In domains with multiple competing goals, people face a basic challenge: How to make their strategy use flexible enough to deal with shifting circumstances without losing track of their overall objectives. This article examines how young children meet this challenge in one such domain, tic-tac-toe. Experiment 1 provides an overviews of development in the area; it indicates that children's tic-tac-toe strategies are rule based and that new rules are added one at a time. Experiment 2 demonstrates that even young children flexibly tailor their strategy use to meet shifting circumstances
Constraints on learning, rather than being unique to evolutionarily privileged domains, may operate in nonprivileged domains as well. Understanding of the goals that strategies must meet seems to play an especially important role in these domains in constraining the strategies even before they use them. THe presente experiments showed that children can use their conceptual understanding to accurately evaluate strategies that they not only do not yet use but hat are more conceptually advanced than the strategies they do not use. In Experiment 1, 5-year-olds who did not yet use the min strategy
Children often learn new problem-solving strategies by observing examples of other people's problem-solving. When children learn a new strategy through observation and also explain the new strategy to themselves, they generalize the strategy more widely than children who learn a new strategy but do not explain. We tested three hypothesized mechanisms through which explanations might facilitate strategy generalization: more accurate recall of the new strategy's procedures; increased selection of the new strategy over competing strategies; or more effective management of the new strategy's goal
Current accounts of the development of scientific reasoning focus on individual children's ability to coordinate the collection and evaluation of evidence with the creation of theories to explain the evidence. This observational study of parent–child interactions in a children's museum demonstrated that parents shape and support children's scientific thinking in everyday, nonobligatory activity. When children engaged an exhibit with parents, their exploration of evidence was observed to be longer, broader, and more focused on relevant comparisons than children who engaged the exhibit without
Two studies examined how parent explanation changes what children learn from everyday shared scientific thinking. In Study 1, children between ages 3- and 8-years-old explored a novel task solo or with parents. Analyses of children's performance on a subsequent posttest compared three groups: children exploring with parents who spontaneously explained to them; children exploring with parents who did not explain; and children exploring solo. Children whose parents had explained were most likely to have a conceptual as opposed to procedural understanding of the task. Study 2 examined the causal
The aim of the work reported here has been to give an overview of the support that the informal sector provides for learning and engagement with science. In addressing this goal, we have taken the view that engagement with science and the learning of science occur both within and without schools. What is of interest is not who provides the experience or where it is provided but the nature and diversity of opportunities for science learning and engagement that are offered in contemporary UK society. Thus in approaching the work we have taken a systems perspective and looked at informal
In this article, the authors review a collaborative project between two developmental psychologists and the staff of Children's Discovery Museum of San Jose. Under the broad agenda of studying the development of scientific literacy, they have been exploring the hypothesis that the guidance of parents is an important bridge between the intentions of the exhibit designer and the experience and knowledge of the child. Their research is guided by a framework inspired by a combination of socio-cultural and information-processing theories of how children learn. In the first section of this article
Young children's everyday scientific thinking often occurs in the context of parent-child interactions. In a study of naturally occurring family conversation, parents were three times more likely to explain science to boys than to girls while using interactive science exhibits in a museum. This difference in explanation occurred despite the fact that parents were equally likely to talk to their male and female children about how to use the exhibits and about the evidence generated by the exhibits. The findings suggest that parents engaged in informal science activities with their children may
Research on human–robot interaction has often ignored the human cognitive changes that might occur when humans and robots work together to solve problems. Facilitating human–robot collaboration will require understanding how the collaboration functions system-wide. The authors present detailed examples drawn from a study of children and an autonomous rover, and examine how children’s beliefs can guide the way they interact with and learn about the robot. The data suggest that better collaboration might require that robots be designed to maximize their relationship potential with specific users
Reports effects of an outdoor field trip on learning within the context of a community-based Summery Ecology Program for children between 7 and 13 years of age. Results include the finding that novel environments are poor settings for imposed task learning when compared with familiar environments.

Both metacognitive and associative models have been proposed to account for children’s strategy discovery and use. Models based on only metacognitive or only associative mechanisms cannot entirely account for the observed mix of variability and constraint revealed by recent microgenetic studies of children’s strategy change. We propose a new approach where metacognitive and associative mechanisms interact in a competitive negotiation. This approach provides the flexibility to model the observed variability and constraint.

The Seattle Aquarium seeks to discover how toddler families experience its exhibits and how to best incorporate toddler family needs in future exhibit developments. The goal of this study is to begin to document toddler-exhibit interactions in order to better understand the Aquarium experience for that audience. The specific research goal was to determine which exhibit elements are attracting and holding the attention of the toddler family audience. A total of 47 caregiver interviews and 297 toddler observations across three exhibit areas were collected from January-March 2011 at the Seattle
