Freedom to learn instead of forced studying. Non authoritarian but instead based on consent, it would be the teachers main job to awaken the interest of the children and to help them find and improve their talents, so the children would then be enabled to do self determined learning and studying because they actually want to and not because they are forced to.

Diversity instead of uniformity. No grades and no compulsory subjects but instead individual tutoring of every child/student, based on their personal interests and talents.

Classes taking place outside and in places that are relevant for the topic being studied is the norm
