As K-12 classrooms in the U.S. grow in linguistic diversity, there is a need to develop and evaluate the effects of instructional approaches that build knowledge of academic vocabulary for multilingual learners. While multimedia vocabulary instruction may represent a promising avenue for improving word learning for linguistically diverse…

Morphological knowledge refers to an individual's understanding of the structure and meaning of words based on their familiarity with morphemes (i.e., word parts, including prefixes, suffixes, and bases). This knowledge is crucial to developing various aspects of language and literacy to successfully function in 21st century education and…

Word semantic knowledge (WSK) is crucial to the development of one's reading comprehension ability. A total of 608 students (208 poor readers in the experimental group and 200 poor readers in the control group one, and 200 typical readers in control group 2) from grade 4 participated in this study. Selected reading ability assessments were…

Reader's Theater is a transformative and influential instructional tool for reading with far-reaching benefits for all students. Teachers are critical players in the use of Readers Theater in classroom; the effects of Reader's Theater are a direct result of a teacher's involvement. These effects include an increase in word recognition, fluency,…

Purpose: This study sought to identify an adequate intensity of interactive book reading for new word learning by children with specific language impairment (SLI) and to examine variability in treatment response. Method: An escalation design adapted from nontoxic drug trials (Hunsberger, Rubinstein, Dancey, & Korn, 2005) was used in this Phase…

There is growing recognition of the need to end the debate regarding reading instruction in favor of an approach that provides a solid foundation in phonics and other underlying language skills to become expert readers. We advance this agenda by providing evidence of specific effects of instruction focused primarily on the written code or on…

This paper is based on the first author's extensive examination of her teaching and her students' learning in a senior high school Biology classroom at a coeducational K-12 independent college in Victoria, Australia, over a five-year period. Research was guided by the following questions: (1) How can students become more aware of the specific…

Direct vocabulary instruction of Tier 2 and Tier 3 words in intermediate-grade curricula is an important tool of literacy instruction because English is a language grafted from many roots and has not developed a one-to-one phoneme-grapheme correspondence. In addition to knowing graphemes and phonemes, students must formally learn words that cross…

In this thesis, I present three related papers that collectively investigate the instructional supports on screen and in the media viewing context that influenced English and heritage language vocabulary knowledge in DLLs. In study 1, I examine how specific pedagogical approaches used in educational media might benefit DLLs. In study 2, I…

A quasi-experimental study examined effects of a 10-week word structure intervention with fourth-grade students. During daily 10-15-minute practice periods, students worked individually with mobile apps focused on specific aspects of word identification. Pre- and post-treatment assessments showed no differences in rate and accuracy of oral reading…

The ability to flexibly approach the pronunciation of unknown words, or set "for variability", has been shown to contribute to word recognition skills. However, this is the first study that has attempted to teach students strategies for increasing their set for variability. Beginning readers (N = 15) were instructed to correct oral…

Vocabulary instruction during English language learning was observed for one week in six classrooms (three K2 classes for four-year olds and three K3 classes for five-year olds) from three kindergartens in two districts of Hong Kong. From 23 sessions of observations and 535 minutes of data, field notes were coded to identify instances of…

Many preschool language-focused interventions attempt to boost language and literacy skills in young children at risk in these areas of development, though the long-term effects of such interventions are not well-established. This study investigated kindergarten language and reading skills, specifically the subcomponents of vocabulary, decoding,…

Two ways of measuring change are presented and compared: A conventional "change score", defined as the difference between scores before and after an interim period, and a process-oriented approach focusing on detailed analysis of conceptually defined response patterns. The validity of the two approaches was investigated. Vocabulary…

Almost fifteen years have passed since the publication of the National Research Council's seminal report "Preventing Reading Difficulties in Young Children," which provided research-based recommendations on what could be done to better position students in pre-kindergarten through third grade for success in grade four and above. This article by…
