Measurement Study

Developing New Measures of Teachers' Instruction: Part 2

One of the guiding questions for C-SAIL’s Measurement Study is, “How reliably can raters code the content of teachers’ assignments and assessments?”

We find that raters can code mathematics assignments quite reliably, but that they struggle to code English language arts (ELA) assignments. In this post, we discuss why we think this finding is important and what the implications are for our and others’ work.
