The success of teaching is depending on a couple of factors: on how
far students are involved into lectures, on the material, its
completeness and on co-learning of students. Involvement of students
into lectures means, being able to follow the thoughts of the
teacher, ask questions and make comments. The material must be
presented in a suitable form and essential parts of it have to be
available during the whole learning process, for preparing
participation in lectures and exercises as well as for exams. For
more effective learning and training of social abilities, working in
groups of co-learners has to be encouraged. Mobile and ubiquitous
computing offer new possibilities to achieve these goals by
increasing the awareness in class and supporting an active
participation of students. By promoting existing concepts and
enabling new ways of application sharing, the project SASCIA (System
architecture supporting cooperative and interactive applications)
aims at developing a framework for multiple applications to support
teaching in collocated, remote and hybrid scenarios. Its core is
composed of components to capture and distribute context information
about sessions, participants and those applications that are used
during a lecture or encounter among students. A configurable floor
control was designed to cope with a wide spectrum of applications
and learning situations. For some cases, even a control for semantic
consistency can be necessary. In combination with a suitable user
and session management, a whiteboard for annotations and a recording
facility to support latecomers as well as subsequent replay, these
components are providing the required functionality. As a
consequence, SASCIA offers remote control and viewing facilities to
all participants during lectures and co-learning sessions. That
means, usage of a lot of facilities like applications, pointing and
annotating in application windows are available to everyone by
leaving teachers the right to interrupt at any time. All public
annotations as well as private ones can be stored and replayed
afterwards. By offering state information about everybody in class
with proper regard of privacy concerns, participants are enabled to
address each other more personally. This holds especially for
teachers getting direct feedback on their presentation. For
discussions without a teacher being present, SASCIA provides
collaborative ways of experiencing teachware and a voting mechanism
to support ad hoc encounters and peer relations among participants.
As demonstrated by measurement values with a first prototype, the
performance of the whole system is acceptable. Further evaluation
and experiments in real class situations are planned for the next
semesters.
