Gb. Biederman et al., VERBAL PROMPTING, HAND-OVER-HAND INSTRUCTION, AND PASSIVE OBSERVATIONIN TEACHING-CHILDREN WITH DEVELOPMENT DISABILITIES, Exceptional children, 64(4), 1998, pp. 503-511
In hand-over-hand modeling with response-contingent verbal prompts, ta
sks are divided into identifiable sequential components, and the achie
vement of each component is marked by, the delivery of some form of ve
rbal prompt. In a within-subjects design, children were trained in one
skill with I response-contingent verbal prompts and in a second skill
with simple passive observation. A separate group of children were tr
ained with less rigorous verbal prompting in one skill and With passiv
e observation in a second Consistent with previous research, we found
that passive modeling was overall significantly more effect;ve than ha
nd-over-hand modeling and that passive modeling was significantly, mor
e effective than hand-over-hand modeling with response-contingent prom
pting. Our evidence therefore indicates that current methods for teach
ing basic skills to children with severe developmental delays may requ
ire reassessment because simple observation of modeled skills appears
to be more effective than more labor-intensive instruction.
