Argumentation is an important mathematical practice, highlighted by research and policy documents that describe ways to structure reform-oriented classrooms (Nardi and Knuth 2017; NCTM 2000; NGA Center and CCSSI 2010). Participating in argumentation can enhance students' mathematics learning as they make sense of mathematical ideas, provide…

Background: Phonological processing skills have been found to contribute to spelling development across different orthographies; however, less is known about the role of orthographic knowledge. This longitudinal study explores the contribution of phonological and orthographic knowledge to spelling development in a semi-transparent orthography…

Previous research making claims about students' proving capabilities usually only explored one modality (e.g. oral or written arguments). This study compares the written and oral representations of eighth-grade students' mathematical arguments to determine whether the two modalities portray similar understandings. We replicate Stylianides' (2019)…

Purpose: In spite of improvements in language outcomes for children with hearing loss (HL) arising from cochlear implants (CIs), these children can falter when it comes to academic achievement, especially in higher grades. Given that writing becomes increasingly relevant to educational pursuits as children progress through school, this study…

This dissertation study aims to theorize an instructional practice which I labeled languaging thinking. Languaging thinking is conceptualized as a social practice in which teachers and students make visible and discuss how to think about a particular task, topic, or activity, through the use of spoken and written language and related semiotic…

Computer scientists and educational researchers evaluated effectiveness of computerized instruction tailored to evidence-based impairments in specific learning disabilities (SLDs) in students in grades 4-9 with persisting SLDs despite prior extra help. Following comprehensive, evidence-based differential diagnosis for dysgraphia (impaired…

In Study 1, children in grades 4-9 (N = 88, 29 females and 59 males) with persisting reading and/or writing disabilities, despite considerable prior specialized instruction in and out of school, were given an evidence-based comprehensive assessment battery at the university while parents completed questionnaires regarding past and current history…

This facilitator's guide is designed to assist professional learning communities (PLCs) in applying evidence-based strategies to help K-8 English learners acquire the language and literacy skills needed to succeed academically. Through this collaborative learning experience, educators will expand their knowledge base as they read, discuss, share,…

These handouts, which are meant to accompany the facilitator's guide, are designed to assist professional learning communities (PLCs) in applying evidence-based strategies to help K-8 English learners acquire the language and literacy skills needed to succeed academically. The facilitator's guide uses a five-step process for collaborative…

Interest in students who exhibit characteristics with difficulties in learning can be traced as far back as 1800. In order to better understand the complexities and causes of learning disabilities, many researchers (Bannatyne, 1968, 1974; Rugal, 1974) have investigated ways to better identify learners who struggle with academics. A strong argument…

This textbook covers two years' work intended for grades seven and eight. The book is divided into approximately 150 carefully planned lessons for each year's work. These lessons are grouped into chapters, each composed of a series of related units that center on a common theme. The material on which conversation and written exercises are based…
