In this dissertation, I present the findings from the implementation of an informational text reading comprehension intervention. Using a single-case multiple baselines across participants' experimental design, I examined results from three small heterogeneous groups of three to four students during the literacy block in a suburban fourth-grade…

In response to the calls for making key stakeholders' perspectives relevant in the test validation process, the study discussed in this report sought test-taker feedback as part of collecting validity evidence and supporting the ongoing field testing efforts of the new "TOEFL ITP"® Speaking section. Specifically, I aimed to investigate…

Children with autism spectrum disorder (ASD) and hyperlexia (HPL) have both advanced word reading skills and a reading comprehension disorder, alongside impaired oral language. We developed a unique, parent-supported, tablet-based intervention aiming to improve oral and reading comprehension at the word-, phrase- and sentence-level, for…

In theory, teacher knowledge predicts instructional practice, thus impacting student outcomes. When it comes to knowledge to teach elementary-grade reading, most previous surveys have focused on knowledge essential for word reading development; few surveys have provided a picture of educator knowledge to teach both word reading and language…

Efforts to improve classroom language practices and children's language learning, as a means of supporting reading comprehension, may depend on teachers' knowledge about language structures and language development. To date, however, educational researchers and teacher educators have little understanding about teachers' knowledge about oral…

Purpose: The ability to identify children early in development who are at substantial risk for language/literacy difficulties would have great benefit both for the children and for the educational and therapeutic institutions that serve them. Information that is relatively easily available prior to the age of 3 years, such as late talking, family…

Background: Reading comprehension is a complex process influenced by many factors. However, the abilities that are known to influence reading comprehension may not contribute equally for children with different levels of oral language. Aims: Here we examined the relationship of two factors known to influence reading comprehension (morphology and…

Research with school-age readers suggests that the contributions of reading and language skills vary across reading comprehension assessments and proficiency levels. With a sample of 168 struggling adult readers, we estimated the explanatory effects of decoding, oral vocabulary, listening comprehension, fluency, background knowledge, and…

In contrast to the large body of research investigating intervention for poor decoding skills, far fewer studies have evaluated interventions for reading comprehension. There is even less research on children with more specific difficulties with reading comprehension, often referred to as "poor comprehenders". Levels of effectiveness…

Background: Syntax is a language skill purported to support children's reading comprehension. However, researchers who have examined whether children with average and below-average reading comprehension score significantly different on spoken-syntax assessments report inconsistent results. Aims: To determine if differences in how syntax is…

This study examined the sources of reading comprehension difficulties in English language learners (ELLs). The characteristics of ELL poor comprehenders were compared to their English as a first language (EL1) peers. Participants included 124 ELLs who spoke Chinese as an L1 and 79 EL1 students. Using a regression technique based on age, non-verbal…

In this study, an educational development approach is investigated aiming at improving reading comprehension outcomes in primary education through inquiry and design-based Science & Technology teaching. The context is societal pressure to increase the likelihood that more students, later in their life, will aspire for careers in…

The use of integrated tasks to test English-speaking skills raises questions about the impact of comprehension on test score outcomes, and the impact of stimulus materials on test-taker strategic behaviours. This study analysed speaking performances and verbal report data to examine the strategies used by test takers at different levels of…

This study investigated the relationship between listening comprehension and reading comprehension to determine if environmental factors might be contributing to a possible change in the equalization age for these two comprehension modalities from what was theorized by Thomas Sticht. The study employed a counterbalanced design to measure the…
