Everyday, students and teachers had to fill out several
questionnaires, but spending no more than 20 minutes
altogether per day on it, except for the Inventar Sozialer
Kompetenzen – ISK (Kanning 2009, see chapter III How
does Design Thinking contribute in developing 21st century
skills?), which was filled out by the students in their regular
class settings before and after the workshop. To see what
impact the workshop had – if any – on the social skills of
students, pre-post comparisons (that is: gain-scores) were
calculated. In sum, students of the Design Thinking
condition profit more than students of the Dewey-condition.
Even though not all differences in gain-scores are large
enough to reach statistical significance, the picture is pretty
consistent: In an eighteen out of 21 scale the gain-scores
are more favourable for Design Thinkers. In particular, the
gain-scores differ with statistical significance (p < .05) on
the following scales, favouring Design Thinking: SelfExpression,
Direct Self-Attention, Self-Monitoring and
Reflexibility. Close to significant (p < .1) are differences of
gain-scores on the following scales: Assertiveness, Flexibility
of Action, Indirect Self Attention and Person Perception.
