I'm thinking of going with an alternative seating arrangement next year. Instead of desks or tables, I want to have a variety of seating options. Big floor pillows, bean bags, milk crates with padded tops, chairs, and tables would all be available and students could choose what they like. I'd like to do this because I'm concerned about an unfortunate combination of a terrible lack of space and abundance of students. I just can't fit enough desks and/or tables into my room to accommodate all my students. This is my solution. Before I bring my idea to the principal for permission, I'd like to have some data to support it, hopefully showing that it has some educational merit.
