Two existing measures, the SCOOP Notebook and the Classroom Assessment Scoring System
(CLASS) served as a foundation for M‐Scan measurement development. The SCOOP measure
used classroom artifacts, observations, and instructional materials to measure mathematics
instructional practices (Borko et al., 2005; Borko, Stecher, & Kuffner, 2007). The M‐Scan
selected, defined, and adapted eight dimensions from the SCOOP measure. The structure of
the coding protocol and the 1 to 7 scale was based on the Classroom Assessment Scoring
System (CLASS; Pianta, Hamre, & LaParo, 2007). Coding guidelines were established with
descriptions to correspond to numerical ratings from 1 to 7 (segmented as low [1‐2], medium
[3‐5], and high [6‐7]).
