摘要：Two case studies were utilized to teach math skills while embedding the constant time delay teaching strategy. The study targeted children who were at risk for having mathematic difficulty in school due to disabilities, socioeconomic status, and living in a rural area. Four 3- to 5-year-old children with disabilities who attended rural inclusive preschool programs participated. Results indicated that early math skills were acquired with high levels of accuracy when compared with baseline data. Due to the end of the school year, one of the four children did not participate in maintenance or generalization data sessions. However, of the three children who participated, skills were maintained and/or generalized with 100% accuracy.
