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
As an increasing number of robots have been designed to interact with people on a regular basis, research into human-robot interaction has become more widespread. At the same time, little work has been done on the problem of longterm human-robot interaction, in which a human uses a robot for a period of weeks or months. As people spend more time with a robot, it is expected that how they make sense of the robot - their “cognitive model” of it - may change over time. In order to identify factors that will be critical to the future development of a quantitative cognitive model of long-term human
To help answer questions about the behavior of participants in human-robot systems, we propose the Cognitive Evaluation of Human-Robot Systems (CEHRS) method based on our work with the Personal Exploration Rover (PER). The CEHRS method consists of six steps: (1) identify all system participants, (2) collect data from all participant groups, including the system’s creators, (3) analyze participant data in light of system-wide goals, (4) answer targeted questions about each participant group to determine the flow of knowledge, information, and influence throughout the system, (5) look for
The authors present an exploratory study of Black middle school boys who play digital games. The study was conducted through observations and interviews with Black American middle school boys about digital games as an informal learning experience. The first goal of the study is to understand the cultural context that Black students from economically disadvantaged inner-city neighborhoods bring to playing digital games. The second goal of the study is to examine how this cultural context affects the learning opportunities with games. Third, the authors examine how differences in game play are

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
John Falk and Lynn Dierking tackle the challenge of helping museums become better at the learning process for visitors. As they put it, "[d]igital media, well designed and wisely used, are important tools that can enhance visitor interaction and learning in museums, ensuring that these environments inspire and provoke curiosity and further understanding among visitors with varying backgrounds, interests, and knowledge levels."
This article is a response to Harris Shettel's commentary which appeared in Curator (48/2, April 2005) on two of four articles which appeared in Curator (47/2), the subject of which was interactives in museums.
Goodman Research Group, Inc. (GRG) conducted front-end evaluation and Alpha testing for the Harvard-Smithsonian Center for Astrophysics of EarthScope Panorama, an interactive Earth science game for middle school youth. The front-end evaluation focused on the prospective content, format, and platform of the game, with the broad goal of assessing four different game prototypes in a population of middle school students. The specific objectives of the evaluation were to document and assess what students already know about EarthScope-related themes and content, what geoscience questions they have

There is a recognized need to rigorously examine the efficacy of approaches to supporting informal learning. In this study, we used a 2 × 2 factorial experimental design to test the impact of a computer guide on 3 proximal measures of visitor learning at an interactive math exhibit. In total, 128 families were systematically assigned to engage with the exhibit either with or without access to a supplementary computer kiosk. Visitor groups with access to the computer spent longer, on average, at the exhibit and engaged in more mathematical behaviors compared to other groups. However, based on

Do video games have positive impacts on the academic K–12 curriculum? The authors of this paper conducted a literature review of more than 300 research articles on the use of video games in the classroom. Their analysis found minimal evidence that video games have positive effects on mathematics and science learning.
