Grounding is not shared understanding : distinguishing grounding at an utterance and knowledge leve
This paper argues that for the study and facilitation of collaborative learning, existing theories of grounding such as that of Clark and Shaefer  cannot be applied without adjustments. When comparing collaborative learning and conversation, four dimensions can be identified where grounding at a knowledge level differs from the grounding at an utterance level. Firstly, the indirect access and the existence of a range of manifest meanings, poses the need for a notion of groundedness'. Second
Collaborative Ontological Engineering of Instructional Design Knowledge for an ITS Authoring Environ
Intelligence in an ITS authoring system could rely on content-based engineering of instructional design (ID) knowledge, i.e. based on principles such as conceptualization, standardization and theory -awareness. An ontology - based architecture with appropriate ontologies has been proposed for a theoryaware ITS authoring system. Ontological engineering (OE) as a collaborative process jointly conducted by an OE expert and an ID expert is presented as a step on a roadmap towards a theory-aware ITS
Size and Scale
Another good lesson plan from DiscoverySchool.com, the Size and Scale Web site gives teachers a well conceived and thorough activity on the physics of size and scale. Objectives of the lesson include: understanding the relative sizes of bodies in our solar system and the problem of making a scale model of the entire solar system (because the distances in space are so great that even a very small scale model would be too large to be practical). The site contains all the information needed to comp

Basics of Fluid Mechanics
This book describes the fundamentals fluid mechanics phenomena for engineers and others. This book is designed to replace all introductory textbook(s) or instructor's notes for the fluid mechanics in undergraduate classes for engineering/science students but also for technical peoples. It is hoped that the book could be used as a reference book for people who have at least some basics knowledge of science areas such as calculus, physics, etc.
Architecture and Interior Design for 20th Century America: Samuel Gottscho and William Schleisner
The Gottscho-Schleisner Collection is comprised of over 29,000 images primarily of architectural subjects, including interiors and exteriors of homes, stores, offices, factories, historic buildings, and other structures. Subjects are concentrated chiefly in the northeastern United States, especially the New York City area, and Florida. Included are the homes of notable Americans, such as Raymond Loewy, and of several U.S. presidents, as well as color images of the 1939-40 New York World's Fair.

How To Make A Digi-Brick
This project examines a non-traditional method of construction generated through a digital design process that leverages digital fabrication techniques related to masonry construction. Where as architects? use of computers first affected shape and structure, it is now additionally affecting material, construction, and craft. This design proposal explores these concepts through the production of a wall using simple configuration and reconfiguration of a repeated module adaptable to differing and
Case study of a professional development program: meaningful technology integration in secondary edu
This case study investigated the effects of the design, development, implementation, and evaluation of a professional development program to facilitate the meaningful integration of technology into the curriculum for secondary teachers at a large suburban school. This study addressed the problem of the high cost of technology for a district that had yielded disappointing levels of meaningful technology integration in the teaching and learning process. The professional development program was bas

Exploring Semantic Description and

Automatic Composition of
In the implementation of e-learning frameworks, a problem still unsolved is how to use and integrate low-level learning services to compose more complex high-level services or tools that make sense to both tutors and learners. In that sense semantic description of Grid learning Services appears like a powerful tool to be used for discovering and matching learning services depending of a set of parameters inside the learning framework. These parameters must represent significant functional charac

Towards educational data mining: Using data mining methods for automated chat analysis to understand
In this paper we investigate the application of data mining methods to provide learners with real-time adaptive feedback on the nature and patterns of their on-line communication while learning collaboratively.We derived two models for classifying chat messages using data mining techniques and tested these on an actual data set . The reliability of the classification of chat messages is established by comparing the models performance to that of humans. Results indicate that the classificatio

Developed by online museum educators, Pieces of Science is described as "an online gallery of sixteen educational resources related to a collection of historical science objects." The sixteen subjects are organized by grade level and include such topics as lighting rods, Apollo 8, a lunar module, Priestleyï¿½s physics project, and penicillin. Each page contains a variety of resources, but the lighting rod page, for example, explains the history of how Benjamin Franklin used lighting rods to s
