  • Project Halo: Towards a Digital Aristotle

    Project Halo is a multi-staged effort, sponsored by Vulcan Inc, aimed at creating the Digital Aristotle, an application that will encompass much of the world’s scientific knowledge and be capable of applying sophisticated problem solving to answer novel questions.

  • Collaborative Modeling: Hiding UML And Promoting Data Examples In NEMo

    We describe a Web-based tool for modeling that creates and manipulates a simple data model without representing it in UML, while promoting collaboration and the use of examples to compare and validate the model.

  • Teacher Assignments And Student Work As Measures Of Opportunity To Learn

  • The Networked Classroom

    On the basis of more than a decade of successful reports from the field and increasing evidence supporting wide-scale adoption, researchers have begun to connect teachers’ insights about the technology to education theory and are documenting the technology’s effectiveness in enhancing student participation and achievement in mathematics.

  • A National Look at Children and Families Entering Early Intervention

    The National Early Intervention Longitudinal Study (NEILS) is the first study of Part C of the Individuals With Disabilities Education Act (IDEA) early intervention system with a nationally representative sample of infants and toddlers with disabilities. This article presents national estimates of characteristics of infants and toddlers and their families at the time they entered…

  • Six Years Of Knowledge Networking In Learning Sciences And Technologies

    For learning and education to take full advantage of new and evolving information technologies and to contribute to the evolution of those same technologies, there is a fundamental need to explore research issues and potential synergies in cross-disciplinary studies of learning and technology.

  • Technology’s Contribution To Teaching And Policy: Efficiency, Standardization, Or Transformation?

    We begin this chapter with a brief sketch of alternative perspectives on the ways in which technology can support education policy and practice. We will suggest that the connection between technology and policy is looser than that between policy and the other mechanisms described in this volume .

  • Designing Handheld Software To Support Classroom Assessment

    Since 2002, Project WHIRL (Wireless Handhelds In Reflection on Learning) has investigated potential uses of handheld computers in K-12 science classrooms using a teacher involved process of software development and field trials.

  • Technical Appendix: Exploring Assignments, Student Work, And Teacher Feedback In Reforming Schools: 2002-03 Data From Washington State

    Eight assignments, four typical and four challenging, were collected from teachers over the course of the school year. Student work associated with the teacher assignments was also collected three times during the year from a random sample of students predetermined by the researchers and blind to the teachers.

  • Closing The Digital Divide: Evaluation Of The World Links Program

    The World Bank and, subsequently, the World Links organization provided schools in developing countries with networked computers and training that supports integration of ICT into teaching. The study examines the services provided, documents their impact, and draws implications for policy in developing countries.

  • Speaker Recognition using Prosodic and Lexical Features

    We investigate the contribution of modeling prosodic and lexical patterns, on performance in the NIST 2003 Speaker Recognition Evaluation extended data task.

  • The Relationship Between Dialogue Acts and Hot Spots in Meetings

    We examine the relationship between hot spots and dialogue acts in roughly 32 hours of speech data from naturally-occurring meetings. Results reveal that four independently-motivated involvement categories (non-involved, disagreeing, amused, and other) show statistically significant associations with particular DAs.
