Verb-marking errors such as "she play football" and "daddy singing" are a hallmark feature of English-speaking children's speech. We investigated the proposal that these errors are input-driven errors of commission arising from the high relative frequency of subject + unmarked verb sequences in well-formed child-directed…

This reflective piece tells the story of how I started out doing Conversation Analysis (CA) and have been transitioning into doing mixed methods for some years now. My basic argument is that language learning talk is too complex a phenomenon to analyse using a single methodology. Specifically, it is extremely difficult to isolate from the…

Previous research shows that infants of parents who are more likely to engage in socially contingent interactions with them tend to have larger vocabularies. An open question is "how" social contingency facilitates vocabulary growth. One possibility is that parents who speak in response to their infants more often produce larger…

The COVID-19 crisis was a global upheaval that significantly impacted the education systems--in the face of this, district and school leadership demonstrated remarkable resilience, overcoming the challenge of educating students through these uncertain times. They drew upon their existing leadership skills while also acquiring new ones they never…

An important aspect of a constructed language (conlang) is how it sounds when spoken. This dissertation designs and implements a tool to allow the user to hear how their conlang sounds when spoken. This tool will generate spoken language based on sample text in the constructed language. Further, it will enable the user to manipulate the phonetics…

Vocal exchanges are often comprised of responses under multiple sources of stimulus control. For example, a picture may contain multiple components, and an instructor may ask a learner to respond differentially to questions about the picture (e.g., "who," "what," "where," "color," "number,"…

Inclusive preschool classrooms have become increasingly common in recent decades, affording opportunities for children with and without disabilities opportunities to interact and develop positive relationships. Children with disabilities may be unintentionally excluded from these interactions due to communication differences. This paper discusses…

Purpose: This systematic review and meta-analysis estimates the overall language skills of youth offenders involved with the juvenile justice system. Given the importance of this population, identifying avenues through which we can increase the likelihood of successful interventions is a necessary societal effort. Method: Eighteen studies,…

Developing a sense of community (SoC) in college is vital due to its positive impacts on learning and student success. In this study, the researchers examine students' perceptions of SoC in synchronous and asynchronous online courses, with specific interest in the experiences of regional campus students who are often considered to be…

Mobile instant messengers such as WhatsApp have become an essential part of everyday life and can be a transformative tool for teacher professional development. Several studies have addressed the use of WhatsApp in a community of practices. However, there is a lack of study on examining teachers' interaction in WhatsApp community of practices,…

Contemporary science education frameworks identify computational thinking as an essential science and engineering practice that supports scientific sense-making and engineering design. Despite national emphasis on teaching science, engineering, and computational thinking (NGSS Lead States, 2013), little research has investigated the ways that…

Taking into account the facilitative role of mobile-mediated communication for promoting EFL learners' L2 development, this study investigated Iranian EFL learners' perceptions of recast and their modified output through face-to-face, audio, and video-based mobile-mediated communication. To this end, sixty intermediate EFL learners at two…

This paper, as part of a European Commission-funded project entitled REBEL (Repurposing Education through Blended Learning), deconstructs school communities understanding of the challenges and opportunities for blended learning in the school sector in Ireland with perceptions shaped by experiences of enforced school closures during the pandemic.…

This study investigated responsive and directive speech from 60 Finnish mothers to their 2-year-old children, as well as correlations with concurrent and later vocabulary. Possible gender differences with regard to both maternal speech and children's vocabulary skills were considered. There were no gender differences in maternal utterance…

Successful intervention outcomes and comprehensive assessment is important for people who rely on augmentative and alternative communication (AAC). However, the literature surrounding AAC assessment remains sparse. The purposes of this project were to describe the AAC assessment process followed by speech-language pathologists (SLPs) and to…
