This longitudinal study (data collected from 2019 to 2023) examines the relation between Spanish-English bilingual Latino toddlers' (n=46; F=22; M=24) early gesture production (Mage=18.67 months; SD[subscript age]=1.02) and later language skills (M[subscript age]=36.87 months; SD[subscript age]=0.81). Video recordings at child-age 18-months…

This paper explores use of a set of diagrammatic tools for representation and analysis of the moves a teacher makes implementing a mathematical modelling task. The focus here is on identifying what the teacher did so we can subsequently interrogate this, as to the why. Data include pre and post lesson teacher interviews and transcripts of a video…

This large-scale and longitudinal study examines early home support for learning, formal/informal home mathematics activities, and their associations with children's mathematical development between age two and six. Data were collected in Germany between 2012 and 2018, N = 1184 (49% girls, 51% boys), and 15% of children had parents with a…

We compared maternal speech in interactions of mothers with their firstborn dizygotic twin and singleton infants. Nine twins and nine singletons were video-recorded at home in spontaneous face-to-face interactions with their mothers, from the 2nd to the 6th month. Continuous micro-analysis revealed that there are more quantitative and qualitative…

This article adopts learning-behavior tracking as a research methodology within conversation analysis for second language acquisition to investigate its applicability to track and document how learning opportunities through collaborative repair work are brought about and whether they lead to second language (L2) word learning. To this end, the…

Infant-directed speech (IDS) is characterized by a range of register-typical characteristics. Many of those can be objectively measured, such as acoustic-prosodic and structural-linguistic modifications. Perceived vocal affect, however, is a socio-emotional IDS characteristic and is subjectively assessed. Vocal affect goes beyond acoustic-prosodic…

Background: The forest school and nature kindergarten approach to early childhood education and care (ECEC) has been established for well over 50 years in the United Kingdom and across parts of Europe including Scandinavia. One example where the nature kindergarten approach has recently taken a foothold is the Australian 'bush kinder'. Bush…

This longitudinal study aimed to investigate infants' spontaneous object interactions during naturalistic longitudinal observations in a day care centre in Japan. Infants' and caregivers' interactions during free play time were videotaped. The main focus related to how infants' object interactions changed during locomotor development. Observations…

This ethnographic, qualitative case study empirically explores how six youth from refugee backgrounds positioned their identities through design choices in producing reaction videos--a popular YouTube genre--at school in their settlement context. Through reflexive thematic analysis, we identified three ways in which youth took ownership of how…

In this paper we use novel data to test the direct and indirect paths between teacher self-efficacy and student outcomes. This includes how teacher self-efficacy is linked to student, teacher, and expert rater views of lesson quality. Our results illustrate how the link between teacher self-efficacy and instructional quality is sensitive to how…

Purpose: The purpose of this study was to examine the measurement structure of the linguistic features of speech-language pathologists' (SLPs) talk during business-as-usual therapy sessions in the public schools, and to test the longitudinal stability of a theorized dimensional structure consisting of quantity, grammatical complexity, and lexical…

School psychology is experiencing a shortages crisis. Within this two-part study, the Social Cognitive Career Theory was used to examine the impact of video interventions on students' choice and application to school psychology programs. A sub-sample of participants were followed across 4 years. Findings suggest that, when measured immediately…

Mind-mindedness (MM) refers to caregivers' proclivity to treat a child as having an active and autonomous mental life. It has been shown to be a powerful predictor of many developmental outcomes and to mitigate the impact of risk conditions. However, longitudinal studies on MM reporting changes over time and individual differences among mothers…

Fast-growing and evolving online content has enabled responsive curriculum updates to support students' learning of how to apply concepts to understand and solve real world problems. Written case studies have long served this purpose in a wide variety of disciplines, and many educators have seen value in presenting cases through the use of online…

Pointing has long been considered influential in language acquisition. Certain pre-linguistic vocal expressions may hold even greater value in addressing the transition to language. The goal of the present study is longitudinal evaluation of early communicative development, addressing the influence of pre-linguistic gestures and vocal expressions.…
