abstract = {IT systems have an ever-growing impact on society and
economy. Thus, the job market situation for IT specialists
is extremely positive, yet the number of students in the IT
sector is far too small to meet the current and increasing
demand. What might the problem be? What makes these jobs -
especially for young women - unattractive? How can this
situation be addressed?This dissertation has investigated
these and correlating questions. For this purpose, the image
that children and adolescents have of computer science and
computer scientists has been analyzed. In contrast to this
is the image which the computer science community aspires to
have. One way to inspire more young people about computer
science and in doing so, win them as a potential young
academics, is to build a Schülerlabor (an extracurricular
learning lab for students) for computer science. The choice
of placing this learning facility outside of school was
based, among other things, on the fact that computer science
as a subject in school is still overlooked in many German
states (especially in North Rhine-Westphalia, where this
work was performed).This thesis details the design,
construction, development, as well as a qualitative and
quantitative evaluation of InfoSphere, the learning lab for
computer science at the RWTH Aachen University, which has
been welcoming 4,122 students since it was founded in June
2010. Secondly, an evaluation of 1,349 records from students
on the topic of "the image of computer science" has been
performed, which, as an expansion of previous work, examines
children and adolescents from the 3rd grade level up to high
school graduates.The conception of the student lab included
decisions on equipment and the use of media and materials to
promote learning, and primarily the instructional design of
currently 27 computer science workshops for various topics
and different ages. The pedagogical emphasis lies on
learner-centered activities, so that children and
adolescents discover computer science autonomously.
Furthermore, the workshops promote the often under-perceived
aspects of computer science such as creativity, teamwork,
and its impact on everyday life. The concept of the
Schülerlabor was evaluated on the feedback from teachers as
well as didactics experts and moreover, was evaluated by 354
students’ records in greater depth, over the period from
January 2011 to October 2012.The mainly quantitative
evaluation with regard to the students' conceptions about
the discipline as well as the world of work by computer
scientists was implemented by means of an online-based
pre-post-test design. After some questions were asked about
the image of computer science in the first period, the
following questionnaires were then fully geared to address
the issue of "students' conceptions about computer science"
in November 2012. In the second period - from November 2012
to December 2013 - 116 complete records of primary school
children, and 879 responses from students of lower and upper
secondary were evaluated. Measurements were made on the
prevailing image of computer science (pretest), as well as
the changes arising from a visit to the InfoSphere, in
particular the effect of various modules
(post-test).Overall, interesting differences were found
between the sexes, in terms of both expectations for the
visit to InfoSphere, and in terms of their ideas about the
computer science discipline and IT professionals. For
example, girls see the technical aspects of computer science
in the foreground more than their male peers. This
statement, coupled with the fact that girls especially feel
that the technical aspects are of little interest, can
already be seen as a factor contributing to the low number
of women interested in computer science. These and other
exciting results are statistically analyzed in detail as
part of this dissertation. In this work, the different
instructional designs and thematic orientation of the
workshops are put in relation to the measured changes in
thinking in children and adolescents. In the outlook, many
ideas for the development of the learning lab can be found,
as well as the expansion of the research in the context of
the student’s perception of computer science.},
