Our school’s problem of practice includes specific, immediate corrective feedback. A resource I found includes a descriptive teacher feedback rubric that can be used by groups or individual teachers who want to improve their formative assessment practice: Using the Formative Assessment Rubrics, Reflection and Observation Tools to Support Professional Reflection on Practice By: Caroline Wylie and Christine Lyon, Educational Testing Service May 2013. There is a particular rubric on page 56 dealing with descriptive teacher feedback that I found most helpful. It is read from left to right and describes an incomplete implementation to a more advanced level of implementation focusing on the teacher’s role to provide feedback.
