Students' perceptions of instructional quality are among the most important criteria for evaluating teaching effectiveness. The present study evaluates different latent variable modeling approaches (confirmatory factor analysis, exploratory structural equation modeling, and bifactor modeling), which are used to describe these individual perceptions with respect to their factor structure, measur...

Methods of statistical process control were briefly investigated in the field of educational measurement as early as 1999. However, only the use of a cumulative sum chart was explored. In this article other methods of statistical quality control are introduced and explored. In particular, methods in the form of Shewhart mean and standard deviation charts are introduced as techniques for ensurin...

A vertical score scale is needed to measure growth across multiple tests in terms of absolute changes in magnitude. Since the warrant for subsequent growth interpretations depends upon the assumption that the scale has interval properties, the validation of a vertical scale would seem to require methods for distinguishing interval from ordinal. In taking up this issue, two different perspective...

A computer aided design system for determining the color appearance of metallic automotive coatings has been developed. A sketch based bidirectional reflectance distribution function design interface allows simple concept art to be used to style new metallic car colors. The final design is specified using industrial measurement standards for metallic color appearance, and paint formulations are...

The Computer-Based Alternative Assessment (CBAA) project is concerned with finding ways to answer these questions for all levels of students from elementary through university. Project activities involve developing and testing alternative means to enhance educational assessment with confidence measurement, analysis of self-awareness, and performance evaluation. The research demonstrates how com...

To gain analytical insight into whether input resources matter in public education, a Becker/Peltzman/Stigler model of the determination of local educational budgets and outputs by political authorities is constructed. The model results are consistent with empirical findings that resources don’t matter, even when all schools are efficient, if errors in measurement and specification occur. When ...
