Chia-Wen's research focuses on Item Response Theory (IRT) models for forced-choice and compositional items, with applications in computerized adaptive testing (CAT), differential item functioning (DIF), and multilevel modeling. His work includes developing novel IRT methods for ranking items and Most-Least formats, addressing reliability/validity in educational scales like the Principal Instructional Management Rating Scale (PIMRS), and analyzing large-scale datasets (PISA) for cross-national educational insights.
Recent publications demonstrate expertise in ipsative testing, online parameter estimation, and factor mixture modeling for educational diagnostics. He has also contributed to methodologies for CAT algorithms in educational evaluation and fault line analysis in school leadership teams.
