The residual differential item functioning (RDIF) detection framework was developed recently under a linear testing context. To explore the potential application of this framework to computerized adaptive testing (CAT), the present study investigated the utility of the RDIF[subscript R] statistic both as an index for detecting uniform DIF of…

Recent works on Intelligent Tutoring Systems have focused on more complicated knowledge domains, which pose challenges in automated assessment of student performance. In particular, while the system can log every user action and keep track of the student's solution state, it is unable to determine the hidden intermediate steps leading to such…

We conducted a skills analysis on written expression curriculum-based measurement (WE-CBM) tasks completed by 117 second-grade students. As part of the skills analysis, we scored two WE-CBM tasks (i.e., narrative and expository) for correct and incorrect writing sequences, common writing errors, and sentence structures. Although a majority of…

Task-based language teaching (TBLT) and task-supported language teaching (TSLT) are often seen as incompatible as they draw on different theories of language learning and language teaching. The position adopted in this article, however, is that both approaches are needed especially in instructional contexts where 'pure' task-based teaching may be…

In a university third-year instrumental chemistry laboratory students build a laser based polarimeter for determining light scattering with commercially available optical components used in modern optics research laboratories. During this laboratory experiment, students learn that solutions containing molecules which scatter light also influence…

While feedback is widely considered essential for second language (L2) writing development (Bitchener & Ferris, 2012), teachers may not always be able to provide their learners with immediate and frequent corrective feedback. Automated writing evaluation (AWE) systems can help respond to this challenge by providing L2 learners with written…

In this secondary analysis study, the authors explored the relations between reading comprehension and oral reading performance in fourth-grade students, using a data set from the U.S. National Assessment of Educational Progress (NAEP) special study of oral reading. The data set consisted of 1,713 students randomly selected from the 140,000 fourth…

Cuisine and restaurants are powerful tools for cultural, social and tourist image-building, and projection for tourist promotion, particularly in the case of major tourist places and destinations which boast a well-deserved, long-standing history and reputation for gastronomical beacons. When menus are not properly translated (or transcreated)…

Purpose: The authors provide a review of the psychometric properties of 6 norm-referenced tests designed to measure children's phonological error patterns. Three aspects of the tests' psychometric adequacy were evaluated: the normative sample, reliability, and validity. Method: The specific criteria used for determining the psychometric…

Inspection of thousands of student responses to computer-marked assessment questions has brought insight into the errors made by adult distance learners of science. Most of the questions analysed were in summative use and required students to construct their own response. Both of these things increased confidence in the reliability of the…

Jaw movement patterns were examined longitudinally in a 3-year-old male with childhood apraxia of speech (CAS) and compared with a typically developing control group. The child with CAS was followed for 8 months, until he began accurately and consistently producing the bilabial phonemes /p/, /b/, and /m/. A movement tracking system was used to…
