How about a subject like Design in school. Rather than the same old boring teaching manuals in art, music, economics or social science, young learners have always been attracted to making things by themselves. The theoretical context is then coming to the subjects and objects more naturally. Economics as market design, design social security for platform workers, sound or furniture design could bring in the creative potential of the learners. Lessons learned through subsequent applications or realizations of prototypes allows the link of theory and practice. A school garden would even be a fantastic cross-discipline learning opportunity.
The most difficult part is probably to find competent coaches to guide the learners exploring and designing. The world is not perfect, so why should learners not be confronted with imperfections in learning set-ups. The most fun part in science is when experiments go wrong, hopefully not too badly though. Catching learners by their curiosity is very likely to get them hooked on more thorny scientific questions as well. Across Europe holidays are coming to an end and millions of pupils go back to their benches and rigid curricula. We should really care more about the next generation.
