Write about what is your idea of a happy school where learning is an engaging and joyful activity.
I imagine such a school to give autonomy to students. They are taught from an early age to manage their own choices and the time they will dedicate to studying. For instance, students could choose which subjects to study that semester. Teachers would then present them with ideas on how to get started, on which topics there are to be seen at the level for that subject, etc. Students and teachers would then agree on how much time would be applied to each topic. Students would study with the help of peers as well as of teachers. However, teachers would be more like guides than authority figures.
