% (80%<br />

to 100%) dur<strong>in</strong>g <strong>in</strong>struction for Soner. Also,<br />

this teacher implemented ma<strong>in</strong>tenance <strong>and</strong><br />

generalization sessions with 100% accuracy.<br />

Ma<strong>in</strong>tenance <strong>and</strong> Generalization Sessions<br />

Ma<strong>in</strong>tenance sessions were collected two, <strong>and</strong><br />

four weeks after the <strong>in</strong>struction had stopped.<br />

Ma<strong>in</strong>tenance data showed that the participants<br />

ma<strong>in</strong>ta<strong>in</strong>ed the rotation skills taught to<br />

them at criterion level one, two, <strong>and</strong> four<br />

weeks after the <strong>in</strong>struction. Generalization<br />

across persons was exam<strong>in</strong>ed by a pre-post test<br />

design. These sessions occurred before tra<strong>in</strong><strong>in</strong>g<br />

<strong>and</strong> at the end of teach<strong>in</strong>g the simple<br />

swimm<strong>in</strong>g skills. Generalization sessions were<br />

identical basel<strong>in</strong>e but <strong>in</strong> another sett<strong>in</strong>gs. One<br />

to one teach<strong>in</strong>g arrangement <strong>and</strong> s<strong>in</strong>gle opportunity<br />

methods were used dur<strong>in</strong>g both<br />

ma<strong>in</strong>tenance <strong>and</strong> generalization. Generalization<br />

data showed that all participants reta<strong>in</strong>ed<br />

the simple swimm<strong>in</strong>g skills taught to them<br />

across people 100%.<br />

Results<br />

Most to Least Prompt<strong>in</strong>g Instructional Data<br />

Table 2 shows <strong>in</strong>structional data for each student<br />

through the criterion. Ömer, Yener, <strong>and</strong><br />

Soner needed 9 tra<strong>in</strong><strong>in</strong>g sessions to reach criterion<br />

on simple progression swimm<strong>in</strong>g skill.<br />

Basel<strong>in</strong>e <strong>and</strong> tra<strong>in</strong><strong>in</strong>g data for Ömer, Yener<br />

<strong>and</strong> Soner shown <strong>in</strong> Figure 1 respectively.<br />

The open circles represent the percentage<br />

of correct respond<strong>in</strong>g dur<strong>in</strong>g full basel<strong>in</strong>e <strong>and</strong><br />

<strong>in</strong>sturtional sessions, ma<strong>in</strong>tenance <strong>and</strong> generalization<br />

session. As seen <strong>in</strong> Figure 1, all subjects<br />

meet criteria after the <strong>in</strong>troduction of<br />

most to least prompt<strong>in</strong>g. This data showed<br />

that most-to-least prompt<strong>in</strong>g was effective on<br />

teach<strong>in</strong>g simple progression swimm<strong>in</strong>g skill<br />

for children with autism.<br />

Ömer, Yener, Soner performed no correct<br />

responses dur<strong>in</strong>g the basel<strong>in</strong>e sessions. When<br />

<strong>in</strong>struction of the simple progression us<strong>in</strong>g<br />

“physical prompt <strong>and</strong> verbal prompt” started,<br />

they performed with 100% accuracy <strong>in</strong> the<br />

first three session, <strong>and</strong> cont<strong>in</strong>ued the performance<br />

(100 %) while us<strong>in</strong>g “verbal <strong>and</strong> gesture/prompt”<br />

<strong>in</strong> sessions 4, 5, 6. All subjects’<br />

performance cont<strong>in</strong>ued 100% <strong>in</strong> sessions 7, 8,<br />
