Differential item functioning (DIF) assessment attempts to identify items or item types for which subpopulations of examinees exhibit performance differentials that are not consistent with the performance differentials typically seen for those subpopulations on collections of items that purport to measure a common construct. DIF assessment…

A two-stage adaptive test and a conventional peaked test were constructed and administered on a time-shared computer system to students in undergraduate psychology courses. (The two-stage adaptive test consisted of a routing test followed by one of a series of measurement tests.) Comparison of the score distributions showed that the two-stage test…

Most human gradings of essays are holistic, or "overall." Therefore, Project Essay Grade (PEG), an attempt to develop computerized grading of essays, has concentrated most of its research on overall grading. It has successfully simulated human judges. However, since computer grading is less expensive than human grading, PEG has also…

Chapters in this book present the challenges and dilemmas faced by researchers as they created new computerized assessments, focusing on issues addressed in developing, scoring, and administering the assessments. Chapters are: (1) "Beyond Bells and Whistles; An Introduction to Computerized Assessment" (Julie B. Olson-Buchanan and Fritz Drasgow);…

National Assessment of Educational Progress writing sample essays from 1988 and 1990 (495 and 599 essays) were subjected to computerized grading and human ratings. Cross-validation suggests that computer scoring is superior to a two-judge panel, a finding encouraging for large programs of essay evaluation. (SLD)

Item response theory (IRT) has become one of the most popular scoring frameworks for measurement data. IRT models are used frequently in computerized adaptive testing, cognitively diagnostic assessment, and test equating. This article reviews two of the most popular software packages for IRT model estimation, BILOG-MG (Zimowski, Muraki, Mislevy, &…

This paper describes a new ICT assessment tool that reduces multihandling of marks, comments and scores specifically where professional judgement is involved. Whereas previous ICT applications in most fields of education have focused on student learning, this tool focuses on the lecturer task of the assessment process. Unlike many ICT based…

In computer-based interactive environments meant to support learning, students must bring a wide range of relevant knowledge, skills, and abilities to bear jointly as they solve meaningful problems in a learning domain. To function effectively as an assessment, a computer system must additionally be able to evoke and interpret observable evidence…

A new sharing item response theory (SIRT) model is presented that explicitly models the effects of sharing item content between informants and test takers. This model is used to construct adaptive item selection and scoring rules that provide increased precision and reduced score gains in instances where sharing occurs. The adaptive item selection…

Modern applications of computerized adaptive testing (CAT) are typically grounded in item response theory (IRT; Lord, 1980). While the IRT foundations of adaptive testing provide a number of approaches to adaptive test scoring that may seem natural and efficient to psychometricians, these approaches may be more demanding for test takers, test…

Recent years have seen widespread adoption of automatic grading of physics homework problems. Although first-generation homework management systems provide feedback and assign scores based only on the answers, problem-solving performance on exams seems to be no worse for students using these systems than for those who receive detailed comments…

This paper describes the implementation of a computer-based approach to scoring open-ended problem lists constructed to evaluate student and practitioner clinical judgment from real or simulated records. Based on 62 previously administered and scored problem lists, the program was written in BASIC for a Heathkit H11A computer (equivalent to DEC…

The recent psycholinguistic-sociolinguistic trend in foreign language teaching indicates a shift of interest away from quantitative data towards qualitative information of different kinds. Validity and relevance are stressed and so new test formats are demanded, as well as new methods of dealing with student answers. Item analysis techniques used…

FITNESSGRAM, a computerized program for scoring and reporting students' physical fitness status based on specific tests, has been a resounding success in the Tulsa, Oklahoma, public schools. The program provides feedback to students and permits evaluation of physical fitness efforts on a school-by-school basis. (PP)

Comparison of special education teacher (n=18) and computer-scored curriculum-based measurements (CBM) of spelling found that computer scoring accuracy was significantly higher and more stable. Additionally, high correlations were found between the CBM spelling scores and a standardized test of spelling achievement. (DB)
