Symba: a Framework to Support Collective Activities in an Educational Context
Symba is a Web-based framework designed to support collective activities in a learning context. It has been constructed with a double objective, (1) make students explicitly work out their organization and (2) provide tailorability features to allow the students to decide about the tools and resources they want to be accessible in order to achieve the tasks they have defined. Symba dissociates an organizational level and an activity level. The organization level allows students to organi
River City Project
As visitors to River City, students travel back in time, bringing their 21st century skills and technology to address 19th century problems. With funding from the National Science Foundation, we have developed an interactive computer simulation for middle grades science students to learn scientific inquiry and 21st century skills. River City has the look and feel of a video game but contains content developed from National Science Education Standards, National Educational Technology Standards, a
Discover and apply principles of genetic inheritance by studying the inheritance patterns of fruit flies in a virtual environment. You will work on a virtual lab bench from which you can order fruit fly mutants from a web merchant, mate the flies in an incubator, anesthetize flies for observation, examine flies under a microscope, and analyze the data from offspring to determine patterns of inheritance. Your task is to propose hypotheses, design experiments, and analyze and interpret the data fr
A Family Corresponds: Polish Immigrants in the Early 20th century
Many immigrants to the United States wrote letters back home. At the time they were written, the missives shaped the expectations of those who would soon make the same journey; today, they gave historians invaluable first-hand testimony of the immigrants' own experiences. These seventeen letters involved the children of a retired Polish farmer named Raczkowski. Adam Raczkowski went to the United States in 1904 with the financial assistance of his sister Helena Brylska [later Dabrowskis] and his
Spartan Sagas: Kent Johnson
Kent Johnson, who was recruited to Michigan State as a swimmer, earned a bachelor's degree from the College of Natural Science in 1991 and a medical degree from the College of Human Medicine in 1995. He recalls the "unique atmosphere of togetherness" he found on the swim team and how it helped him succeed. "The boys on the swim team took me in-made me a part of the Spartan family." Spartans--alumni, students, faculty, and staff. Have your own Spartan Saga to share? Go to http://spartansagas.
Students observe the relationship between the angle of a catapult (a force measurement) and the flight of a cotton ball. They learn how Newton's second law of motion works by seeing directly that F = ma. When they pull the metal "arm" back further, thus applying a greater force to the cotton ball, it causes the cotton ball to travel faster and farther. Students also learn that objects of greater mass require more force to result in the same distance traveled by a lighter object.

Field day at Pomona College
Four student athletes cross the finish line of a 100-yard dash cheered on by students on either side of the track at a Pomona College field day. Morris Cadwalader is leading in the second lane from the left. Carl Newman is in the far right lane. The old Pomona College gymnasium is in the background.
East Street Beck Covering
19th March 1938. This view shows construction of the East street Beck covering project in progress. Some men are leaning over the fence watching. In the background we see the Railway Viaduct and a large warehouse and some dwelling houses. At the left is the "The Calls" Church Army hostel for men. On the corner is a traffic diversion sign.
Defining the scope of responsibilities: the Great Lakes region
The return and reintegration of refugees and IDPs is one of the most pressing challenges faced by the international community today. Recently back from a visit to the Great Lakes region, UNHCR's Assistant High Commissioner for Operations will discuss the local settlement of refugees in Tanzania and the return and reintegration of refugees in Burundi. Dr Chaloka Beyani, Legal Advisor to the Secretariat of the International Conference on the Great Lakes, will situate this problem within the Great
Financial Crises And Crisis Economics: Past, Present And Future.
As early as 2005 Roubini speculated that house prices would soon sink the economy, and in 2006 warned the IMF that the United States was likely to face a catastrophic housing bust resulting in deep recession. Back then he was nicknamed 'Dr Doom' by the New York Times. In hindsight, economists have called him a prophet.
Al 88, Si 12 (wt%), eutectic alloy
This sample is a casting alloy of eutectic composition. From the melt a eutectic is formed between aluminium solid solution and virtually pure silicon. Slow solidification produces a very coarse microstructure. The eutectic comprises large plates of silicon in the aluminium matrix. This microstructure displays poor ductility due to the brittleness of large silicon plates. The microstructure is normally refined through either rapid solidification, which lets the silicon phase assume a fibrous fo
ME++ The Cyborg Self and the Networked City
Throughout history, humans have created unique physical spaces in which to live, work and socialize. But the digital age has completely transformed the places in which we conduct our affairs, according to William J. Mitchell. We don’t congregate at the town bank any more for financial transactions. We visit ATMs or bank online.
Innovative Leadership during Economic Crisis
The same institutional tenets guiding innovative management during good times needn’t waver during a downturn, even the present one, says Emmanuel Maceda. After two decades at Bain, one of the world’s premiere management consulting businesses, Maceda feels confident in his company’s practices and principles, which have g
Final Journey to the Hubble Space Telescope
Astronaut Mike Massimino returns to MIT and shares his experience on the Space Shuttle Atlantis (STS-125). Topics include the challenges of space walking while repairing the Hubble, having the right tools on hand for high stakes repairs, and the long hours of practice that lead up to the task.

Denialism: Media in the Age of Disinformation
A few hundred years after the Enlightenment, western civilization is rushing back to the Dark Ages. The causes are debatable, but, argue these science journalists, the public increasingly rejects the findings of science, from climate change to evolution, and is turning away from rationality and reason in general.
Bill Porter in Conversation with Howard Anderson
Some of the lessons Bill Porter picked up as a 13-year-old ranch hand in Colorado seem to have lasted a lifetime. When his boss told him to drive over a treacherous mountain pass into town for some chicken feed, Porter said he could not yet drive. He was told, “Just do it.” And when he faced taking a team of horses out to pas
The Gutenberg Parenthesis: Oral Tradition and Digital Technologies
Should we view the last 500 years or so of Western culture as a strange interlude, defined by printed page and other artifacts that once dominated the landscape but are now fading in relevance? In this forum, Thomas Pettitt makes the deliberately provocative case for a Gutenberg “Parenthesis” -- a period marked b
