## Reflection: Trust and Respect Circles Unit Assessment - Section 1: Look at Student Work Samples from Arcs and Angles Menu

While it takes time to go through students’ work on the Circles Menu to select student work and justification samples, I have found that this is one of the most authentic ways to get students to tangibly identify for themselves what goes into a high quality justification as opposed to a mediocre, sometimes lengthy, sometimes sparse, explanation.  I called on Recorder/Reporters to share out on behalf of their group, asking them to provide evidence in the student work.  Students were able to say “this work seems well justified because they were able to clearly name the relationship they used” or “this doesn’t seem like a justification at all...it kind of feels like the student just explained what they did, step-by-step, without taking about how they knew they could do that.”  I felt that it was so powerful for students to describe their peers’ work so clearly and articulately.
