Shin, Tacksoo – Asia Pacific Education Review, 2012
This study introduced various nonlinear growth models, including the quadratic conventional polynomial model, the fractional polynomial model, the Sigmoid model, the growth model with negative exponential functions, the multidimensional scaling technique, and the unstructured growth curve model. It investigated which growth models effectively…

Kang, Taehoon; Chen, Troy T. – Asia Pacific Education Review, 2011
The utility of Orlando and Thissen's ("2000", "2003") S-X[squared] fit index was extended to the model-fit analysis of the graded response model (GRM). The performance of a modified S-X[squared] in assessing item-fit of the GRM was investigated in light of empirical Type I error rates and power with a simulation study having…

Kim, Se-Kang – Asia Pacific Education Review, 2010
The aim of the study is to compare longitudinal patterns from Mathematics and Reading data from the direct child assessment of Early Child Longitudinal Study, Kindergarten (ECLS-K, US Department of Education, National Center for Education Statistics 2006), utilizing Profile Analysis via Multidimensional Scaling (PAMS). PAMS has been used initially…

Kim, Changdai; Min, Kyung Wha; Yune, Sook Kyeong; Choi, Hanna; Gong, Eun Hye – Asia Pacific Education Review, 2008
This study examined employees' perceptions of interpersonal competence at work through the research methodology known as concept mapping. The purpose of this study was to identify the phenomenally derived components of interpersonal competence in work environments and employees' underlying cognitive structures of interpersonal competence at work.…

Min, Kyung-Seok – Asia Pacific Education Review, 2007
Most researchers agree that psychological/educational tests are sensitive to multiple traits, implying the need for a multidimensional item response theory (MIRT). One limitation of applying a MIRT in practice is the difficulty in establishing equivalent scales of multiple traits. In this study, a new MIRT linking method was proposed and evaluated…

Shin, Tacksoo – Asia Pacific Education Review, 2007
This study introduces three growth modeling techniques: latent growth modeling (LGM), hierarchical linear modeling (HLM), and longitudinal profile analysis via multidimensional scaling (LPAMS). It compares the multilevel growth parameter estimates and potential predictor effects obtained using LGM, HLM, and LPAMS. The purpose of this multilevel…
