Understanding whether or not different types of students master various attributes can aid future learning remediation. In this study, two-level diagnostic classification models (DCMs) were developed to represent the probabilistic relationship between external latent classes and attribute mastery patterns. Furthermore, variational Bayesian (VB)…

This research empirically evaluates data sets from the National Center for Education Statistics (NCES) for design effects of ignoring the sampling design in weighted two-level analyses. Currently, researchers may ignore the sampling design beyond the levels that they model which might result in incorrect inferences regarding hypotheses due to…

An item sampling model for achievement testing with items scored in an arbitrary number of categories is investigated. (Author)

The third section of this two-volume report examines the utility of the model developed in section I for application in a classroom testing situation. The model was applied in arithmetic classes through a weekly testing program. The teacher specified the generic task being taught, tests were constructed using a table of random numbers to select…

A review of the literature about practices in evaluating art education programs led to the design of the new evaluation model described in this paper. The literature review revealed that a growing number of authors advocate qualitative methods, and that a debate exists regarding the combination of qualitative and quantitative data gathering and…

This technical memorandum describes courses which have been monitored by the Project for Comprehensive Achievement Monitoring (Project CAM, formerly known as Project CRAM). The course structures range from very structured through differentially paced programs for blocks of students to individually paced programs. Project CAM has guided the…

This study explored the assumption that the percentile rank of a group of students should be expected to remain the same on a post-test as on a pretest when the treatment of the group in the intervening period was the same as the treatment of the norms population. This assumption is basic to the use of the norm-referenced model for the assessment…

Data from Project Talent are utilized to assess the representativeness of the samples used in the Wisconsin and the Exploration in Equality of Opportunity (EEO) surveys. Adequacy of the measures of academic aptitude and aspiration used in the surveys are examined, and problems with the Wisconsin model are briefly discussed. (RM)
