NASA space-based observatories are making unprecedented new discoveries and revealing worlds never before seen. During a televised panel discussion of leading science and engineering experts at NASA Headquarters on Monday, July 14, a scientific and technological roadmap to lead to the discovery of potentially habitable worlds among the stars was addressed. The agency's next step, the James Webb Space Telescope (Webb telescope), was featured as a new tool that will continue to help scientists rew
JeCo: Combining Program Visualization and Story Weaving
We present a collaborative learning tool for programming, Jeliot Collaboratively or JeCo. Jeliot Collaboratively is a combination of a program visualization tool for Java programs, called Jeliot 3, and a collaborative authoring tool, Woven Stories. We introduce these systems and explain how they can be used in learning. Furthermore, we present future directions in order to support a wider range of use cases with JeCo.

A Hierarchy of Ontologies for Didactics-Enhanced E-learning
Ontologies are a fundamental concept of the Semantic Web envisioned by Tim Berners-Lee . Together with explicit representation of the semantics of data for machine-accessibility such domain theories are the basis for intelligent next generation applications for the web and other areas of interest . Their application for special aspects within the domain of e-learning is often proposed to support the increasing complexity (, , , ). So they can provide a better support for course
Un modèle informatique de scénario fondé sur des pratiques réelles d'enseignement et une théori
La conception de scénarios pour un EIAH nécessite la mise en oeuvre de théories didactiques, de pratiques réelles, de modèles et de théories informatiques afin de prendre en compte les contraintes didactiques nécessaire à la modélisation de scénarios d'apprentissage. La modélisation de scénario devient ainsi une problématique pluridisciplinaire. La contribution principale de cet article est de proposer un modèle informatique de scénarios prenant effectivement en compte des contrai
A Programming by Demonstration Authoring Tool
for Model-Tracing Tutors
Model-tracing tutors have consistently been among the most effective class of intelligent learning environments. Across a number of empirical studies, these tutors have shown students can learn the tutored domain better or in a shorter amount of time than traditionally taught students (Anderson et al., 1990). Unfortunately, the creation of these tutors, particularly the production system component, is a time-intensive task, requiring knowledge that lies outside the tutored domain. This outside k
When less is sometimes more: Optimal learning conditions are required for schema acquisition from mu
While it is usually claimed that multiple examples for the illustration of problem categories are a necessary prerequisite for schema acquisition, there is a lack of conclusive empirical evidence supporting this claim. Moreover, there are findings indicating that carefully designed one-example conditions may allow for profitable processes of example comparison as well. In line with this reasoning, we present an experiment that builds up on a series of studies conducted by Quilici and Mayer (1
Contextualizing Discussions in Distance Learning Systems
In distance learning systems, communication tools are rarely integrated into learning activities, which does not encourage their use. The main goal of our work is to mitigate this lack of integration. Our aim is to bring the discussion activities closer to the learning activities, i.e. to situations to which the discussions must ideally relate to in order to promote learning between students. Thus, we suggest two models of forum which are contextual and based on a structuring of discussions resp

Un laboratoire distant est présenté : Educ@ffix.net, dans lequel les apprenants doivent construire un protocole dexpérience grâce à un environnement informatique dédié, puis réaliser cette expérience par lintermédiaire dun robot distant. Le protocole doit dabord être validé par un tuteur artificiel, puis la manipulation est exécutée par le robot et visualisée grâce à une caméra via le web. Dans ces conditions, lexpérience de chimie est modifiée par rapport à une si
Advanced video technologies to support collaborative learning in school education and
The aim of the paper is to characterize two new advanced video technology software systems developed for uses in collaborative learning (DIVER and HyperVideo2), and how they extend the paradigms of video use in classrooms today. The rationale for and characteristics of these tools are described, and early experiences with their use are characterized.
Beyond Amplification: Using the Computer to Reorganize Mental Functioning
Computers are classically viewed as amplifiers of cognition. An alternative conceptualization is offered of computer as reorganizer of mental functioning. Software analyses illuminate the advantages of the latter approach for new visions of the potential cognitive benefits of computers. A new result emerges: Because the cognitive technologies we invent serve as instruments of cultural redefinition (shaping who we are by changing, not just amplifying, what we do), defining educational values beco
Learning Design Engines as Remote Control to Learning Support Environments.
Context: Chapter 5 of the Learning Design book describes the operational model of a learning design engine based on the concept of finite automata with output alphabet. We rely on this event concept to include pre-existing learning tools in flexibe and rich learning designs. Contribution: We sketch an approach for the integration of complex learning environments in learning designs. Interactive learning support environments, such as argumentation or modelling tools are pre-existent and have a hi
Organisational patterns for e-learning centres
In this paper we explore the notion of using organisational patterns in educational design for the development of e-learning centres. We are using patterns to discuss some of the key aspects concerning the implementation of an e-learning centre within an institution, with an emphasis on the purposes and pedagogical principles that will help to successfully support such an initiative. The research approach which informed our pattern development work includes use of a qualitative survey of a set o
Beach marks on a polystyrene fracture surface
The fracture surfaces are generally very sharp and angular, indicating fast, brittle fracture with little ductile tearing. 'Beach marks', can be seen where the fracture has grown at a speed comparable to the speed of sound in the material. This results in periodic, momentary arrests in the crack propagation and periodic ridges in the fracture surface as it advances. There is also evidence of the fracture surface branching onto different planes as it progresses.
Racial/Ethnic Disparities in Preschool Immunizations: United States, 1996–2001
Objectives. We examined current racial/ethnic differences in immunization coverage rates among US preschool children. Methods. Using National Immunization Survey data from 1996 through 2001, we compared vaccination coverage rates between non-Hispanic White, non-Hispanic Black, Hispanic, and Asian preschool children. Results. During the 6-year study period, the immunization coverage gap between White and Black children widened by an average of 1.1% each year, and the gap between White and Hispa
A lesson in which students examine five examples of roadside architecture built in the 1920s and 30s to catch the eye of passing motorists. They include the Teapot Dome Service Station, the Big Duck poultry store, and the Benewah Milk Bottle.
Nineteenth Century America in Art and Literature
In the United States, the nineteenth century was a time of tremendous growth and change. The new nation experienced a shift from a farming economy to an industrial one, major westward expansion, displacement of native peoples, rapid advances in technology and transportation, and a civil war. In this lesson, works of art from the nineteenth century are paired with written documents, including literary selections, a letter, and a speech. As budding historians, students can use these primary source
