Reviews problems involved in analyzing data on educational or training needs and details use of the proportionate reduction in error (PRE) approach (Hildebrand, et al., 1977), which predicts the probability that certain combinations of a joint distribution will occur, then tests to see how closely the prediction matches the observation. (MBR)

Presents the rationale, methodology, data analysis, and positive findings of an 11-year longitudinal study which investigated the effects of a technological intervention strategy (i.e., use of the talking typewriter, talking page, and voice mirror) on reading and reading comprehension at the Early Childhood Center at Drexel University.

Discussion of online bibliographic database searches focuses on a software system, SORT-AID/SABRE, that ranks retrieved citations in terms of relevance. Results of a comprehensive user evaluation of the relevance ranking procedure to determine its effectiveness are presented, and implications for future work are suggested. (10 references) (LRW)

The adequacy of linking statewide standardized test results to the National Assessment of Educational Progress by using equipercentile equating procedures was investigated using statewide mathematics data from four states. Results suggest that the linkings are not sufficiently trustworthy to make comparisons based on the tails of the distribution.…

A Monte Carlo study explores the robustness assumption in structural equation modeling of using a full information normal theory generalized least-squares estimation procedure on Type I censored data. The efficacy of the following proposed alternate estimation procedures is assessed: asymptotically distribution free estimator and a latent…

The general-information-theoretic approach was used to identify informational overlap and asymmetry between variables, using affective, cognitive, and behavioral measures. Using the chi-squared test, no significant differences were found in response rates, demographics, or patronage frequency of three stores between numerical (n=453) and graphic…

Effects of the following variables on performance of computerized adaptive testing (CAT) procedures for the partial credit model (PCM) were studied: (1) stopping rule for terminating CAT; (2) item pool size; and (3) distribution of item difficulties. Implications of findings for CAT systems based on the PCM are discussed. (SLD)

Changes in information retention resulting from changes in reliability and number of intervals in scale construction were studied to provide quantitative information to help in decisions about choosing intervals. Information retention reached a maximum when the number of intervals was about 8 or more and reliability was near 1.0. (SLD)

The continuous method of scoring a performance test composed of standardized patients was compared with a derivative method that assigned each of the 131 examinees (medical residents) a dichotomous score, and use of Angoff's method with these scoring methods was studied. Both methods produce reasonable means and distributions of scores. (SLD)

Ideally, there should be a global statistical picture of TVET presenting, for every country in the world, data such as: (1) Enrolment rates by gender, age and programme; (2) The relative proportions of people enrolled in general and vocational programmes; (3) The relative proportions enrolled in programmes provided by enterprises, government and…

A Texas district shows what can be done when school-based staff developers work with teachers dedicated to improvement--student achievement improves in just one year. The author points out the factors that helped make it work and offers tips for traps to avoid. (Contains 10 charts.)

With businesses struggling for resources during economic downturns, traditional business student internships were becoming more difficult to develop. One business school extended its experiential learning opportunities with specific management projects in community small business, healthcare, education, and non-profit organizations. The on-campus…

Drawing conclusions from the comparison of datasets using informal statistical inference is a challenging task since the nature and type of reasoning expected is not fully understood. In this paper a secondary teacher's reasoning from the comparison of box plot distributions during the teaching of a Year 11 (15-year-old) class is analyzed. From…

This report examines how immigrant students performed, mainly in mathematics and reading, but also in science and problem-solving skills in the PISA 2003 assessment, both in comparison with native students in their adopted country and relative to other students across all countries covered in the report (the "case countries"). In…

Hierarchical Bayes procedures were compared for estimating item and ability parameters in item response theory. Simulated data sets from the two-parameter logistic model were analyzed using three different hierarchical Bayes procedures: (1) the joint Bayesian with known hyperparameters (JB1); (2) the joint Bayesian with information hyperpriors…
