This paper cites modest beneficial effects of early intervention for children with developmental disabilities or children at risk, and examines two specific program features, age of start and family involvement. The moderating influence of the level of disability severity is also analyzed, and future directions for improving early intervention…

Follow-up at age 9 of 141 children who had participated in either a mediated learning (ML) or direct instruction (DI) early intervention program found no main-effect differences between the 2 groups. Several significant aptitude-by-treatment interactions were found, with initially higher performing children gaining more from DI and initially lower…

The study evaluated developmental progress in three groups of infants (9-30 months) presenting Down syndrome (n=28), mild disability (n=16), or moderate/severe disabilities (n=16). To evaluate intervention impact, formulas that measure rate of development and change in rate of development were computed. Findings indicated rate change formulas were…

Twenty-nine elementary special education teachers each monitored 2 students with mild disabilities using curriculum-based measurement (CBM) for 16 weeks. Students whose teachers implemented CBM more accurately made significantly greater math gains than students whose teachers either implemented CBM less accurately or who did not use CBM. Adequacy…
