Research on "parentese," the acoustically exaggerated, slower, and higher-pitched speech directed toward infants, has mostly focused on maternal contributions, although it has long been known that fathers also produce parentese. Given recent societal changes in family dynamics, it is necessary to revise these mother-centered models of…

Children learn language by listening to speech from caregivers around them. However, the type and quantity of speech input that children are exposed to change throughout early childhood in ways that are poorly understood due to the small samples (few participants, limited hours of observation) typically available in developmental psychology. Here…

How does one assess developmental change when the measures themselves change with development? Most developmental studies of word learning use either looking (infants) or pointing (preschoolers and older). With little empirical evidence of the relationship between the two measures, developmental change is difficult to assess. This paper analyzes…

Purpose: This study examined science achievement; science vocabulary knowledge; and the relationship between science vocabulary, language skills, and science achievement in school-age children with language/literacy disorders (LLDs) and typical language development (TD). Method: Thirty-nine sixth graders (11 with LLDs) completed standardized…

There is good evidence that high-quality instruction targeting reading-related skills in the classroom leads to gains in reading. However, considerably less is known about the possible efficacy of "remote" instruction. This study evaluated the efficacy of an interactive evidence-based language-rich literacy programme. 184 children were…

The middle and high school years represent a unique challenge for students who have not yet attained proficiency with word reading. By this time, it is generally expected that students will be able to independently read a variety of texts to gain content knowledge and to read for understanding. Students with or at-risk for learning disabilities…

Motivated by the proliferation of artificial intelligence that has the potential to promote self-access learning, this study utilizes a sequential explanatory quasi-experimental mixed methods design to investigate the efficacy of Google Assistant (GA) in facilitating second language (L2) vocabulary learning compared to online dictionaries. A…

This study evaluated the feasibility of the Knowledge, Language, and Inquiry (K.L.I.) intervention, designed to support Grades 3-5 multilingual students classified as English learners (ML-ELs) in building content knowledge, language skills, and reading comprehension through inquiry-based small-group instruction. Feasibility was examined across…

In this study, we examine preschool storybook apps to identify the types of characters represented in these stories and how they relate to design quality and opportunities for children to build their vocabularies -- a significant predictor of later success in learning to read. Specifically, we sought to understand (a) how storybook apps portray…

Purpose: Converging evidence demonstrates that robust academic vocabulary and morphology instruction improves literacy outcomes of multilingual adolescents. However, few interventions have focused on teaching word analysis using bound Latin roots, the major meaning-carrying constituents of academic words (e.g. voc meaning "speak" in…

Research Findings: This study investigated the effectiveness of a home-based intervention in increasing the intrinsic reading motivation and Chinese oral vocabulary of minority South Asian children in Hong Kong. A quasi-experiment was conducted with 78 children (M[subscript age] = 51.54 months; control: 37 children, intervention: 41 children) and…

Purpose: Parent engagement is a critical component of optimizing services for young children with disabilities, including those with language disorders. Without training, however, many parents may lack the knowledge and skills to effectively facilitate their children's language development during the essential early childhood years. The Parents…

We investigated whether learning and retaining vocabulary in a second language (L2) can be improved by leveraging a combination of memory enhancement techniques. Specifically, we tested whether combining retrieval practice, spacing, and related manipulations in a 'multidomain' pedagogical approach enhances vocabulary acquisition as compared to a…

Given their easy accessibility and dual-channel model of content presentation, instructional videos have become a favoured tool for EFL vocabulary learning tool among many students. Teachers often use various nonverbal behaviours to elicit social reactions and guide learners' attention in instructional videos. The current study conducted three…

More research attention and implementation support are needed for mathematics intervention as student achievement in this area continues to fall below desirable levels. Incremental rehearsal is an intervention to help students build reading, vocabulary, and math fluency. Research supports the use of incremental rehearsal for improving math fact…
