  • Prosody Modeling for Speech Recognition and Understanding

    This paper summarizes statistical modeling approaches for the use of prosody (the rhythm and melody of speech) in automatic recognition and understanding of speech. We outline effective prosodic feature extraction, model architectures, and techniques to combine prosodic with lexical (word-based) information.

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

    We are working with foundation officials and reformers across the country to study high school change and what it takes to improve teaching and learning. We are examining the extent to which foundation-supported schools adopt elements of effective schooling and show better, more equitable outcomes for students.

  • Towards a Quantitative Platform Independent Analysis of Knowledge Systems

    The Halo Pilot collaboratively developed a taxonomy of failures with the goal of creating a common framework of metrics against which we could measure inter- and intra- system failure characteristics of each of the three Halo knowledge applications.

  • 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.

  • 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.

  • 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…

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

  • 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.

  • 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.

  • 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 .
