“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

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

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

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

Parents’ beliefs about their influence on children’s scientific and religious views: Perspectives from Iran, China and the United States

Parents in Iran, China and the United States were asked 1) about their potential influence on their children's religious and scientific views and 2) to consider a situation in which their children expressed dissent. The Iranian and US parents endorsed their influence on children's beliefs in both domains. By contrast, Chinese parents claimed more influence in the domain of science than religion. Most parents spoke of influencing their children via Parent-only mechanisms in each domain (e.g., discussion, teaching), although US parents did spontaneously note Multiple sources for the transmission of religious views (e.g., church, other influential adults). Parents proposed a similar stance towards children’s dissenting religious and scientific views. Chinese and US parents were more likely to express Supportive approaches and Iranian parents were more likely to express a Directive approach by comparison. The present research informs our understanding of the cultural transmission of views about science and religion

Children’s ideas about what can really happen: The impact of age and religious background

Five to 11-year-old U.S. children, from either a religious or secular background, judged whether story events could really happen. There were four different types of stories: magical stories violating ordinary causal regularities; religious stories also violating ordinary causal regularities but via a Divine agent; unusual stories not violating ordinary causal regularities but with an improbable event; and realistic stories not violating ordinary causal regularities and with no improbable event. Overall, children were less likely to judge that religious and magical stories could really happen than unusual and realistic stories although religious children were more likely than secular children to judge that religious stories could really happen. Irrespective of background, children frequently invoked causal regularities in justifying their judgments. Thus, in justifying their conclusion that a story could really happen, children often invoked a causal regularity whereas in justifying their conclusion that a story could not really happen, they often pointed to the violation of a causal regularity. Overall, the findings show that children appraise the likelihood of story events actually happening in light of their beliefs about causal regularities. A religious upbringing does not impact the frequency with which children invoke causal regularities in judging what can happen, even if it does impact the type of causal factors that children endorse

The Theoretical and Methodological Opportunities Afforded by Guided Play With Young Children

For infants and young children, learning takes place all the time and everywhere. How children learn best both in and out of school has been a long-standing topic of debate in education, cognitive development, and cognitive science. Recently, guided play has been proposed as an integrative approach for thinking about learning as a child-led, adult-assisted playful activity. The interactive and dynamic nature of guided play presents theoretical and methodological challenges and opportunities. Drawing upon research from multiple disciplines, we discuss the integration of cutting-edge computational modeling and data science tools to address some of these challenges, and highlight avenues toward an empirically grounded, computationally precise and ecologically valid framework of guided play in early education
