Comparing Automatic and Manual Measures of Parent–Infant Conversational Turns: A Word of Caution

The Language ENvironment Analysis system (LENA) records children’s language environment and provides an automatic estimate of adult–child conversational turn count (CTC). The present study compares LENA’s CTC estimate to manually coded CTC on a sample of 70 English-speaking infants recorded longitudinally at 6, 10, 14, 18, and 24 months of age. At each age, LENA’s CTC was significantly higher than manually coded CTC (all ps < .001, Cohen’s ds: 0.9–2.05), with the largest discrepancies between the two methods observed at younger ages. The Limits of Agreement Analyses confirm wide disagreements between the two methods, highlighting potential problems with automatic measurement of parent–infant verbal interaction. These findings suggest that future studies should validate LENA’s CTC estimates with manual coding.     

Early Second Language Learning through SparkLing™: Scaling up a Language Intervention in Infant Education Centers

Infancy (0–3 years) represents a unique time for language learning. Previous research shows that infants' second language (L2) learning advances rapidly in early education centers, through a research‐based method and curriculum delivered by native‐speaking language tutors. Here we test the potential of this method for broad application, through an interactive online tool, SparkLing?, which trains and certifies language tutors to implement the program in infant education centers. Intervention infants (n = 168) from families of predominantly low socioeconomic status (SES) backgrounds in Madrid, Spain, experienced 18 or 36 weeks of L2 (English) exposure, through daily, 45‐min, group sessions led by SparkLing?‐trained tutors and were compared to a matched Current Practice Comparison (CPC) group of peers (n = 72). Intervention children outperformed the CPC group and showed rapid gains in English comprehension and production. SES was not a significant factor in learning. Infants' L2 skills advance quickly using this research‐to‐practice, scalable program for play‐based infant L2 instruction.     

Speech perception in infancy predicts language development in the second year of life: a longitudinal study

Infants' early phonetic perception is hypothesized to play an important role in language development. Previous studies have not assessed this potential link in the first 2 years of life. In this study, speech discrimination was measured in 6-month-old infants using a conditioned head-turn task. At 13, 16, and 24 months of age, language development was assessed in these same children using the MacArthur Communicative Development Inventory. Results demonstrated significant correlations between speech perception at 6 months of age and later language (word understanding, word production, phrase understanding). The finding that speech perception performance at 6 months predicts language at 2 years supports the idea that phonetic perception may play an important role in language acquisition.     

Lessons Learned from a Predominantly Latinx Autistic Population: Preliminary Effects of the PEERS Intervention on Neural and Perceived Educational Performance

Thirteen autistic teens, who were predominantly Latinx, completed the Program for the Education and Enrichment of Relational Skills (PEERS), a 16-week social skills intervention. Time-frequency decomposition was calculated using advanced electroencephalographic techniques to measure oscillatory brain activity during reward anticipation and processing before and after PEERS. Fourteen neurotypical teens participated but did not receive intervention. The perception of educational performance was also measured. The perception of educational performance did not differ between groups and did not change after participation in PEERS. Approach motivation increased after intervention in the autistic group. This suggests an enhancement of social motivation after learning social skills in a group composed of a majority of Latinx autistic teens.     

Measurement Models,Estimation, and the Study of Change

The study of change is based on the idea that the score or index at each measurement occasion has the same meaning and metric across time. In tests or scales with multiple items, such as those common in the social sciences, there are multiple ways to create such scores. Some options include using raw or sum scores (i.e., sum of item responses or linear transformation thereof), using Rasch-scaled scores provided by the test developers, fitting item response models to the observed item responses and estimating ability or aptitude, and jointly estimating the item response and growth models. We illustrate that this choice can have an impact on the substantive conclusions drawn from the change analysis using longitudinal data from the Applied Problems subtest of the Woodcock–Johnson Psycho-Educational Battery–Revised collected as part of the National Institute of Child Health and Human Development's Study of Early Child Care. Assumptions of the different measurement models, their benefits and limitations, and recommendations are discussed.     

The Impact of Early Social Interactions on Later Language Development in Spanish–English Bilingual Infants

This study tested the impact of child‐directed language input on language development in Spanish–English bilingual infants (N = 25, 11‐ and 14‐month‐olds from the Seattle metropolitan area), across languages and independently for each language, controlling for socioeconomic status. Language input was characterized by social interaction variables, defined in terms of speech style (“parentese” vs. standard speech) and social context (one‐on‐one vs. group). Correlations between parentese one‐on‐one and productive vocabulary at 24 months (n = 18) were found across languages and in each language independently. Differences are highlighted between previously published monolingual samples, which used the same methods as the current study of bilingual infants. The results also suggest cultural effects on language input and language development in bilingual and bicultural infants.     

Beliefs von Studierenden sonder- und grundschulpädagogischer Studiengänge

The implementation of inclusion in schools currently requires new reflections of competence profiles of the teachers involved. Especially in elementary school, which can so far be considered as the most developed institution of inclusive schooling in Germany, questions of differences in the profiles of elementary and special education teachers have been raised. As professional skills also have motivational and volitional aspects, a beliefs model (domain overlapping) was developed based on the construction of the TEDS-M research project, which aims to study specific special educational beliefs. Using a quantitative questionnaire designed in the context of a corresponding preliminary investigation a three-factor-solution for mapping a special supportive belief profile among student teachers and teachers in the field of elementary and special education was tested. Initially this profile model was confirmed by the results of a subsequent analysis based on a nationwide sample of elementary school and special education students (N = 951). In addition to these findings different manifestations of the beliefs model could be identified among student teachers for elementary schools and student teachers for special education.     

Mapping transgender policyscapes: a policy analysis of transgender inclusivity in the education system in Ontario*

Abstract

In this paper we draw on Mettler’s concept of the policyscape and apply it to an examination of policy-making processes and events as they pertain specifically to an analysis of transgender inclusivity and gender diversity in the Ontario context. We employ Ball’s focus on policy as text and policy ensembles alongside Bailey’s employment of policy dispositifs to map key events that characterize important legislative developments that define the Ontario education policy landscape with regards to addressing gender identity and gender expression as a basis for anti-discrimination. We situate particular events such as the GSA (Gay Straight Alliance or Gender and Sexuality Alliance) and sex education controversies within a broader context of trans activism, which we identify as pointing to quite specific contingencies that characterize the Ontario policyscape. Overall, the paper extends a consideration of the specificities of the Ontario case in Canada to a broader reflection on the utility of the policyscape as a crucial concept for making sense of the relevance of more general characteristics of a spatially-focused trans informed policy analysis.     

Early Language Learning and Literacy: Neuroscience Implications for Education

The last decade has produced an explosion in neuroscience research examining young children's early processing of language that has implications for education. Noninvasive, safe functional brain measurements have now been proven feasible for use with children starting at birth. In the arena of language, the neural signatures of learning can be documented at a remarkably early point in development, and these early measures predict performance in children's language and pre‐reading abilities in the second, third, and fifth year of life, a finding with theoretical and educational import. There is evidence that children's early mastery of language requires learning in a social context, and this finding also has important implications for education. Evidence relating socioeconomic status (SES) to brain function for language suggests that SES should be considered a proxy for the opportunity to learn and that the complexity of language input is a significant factor in developing brain areas related to language. The data indicate that the opportunity to learn from complex stimuli and events are vital early in life, and that success in school begins in infancy.
