School is over, but writing evaluations are not. Instead of grades, each teacher at school writes a yearly summary, but then writes an evaluation of each student, as best we can, highlighting the year's accomplishments and the future needs of each. I'm happy to take a break from that writing so I can share a little bit more about those units that I mention sometimes. At my school, each student chooses a particular topic around which the teacher (with student input) wraps the curricula. There are many other things our students do, but the main part of their schooling is the unit. They choose books, only sometimes related to the units. They do specific assignments related to the unit, but also as a class when the group is studying something particular. It's a little complicated, and differs with each student.
