Background: More limited working memory capacity and slower processing for language and cognitive tasks are characteristics of many children with language difficulties. Individual differences in processing speed have not consistently been found to predict language ability or severity of language impairment. There are conflicting views on whether…

We examined the cross-lagged relations between children's task-avoidant behavior and their performance in reading and spelling in Chinese. Eighty Grade 2 and 103 Grade 4 Mandarin-speaking Taiwanese children were assessed on measures of nonverbal IQ, task value, reading accuracy, fluency, and spelling. A year later, the children were reassessed on…

This dissertation investigates how the Taiwanese Tone Sandhi Groups are perceived, and the acoustic/phonetics correlates of listeners' judgments. A series of perception experiments have been conducted to scrutinize the following topics--Taiwanese tone neutralization, Tone Sandhi Group (TSG) as a prosodic domain, perceived boundary strength in…

There is extensive research on the benefits of making data-informed decisions to improve learning, but these benefits rely on the data being effectively interpreted. Despite educators' above-average intellect and education levels, there is evidence many educators routinely misinterpret student data. Data analysis problems persist even at districts…

The purpose of this study was to examine the effects of PECS phase III application training on independent mands in young children with autism. Participants were five children with autism ranging from ages 2 to 4 years old. A multiple baseline across participants was used to evaluate acquisition of independent correct mands across baseline and…

States and districts have launched unprecedented efforts in recent years to build new feedback and evaluation systems that support teacher growth and development. These systems depend on trustworthy information about teaching effectiveness--information that recognizes the complexity of teaching and is trusted by both teachers and administrators.…

Previous research has indicated that the classification of intellectual disability (ID) may negatively impact interpretations of the cognitive performance of children with ID, especially for general-education teachers. However, there are some findings that suggest that these negative effects of classification may be overcome when competing…

This study explored how a teaching experiment, which taught double counting with a constructive task assignment according to an ongoing assessment, helped students with mathematics difficulties develop their multiplicative reasoning skills. The participants were two fifth graders with math learning disabilities and one at risk. A micro-genetic…

Authenticity is a key to using technology for instruction in ways that enhance learning and support learning transfer. Simply put, a representation is authentic when it shows learners clearly what a task, context, or experience will be like in real practice. More authentic representations help people learn and understand better. They support…

We had 3 aims in the present study: (a) to examine the dimensionality of various evaluative approaches to scoring writing samples (e.g., quality, productivity, and curriculum-based measurement [CBM] writing scoring), (b) to investigate unique language and cognitive predictors of the identified dimensions, and (c) to examine gender gap in the…

The ability to recognise words from the aural modality is a critical aspect of successful second language (L2) listening comprehension. However, little research has been reported on computer-mediated development of L2 word recognition from speech in L2 learning contexts. This report describes the development of an innovative computer application…

The curriculum for teaching undergraduate university students in Iran majoring in English generally includes paragraph writing in the second year and essay writing (4-5 paragraphs) in the third year. The first-year course 'Grammar and Writing (I & II)' offered in two consecutive semesters covers grammar only, despite the inclusion of writing…

This study examined the relationship between the 2013 New Jersey High School Proficiency Assessment (HSPA) Language Arts and Mathematics scores and school level data related to family human capital and community social capital found in the extant literature to influence student achievement on high-stakes standardized assessments. School level data…

This study investigated the development of representational competence among organic chemistry students by using 3D (concrete and virtual) models as aids for teaching students to translate between multiple 2D diagrams. In 2 experiments, students translated between different diagrams of molecules and received verbal feedback in 1 of the following 3…

This study examined the predictive validity of curriculum-based measures in reading for Spanish-speaking English learners (ELs) at various levels of English proficiency. Third-grade Spanish-speaking EL students were screened during the fall using DIBELS Oral Reading Fluency (DORF) and Daze. Predictive validity was examined in relation to spring…
