Home Truths about the Housing Market
The sub-prime mortgage crisis and the credit crunch that has followed in its aftermath are taking their toll on the housing market. On August 28, the S&P Case-Shiller U.S. National Home Price Index fell 3.2% in the second quarter. According to the National Association of Realtors, the inventory of unsold homes is at a record high. As sales have fallen, many home builders have seen their stock prices drop by more than 60% during the past year. How serious is this situation? Is there light at the
The U.S. Auto Industry: Dangerous Curves Ahead?
Among the U.S. auto industry's many challenges are the ongoing negotiations between General Motors and the United Automobile Workers union aimed at coming up with a new contract to replace the one that expired on September 15; the recent takeover of Chrysler by private equity firm Cerberus Capital Management; and a possible slowdown in consumer spending as a result of fallout from the subprime mortgage crisis. Meanwhile, industry watchers are awaiting the outcome of reported efforts by India's T
It Is a Bird...a Plane...a Recession, Or Is It?
It's been quite a week. Stock markets around the world showed sharp declines on Monday; on Tuesday, the Federal Reserve cut its benchmark interest rate by three-quarters of a percentage point. The rate cut helped stem the losses on some indexes, but by January 23, the volatility had returned. The obvious fear is one of recession -- a possibility that the White House and Congress are trying to avert by coming up with a stimulus package that will keep the economy off life support. How effective wi

One War We Shouldn't Avoid: A New Approach to Reducing the Cost of Future Catastrophes
In 2005, three major hurricanes -- Katrina, Rita and Wilma -- struck the U.S. Gulf Coast area, causing not just death and destruction, but also leading to insurance payments and federal disaster relief of more than $180 billion. Today, say the authors of a new book titled, At War with the Weather: Managing Large-Scale Risks in a New Era of Catastrophes, the U.S. is even more vulnerable to catastrophic losses. Written by Howard Kunreuther and Erwann Michel-Kerjan, with colleagues Neil Doherty, Ma

Participatory design in open education: a workshop model for developing a pattern language
Technologically enhanced learning environments raise complex challenges for their designers, developers and users. Design patterns and pattern languages have recently emerged as a potential framework for addressing some of these challenges. However, the uptake of design patterns has been slow outside of the computer science community. We argue that this is largely a consequence of a weak positioning of pattern languages, as a form of delivering expert knowledge to layperson, and suggest an alter

We present here the prospective remote laboratory system with data transfer using Intelligent School Experimental System (ISES) as hardware and ISES WEB Control kit as software. This approach e
Cultures in negotiation: teachers acceptance/resistance attitudes considering the infusion of
A teachers training project, employing teacher-mentored in-school training approach, has been recently initiated in Greek secondary education for the introduction of Information and Communication Technology (ICT) into the classroom. Data resulting from this project indicate that although teachers express considerable interest in learning how to use technology they need consistent support and extensive training in order to consider themselves able for integrating it into their instructional pra
Promoting Self-Directed Learning in Simulation Based Discovery Learning Environments Through Intell
Providing learners with computer-generated feedback on their learning process in simulation-based discovery environments cannot be based on a detailed model of the learning process due to the "open" character of discovery learning. This paper describes a method for generating adaptive feedback for discovery learning based on an "opportunistic" learning model that takes the current hypothesis of the learner and the experiments performed to test this hypothesis as input. The method was applied in
Analysing the mechanisms of common ground in collaborative web-based interaction
The ideas presented in this paper are challenged especially by the certain critical questions concerning web-based interaction and the qualitative analysis of such interaction and learning. The question arises whether the students from different contexts and countries are able to reach such interaction that would lead them to educationally relevant higher-level discussion and learning in web-based environments. Furthermore, as this field of study is fairly novel, there is a shortage of establish
Constructing knowledge through a role-play in a web-based learning environment
This study aimed to find out how and on what level the students of two separate secondary schools shared and constructed knowledge on imperialism by interacting through historical role characters in a Web-based environment. Furthermore, the study aimed to find out how social and contextual features affected the nature of knowledge sharing and construction. The data about the history project were gathered by various means in order to validate the findings of the case study. The results demonstrat
