Research indicates that readers break down complex words into their smallest, meaning-based units (morphemes) when spelling (e.g., Senechal, 2000). However, it remains unclear how morphemes are formed and whether newly formed morphological knowledge (i.e., knowledge of morphemes) is strong enough to support word learning. The current research…

This dissertation presents three studies that examined issues related to the production and the perception of pitch in a tone language. The first study examined linguistic contexts that may modulate consonant-induced pitch perturbations (CF0) in a tone language. Previous studies have produced mixed findings regarding the role of linguistic…

Lexical categories like noun and verb are foundational to language acquisition, but these categories do not come neatly packaged for the infant language learner. Some have proposed that infants can begin to solve this problem by tracking the frequent nonadjacent word (or morpheme) contexts of these categories. However, nonadjacent relationships…

This study investigated the instructional talk of three math teachers from two urban middle schools as they implemented a curriculum designed to develop students' knowledge of academic vocabulary and encourage word use during classroom discussions. Data were drawn from audio- and video-recordings, classroom observations, and teacher…

This study examined independent reading behaviors and contextual factors that contributed to growth in vocabulary and literacy of fourth grade English-only (EO), limited English proficient (LEP), and fluent English proficient (FEP) children. Participants were given pre-post measures of receptive and expressive vocabulary, word reading, decoding,…
