  • Performance Assessment Links In Science (PALS)

    SRI International is developing Performance Assessment Links in Science (PALS), an on-line, standards-based, interactive resource bank of science performance assessments.

  • Finding Consensus Among Words: Lattice-based Word Error Minimization

    We describe a new algorithm for finding the hypothesis in a recognition lattice that is expected to minimize the word error rate (WER). Our approach thus overcomes the mismatch between the word-based performance metric and the standard MAP scoring paradigm that is sentence-based, and that can lead to sub-optimal recognition results.

  • Combining Words and Prosody for Information Extraction from Speech

    In this work we demonstrate the use of em prosodic cues, alone and in combination with words, for segmentation and name finding. In experiments, we find that prosodic cues alone allow sentence and topic segmentation that is at least as good as word-based methods alone, and that combining both types of cues gives significant wins.

  • Task-based Information Management

    We are constructing a system, called the Task-based Information Distribution Environment (TIDE), that delivers information to participants in a dynamic collaboration by evaluating the relevance of incoming and newly generated information to collaborators’ current tasks.

  • Construct Validation Of Mathematics Achievement: Evidence From Interview Procedures

    This study investigated the validity of measures derived from a large-scale multiple-choice achievement test in mathematics, using evidence from introspective think-aloud protocols of students as they attempted test items.

  • Prolegomena to a Theory of Disability, Inability and Handicap

    In this paper we extend a theory of action, IPT to try to elucidate these concepts. This attempt at elucidation is itself at most a prolegomena to a study that can usefully feedback into the moral and legal issues involving disabilities.

  • Globe Year 4 Evaluation: Evolving Implementation Practices

    GLOBE students are involved in authentic science investigations, led by GLOBE scientists who have designed the data collection protocols and review and analyze the student data.

  • Science In The Palm Of Their Hands

    If we’re serious about having children use technology in K–12 classrooms, then we need to convince the gatekeepers of those classrooms as to the worth of the technology. Doing so requires that we speak in the language of the teachers’ profession: first identify the learning experiences and their outcomes, along with why those are desired,…

  • Toward A Learning Technologies Knowledge Network

    This paper describes the rationale and operations of the NSF-funded Center, and first-year progress in defining a set of CILT partnership projects with many other institutions that came out of our national theme-team workshops.

  • From Moo To Meow: Domesticating Technology For Online Communities

    Informed by our experience with TAPPED IN and reviews of related work, we are developing a new online “community-ware” technology called MEOW (Multi-user Educational Online Workspace) which can scale to handle large virtual communities.

  • Developing Educational Software Components

    Educational applications must be very flexible because curricula and teaching styles vary tremendously among institutions, locations, and even among instructors at the same institution.
