This research aimed to develop a valid and reliable test to be used to detect sixth grade students' misconceptions and errors regarding the subject of fractions. A misconception diagnostic test has been developed that includes the concept of fractions, different representations of fractions, ordering and comparing fractions, equivalence of…

Recent advances have enabled diagnostic classification models (DCMs) to accommodate longitudinal data. These longitudinal DCMs were developed to study how examinees change, or transition, between different attribute mastery statuses over time. This study examines using longitudinal DCMs as an approach to assessing growth and serves three purposes:…

Classification consistency and accuracy are viewed as important indicators for evaluating the reliability and validity of classification results in cognitive diagnostic assessment (CDA). Pattern-level classification consistency and accuracy indices were introduced by Cui, Gierl, and Chang. However, the indices at the attribute level have not yet…

Introduction: While there is a general agreement on the theoretical importance of epistemological beliefs, the research area is struggling with the measurement of these beliefs. In this contribution, the use of drawings to ascertain epistemological beliefs is explored. Method: Three studies are described. In Study 1, we asked participants to draw…

Reliability and validity for three autism instruments were compared for 190 children with low functioning autism (LFA), 190 children with high functioning autism or Asperger's disorder (HFA), 76 children with attention deficit hyperactivity disorder (ADHD), and 64 typical children. The instruments were the Checklist for Autism Spectrum Disorder…

Six sociometric measures were evaluated on a sample of 85 four-year-olds from three preschool and day care centers. Stability, intercorrelations, and accuracy of classifying rejected children were compared for measures of social preference, social impact, peer ratings, alternative status, and positive and negative nominations. Test-retest…

Two studies investigated the functional equivalence of three different scoring systems used to assess the child's ability to understand and carry out multiplicative classification tasks. All three scoring criteria produced reliable and homogeneous tests. Their factor matrices were similar, and the corresponding factor structures were invariant…

This paper compares two methods of establishing content validity, forced-choice judgmental review and a latent category judgmental review. It also compares content validity evidence with the results of a scale reliability analysis and makes recommendations of the two content validity procedures. Two different groups of graduate students enrolled…

For six tests, coefficient delta as an index for internal optimality is computed. Internal optimality is defined as the magnitude of risk of the decision procedure with respect to the true score. Results are compared with an alternative index (coefficient kappa) for assessing the consistency of decisions. (Author/JKS)

The Armed Services vocational aptitude battery (ASVAB) was developed by a joint-service technical group, using items from the services' previously operational tests. The ASVAB was designed as a potential replacement for the Armed Forces Qualification Test and the separate classification batteries used by each of the services. Thus, the…

This report describes a study comparing the classification results obtained from a one-parameter and three-parameter logistic based tailored testing procedure used in conjunction with Wald's sequential probability ratio test (SPRT). Eighty-eight college students were classified into four grade categories using achievement test results obtained…

Classification studies are important for practitioners who need to identify individuals for specialized treatment or intervention. When interventions are irreversible or misclassifications are costly, information about the proficiency of different classification procedures becomes invaluable. This study furnishes information about the relative…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
