摘要
垂直等值是为了刻画学业发展而出现的,有锚题、等组和等测验三种基本设计,发展性分数量表构建的基本方法有Hieronymus、Thumton和IRT三种。随着实际需求及相关测量领域方法的发展,垂直等值从本身的理论基础、方法以及在测验领域的应用在近些年得到了很大的发展。但是垂直等值技术本身仍不够成熟。在实施的各个环节仍需大量深入研究。
Vertical scaling is used for describing achievement growth. It includes three basic designs: commonitem, equivalent group and scaling test and three basic scaling methods: Hieronymus, Thurston and IRT scaling. There is a rapid advance in vertical scaling from the theory, methods to the application in testing in recently years. However, it still needs much more deeper researches.
