Abstract

Dual scaling, a variation of multidimensional scaling, can reveal the dimensions underlying scores, such as rater's judgments. This study illustrates the use of a dual scaling analysis with semi-structured interviews of raters to investigate the differences among the raters as captured by the dimensions. Thirty applications to a one-year post-Bachelor's degree teacher education program were rated by nine teacher educators. Eight of the raters were subsequently interviewed about how they rated the responses. A three-dimensional model was found to explain most of the variance in the ratings for two of the questions and a two-dimensional model was most interpretable for the third question. The interviews suggested that the dimensions reflected, in addition to differences in rater's stringency, differences in their beliefs about their roles as raters and about the types of insights that were required of applicants.
