Socio-cognitive functions of space in collaborative settings : a literature review about Space, Cogn
This document reports on a brief literature review about social and cognitive functions of spatial features used when collaborating in both physical and virtual settings. Those concepts come from various fields like social, cognitive as well as environmental psychology or CSCW (Computer Supported Collaborative Work). I briefly summarize the social and cognitive affordances of spatial features like distance, proxemics, co-presence, visibility or activity in the context of physical and virtual spa
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
Design of adaptive feedback in a web educational system
This paper presents our interdisciplinary approach for the design of a technology-based learning environment for orthopaedic surgery. We present how we designed a part of this environment. This part is in relation to the web environment. The key idea is to produce an intelligent feedback in relation to the learner's activity. The didactical analysis of teaching and learning in the workplace gives a framework to build the computational representation of knowledge. This analysis is shown within th
This book, designed for a two-semester general physics course for science and engineering students, presents a logical and unified approach emphasizing the conservation laws, the concepts of fields and waves, and the atomic view of matter. The special theory of relativity, in its more basic aspects, is used throughout the text as one of the guiding principles that must be met by any physical theory
Ask an Astronomer for Kids
This site provides answers and photos for 200 common questions about astronomy and objects in space. Topics include planets, stars, the solar system, comets, asteroids, galaxies, and the night sky.
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
Middle School Portal: Math and Science Pathways (MSP2)
A Dictionary of Units of Measurement was written by Russ Rowlett, the Director of the Center for Mathematics and Science Education at the University of North Carolina at Chapel Hill. This Web site provides information on everything from the Metric System to Viscosity Grades and many other measurement units in between. A simple but very useful site, visitors can find answers to their basic unit measurement questions or just have fun learning about some of the common and somewhat obscure ways we m
Middle School Portal: Math and Science Pathways (MSP2)
This resource discusses how scientists and engineers study biological systems to develop artificial systems, in this case artificial olfaction. The sense of smell is extremely complex, and scientists working on artificial olfaction have had to study this biological system extensively to extract some basic principles upon which to build their devices. Disciplines of emphasis will involve biology, chemistry, electronics, and teamwork. Copyright 2005 International Technology Education Association
Growing Power Farm: Aquaponics
Aquaculture is the symbiotic cultivation of plants and aquatic animals in a re-circulating system. Growing Power uses Tilapia and Yellow Perch to fertilize a variety of crops and herbs using aquaponics. Currently, we have three Tilapia systems and six Yellow Perch aquaponics systems in our greenhouses at our urban farm in Milwaukee.

computer simulation of the demolition of a structure
This is created by VFIFE (V-5), a new finite element technique capable of calculation motion and stresses of a structural system. It is developed by Center for Bridge Engineering Research, National Central University, Taiwan.
Perceived Versus Actual Risk for Hypertension and Diabetes in the African American Community
Hypertension and diabetes mellitus are leading health concerns in the United States. Despite a disproportionate burden of both conditions among African Americans, it is estimated that 44% of diabetes cases and one quarter of hypertension cases within this population are undiagnosed. Lack of awareness of the risk of these conditions may hinder preventive efforts and the adoption of positive lifestyle changes. Based on the findings from a pilot study to develop and standardize uniform screening fo
Experiences of Racism Among African American Parents and the Mental Health of Their Preschool-Aged C
Objectives. We examined the relationship between parents’ experiences of racism and children’s well-being and the influence of the residential neighborhood characteristics on this relationship. Methods. African American families were recruited from Baltimore neighborhoods. Parental measures included racism experiences and coping. Neighborhood measures included demographic characteristics, social cohesion, and social climate. Children’s mental health was assessed with the Child Behavior Ch

A lecture by Kevin Rudd, Prime Minister of Australia
The Australian Prime Minister, Mr Rudd, was elected to office in November last year and moved quickly to ratify the Kyoto Protocol and deliver a national apology to the Stolen Generations of Indigenous Australians. He has identified fighting inflation, acting decisively on climate change, improving the health and hospital system, investing in education and putting fairness back into Australian workplaces as his Government's key priorities. Mr Rudd has said that his Government's mandate is to bui
Scaling Galileo's Solar System - Locating the Globes
In this activity students plot the position of model planets on a campus map by converting from polar coordinates to Cartesian coordinates, after calculating the planet positions from scaled orbits and periods. They recreate spreadsheets, shown in a Powerpoint module, with formulas that answer various pieces of the overall question. This module is the fourth in a series of four on the Galilean Solar System, and was designed for an undergraduate class where students look at geological questions m
