The purpose of this study was to support teachers' child-directed language and student outcomes by enhancing the educative features of an intervention targeted to vocabulary, conceptual development and comprehension. Using a set of design heuristics (Davis & Krajcik, 2005), our goal was to support teachers' professional development within the…

Classic studies of educational media have demonstrated that children can engage in quick, incidental word learning on the basis of a single exposure of a program. Since most words are learned from context, a lingering question has been whether the kind of contextual support affects word learning. Using a within-subjects design this study examined…

To examine this hypothesis, this study analyzes whether comprehensible input in the form of captioned television…

Developing a large and rich vocabulary is central to learning to read. Children must know the words that make up written texts in order to understand them, especially as the vocabulary demands of content-related materials increase in the upper grades. Studies have documented that the size of a person's vocabulary is strongly related to how…

The purpose of this study was to examine the hypothesis that helping preschoolers learn words through categorization may enhance their ability to retain words and their conceptual properties, acting as a bootstrap for self-learning. We examined this hypothesis by investigating the effects of the World of Words instructional program, a supplemental…
