Effects of direct verbal instruction on intellectual development of institutionalized moderately retarded children: A 2-year study

Maggs, A.; Morath, P.
Abstract:
This study compared the effects of two programs on the language gains of students with moderate to severe mental retardation across two years of implementation: DISTAR Language and the Peabody Language Kit. Results indicate that students receiving instruction with DISTAR Language achieved significantly greater gains on all assessment measures than the control group. Additionally, DISTAR students progressed at approximately the same rate as typically developing children, gaining 22.5 mental age months across 24 months, whereas control students only gained 7.5 mental age months in the same period of time.
