Purpose: We examined differential effects of cognitive impairment on each of the activities of daily living (ADL) and instrumental activities of daily living (IADL) tasks. Design and Methods: In a 3-year follow-up of community-dwelling elderly persons in Azuchi, Japan, we assessed cognition by using the Hasegawa Dementia Scale. We examined (a) the…

The crux in psychometrics is how to estimate the probability that a respondent answers an item correctly on one occasion out of many. Under the current testing paradigm this probability is estimated using all kinds of statistical techniques and mathematical modeling. Multiple evaluation is a new testing paradigm using the person's own personal…

Two new methods have been proposed to determine unexpected sum scores on sub-tests (testlets) both for paper-and-pencil tests and computer adaptive tests. A method based on a conservative bound using the hypergeometric distribution, denoted p, was compared with a method where the probability for each score combination was calculated using a…

The randomized response (RR) technique is often used to obtain answers on sensitive questions. A new method is developed to measure latent variables using the RR technique because direct questioning leads to biased results. Within the RR technique is the probability of the true response modeled by an item response theory (IRT) model. The RR…

Although differential item functioning (DIF) theory traditionally focuses on the behavior of individual items in two (or a few) specific groups, in educational measurement contexts, it is often plausible to regard the set of items as a random sample from a broader category. This article presents logistic mixed models that can be used to model…

This article uses data from the National Longitudinal Survey of Youth 1979-1998 to understand the differences between those who exited the welfare system voluntarily (leavers) and those who stayed (non-leavers), 1990-1996. The purpose of this research was to examine the differences between the groups in their personal and family characteristics,…

The purpose of this study was to investigate the effect of gender and grade level on students' logical thinking abilities. A total of 174 sixth, seventh, and eighth-grade students participated in the study. Test of Logical Thinking (TOLT) was administered to determine students' reasoning abilities. A two-way multivariate analysis of variance…

With growing numbers of drug-involved offenders, substance abuse treatment has become a critical part of corrections. A multistage therapeutic community implemented in the Delaware correctional system has as its centerpiece a residential treatment program during work release--the transition between prison and community. An evaluation of this…

We report on survey data collected from 776 final-year student teachers from 11 higher education institutions in October 2004. The purpose of the survey was to find out how many newly qualified teachers were planning to teach abroad and how many were planning to teach in South Africa. Two issues formed the backdrop of the study: teacher migration…

This research was undertaken as part of the National Centre for Vocational Education Research's (NCVER) in-house research program. The report focuses on individuals who, together with industry, are at the centre of vocational education and training (VET). What is novel about the research is that it looks further than skills and workforce outcomes…

This paper examines the contribution of parents' education and children's gender on parental expectations of their children's future education and the role of parental perceptions of their child's competencies in the formation of their expectations. A group of university and vocationally educated parents (N = 418) were asked to estimate the…

If personal computers (PCs) are used to facilitate learning, then a home computer might be considered a potential input in an educational production function. Using data on British youths from the British Household Panel Survey between 1991 and 2001, this paper explores the link between ownership of a home computer at ages 15 and 17 and subsequent…

One theoretical framework which addresses students' conceptions and reasoning processes in mathematics and science education is the intuitive rules theory. According to this theory, students' reasoning is affected by intuitive rules when they solve a wide variety of conceptually non-related mathematical and scientific tasks that share some common…

Our research suggests static and animated graphics can lead to more animated thinking and more correct problem solving in computer-based probability learning. Pilot software modules were developed for graduate online statistics courses and representation research. A study with novice graduate student statisticians compared problem solving in five…

Bernoulli's framework of expected utility serves as a model for various psychological processes, including motivation, moral sense, attitudes, and decision making. To account for evidence at variance with expected utility, the authors generalize the framework of fast and frugal heuristics from inferences to preferences. The priority heuristic…
