The Search for the Hereditary Molecule
Using this simulation, you can manipulate virtual tubes of bacteria in a virtual lab to discover the transforming principle and recreate classic experiments in the discovery of DNA. How was the hereditary molecule isolated and identified? What decisions do we need to make as we recreate the lab work of researchers like Oswald Avery and his colleagues?

Going around in circles!: around and about a geometric figure
Geometry can be an exercise arena for strengthening those logic muscles that middle school students need to flex. When we work with a geometric figure—a circle, for instance—and apply the ancient tools of compass and straightedge, geometry can become a rich ground for developing design. And a circle has size, so a unit on this topic necessarily brings in the mathematics of its measurement. Circles, then, is a geometric topic that can provide mental challenge, opportunity for artistic develop

Gulag: Many Days, Many Lives
Millions of prisoners suffered the brutal assault on human dignity that was the Gulag. Many Days, Many Lives presents the history of this system through a browseable archive of video, art, artifacts, photographs, and the life stories of former Gulag prisoners. Online exhibitions take visitors on a thematic exploration of Gulag life, including a virtual tour of the reconstructed camp and museum made possible by the Gulag Museum at Perm-36. Teaching resources for introducing the Gulag's history in

Une typologie des fonctions des modèles formels : l'exemple de la biologie
Une typologie des fonctions des modèles est construite à partir dun cadre théorique (Nifle) permettant de définir le rapport entre modèle et expérience. Il est admis quil existe un lien entre la manière dont on modélise en tant quexpert ou chercheur et la manière dont on apprend à modéliser en tant quétudiant, et que ce lien repose sur le rapport expérience/modèle. La typologie est construite pour le cas particulier des modèles formels (utilisant un formalisme mathématiqu

Les avis individuels sont-ils pris en compte lors d'une activité collaborative à distance ? Quels
Cet article a pour objectif de mettre en évidence de quelle manière les avis individuels sont pris en considération lors d'une activité collaborative. Nous nous attacherons à vérifier tout d'abord dans quelle mesure les avis individuels des 96 sujets de notre échantillon se modifient ou non selon la modalité de travail collaboratif (modalités de constitution de la paire, consignes collaboratives visant ou non au consensus) à laquelle ils sont confrontés (question de recherche 1).

Introduction to Stoichiometry
Our on-line Chemistry course covers stoichiometry and demonstrates our scenario based approach to teaching chemistry. Traditional courses tend to follow a bottom-up approach to learning chemistry. This traditional approach teaches abstract concepts and tools before discussing their practical application, which results in students learning bits of unconnected knowledge that are rarely usable let alone memorable. In our approach, scenarios are used both to motivate the material and provide a frame

A Framework to Analyze Argumentative Knowledge Construction in Computer-Supported Collaborative Lear
Computer-supported collaborative learning (CSCL) is often based on written argumentative discourse of learners, who discuss their perspectives on a problem with the goal to acquire knowledge. Lately, CSCL research focuses on the facilitation of specific processes of argumentative knowledge construction, e.g., with computer-supported collaboration scripts. In order to refine process-oriented instructional support, such as scripts, we need to measure the influence of scripts on specific processes

Making sens: science education networks of sensors
A small group of leaders from research, industry, and education convened in a one-day workshop at Stanford's Center for Innovations in Learning (SCIL) to brainstorm on the use of data probes, sensors, and communication technologies in the development of innovative science education curricula. This report documents the results of a morning brainstorm and afternoon group exercises developing educational scenarios for which sensor networks would be powerful in enhancing learning content and promoti

Advanced video technologies to support collaborative learning in school education and beyond
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.

Eruption!
Eruption! is a volcanic crisis simulation model that showcases a series of villages that surround an active volcano and is part of the Interactive Models for Geological Education Online (IMGEO) series. The goal of the exercise is to preserve as many people and as much property as possible in spite of the threat from the volcano. Students role-play as villagers, the governor, volcanologists, and the press. The rules of the simulation, plus guides for teaching assistants and students, are availabl

The Virtual Body
The Virtual Body from MEDtropolis.com is an interactive overview of some of the basic structure and function of the human body. The site, available in both English and Spanish, is a mix of information and activities focused on four areas -- the brain, skeleton, heart, and digestive tract. The site's extensive array of diagrams and images, as well as its interactive nature, enhance the site's appeal and educational potential.

Middle School Portal: Math and Science Pathways (MSP2)
This virtual manipulative offers two modes for examining the patterns of multiples found on a grid displaying the numbers 2-200. In one mode, the student clicks a number on the grid, turning it red and removing all multiples of the number from the grid. This process can be repeated until only prime numbers remain. In the other mode, the student highlights one or two numbers, with multiples of the first turning red and the second blue. In both modes, number patterns and relationships can be obser

Welcome to the Dzanga-Sangha
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they take a close look at the interdependence of all living things in the Dzanga-Sangha. The site opens by introducing kids to BaAka, a young girl who will guide them through the site. In the Connect the Dots, an interactive game, kids learn how the people, animals, and plants depend on each other to thrive three habitats.

Antarctic Village - Metisse Flag
By way of calling the Orta Antarctic expedition to an end, the artists staged the first in a series of symbolic football games, ‘Heads or Tails, Tails or Heads’. Meteorologists, paleontologists and geologists from the Marambio Antarctic Base joined the Orta team to play a symbolic ‘All Nation’ match. The Metisse Flag and the Antarctic football shirts, created by the artists make it difficult to identify the adversary. The front and back of the players' shirts are stitched together with d
