Teaching pedestrian skills to retarded persons: generalization from the classroom to the natural environment.

Five students with intellectual disability practiced crossing streets on a tabletop city model in class.

The model had roads, crosswalks, and tiny cars. Staff used praise and tokens when students looked both ways and waited.

Researchers tracked the same skills on real streets near school to see if classroom practice carried over.

All five students learned the five key steps: stop at curb, look left-right-left, wait for traffic, walk, keep looking.

When tested at real intersections, the students used the same steps without extra teaching. Skills stayed high weeks later.

Gayle et al. (2025) swapped the tabletop city for VR headsets with autistic kids and got the same strong generalization.

Sureshkumar et al. (2024) used video prompts on Zoom to teach first-aid safety to children with IDD. All three studies show tech updates keep the core idea: safe practice in a fake setting moves to the real world.

Annable et al. (1979) used the same multiple-baseline design to teach sewing instead of street crossing. Both prove the design works for life skills with students who have intellectual disability.

You can run this lesson anywhere. A taped-off floor and toy cars are enough. Teach the five look-and-walk steps, reinforce heavily, then probe on the nearest sidewalk. The 1976 paper gives you the task analysis; the newer VR and video studies remind us the medium can change, but the teaching logic stays the same.
