A design-based implementation study of a preschool Spanish/English multi-tiered language curriculum / Estudio de implementación basada en el diseño de un currículum preescolar multinivel inglés/español

Abstract

Implementation considerations should be integrated into the iterative development of educational innovations. The purpose of this design-based implementation research (DBIR) was to identify intervention components worthy of revision, examine the feasibility of a video manual and document barriers to the implementation of a multi-tiered dual-language instructional curriculum. Six teachers implemented the curriculum and provided feedback via structured interviews. Although four of the six teachers reported the intervention to be highly feasible, multi-tiered instruction did not align with the beliefs of two teachers. Teachers’ feedback combined with child-level narrative and vocabulary outcomes led to curriculum revisions and to the creation of additional implementation supports. Findings suggest system-level barriers influence the sustainability of multi-tiered instruction in early childhood settings.
