After my 1:1 I needed to change my keyword search because I am embarking on a slightly different path and I was able to come up with some interesting things. Two of articles focused mainly on differentiation in the classroom which has been a common theme with most of research but I came across one article that discussed a complete classroom restructure and replacing it with multi-age classrooms according to students developmental level K-3 and 4-5.
Because my essential question is geared more towards all students having equal access to learning, this article explored an new idea of what that might look like compared to those I have researched in the past.
Katherine Schweitzer (2015) notes that when students finish early this often becomes a time that is difficult for classroom management as students look for other ways to occupy their time. In theory multi-age classrooms address such issues as multi-level learners, ELD, disciplinary behaviors, etc. However teachers will need to make significant shifts in teaching because there is no curriculum and the idea doesn't support grade level testing.
I personally like the idea and have seen similar school structures thrive at Montessori and private schools where family members of mine attend. I don't see this happening anytime soon in our public schools though. I find small group instruction and interventions inside the school setting the best way I can really teach similar developmental students but even then after a while they began to realize which kids are in the "smart group and the "dumb" group which can make or break certain kids.
