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
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
This article explores the development of observation in scientific and everyday contexts. Fundamental to all scientific activity, expert observation is a complex practice that requires the coordination of disciplinary knowledge, theory, and habits of attention. On the surface, observation appears to be a simple skill. Consequently, children may be directed to observe, compare, and describe phenomena without adequate disciplinary context or support, and so fail to gain deeper scientific understanding. Drawing upon a review of science education, developmental psychology, and the science studies
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.

Describes the use of the "Plant Wheel" by the University of California Botanical Garden as a means of providing elementary school children with a structured activity as they explore the Garden at their own pace. This activity accommodates the children's curiosity, energy, and attention span.
The Westside Science Club (WSSC) is an out-of-school time opportunity that brings participant-directed STEM activities to under-resourced late-elementary and middle school students in low-income housing units in Los Angeles. WSSC and CCI Solar began a collaboration in 2012 with funding from the NSF to connect research scientists from Caltech with the underserved youth in the club. Another community partner, Wildwood School, provided high school students to act as near-peer mentors for the club members. CCI Solar's research on the efficient and economical conversion of solar energy into stored chemical fuel provides an entry point for informal science education activities designed to introduce pre-high school participants to basic chemistry and related STEM concepts such as physics and plant biology. Activities were largely student driven, though lessons were developed by the team of facilitators including the club's founder Ben Dickow, Wildwood teacher Levi Simons, and students, post-docs, and staff from Caltech. Each lesson was tied to CCI Solar's research through a mind-map of related chemistry concepts. The activities were mostly intended to be "maker-type" experiences that allowed the club members to follow their own interests and questions. Caltech students and postdocs from CCI Solar helped deliver activities while honing their science communication skills with the young WSSC audience. The team is currently adapting the model of this successful collaboration to develop another science club in a different Los Angeles community. Two-years of lessons developed from this project, an evaluation of the project by Kimberly Burtnyk of Science for Society, and a model on how to replicate such a program are available in the project final report below. This was a two-year pilot program that was completed in July 2014.
In recent years academic, engineering, business, and other fields, have launched major research and development efforts into the study and application of nanoscale science, engineering, and technology. In spite of all these efforts and the investment of millions of dollars, the general public has had little access to research findings and knowledge about the application of nanoscience and technology. Several studies have been conducted to assess public knowledge and understanding; they show that a large percentage of the public is not aware of this emerging field (as compared with other fields
