Teaching memorized spelling with a microcomputer: time delay and computer-assisted instruction.

Five special-education students practiced spelling words on a classroom computer. The program used constant time delay: the word appeared, then after a few seconds the correct spelling popped up if the student had not typed it.

Each session the computer ran the whole lesson and recorded every response. No adult had to sit beside the child or score trials.

Four of the five students learned all 18 words. They also spelled the same words correctly with pencil and paper, showing the skill carried over.

The computer kept perfect data, so teachers could see daily progress without extra work.

Vedora et al. (2007) later got the same good results with computer spelling lessons for teens with developmental disabilities. They swapped time delay for anagram and writing tasks, so the two studies act as conceptual replications.

Wacker et al. (1985) and Robertson et al. (2013) used microswitches to let students with profound disabilities turn on toys or music. The same idea—technology doing the work—shows up here: the computer handles prompts, timing, and data.

Moreno et al. (2005) moved beyond spelling and used computers to teach thinking skills to students with severe ID. Together these papers form a line: special-ed kids can learn academic, motor, or cognitive skills when a machine delivers the program.

If you run spelling programs in a resource room, load the words into any free time-delay app and let the computer teach while you rotate to other students. You get built-in trial counts, automatic prompting, and clean graphs at the end of the period.
