Multi-step procedures in STACK tasks with adaptive flow control

Digital exercises are increasingly becoming a mainstay of mathematics and engineering lectures worldwide. The time when digital tasks were only used to realize analog computational tasks with a schematic solution process and a check of the final result is long gone. In the meantime, didactically valuable and challenging tasks are being designed, with STACK taking a leading role in their realization. The further developments of STACK are correspondingly diverse and dynamic. One such further development, which is not yet part of the current STACK release, is the adaptive flow control of the solution process depending on the intermediate results in complex tasks. In this paper the technical realization is discussed, the added value is illustrated by two examples and finally an outlook on future planning is given.
