DOCUMENT RESUME

Selection the best Method of Equating Using Anchor-Test Design‎ in Item Response Theory ‎‎

Explaining the problem. The equating process is used to compare the scores of the two different tests with the same theme‎. ‎The goal of this research is finding the best method of equating data using Logistic model. ‎ Method. we are using the data of Ph.D‎. ‎test in Statistic major for two consecutive years 92 and 93‎. ‎For analyzing‎, ‎we are specifically using the tests of Statistics major ...

IRT 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 ...

Fair and Equitable Measurement of Student Learning in MOOCs: An Introduction to Item Response Theory, Scale Linking, and Score Equating

Email [email protected] Abstract Massive open online courses (MOOCs) are playing an increasingly important role in higher education around the world, but despite their popularity, the measurement of student learning in these courses is hampered by cheating and other problems that lead to unfair evaluation of student learning. In this paper, we describe a framework for maintaining test securi...
