概要	Rubric development is the systematic design of criterion-referenced scoring guides for judging complex performance such as writing, projects, presentations, and problem solving. A rubric specifies the dimensions on which work is evaluated and describes, in ordered levels, what each degree of quality looks like. Done well — as the syntheses by Andrade and by Jonsson and Svingby show — rubrics make scoring more reliable and transparent, clarify expectations for students, and turn assessment into a tool for learning rather than merely a verdict.	Generalizability Theory is a psychometric framework that decomposes observed score variance into multiple sources — persons, items, raters, occasions, and their interactions — using analysis of variance. It replaces the single reliability coefficient of classical test theory with a family of coefficients that tell researchers how well scores generalize across different measurement conditions.
