Description

Abstract
本計畫提出全面性差異試題功能(DIF)檢核程序,以在探索性DIF檢核情境中,對測驗進行所有組別變項(例如:性別)的同時DIF檢核。此程序以先定錨後檢核策略為基礎,整合變數選擇法則(例如:正規化估計法),能在不具備DIF先驗知識的情況下檢核DIF。在學術上,此計畫將DIF檢核概念化為變數選擇問題,能提供測驗學家後續研究、執行DIF檢核的新取向;在實務上,此程序所具備的彈性,能充分因應測驗實務中可能遭遇的情境(例如:large p/n ratio),協助測驗實務者進行全面性DIF檢核。本計畫預期此全面性DIF檢核程序,能有效確保測驗在所有組別變項下的公平性與效度。
