Exploring the Relationship between Static and Dynamic Vertical Scaling from Cross-Sectional and Longitudinal Design Perspectives
Wang, Shudong; Jiao, Hong; Jiang, Yanming
Online Submission, Paper presented at the Annual Meeting of the National Council on Measurement in Education (NCME) (San Diego, CA, Apr 13-17, 2009)
The concept of dynamic vertical scaling (DVS) from longitudinal point of view has been proposed as comparing to traditional vertical scaling or static vertical scaling (SVS) from cross-sectional perspective. The effects of differences between DVS and SVS on large-scale student achievements have been investigated. The potential application of DVS on creating or explaining students growths was explored. In general, DVS can account for many factors that could affect students growth where SVS has limitations on its cross-sectional design for applications unless strong assumptions has to be made. Appended is: Longitudinal Linear and Nonlinear Models Used to Generate Data. (Contains 8 tables and 9 figures.)
