The study reported in this paper is an ongoing effort. We reported a preliminary analysis of the data in the paper. The current experiments varied the subjects to c- duct online group learning activities by the communication media such as email and threaded discussion. Although, we could have easily learned the impact of mobile devices in learning if we divided the subjects to use different hardware such as p- sonal computers, personal digital assistant, or mobile phones, we believe our findings will still be able to provide useful insights on the difficulties that the mobile learners will face in solving problems as a group. Our analysis result will also provide ba- line information on whether the traits of the successful or failed online groups are applicable to the mobile learners. For example, we expect the SMS will be a better medium to overcome the major problem of instant communication or the rapid propagation of the information as the mobile phones have built-in mechanism to remind the users of the incoming new messages and also the mobile phone users are expected to be interrupted for the incoming messages. However, we need further investigation of other problems, which hinder the optimum online group work. For example, ‘accuracy of the transferred information’ was identified as one of the pr- lems of using emails as the communication medium. Personal Digital Assistant (PDA) or SMS are more apt to deliver shorter messages than the typical emails.

Conceptual modeling represents a recent approach to creating knowledge. It has emerged in response to the computer revolution, which started in the middle of the 20th century. Computers, in the meantime, have become a major knowledge media. Conceptual modeling provides an answer to the difficulties experienced throughout the development of computer applications and aims at creating effective, reasonably priced, and sharable knowledge about using computers in business. Moreover, it has become evident that conceptual modeling has the potential to exceed the boundaries of business and computer usage. This state-of-the-art survey originates from the International Seminar on the Evolution of Conceptual Modeling, held in Dagstuhl Castle, Germany, in April 2008. The major objective of this seminar was to look into conceptual modeling from a historical perspective with a view towards the future of conceptual modeling and to achieve a better understanding of conceptual modeling issues in several different domains of discourse, going beyond individual (modeling) projects. The book contains 14 chapters. These were carefully selected during two rounds of reviewing and improvement from 26 presentations at the seminar and are preceded by a detailed preface providing general insights into the field of conceptual modeling that are not necessarily discussed in any of the chapters but nevertheless aid in conceptualizing the inner structure and coherence of the field. The chapters are grouped into the following three thematic sections: the evolution of conceptual modeling techniques; the extension of conceptual modeling to a service-oriented, peer-to-peer, or Web context; and new directions for conceptual modeling.

From a Historical Perspective Towards the Future of Conceptual Modeling

The Evolution of Conceptual Modeling

Der "Rohstoff Information" ist heute einer der zentralen strategischen Erfolgsfaktoren im Marktgeschehen. Die Bedeutung eines methodischen Vorgehens bei Planung, Herstellung, Nutzung, Wartung und Außerbetriebnahme von Informationssystemen kann deshalb kaum überschätzt werden. Informationssysteme bilden daher auch den Schwerpunkt der Angewandten Informatik und der Wirtschaftsinformatik. Es ist somit kein Zufall, wenn die Fachgruppe EMISA nicht nur eine der ältesten, sondern auch eine der mitgliederstärksten Fachgruppen der Gesellschaft für Informatik ist. - Die EMISA-Fachtagungen sind ein Forum für intensive Diskussion über die Grundlagen von Informationssystemen, Methoden ihrer Herstellung und Anwendung, der Bewertung ihrer Qualität sowie ihrer Modifikation. Der vorliegende Tagungsband zeichnet ein eindrucksvolles Bild des "state of the art".

This book constitutes the refereed proceedings of UNISCON 2008 held in Klagenfurt, Austria, during April 22-25, 2008. UNISCON combines the ECOMO workshop series and the ISTA conference series. The 19 papers dealing with conceptual modeling, model-driven software development and information systems applications represent a 30% selection from the original set of submissions. They are completed by two keynote lectures and 35 papers from internationally renowned researchers, invited in honor of Heinrich C. Mayr, whose 60th birthday is also celebrated at this event, that he originally created.
