A mobile unit was used over a 2 1/2 month period to demonstrate that a mobile tutoring program for eight infants with Down's Syndrome (12 to 18 months old) had certain educational, economic, and logistical advantages. The vehicle and camper body were said to have been chosen according to the following criteria: sufficient height to permit an adult to stand without stooping, basic housekeeping and child care accommodations, a working area large enough to accommodate one child and one adult, and adequate lighting, heating and cooling apparatus. The program employed two undergraduate women selected because of their ability to relate to young children effectively, careful driving habits, excellent language skills, and willingness to help create and carefully implement lesson plans. The curriculum emphasized planned language stimulation through gamelike activities such as finger plays, music, art, tea parties, sandbox activities and water play. It was reported that seven of the eight children adapted readily to the new learning environment and that the cost of providing itinerant teaching services (3 hours per child per week) compared favorably with the usual cost of providing a public school teacher for homebound children.
