I haven't used a behavior

I haven't used a behavior chart for a long time, for the reasons you outlined. They had become a time-sink in terms of clips and administering consequences, and they were undermining my relationships with the students.

I focused instead on making connections, on dealing with issues organically as they arose, and on giving kids more of a "buy in" to class harmony, and the results were amazing.

I had a brief look at things like ClassDojo but I wanted the classroom to function less on extrinsic motivation than on intrinsic, so ditched the outward rewards as well: no points, no slips of paper - all gone now.

If you want to move even further along the no-chart continuum - and really, is ClassDojo so different at its core? - I suggest looking at Alfie Kohn's and Dr. Ross Greene's work in school discipline.
