Automated Essay Scoring Effect on Test Equating Errors in Mixed-format Test

Scoring constructed-response items can be highly difficult, time-consuming, and costly in practice. Improvements computer technology have enabled automated scoring of items. However, the application without an investigation test equating lead to serious problems. The goal this study was score mixed-format tests automatically with different test/training data rates investigate indirect effect these scores on compared human raters. Bidirectional long-short term memory (BLSTM) selected as method for best performance. During process, methods based classical theory item response were utilized. In most methods, errors resulting from close occurring processes conducted by It concluded that applied because it is convenient terms equating.
