Using a personal digital assistant to increase independent task completion by students with autism spectrum disorder.

Three students with autism used a Palm Pilot loaded with cooking prompts. The device showed color photos, played short audio, and ran 30-second video clips with voice-over for each recipe step. Researchers measured how many steps each teen finished without adult help during three recipes in a school kitchen. They started with no device, then added the PDA, then took it away to see if skills stuck.

All three students jumped from about 30 % correct steps to over 90 % once the PDA was in their hands. When the device was removed two weeks later, they still hit 85 % correct. Teachers reported zero problem behavior during cooking for the first time all year.

Spanoudis et al. (2011) built on this work by adding auto-fade software so prompts slowly disappear; kids still succeeded even when prompts thinned to none. Szempruch et al. (1993) did the same idea with paper photos taped to a wall; the PDA simply digitizes that old trick. Spriggs et al. (2015) let parents shoot 30-second selfie videos on a tablet; one teen learned bus travel faster than these students learned recipes, showing the method scales to home life. Chang et al. (2011) swapped the handheld for a Kinect camera that tracks hand motion and speaks the next step; adults with ID no longer need to tap a screen, proving the concept works hands-free.

You can turn any tablet or phone into a portable job coach. Record the task once, load it in shuffle mode, and hand it to the learner. Start with full prompts, then fade to photos only, then remove the device. The skill stays, and you free up staff for other students.
