The demand for short and intense courses intended to teach new or
improve existing pragmatic ICT skills, required for solving a given
problem in a real context, has been raised especially by the industry.
We provide an example where a pragmatic coding school model has been
shown to be an effective way to teach new skills and enhance prior
knowledge in a short timeframe, among undergraduate computer science
students of the University of Namibia (UNAM). This paper presents a
coding school for climate service app development, organized jointly by
the University of Turku (UTU), Finland, and UNAM, at the UTU satellite
campus within the UNAM main campus. We describe the coding school's
design and implementation phases, as well as analyze lessons learned,
based on which we suggest actions to improve similar schools in the
future. Furthermore, we demonstrate a method by which the coding school
is linked to the requirements of an international research project
demanding local input in its co-design.
