Peer Conversations for e-Learning in the Grid
We take the view of 'learning as a conversational process', and argue that this can be extended to include the notions of peer-group interactions among students, tutors, and even artificial agents. This in turn lends itself to an approach to distributed conversation which builds upon modern Instant Messaging tools, and extends such tools to include what we call enhanced presence: a way of monitoring the availability of (and interacting with) fellow students and tutors at a distance. We describ
DESIGNING A TOOLSET FOR THE PRIME
VIRTUAL BUSINESS ENVIRONMENT
The PRIME (Providing Real Integration in Multi-disciplinary Environments) project1 aims in modeling, creating and evaluation of a Virtual Business Environment (VBE) for learning the entire life cycle of products and processes for all involved stakeholders and for gaining practical experience in strategic manufacturing through serious gaming. The paper presents the overall architecture of the PRIME system. Further it discusses in more detail the design of the game toolset, which provides the user
Margarita Engle: 2010 National Book Festival
Author Margarita Engle appears at the 2010 National Book Festival. Speaker Biography: Margarita Engle is a Cuban-American author of young adult novels in verse. "The Surrender Tree" received a Newbery Medal, Pura Belpre Medal, Jane Addams Award, Americas Award, Claudia Lewis Award and Lee Bennett Hopkins Honor. Her first picture book was "Summer Birds: The Butterflies of Maria Merian." Her most recent work is "The Firefly Letters: A Suffragette's Journey to Cuba" (Henry Holt). Based on the diar
The Service Architecture in the ACTIVEMATH Learning Environment
We discuss the usage of web-services in the ACTIVEMATH learning environment, describe the prototypes implemented and the experience gained. Requirements for an ideal web-service technology are described. They include the notion of event propagation as well as the consideration for stateful web-services. Finally we propose models to make the web-services of ACTIVEMATH available to client components without affecting privacy or security. Further work, within the LE ACTIVEMATH EU project is describ
Atmospheric Black Carbon alters Weather Patterns (Still images)
Simulations of effects of black carbon aerosols on temperature, precipitation, and radiation flux. This version presents stills from two different simulations (for comparison). For experiment A, black carbon is added based on INDOEX measurements while experiment B is run with no black carbon aerosols.
Statistics for Laboratory Scientists I
This course introduces the basic concepts and methods of statistics with applications in the experimental biological sciences. Demonstrates methods of exploring, organizing, and presenting data, and introduces the fundamentals of probability. Presents the foundations of statistical inference, including the concepts of parameters and estimates and the use of the likelihood function, confidence intervals, and hypothesis tests. Topics include experimental design, linear regression, the analysis of

Sex, Money, Happiness and Death: The Quest for Authenticity
Manfred Kets de Vries, Raoul de Vitry dâ€™Avaucourt Clinical Professor of Leadership Development and Director of the INSEAD Global Leadership Centre, takes readers out of their comfort zone in his latest book, which has grown out of his conviction that many business academics have lost touch with the people they should be trying to help. His aim is twofold: to persuade executives to take time out to reflect on what really counts in their lives and to shake academics down from their ivory to
The NASA Health Stabilization Program
This NASA Sci Files segment describes the NASA Health Stabilization Program, a quarantine system for soon-to-fly astronauts. Produced specifically for students and is suitable for elementary and older students.
(This is an Emmy award-winning series of instructional programs that introduces students in grades 3-5 to NASA and integrates mathematics, science, and technology through the use of Problem-Based Learning (PBL), scientific inquiry, and the scientific method. The series seeks to m
This Flash based applet simulates data from a case study of treatments for tumor growth in mice. This simulation allows the user to place mice into a control and treatment groups.
In this module you will study the motion of a vibrating string under undamped and damped conditions. There are interactive exercises to link everyday experiences with mechanics and mathematics. In particular, you will derive the equation which governs the motion of a vibrating string; study the motion of a vibrating string in a vacuum and in a fluid; compare real experimental data with theoretical predictions. Integrating the concepts of higher math with their applications in science and engine

Nano-Scale Device Simulations Using PROPHET-Lab Exercise 1
These are companion exercises for two lectures offering practical guides to the use of a general device simulator (PROPHET) available on nanoHUB.org. PROPHET is a partial differential equation (PDE) solver that offers users the flexibility of integrating new models and equations for their nano-device simulations. The first lecture covers the basics of PROPHET, including the set-up of simulation structures and parameters based on pre-defined PDE systems. The second lecture uses examples to illust
Based on UNICEF's annual flagship publication, The State of the World's Children report (SOWC), the U.S. Fund for UNICEF has developed and released these free resources for educators to use with students in grades 3-12. The lesson plans and resources in these units are designed to be used sequentially or separately. Topics include addressing global affairs issues such as the Millennium Development Goals, real life stories from youth, the causes of childhood exclusion, and water and sanitation.
