The effects of video modeling with voiceover instruction on accurate implementation of discrete-trial instruction.

Early et al. (2012) filmed a short video that shows every step of a discrete-trial lesson. A calm voiceover labels each move as it happens.

Staff watched the clip, then ran trials with real children who had developmental delays. The team tracked how closely staff matched the model.

After one viewing, staff hit high-fidelity scores and kept them for weeks. The children they taught also learned new skills faster.

No extra handouts, lectures, or live demos were needed. The video plus voice did the heavy lifting.

Shuler et al. (2019) used the same video-plus-voice package to teach supervisors how to give feedback. Both studies got quick, lasting gains, showing the method works across different staff skills.

Day-Watkins et al. (2018) added rehearsal and praise to the same clips. Their fidelity jumps were even larger, suggesting you can boost the effect by layering brief BST on top of the video.

Randell et al. (2007) taught DTT with computer simulation instead of video. Both routes worked, so you can pick the tech your team already likes.

You can email new hires a 10-minute clip tonight and see tighter trials tomorrow. No classroom time, no travel budget, no drift while you wait for the next in-service. If you want even stronger results, add a quick role-play and praise after the video, just like Day-Watkins did.
