An Examination of the Residual Covariance Structures of Complex Performance Exercises Under Various Scaling and Scoring Methods 2008 4325 Large-scale assessment programs are increasingly including complex performance exercises along with traditional multiple-choice items in a given test. These performance assessments are developed in part to measure sets of skills that are part of the ...
Modeling differential pacing trajectories in high stakes computer adaptive testing using hierarchical linear modeling and structural equation modeling 2006 1920 "This study compares two statistical methods for modeling changes in response latency (timing) patterns on a high-stakes adaptive test: (1) hierarchical linear modeling (HLM2) and (2) growth modeling using structural equation modeling (SEM). The test...
Relationships between examinee pacing and observed item responses: results from a multi-factor simulation study and an operational high stakes assessment 2009 1847 The use of response time in testing has a relatively long history, ranging from concerns over test speededness to using response times as performance indicators (e.g., speed and accuracy). This model-based investigation examined the relationship betw...
A comparison of traditional test blueprinting and item development to assessment engineering in a licensure context 2010 3214 With the need for larger and larger banks of items to support adaptive testing and to meet security concerns, large-scale item generation is a requirement for many certification and licensure programs. As part of the mass production of items, it i...
Detecting test cheating using a Deterministic, gated item response theory model 2010 6713 High-stakes tests are widely used as measurement tools to make inferences about test takers' proficiency, achievement, competence or knowledge. The stakes may be directly related to test performance, such as obtaining a high-school diploma, being gra...
Conditions affecting the accuracy of classical equating methods for small samples under the NEAT design: a simulation study 2011 4341 Small sample equating remains a largely unexplored area of research. This study attempts to fill in some of the research gaps via a large-scale, IRT-based simulation study that evaluates the performance of seven small-sample equating methods under va...
Data collection design for equivalent groups equating:using a matrix stratification framework for mixed-format assessment 2012 3222 Mixed-format assessments are increasingly being used in large scale standardized assessments to measure a continuum of skills ranging from basic recall to higher order thinking skills. These assessments are usually comprised of a combination of (a) m...
Item parameter changes and equating: an examination of the effects of lack of item parameter invariance on equating and score accuracy for different proficiency levels 2013 5794 The impact of particular types of context effects on actual scores is less understood although there has been some research carried out regarding certain types of context effects under the nonequivalent anchor test (NEAT) design. In addition, the iss...
The optimal design of the dual-purpose test 2013 1696 Traditional test development focused on one purpose of the test, either ranking test-takers or providing diagnostic profiles for test-takers. Embedding both the ranking and diagnostic purposes in one assessment instrument would be a great advancement...
An investigation on computer-adaptive multistage testing panels for multidimensional assessment 2013 2776 The computer-adaptive multistage testing (ca-MST) has been developed as an alternative to computerized adaptive testing (CAT), and been increasingly adopted in large-scale assessments. Current research and practice only focus on ca-MST panels for cre...
The effects of routing and scoring within a computer adaptive multi-stage framework 2014 1398 This dissertation examined the overall effects of routing and scoring within a computer adaptive multi-stage framework (ca-MST). Testing in a ca-MST environment has become extremely popular in the testing industry. Testing companies enjoy its efficie...
Principled assessment as a foundation for standard setting 2015 1230 This study investigated the impact of using Assessment Engineering (AE) task models as the unit of judgment in a standard setting workshop. The proposed method, or Task Model-based Standard Setting (TMSS), used a procedure similar to that of the Book...
A simulation study to investigate optimal equating anchor set construction practices under the NEAT design 2018 303 This study examines anchor set construction techniques in observed score test equating under the non-equivalent with anchor-test design. It differs from other studies in that it seeks to understand the interaction between the examinee abilities, test...
A comparison of observed score approaches to detecting differential item functioning among multiple groups 2018 346 The overall purpose of this dissertation was to compare various observed score approaches in detecting differential item functioning among multiple examinee groups simultaneously. Specifically, this study contributes to the literature base by investi...
Optimal characteristics of anchor tests in vertical scaling: a special case of non equivalent groups with anchor test (NEAT) design in vertical scaling 2019 106 There are multiple empirical issues and complications associated with vertical scaling methods that have not been sufficiently explicated even though there has been scanty research conducted within the general framework of the nonequivalent group wit...
Enemy item detection using data mining methods 2019 224 Enemy items are any two items that should not appear on the same test form. These items may address the same material, or one may provide clues about the answer to another. Most enemy item pairs are identified before forms are published; subject matt...
