Vorgelegt von
Nikol Rummel aus Kenzingen

Wintersemester 2003/2004 Diese Arbeit entstand im Rahmen des DFG-Projektes „Netzbasiertes kooperatives
Lernen mit ausgearbeiteten Kooperationsbeispielen und Kooperationsskripts bei
komplementärer Expertise“ von Prof. Spada und Prof. Caspar (Sp 251/16-1 und -2).
Das Projekt ist Teil des DFG-Schwerpunktprogramms "Netzbasierte
Wissenskommunikation in Gruppen", initiiert von Prof. Hesse (Tübingen), Prof.
Hoppe (Duisburg) und Prof. Mandl (München).

Research and progress in academia are not possible without mentors and advisors,
colleagues, assistants and friends. I want to take this opportunity to thank some
people who have been important to my dissertation work.
First and foremost I want to thank my advisor Prof. Hans Spada for his neverending
support over the past three years. The constructive dialog and collaboration with
Hans Spada have been a great experience that I would wish every doctoral student
could have. I have greatly enjoyed working with him and learned a great deal over
these years.
I am very thankful to the DFG who has made my work possible by financing me
through the research project and through the Virtual PhD Program (VGK). Without
this support, the research and conference activities that I was able to participate in
over the past three years – and thus also the dissertation itself – would not have been
possible.
Along these lines, I would like to acknowledge a number of people that have
supported my research over the past three years, as mentors in the VGK or in other
contexts. In particular: Prof. Rainer Bromme, Prof. Friedrich Hesse, Prof. Paul
Kirschner, Prof. Ken Koedinger, Prof. Joel Levin, Prof. Rolf Plötzner, Prof.
Alexander Renkl, and Prof. Gerhard Strube.
Sincere thanks go to Jörg Spirik and Michael Stumpf who have supported the project
and dissertation work on the technical side.
On the practical side of the dissertation, I would further like to thank Mary Leonard
from UW-Madison for helping with the English language editing.
In addition, I wish to thank a number of people that have contributed to the success
of this work in many different ways: the student research assistants of the DFG-
project, Dejana Diziol, Jana Groß Ophoff, Anne Meier, Friederike Renner, and
Katrin Schornstein; Miriam Bertholet, Julia Härder, Ingo Kollar and the other
doctoral students of the VGK; Ina Jucks, Frank Fischer, and Armin Weinberger,
colleagues from the Special Priority Program. You have been important discussion
partners, role models and company while progressing through my dissertation work!
Last, but surely not least, I want to thank my parents, sisters, brother, and my friends
for creating a supportive environment for my life and work. Above all, my thanks
and appreciation go to my partner Claus Binder. Table of Contents
