Abstract
Current conceptualizations of process quality in early childhood education highlight a variety of global classroom indicators that directly link to improved child outcomes. This conceptualization may need to be extended, however, to facilitate more meaningful change in children's development and readiness for kindergarten. To enhance our current definitions of process quality, we propose a set of more specific, observable adult interaction practice elements as a complement to existing global indicators within structural process elements and the broader preschool classroom ecology. We describe and define three practice types, as well as the individual practice elements within them, to include: (a) adult-led interaction practices, (b) child-led interaction practices, and (c) differentiated scaffolding. In operationalizing each practice element, we also provide empirical evidence as grounding for its inclusion in our conceptualization. We discuss implications and future practice and policy directions.
