As a training & development expert I laughed out loud when I read this.
Some participants LOVE theory – give them sources and concepts, reports & ruminations, inspirations & ideas, as well as books & bibliographies.
Some participants LOVE action – give them activities & exercises, puzzles & practice time, as well as scenarios & simulations.
Put the theory & action together & you’ve got powerful learning. It’s called praxis (a term from popular education pedagogy).
