A comparison of video modeling with in vivo modeling for teaching children with autism.
Short clips of peers beat live demos for speed and generalization when teaching kids with autism.
01Research in Context
What this study did
The team taught five children with autism the same daily-living skill.
Half the kids first watched a short video of another child doing the task.
The other half first watched a live person do the same task.
They counted how many tries each child needed to master the skill.
What they found
Video modeling won.
Kids who watched the video learned the skill faster and used it in new places.
Live modeling still worked, but it took more trials and did not spread as far.
How this fits with other research
Bailey et al. (2010) asked the same question ten years later and saw no difference.
Their three children learned equally fast and liked both formats.
The 2000 study used tighter mastery rules and measured generalization; the 2010 study did not.
That small change may explain the clash.
Two big meta-analyses back the 2000 result.
Hong et al. (2016) and Storch et al. (2012) both show video modeling gives a solid, steady boost across dozens of single-case reports.
Petry et al. (2007) and MacDonald et al. (2009) then stretched the tool into harder areas like social play and pretend sequences, and it still worked.
Why it matters
You now have a cheap, repeatable teaching aid that beats live demos.
Film a peer once, play it many times, and watch skills travel to new rooms, people, and materials.
If a learner stalls, check your mastery criterion before you blame the model.

03Original abstract
The present study was designed to compare the effectiveness of video modeling with in vivo modeling for teaching developmental skills to children with autism. A multiple baseline design across five children and within child across the two modeling conditions (video and in vivo) and across tasks was used. Each child was presented two similar tasks from his or her curriculum; one task was used for the video condition, while the other was used for the in vivo condition. Video modeling consisted of each child watching a videotape of models performing the target behavior, whereas in vivo modeling consisted of the children observing live models perform the target behavior. After the observations, children were tested for acquisition and generalization of target behaviors. Results suggest that video modeling led to faster acquisition of tasks than in vivo modeling and was effective in promoting generalization. Results are discussed in terms of video modeling's motivating and attention maintaining qualities.
