Enligt Palloff och Pratt (citerade i Li, 2003 och Muirhead, 2004) vill den virtuella studenten ha: 1) kommunikation och återkoppling

2) interaktivitet och en känsla av gemenskap, och

3) adekvat vägledning och möjlighet att utföra de uppgifter som krävs för kursen.

I virtuellt arbete finns det i allmänhet fyra typer av beteenden att fokusera på: deltagande, respons, känslomässig feedback och riktade meddelanden (Horman, 2005; Burge, 1994 citerad i Muirhead, 2004). Följande faktorer är särskilt viktiga för ett effektivt beteende

1) graden av social närvaro;

2) kvaliteten på den feedback som erhålls

3) dialogens intellektuella djup, och

4) lärarens virtuella närvaro (Berge, 2002; Gunawardena, 1995; Swan, 2001 citerad i Muirhead, 2004).

European university networks interconnect

To simplify a complex network architecture, the MUPBED project is initiating a vertical system. The objective: to allow users to exchange a maximum of data.

Sharing information within European university networks can be complex, especially when it comes to large data sets, such as VOIP or video. "Someone in a European university has to go through different networks and technologies before they can reach a colleague in another institution," says Jan Spaeth, coordinator of the MUPBED project. "And the problem is that often the quality of the connection does not allow them to share as much information as they would like." To find a quick and easy way to share data at these different levels, the MUPBED project was developed. The solution: find a way to vertically connect these networks. Because in order to connect researchers and professors to each other, there is a three-tiered architecture, which makes interconnectivity more difficult.

Creating links between tiers

The first tier is the network that connects a campus by linking the various research buildings and departments together. The second level is the network that connects each university network on a national scale. Finally, the highest level is the European level, which groups all the national ones. MUPBED has developed the following system: when a user does a research on a specific subject, he uses a particular bandwidth, and then an automatic connection is established between the network levels. The latter then communicate with each other, and provide the result to the user. At the heart of the solution is a network resource optimization system that ensures that bandwidth is only activated when it is needed.

Optimal capacity

The researchers tested the system by conducting video conferences between several participants spread across Europe, requiring high bandwidth. Another test was to send large data from one network to another, among the three different levels. And according to them, the results were conclusive. In each case, the applications established the links between the necessary networks using all the bandwidth they needed. Once the task was completed, the bandwidth returned to its optimal capacity and the links were broken.

iTunes U : American universities share their knowledge

Apple's iTunes Store now offers the possibility to improve one's knowledge thanks to the courses taught in the most famous American universities.

Innovating can mean creating a new product, but it can also mean finding other uses for a pre-existing product. This is the second solution that Apple has chosen with the iTunes Store, its famous music and video download catalog. The latter has been transformed into an e-learning system by integrating a new free section, iTunes U. Among other things, it offers the possibility of downloading courses from major American universities.

The university as if you were there...

iTunes U(niversity) offers users educational programs, laboratory experiments and campus visits from the largest American universities, such as Stanford, Berkeley, Duke and MIT (Massachusetts Institute of Technology MIT Open Learning). But for now, all of this content is only available in English.

"The iTunes U makes it easy for anyone to access educational materials from many prestigious colleges and universities in the United States. Education is a lifelong process and we are pleased to make it possible for everyone to download courses, speeches and other academic content for free," said Eddy Cue, vice president of iTunes.
