Describes and evaluates a circuitless flow model for forecasting future student attributes and enrollment projections, compared with a simple Markov chain model. Data from a study of secondary students are used to illustrate the analytical methodologies and to contrast results of the Markov chain and circuitless flow models. (JG)

This report describes a statistically designed experiment that was carried out in an operational setting to determine the contributions of different sources of variation to the unreliability of scoring. The experiment made novel use of partially balanced incomplete block designs that facilitated the unbiased estimation of certain main effects…

Evaluates efficiency of a sample of Spanish secondary schools, focusing on the measurement model's theoretical specification and the "ex post" analysis of results. Highlights characteristics that differentiate the most efficient schools from the least efficient. Stresses the importance of employing information supplied by both…

In a multiple (or multivariate) regression model where the predictors are subject to errors of measurement with a known variance-covariance structure, two-sample hypotheses are formulated for (i) equality of regressions on true scores and (ii) equality of residual variance (or covariance matrices) after regression on true scores. The hypotheses…

Four experiments designed to study attitudes toward United States Presidents are described. The project uses the conceptual framework and methodology of a mathematical theory of information integration to compile information on attitudes and opinion formation based on high school civics and history courses. Results of the research findings of each…

Discusses some rapid statistical methods which are intended for use by physics teachers. Part one of this article gives some of the simplest and most commonly useful rapid methods. Part two gives references to the relevant theory together with some alternative and additional methods. (HM)

In studies involving matrix sampling on items, it is often the case that there are too few responses per individual to use latent trait item response models. A model is formulated wherein individual level variability appears as independent error within the cells of a cross classification of demographic variables. (JKS)

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…
