Investigating Design Features of Descriptive Graphic Rating Scales.
Myford, Carol M.
Applied Measurement in Education, v15 n2 p187-215 2002
Studied the use of descriptive graphic rating scales by 11 raters to evaluate students' work, exploring different design features. Used a Rasch-model based rating scale analysis to determine that all the continuous scales could be considered to have at least five points, and that defined midpoints did not result in higher student separation reliabilities. Nor were scales with more hatchmarks more or less reliable than those with fewer hatchmarks. (SLD)
