Reel American History Project
The general goal of the Reel American History project is to foster critical thinking about a matter of enduring cultural attention, especially where young people are concerned: the formation of our national identity. Reel American History is designed to be a "Collaborative Shared Resource". It aims at being a large, ongoing, cumulative, collaborative project that involves many students and many faculty over a long period of time. We strive to engage students in authentic learning – making st
COSEE Great Lakes Workshops
These asynchronous workshops focus on environmental topics related to the Great Lakes region. Subjects covered include: The solid earth system; The bedrock and formation of the Great Lakes; Life and Rocks: Current geological processes; Human impacts [vice-versa!]; and Ocean/lake deep exploration (sink holes, underwater archeology, NOAA's exploration book) studying the bottom, characteristics of the water at depth.
Gas Particles in Motion
We are constantly being exposed to the behavior of gases. Each time we pump up a tire, blow up a balloon, use a spray can, or experience the cooling of gases as they escape from a gas storage container, we are reminded of how gases behave with changes in temperature, volume, pressure, or number of particles. In an astronomical scale, we know that star formation involves contraction of gas clouds to produce dense, high-pressure cores capable of fusion reactions. These labs will help your students
Treasure Hunt in Alaska
This is a Web-based story of three children who venture out to find their great-grandfather's treasure box that was lost in the remote state of Alaska. Using simple terminology, the story integrates complex Earth and Space science concepts, such as the formation of gold deposits and the operation of satellites. The children model creative thinking, acquire and interpret radar images, plan a treasure hunt, work systematically, and learn about Alaska. They also exhibit the successes and setbacks o

Ontology-aware systems in AI-ED research
This paper discusses long-term perspectives of AI-ED research aiming at giving a clear view of what we need for further promotion of the research from AI and ED point of view. An analysis of the current status of AI-ED research is done in the light of intelligence, conceptualization, standardization and theory-awareness. Then, ontology-based architecture with appropriate ontologies is proposed. Ontological engineering of IS/ID is next discussed followed by a road map towards an ontology-aware
Participating Virtually to a Scientific Conference: A Collaborative E-Learning Scenario for Authenti
This paper presents a collaborative e-learning scenario inspired by socio-constructivist and situated learning theories which encourage authentic learning. Developed for a graduate distance education course, this scenario requires students to participate virtually in an asynchronous scientific conference. This paper presents the learning scenario, the technological environment developed to implement this scenario, as well as the results of a preliminary investigation which examines students p
Ontological Engineering of Instruction: A Perspective
How to scaffold the students to design experimental procedures? A situation experienced by 108 high-
This paper presents a proposition to improve the construction of concepts when doing experimental activities, and, in fact, to improve the construction of sense in experimental activities. This research involved 108, 17-18 year old students designing an experimental procedure for palaeontology learning. We first developed an analyse of the expert procedure and second, we realised a teaching sequence in which students were led to design an experimental procedure to measure the facial angle of a c
This deliverable describes the O'CoP ontology. It first presents the method used for building the ontology, and then details the results of each phase, as well as our return of experience for each step. The ontology obtained from analysis of information sources from eleven CoPs involved in Palette is composed of a concept hierarchy and a relation hierarchy, with concepts related to Community, Actor, Competency, Learner-profile, Collaboration, Process/Activity, Decision-making and Resource. We al

Inside the Oval Office
As staff secretary to President Dwight Eisenhower from 1954 to 1961, General Andrew Goodpaster was the person most privy to Eisenhower's thinking and key decisions during his White House years. Goodpaster began his long affiliation with Eisenhower as a staff officer under his leadership of the Supreme Headquarters Allied Powers Europe (SHAPE), and he went on to become the president's right-hand man on security matters. In this video segment, Goodpaster describes the inter-service rivalries that
'Way Downtown' combines animated and electronically enhanced still images with scenes of public life from an Asian culture. In the opening sequence a still image is slowly animated to show frantically ticking clocks. Images from advertising and mass media are juxtaposed against scenes of window washers and street crowds. Driving rock music, 'Guitar Trio,' by Rhys Catham accompanies the work. The piece is approximately eight minutes long and was broadcast as a segment of episode 303 (1987) of 'Ne
