Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides an overview of major developments around diagnostic classification models (DCMs) with regard to modeling, estimation, model checking, scoring, and applications. It brings together not only the current state of the art, but also the theoretical background and models developed for diagnostic classification. The handbook also offers applications and special topics and practical guidelines how to plan and conduct research studies with the help of DCMs. Commonly used models in educational measurement and psychometrics typically assume a single latent trait or at best a small number of latent variables that are aimed at describing individual differences in observed behavior. While this allows simple rankings of test takers along one or a few dimensions, it does not provide a detailed picture of strengths and weaknesses when assessing complex cognitive skills. DCMs, on the other hand, allow the evaluation of test taker performance relative to a potentially large number of skill domains. Most diagnostic models provide a binary mastery/non-mastery classification for each of the assumed test taker attributes representing these skill domains. Attribute profiles can be used for formative decisions as well as for summative purposes, for example in a multiple cut-off procedure that requires mastery on at least a certain subset of skills. The number of DCMs discussed in the literature and applied to a variety of assessment data has been increasing over the past decades, and their appeal to researchers and practitioners alike continues to grow. These models have been used in English language assessment, international large scale assessments, and for feedback for practice exams in preparation of college admission testing, just to name a few. Nowadays, technology-based assessments provide increasingly rich data on a multitude of skills and allow collection of data with respect to multiple types of behaviors. Diagnostic models can be understood as an ideal match for these types of data collections to provide more in-depth information about test taker skills and behavioral tendencies.

Available in PDF, EPUB and Kindle. Book excerpt: During the past two or three decades, research in cognitive science and psychology has yielded an improved understanding of the fundamental psychological nature of knowledge and cognitive skills that psychological testing attempts to measure. These theories have reached sufficient maturity, making it reasonable to look upon them to provide a sound theoretical foundation for assessment, particulary for the content of assessments. This fact, combined with much discontentedness over current testing practices, has inspired efforts to bring testing and cognitive theory together to create a new theoretical framework for psychological testing -- a framework developed for diagnosing learners' differences rather than for ranking learners based on their differences. This volume presents some initial accomplishments in the effort to bring testing and cognitive theory together. Contributors originate from both of the relevant research communities -- cognitive research and psychometric theory. Some represent collaborations between representatives of the two communities; others are efforts to reach out in the direction of the other community. Taking fundamentally different forms, psychometric test theory assumes that knowledge can be represented in terms of one or at most a few dimensions, whereas modern cognitive theory typically represents knowledge in networks -- either networks of conceptual relationships or the transition networks of production systems. Cognitively diagnostic assessment is a new enterprise and it is evident that many challenging problems remain to be addressed. Still, it is already possible to develop highly productive interactions between assessment and instruction in both automated tutoring systems and more conventional classrooms. The editors hope that the chapters presented here show how the reform of assessment can take a rigorous path.

Available in PDF, EPUB and Kindle. Book excerpt: Cognitive diagnostic models (CDMs; DiBello, Roussos, & Stout, 2007) have received increasing attention in educational measurement for the purpose of diagnosing strengths and weaknesses of examinees’ latent attributes. And yet, despite the current popularity of a number of diagnostic models, research seeking to assess model-data fit has been limited. The current study applied one of the Bayesian model checking methods, namely the posterior predictive model check method (PPMC; Rubin, 1984), to its investigation of model misfit. We employed the technique in order to assess the model-data misfit from various diagnostic models, using real data and conducting two simulation studies. An important issue when it comes to the application of PPMC is choice of discrepancy measure. This study examines the performance of three discrepancy measures utilized to assess different aspects of model misfit: observed total-scores distribution, association of item pairs, and correlation between attribute pairs as adequate measures of the diagnostic models.

This book was released on 2023-03-10 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a resource for those who are new to intelligent tutoring systems (ITSs), as well as those with a great deal of experience with them. This is the tenth book in our Design Recommendations for Intelligent Tutoring Systems book series. The focus of this book is on Strengths, Weaknesses, Opportunities, and Threats (SWOT) Analyses of varying components of ITSs. Each chapter in the book represents a different topic area, and includes a SWOT analysis that is specific to that topic and how it relates to ITSs. This book can be read in order, or a reader can choose a specific topic area and move directly to that chapter. Each SWOT Analysis describes the current state of the topic area, and how the lessons learned from the analysis could be applied to the Generalized Intelligent Framework for Tutoring (GIFT) (Sottilare et al., 2012; Sottilare et al., 2017). GIFT is an ITS architecture that is open-source, modular, and domain independent (Sottilare et al., 2017). Each book in the design recommendations series has addressed a different ITS topic area, and how the work in each chapter can relate to and inform the GIFT architecture. GIFT has continually been in development, with features consistently being added to improve functionality, as well as reduce the skill requirement for authoring content in GIFT. GIFT is freely available in both downloadable and Cloud versions at https://www.GIFTtutoring.org.

Download or read book Effective Cognitive Diagnostic Assessment with Computerized Adaptive Testing written by Teck Yong Lawrence Neo and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Educators are seeking out mechanisms for reporting diagnostic information about the strengths and weaknesses of each student. Cognitive diagnostic assessment (CDA) is a form of assessment that could facilitate the educators in discovering their students' strengths and weaknesses. In CDA, the examinees are classified according to the specific attributes (ability, skills, and knowledge) that the examinees possess. There are numerous models for cognitive diagnostic assessment. A higher-order latent trait model was used in the study. This model takes into account the local dependencies of the attributes by using a higher-order latent trait to model the mastery of the attributes. Another benefit for using a higher-order latent trait model is that it allows for concurrent estimation of the examinees' higher-order latent trait as well as his or her mastery of the attributes. Equipping educators with reports on individual examinee's general ability together with his or her mastery states with respect to the attributes could lead to better tailored remediation. For example, more scaffolding might need to be provided to examinees with lower general ability, whereas those with higher general ability might require a different pedagogical approach. Computerized adaptive testing (CAT) is a mode of testing that has gained popularity in recent years, due to its advantages. It tailors the test according to the examinees' ability, that is, each examinee will receive items that are neither too easy nor too difficult. Consequently, CAT is a more efficient test mode compared to paper-and-pencil testing. With the advancement of technology, CAT became a viable option for test administration. The advantages that CAT have over paper-and-pencil testing make it an attractive option of administering CDA. The key to adaptive testing is the item selection rules. The item selection rules should be able to pick the item that closely matches the examinee's ability. Most CATs are based on item response theory (IRT) models. These IRT-based CAT and CDA adopt different evaluation framework for the examinees, which implies that IRT-based CAT methods cannot be directly applied for administration of CDA. Thus, new methods must be developed for a cognitive diagnostic computerized adaptive testing (CD-CAT). The efficiency of adaptive testing is known to be highly dependent on the ability of the item selection rules to pick the most appropriate item for the examinee at every stage of the testing. However, problems might arise if the most appropriate items are selected at every stage, without consideration for non-statistical constraints like item exposure rate and content-balancing. In practical situations, tests usually cover several content areas and have balanced content coverage. Thus content-balancing constraints are important for test construction. In addition, items that are known to many examinees could lose their powers for distinguishing examinees in terms of their abilities. Examinees with low ability might be able to answer these over-exposed items correctly because they could prepare the answers to these items beforehand. In short, for an item selection rule to have practical applications, it should be able to handle non-statistical constraints as well. Thus, the focus of this study is on item selection rules with mechanism for managing non-statistical constraints. This study examines the efficiency of two new item selection rules. A higher-order latent trait model was used for the study. Besides, being able to account for the local dependencies between the attributes, the model also allows for simultaneous estimations of the examinee's mastery state with respect to specific attributes and his or her higher-order latent trait. Providing educators with reports on individual examinee's general ability (a higher-order latent trait) together with his or her mastery states with respect to the attributes could lead to better tailored remediations. For example, more scaffolding might need to be provided to examinees with lower general ability, whereas those with higher general ability might require a different pedagogical approach. Two new item selection rules (VAS and SHAS) which are based on attribute-specific item discrimination index are proposed in chapter 2. The study suggests that the adapted Hybrid Kullback-Leibler index and the adapted versions of the new indices (A_VAS and A_SHAS) are be better suited for providing diagnostic feedback if a short test is used. These three adapted indices were able to recover the individual attributes with high degrees of accuracy. After 24 items had been administered, the three indices had correctly classified (examinees' classification matching their latent classes) about 73% of the examinees; while about 87% of examinees were classified correctly or "almost" correctly (examinees with at least seven out of eight attributes correctly classified). In terms of the accuracy in the general ability estimation, the three indices had produced a high level of bias and mean square errors. A longer test would be needed to obtain more accurate estimation of the general ability.

This book was released on 2010-07-24 with total page 631 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in Bayesian analysis and statistical decision theory is rapidly expanding and diversifying, making it increasingly more difficult for any single researcher to stay up to date on all current research frontiers. This book provides a review of current research challenges and opportunities. While the book can not exhaustively cover all current research areas, it does include some exemplary discussion of most research frontiers. Topics include objective Bayesian inference, shrinkage estimation and other decision based estimation, model selection and testing, nonparametric Bayes, the interface of Bayesian and frequentist inference, data mining and machine learning, methods for categorical and spatio-temporal data analysis and posterior simulation methods. Several major application areas are covered: computer models, Bayesian clinical trial design, epidemiology, phylogenetics, bioinformatics, climate modeling and applications in political science, finance and marketing. As a review of current research in Bayesian analysis the book presents a balance between theory and applications. The lack of a clear demarcation between theoretical and applied research is a reflection of the highly interdisciplinary and often applied nature of research in Bayesian statistics. The book is intended as an update for researchers in Bayesian statistics, including non-statisticians who make use of Bayesian inference to address substantive research questions in other fields. It would also be useful for graduate students and research scholars in statistics or biostatistics who wish to acquaint themselves with current research frontiers.

Download or read book Cognitive Diagnostic Analysis Using Hierarchically Structured Skills written by Yu-Lan Su and published by . This book was released on 2013 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation proposes two modified cognitive diagnostic models (CDMs), the deterministic, inputs, noisy, "and" gate with hierarchy (DINA-H) model and the deterministic, inputs, noisy, "or" gate with hierarchy (DINO-H) model. Both models incorporate the hierarchical structures of the cognitive skills in the model estimation process, and can be used for situations where the attributes are ordered hierarchically. The Trends in International Mathematics and Science Study (TIMSS) 2003 data are analyzed to illustrate the proposed approaches. The simulation study evaluates the effectiveness of the proposed approaches under various conditions (e.g., various numbers of attributes, test lengths, sample sizes, and hierarchical structures). The simulation study attempts to address the model fits, items fit, and accuracy of item parameter recovery when the skills are in a specified hierarchy and varying estimation models are applied. The simulation analysis examines and compares the impacts of the misspecification of a skill hierarchy on various estimation models under their varying assumptions of dependent or independent attributes. The study is unique in incorporating a skill hierarchy with the conventional DINA and DINO models. It also reduces the number of possible latent classes and decreases the sample size requirements. The study suggests that the DINA-H/ DINO-H models, instead of the conventional DINA/ DINO models, should be considered when skills are hierarchically ordered. Its results demonstrate the proposed approaches to analyzing the hierarchically structured CDMs, illustrate the usage in applying cognitive diagnosis models to a large-scale assessment, and provide researchers and test users with practical guidelines.
