“How will you construct a pathway system?”: Microanalysis of teacher-child scientific conversations

During the preschool years, children’s question-explanation exchanges with teachers serve as a powerful mechanism for their early STEM knowledge acquisition. Utilizing naturalistic longitudinal classroom data, we examined how such conversations in an inquiry-based preschool classroom change during an extended scientific inquiry unit. We were particularly interested in information-seeking questions (causal, e.g. “How will you construct a pathway?”; fact-based, e.g., “Where’s the marble?”). Videos (n = 18; 14 hours) were collected during a three-week inquiry unit on forces and motion and transcribed in CLAN-CHILDES software at the utterance level. Utterances were coded for delivery (question vs. statement) and content (e.g., fact-based, causal). Although teachers ask more questions than children, we found a significant increase in information-seeking questions during Weeks 2 and 3. We explored the content of information-seeking questions and found that the majority of these questions were asked by teachers, and focused on facts. However, the timing of fact-based and causal questions varied. Whereas more causal questions occurred in earlier weeks, more fact-based questions were asked towards the end of the inquiry. These findings provide insight into how children’s and teacher’s questions develop during an inquiry, informing our understanding of early science learning. Even in an inquiry-learning environment, teachers guide interactions, asking questions to support children’s learning. Children’s information-seeking questions increase during certain weeks, suggesting that providing opportunities to ask questions may allow children to be more active in constructing knowledge. Such findings are important for considering how science questions are naturally embedded in an inquiry-based learning classroom

But how does it develop? Adopting a sociocultural lens to the development of intergroup bias among children

We argue that adopting a sociocultural lens to the origins of intergroup bias is important for understanding the nature of attacking and defending behavior at a group level. We specifically propose that the potential divergence in the development of in-group affiliation and out-group derogation supports the authors’ framework but does indicate that more emphasis on early sociocultural input is required

Unique effects of book-reading at 9-months on vocabulary development at 36-months: insights from a nationally representative sample of Irish families

It is well-established that participation in shared book reading interactions with caregivers supports children’s early language and literacy development. Most of this literature focuses on reading experiences during the preschool period. Less is known about the nature and importance of such practices during infancy. Therefore, the goal of this study was to examine literacy practices between parents and infants in a large cohort study, Growing Up in Ireland. Interview, survey, and direct measurements of children’s language skills were used to examine whether parent-report of book reading practices when children were 9-months predicted child expressive vocabulary at 36-months (N=9,171). Regression analysis indicated that approximately 80% of 9- month-old Irish children are read to by parents. Characteristics of families who were more likely to report reading with children emerged: those with higher educational attainment, fewer depressive symptoms, and those who report a high-quality home language environment (e.g., reported talking more to children during everyday activities). Furthermore, children who were read to at 9-months had stronger expressive vocabulary skills at 36-months, even after accounting for socio-demographic and home literacy environment covariates measured at both 9- and 36-months. Results are discussed using a bioecological framework to describe how proximal and distal factors in the child’s environment converge to impact early childhood literacy development

What could have been done? Counterfactual alternatives to negative outcomes generated by religious and secular children

Recent research has shown that a religious upbringing renders children receptive to ordinarily impossible outcomes, but the underlying mechanism for this effect remains unclear. Exposure to religious teachings might alter children’s basic understanding of causality. Alternatively, religious exposure might only affect children’s religious cognition, not their causal judgments more generally. To test between these possibilities, 6- to 11-year-old children attending either secular (n = 49, 51% female, primarily White and middle-class) or parochial schools (n = 42, 48% female, primarily White and middle-class) heard stories in which characters experienced negative outcomes and indicated how those characters could have prevented them. Both groups of children spontaneously invoked interventions consistent with natural causal laws. Similarly, when judging the plausibility of several counterfactual interventions, participants endorsed the intervention consistent with natural laws at high levels, irrespective of schooling. However, children’s endorsement of supernatural interventions inconsistent with these laws revealed both group similarities and differences. Although both groups of children judged divine intervention (i.e., via prayer) as more plausible than mental (i.e., via wishing) and magical (i.e., via magical powers) interventions, children receiving religious (vs. secular) schooling were more likely to do so. Moreover, although children with a secular upbringing overwhelmingly chose naturalistic interventions as the most effective, children with a religious upbringing chose divine as well as naturalistic intervention. These results indicate that religious teaching does not alter children’s basic understanding of causality but rather adds divine intervention to their repertoire of possible causal factors

What would happen if?: A comparison of fathers’ and mothers’ questions to children during a science activity

Parents’ questions are an effective strategy for fostering the development of young children’s science understanding and discourse. However, this work has not yet distinguished whether the frequency of questions about scientific content differs between mothers and fathers, despite some evidence from other contexts (i.e., book reading) showing that fathers ask more questions than mothers. The current study compared fathers’ and mothers’ questions to their four- to six-year-old children (N = 49) while interacting with scientific stimuli at a museum research exhibit. Results indicated that fathers asked significantly more questions than mothers, and fathers’ questions were more strongly related to children’s scientific discourse. Results are discussed in terms of the importance of adult questions for the development of children’s scientific understanding as well as broadening research to include interlocutors other than mothers

Embedding scientific explanations into storybooks impacts children's scientific discourse and learning

Children's understanding of unobservable scientific entities largely depends on testimony from others, especially through parental explanations that highlight the mechanism underlying a scientific entity. Mechanistic explanations are particularly helpful in promoting children's conceptual understanding, yet they are relatively rare in parent-child conversations. The current study aimed to increase parent-child use of mechanistic conversation by modeling this language in a storybook about the mechanism of electrical circuits. We also examined whether an increase in mechanistic conversation was associated with science learning outcomes, measured at both the dyadic- and child-level. In the current study, parents and their 4- to 5-year-old children (N = 60) were randomly assigned to read a book containing mechanistic explanations (n = 32) or one containing non-mechanistic explanations (n = 28). After reading the book together, parent-child joint understanding of electricity's mechanism was tested by asking the dyad to assemble electrical components of a circuit toy so that a light would turn on. Finally, child science learning outcomes were examined by asking children to assemble a novel circuit toy and answer comprehension questions to gauge their understanding of electricity's mechanism. Results indicate that dyads who read storybooks containing mechanistic explanations were (1) more successful at completing the circuit (putting the pieces together to make the light turn on) and (2) used more mechanistic language than dyads assigned to the non-mechanistic condition. Children in the mechanistic condition also had better learning outcomes, but only if they engaged in more mechanistic discourse with their parent. We discuss these results using a social interactionist framework to highlight the role of input and interaction for learning. We also highlight how these results implicate everyday routines such as book reading in supporting children's scientific discourse and understanding.Published versio

Conflicting perspectives mediate the relation between parents’ and preschoolers’ self‐referent mental state talk during collaboration

We examined the relations between the referent of parents and preschoolers’ mental state talk during a collaborative puzzle‐solving task (N = 146 dyads; n = 81 3‐year‐olds, n = 65 4‐year‐olds). The results showed that parents’ references to their own knowledge and beliefs (self‐referent cognitive talk), and references to their child’s knowledge and beliefs (child‐referent cognitive talk) were both related to children’s (primarily self‐referent) cognitive talk. We then tested whether any of the observed relations could be explained by the presence of conflicting perspectives within the collaborative interaction. Mediational analyses revealed that conflicting perspectives mediated the positive relation between parents’ production of self‐referent cognitive talk and child cognitive talk. By contrast, the positive relation between parents’ production of child‐referent cognitive talk and child cognitive talk did not depend on the presence of this type of conflict. These findings highlight an important mechanism through which parents’ references to their own mind might promote children’s developing mental state talk in collaborative contexts

‘We practise every day’: Parents’ attitudes towards early science learning and education among a sample of urban families in Ireland

Educational policies increasingly emphasise early childhood science engagement. As key influencers in children’s early learning, parents (n=85) attending a science workshop in three urban schools in Ireland were surveyed regarding their attitudes towards science. Seventy per cent of parents believed that science education should begin in the pre-school years, before the age of four. Despite high levels of education, at least half of the parents expressed some lack of confidence in talking about, and in doing science with, their young children. Parents who reported less confidence in doing science activities with their children also reported reduced frequency of activities for five out of the seven science learning opportunities listed. Mothers, compared to fathers, reported less confidence in doing science activities with their children. Findings indicate that parents’ confidence in science may impact early science experiences and highlight parents as a key support for increasing early science engagement

Peer learning and cultural evolution

In this article, we integrate cultural evolutionary theory with empirical research from developmental psychology, cultural anthropology, and primatology to explore the role of peer learning in the development of complex instrumental skills and behavioral norms. We show that instrumental imitation, contingent teaching, generative collaboration, and selective copying contribute to domain-specific transmission of knowledge between peers. Stages of development and characteristics inherent to the learner and model influence how and when children learn from each other. Peer learning is persistent across societies despite cultural beliefs that favor adult–child transmission in some settings. Comparative research hints at the possibility that children's greater motivation to interact with and learn from each other may set humans apart from other primates. We conclude by outlining avenues for future research, including how individual characteristics and developmental changes in social networks, motivation, and cognition may contribute to cultural evolution.</p
