Sweden leaps ahead of the curve once more with my dream school; there are no grades, no classrooms and students learn together based on ability, not age.
Every part of the school is designed to engage students and facilitate learning, with areas for independent and collaborative work. It is more like a house than a school, with a flexible, welcoming feel.
This is, incidentally, the way HoneyFern is laid out (with less modern furniture). See previous blogs on grades.
