15 صفحه اولA Review of the Effects on IRT Item Parameter Estimates with a Focus on Misbehaving Common Items in Test Equating
Many studies have investigated the topic of change or drift in item parameter estimates in the context of item response theory (IRT). Content effects, such as instructional variation and curricular emphasis, as well as context effects, such as the wording, position, or exposure of an item have been found to impact item parameter estimates. The issue becomes more critical when items with estimat...

متن کاملIRT Observed-Score Kernel Equating with the R Package kequate
The R package kequate enables observed-score equating using the kernel method of test equating. We present the recent developments of kequate, which provide additional support for item-response theory observed score equating using 2-PL and 3-PL models in the equivalent groups design and non-equivalent groups with anchor test design using chain equating. The implementation also allows for local ...
