Krämer Bernd: Exposure and Support of Latent Social Networks Among Learning Object Repository Users

Although immense efforts have been invested in the construction of learning object repositories, the degree of reuse of learning resources maintained in such repositories is still disappointingly low. Various reasons have been identified as potential causes including: psychological barriers to make explicit use of foreign learning resources in higher education, concerns about the quality and composability of resources from disparate providers, usability and functional deficits of repositories, and disorientation of repository users. Inspired by the increasing acceptance of social software, we carried out an empirical study with the objective to address the disorientation issue by looking at recurring patterns of use and discovering latent communities of practice for the retrieval of reusable learning resources. Subject of investigation was LON- CAPA, a cross-institutional learning content management and assessment system used for nearly a decade now by currently more than 70 institutions, mainly based in the US. First we analyzed a plethora of log data collected over a period of three years. We revealed several kinds of connectivities among LON-CAPA users that gave rise to a few hypotheses about how these latent relationships may influence people’s selection of learning resources. These hypotheses were then verified both by collecting feedback from LON-CAPA operators and users. The latter had to answer a questionnaire addressing individual retrieval and evaluation strategies, including trust issues. In a third step we designed and implemented a few services that aim to enforce reuse behavior. They were combined with a social networking software that supports closed communities of practice. The enhanced functionality is currently used and validated by a subset of LON-CAPA users.

Maguire Gerald Q."Chip" Jr.: Applying computer science to solve problems: Step 1: Picking problems OR Being a contrarian - don't search under the lamppost

My standard advice to graduate students is:
The best problems to pick are:
(1) those that everyone says are _trivial_ - because some of them are _not_
(2) those that everyone says are _impossible_ - because some of them are _not_.

Find real problems - don't invent them. Being driven by real problems has lots of advantages:
(0) you can have a lot of fund
(1) you get to learn (a lot) of new things
(2) colleagues who will keep asking _why_? and _why_not_?
(3) you have to explain what you are doing to someone else who does not have the same approach or background as you do - both of you will learn in the process
(4) you can have an appreciative audience - if you can really improve the way that your collaborators can get their job done - so aim for order of magnitude effects

How do you know when you are successful:
(1) when you bankrupt the companies in the existing industry
(2) when you change the existing industry
(3) when others utilize/rip off your idea(s) and make their fortune or career with it/them
(4) when you make high level managers/administrators/... uncomfortable(or upset) because they see that you are destroying their business, organization, plans, etc.
(5) when the people who said "your are crazy" later say "but you were right"
(6) when you see someone smile because you just made their job a whole lot easier

The talk will be illustrated with examples from medical imaging, typesetting, mobile computing,data communications, ...

Ottmann Thomas: Of men and machines- More than 10 years of experience with electures at universities

Over the last decade the Computer Science Department of the University of Freiburg has gained a lot of experience with the production and use of electures poduced from live recordings. We review the origin of the tools used for presentation recording and emphasise the consquences of the object-based approach in contrast to screen grabbing. By extensive user studies and logfile analyses we revealed the preferences of users with respect to different formats of electures, navigational patterns, and ways of utilization. Though there are currently a number of different options for recording live presentations available, there are still a number of core features not solved satisfactorially. Therefore, we finally describe new developments possibly leadung to better systems.
