On-going design of Mathematics Education Markup Language (MeML) is presented. MeML is an XML-based language and the key component of Web-based Mathematics Education framework (WME) under investigation. MeML enables authoring of systematic and interoperable mathematics education pages that may contain active parts for various mathematics and educational purposes such as example generation, answe...

In this paper, the authors first discuss the main rationales of situated cognition and its connections with innovation in teacher education. The challenges that might occur in applying situated cognition in teacher education programs, including insufficient opportunities for cognition apprenticeship, limited social interactions, and constraints in microteaching, are then presented. Correspondin...

An efficient moving object extraction algorithm suitable for real-time content-based multimedia streaming systems is proposed in this paper. A Motion Vector (MV) based object extraction is used to dynamically detect the objects. To utilize the bandwidth efficiently, the important object can be real time detected, encoded, and transmitted with higher quality and higher frame rate than those of b...

BACKGROUND All accredited US residency programs are expected to offer curricula and evaluate their residents in 6 general competencies. Medical schools are now adopting similar competency frameworks. We investigated whether a Web-based program could effectively teach and assess elements of systems-based practice. METHODS We enrolled 276 medical students and 417 residents in the fields of surg...

This paper describes a concept-based course maintenance system that we have developed for Carnegie Technology Education. The system can check the consistency and quality of a course at any moment of its life and also assist course developers in some routine operations. The core of this system is a refined approach to indexing the course material and a set of “scripts” for performing different o...
