Purpose: The first purpose of this study was to investigate how children's knowledge of taught words and transfer words assessed 10 months after a morphological vocabulary intervention can be predicted by means of language measures taken before the intervention. The second purpose was to investigate whether and how immediate post-intervention…

This within-subjects experimental study investigated the relative effects of word reading and word meaning instruction (WR+WM) compared to word-reading instruction alone (WR) on the accuracy, fluency, and word meaning knowledge of 4th-5th graders with dyslexia. We matched word lists on syllables, phonemes, frequency, number of definitions, and…

Deaf and hard of hearing (DHH) students face great challenges in becoming proficient readers. Vocabulary knowledge is consistently considered to be an important factor affecting DHH students' reading ability. However, the mechanism that underlies the relationship between vocabulary knowledge and reading comprehension in DHH students remains…

This article reports on a 3-year formative experiment involving the implementation and testing of a long-term, multifaceted vocabulary instruction program in fourth- and fifth-grade classrooms in three demographically distinct schools. The quantitative findings indicate that the students, across the 3 years of the project, showed accelerated…

Stealth assessment has been successfully embedded in educational games to measure students' learning in an unobtrusive and supportive way. This study explored the possibility of applying stealth assessment in a digital reading platform and sought to identify potential in-system indicators of students' digital learning outcomes. Utilizing the user…

This study explores reader, word, and learning activity characteristics related to vocabulary learning for 202 fifth and sixth graders (N = 118 and 84, respectively) learning 16 words. Three measures of word knowledge were used: multiple-choice definition knowledge, self-report of meaning knowledge, and production of morphologically related words.…

In this study, we examined 5th grade students' levels of vocabulary knowledge and syntactic awareness relative to their reading comprehension performance. The aim was to explore the contributions of vocabulary and syntactic awareness as potential sources of reading comprehension difficulty for these readers. Overall, we found that both vocabulary…

Purpose: To address the problem of low reading comprehension scores among children with hearing impairment, it is necessary to have a better understanding of their reading vocabulary. In this study, the authors investigated whether task and word type differentiate the reading vocabulary knowledge of children with and without severe hearing loss.…

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…

Morphological skills have been associated with performance on multiple literacy outcomes. While growth in derived word knowledge has been documented during mid-elementary grades, little research has studied the development of knowledge of specific morphemes, separate from whole-word knowledge. This study examined the development of knowledge of a…

"Time to Act," a 2009 report of the Carnegie Corporation's Council on Advancing Adolescent Literacy, concludes that U.S. students are ill-prepared for the literacy challenges of 21st century higher education, employment, and citizenship. Word Generation (WG) is a research-based vocabulary program for middle school students designed to…

Within a response to intervention (RTI) framework, students are typically identified as "academically at-risk" if they score below a specified cut-point on a benchmark screener. Students identified as at-risk are provided with an intervention intended to increase achievement. In the following technical report, we describe a process for…

This technical report presents results from a cross-validation study designed to identify optimal cut scores when using easyCBM[R] reading tests in Washington state. The cross-validation study analyzes data from the 2009-2010 academic year for easyCBM[R] reading measures. A sample of approximately 900 students per grade, randomly split into two…

This paper tracks the increase in the overall word reception knowledge of 224 young pupils in their 4th, 5th and 6th grades of primary education and in their 1st year of secondary education (7th grade), who learn EFL in a formal context. The 2,000 word frequency band of The Vocabulary Levels Test (Schmitt, Schmitt and Clapham, 2001, version 2) is…

The sheer quantity of words known (breadth) is strongly predictive of reading comprehension, yet little is understood about how quality of word knowledge (depth) affects comprehension. A group of 35 bilingual and monolingual 5th-grade students worked on developing depth of knowledge of 8 words, culminating in an activity in which the students…
