Primary school students rely heavily on textbooks for instruction. Using the variety of textbooks, a description of the theme textbooks' linguistic quality is conspicuously absent, particularly for students in the fifth grade. Language fit for students' growth, communicative language, and coherence and cohesiveness were all included in this…

Emotion words allow us to identify, describe and regulate our emotional states. Emotion vocabulary grows through childhood, but little research has considered emotion words in the context of children's written language. To address this gap, we used a cross-corpus developmental approach to chart the emergence of emotion words in children's reading…

Shared intentionality theory posits that at age 3, children expand their conception of plural agency to include 3- or more-person groups. We sought to determine whether this conceptual shift is detectable in children's pronoun use. We report the results of a series of Bayesian hierarchical generative models fitted to 479 English-speaking…

Research indicates that the early years are a pivotal time for developing foundational mathematical knowledge, and that early experiences with mathematics have a lasting impact on later numeracy skills and academic achievement. However, the importance of early mathematical thinking and learning is often undervalued or overlooked in early childhood…

Abstract Accepted 12 November 2024 In this essay I reflect on James P. Lantolf's contributions to cultural-historical theory and second language learning. I begin with my personal subjectivity and experiences as a limited learner of additional languages beyond English. This anecdotal opening introduces the tension between formal learning in school…

The current study examined how mothers' production of four types of internal state words at multiple ages across the second year in a free play context was related to their infants' acquisition of those words. Twenty-nine mother-infant dyads were videotaped for 18 minutes during free play when infants were 13 and 17 months old. Mothers' total and…

This study examines identity construction and conflict in the case of a woman whose parents replaced the local language with the official language at the home in the city of Tabriz in northwestern Iran, where the local language, Azerbaijani, is overshadowed by Persian as the official language of the state. In such contexts, Shifting away from the…

The paper investigates a Hungarian-English bilingual child's Sarah's second language acquisition (SLA) with a special focus on how she integrated English (L2) into her speech to convey the intended meaning and negotiate the multiple identities she developed in her bilingualism in various social contexts. An ethnographic single-case study research…

In formal education, the teaching of natural sciences begins when children are about 12 years old. Teachers justify this with the difficulty and abstraction of concepts in these sciences, and they refer to the theory of child development by Piaget. However, numerous examples from everyday life, from non-formal education, analysis of the…

This paper provides an overview of the features of caregiver input that facilitate language learning across early childhood. We discuss three dimensions of input quality: interactive, linguistic, and conceptual. All three types of input features have been shown to predict children's language learning, though perhaps through somewhat different…

The Mandarin resultative verb compound (RVC; e.g., "tui dao" "push fall" and "pa shang" "climb ascend") encodes complex events composed of an initiating action and resulting activity or state. This study investigated when Mandarin-speaking children acquired this language-specific device. Specifically, we…

The purpose of this study was to explore the use of code-switching in the narratives of dual-language Latino preschoolers, specifically by examining its incidence, types, functions, and grammaticality. Previous work has investigated code-switching in younger children and in older children and adults, but relatively little work has investigated…

This longitudinal study examined the development of narrative micro- and macrostructure in Japanese-English bilingual returnee children. Returnees are children of immigrant families who move to a foreign country, spending a significant portion of their formative developmental years in the foreign majority language context before returning to their…

Conceptualizing numbers as discursive constructs generated in, and for the sake of, communication, we investigated the development of the numerical discourse of Milo, a boy who was 2 years and 8 months old when we first met him and whom we then followed for 18 months. Our analyses of the child's evolving responses to the question "Where is…

We are expected to behave appropriately to suit social situations. One form of behavioral control is the selection of a linguistic register that is appropriate to the listener. Register selection errors can sometimes be interpreted as rude behavior and result in having a bad influence on the relationship with the listener and the evaluation by…
