Well-developed lexical representations are important for reading comprehension, but there have been no prior attempts to track growth in the depth of knowledge of particular words. This article examines increases in depth of vocabulary knowledge in 4-5-year-old preschool students (n = 240) who participated in a vocabulary intervention that taught…

Comparing deaf and hard of hearing (DHH) children with their hearing peers in learning Chinese, the study tested the lexical quality hypothesis (Perfetti, 1992, 2007), which asserts the importance of building orthographic, phonological, and semantic connections in high-quality lexical representations. DHH children and hearing peers matched on…

Most vocabulary growth during the school-age years occurs incidentally. However, little is understood about the influence of language skills on word knowledge growth during reading. Using a pretest-posttest quasi-experimental design, we examined incidental word learning through reading, considering the presence/absence of supportive context and…

Lexicon Pirate was originally developed as a strategy intervention programme to treat lexical disorders of pre-school children. To evaluate the therapy's effectiveness for school-age students, a randomized controlled trial (RCT, N = 157) was conducted. Based on a pre--post-test design, the programme's impacts were compared with a control group…

The longitudinal intervention study reported here is the first to investigate the efficiency of computer learning software specifically designed for dyslexic Swiss German learners of Standard German as a second language (L2) and English as a third language (L3). A total of 40 subjects (20 of them dyslexics and 20 of them nondyslexics; 10 students…

For this project I worked with twelve of my fourth grade students from a local school in the southwestern part of Stokes County, North Carolina on increasing their vocabulary skills through the development and implementation of seven vocabulary strategies. During the Literature Review I came across the following seven strategies: Prediction;…

An experiment examined whether beginning readers can successfully learn to detect and define homonyms, and whether this ability correlates with vocabulary and/or phonological awareness. First graders received ambiguity instruction involving homonyms in isolation, in riddles, and in text. A control group received reading lessons without a…

This study considered the efficacy of a differentiated approach to vocabulary instruction for learners with word-finding difficulties (WFD) in the speech and language pathologist's room. Using a pretest-posttest design to study treatment outcomes, 10 second graders with WFD received first semantic-based vocabulary instruction (S) and then…

We trained 36 12-year-old Chinese students with reading disorders in the analysis, synthesis and integration of orthographic constituents of semantic and phonetic "bujians" (radicals); and also their writing (spelling and composing) skills. These target students were compared with 37 age-controls in a pre-test and post-test design on a…

An instructional strategy was investigated that addressed the needs of deaf and hard of hearing students through a conceptually based sign language vocabulary intervention. A single-subject multiple-baseline design was used to determine the effects of the vocabulary intervention on word recognition, production, and comprehension. Six students took…
