The purpose of the study was to examine students' participation in career guidance activities as mechanism through which young adults are developed into productive, responsible personalities well equipped for life and work in today's technology based society. The study focused on career information search, career exploration and assessment aspects…

In this study, eight statistical strategies were evaluated for selecting the parameterizations of loglinear models for smoothing the bivariate test score distributions used in nonequivalent groups with anchor test (NEAT) equating. Four of the strategies were based on significance tests of chi-square statistics (Likelihood Ratio, Pearson,…

In the article "Exploring the Sensitivity of Horn's Parallel Analysis to the Distributional Form of Random Data," Dinno (this issue) provides strong evidence that the distribution of random data does not have a significant influence on the outcome of the analysis. Hayton appreciates the thorough approach to evaluating this assumption, and agrees…

This study uses Monte Carlo simulations to demonstrate that regression-discontinuity designs arrive at biased estimates when attributes related to outcomes predict heaping in the running variable. After showing that our usual diagnostics are poorly suited to identifying this type of problem, we provide alternatives. We also demonstrate how the…

This article presents a dual system model (DSM) of decision making under risk and uncertainty according to which the value of a gamble is a combination of the values assigned to it independently by the affective and deliberative systems. On the basis of research on dual process theories and empirical research in Hsee and Rottenstreich (2004) and…

Understanding instructors' perceptions of distance education transactions is becoming increasingly important as the mode of distance learning has become not only accepted, but preferred by many students. A need for more empirical data was evident as anecdotal information still dominates the research literature. The study focused on the faculty of…

The aim of the current study is to validate the invariance of major profile patterns derived from multidimensional scaling (MDS) by bootstrapping. Profile Analysis via Multidimensional Scaling (PAMS) was employed to obtain profiles and bootstrapping was used to construct the sampling distributions of the profile coordinates and the empirical…

Calculators are a controversial, yet widely used tool in mathematics education for all students and especially for students with disabilities. However, little research has explored calculators and students with disabilities. This paper explored the influence of calculator type (four-function and graphing) on the mathematical performance of…

The value of professional development continues to be emphasized on educational and governmental levels. Even as this study was being conducted, the U.S. Department of Education launched a $4.35 billion dollar grant that includes improving teacher effectiveness as a core component of the grant's purpose…

This paper presents a new technique in which covariates are controlled and evaluation data still are presented graphically in a manner that makes sense to policy makers. An illustration is provided using data drawn from an evaluation by the author of a major National Science Foundation (NSF) university funding program. (Author)

Demonstrates, with an example, a relatively simple method for fitting Bradford's law to empirical data to estimate the number of journals and articles in a subject collection. An exact discrete formulation illustrates Bradford's law as a special case of the Zipf-Mandlebrot "rank frequency" law. (Author/RAA)

Reviews the use of chi-square statistics for goodness of fit. Examines how to help students relate their earlier work with independence to the use of chi-square statistics. (KHR)

The assessment of individual or community nutritional status involves the use of indicators; when properly analyzed and interpreted, these may be used to decide what strategies to implement, or how to orient activities aimed at improving nutritional status. In primary health care programs, one approach which remains underused involves obtaining…
