Generalizability and decision studies provide a mathematical framework for quantifying the stability of a given number of measurements. This approach is especially relevant to the task of obtaining a representative measure of communicative behavior in young children and supports an alternative to the debate regarding which type of assessment…

The current nursing shortage has challenged colleges to educate nurses at a faster pace than in previous times. Successful completion of the nursing programs and passing the National Council Licensure Examination for Registered Nurses (NCLEX-RN) exam is important for the students, faculty, and nursing programs. The purpose of this retrospective…

Alternative approaches are discussed for use of e-rater[R] to score the TOEFL iBT[R] Writing test. These approaches involve alternate criteria. In the 1st approach, the predicted variable is the expected rater score of the examinee's 2 essays. In the 2nd approach, the predicted variable is the expected rater score of 2 essay responses by the…

This study investigated the relationships between when a test is administered and the amount of test-taking effort exhibited by examinees. Three time-related variables were investigated: the time of year the test was administered, the day of the week the test event occurred, and the time of day that the test event occurred. Mean effort did not…

A common problem in predictive validity studies in the educational and psychological fields, e.g. in educational and employment selection, is restriction in range of the predictor variables. There are several methods for correcting correlations for restriction of range. The aim of this paper was to examine the usefulness of two approaches to…

Theories that posit multiplicative relationships between variables are common in psychology. A. G. Greenwald et al. recently presented a theory that explicated relationships between group identification, group attitudes, and self-esteem. Their theory posits a multiplicative relationship between concepts when predicting a criterion variable.…

Value-added models in education research allow researchers to explore how a wide variety of policies and measured school inputs affect the academic performance of students. Researchers typically quantify the impacts of such interventions in terms of "effect sizes", i.e., the estimated effect of a one standard deviation change in the…

The general linear model was described, and the influence that measurement errors have on model parameters was discussed. In particular, the assumptions of classical true-score theory were used to develop algebraic relationships between the squared multiple correlations coefficient and the regression coefficients in the infallible and fallible…

Purpose: The paper deals with the study of students' computer literacy one of the purposes being demonstration the impact of the cognitive and non-cognitive personality traits (attention, verbal and non-verbal intelligence, emotional-motivational relationship with computer, learning strategies, etc.) on the quality of computer literacy.…

The relation between Bayley Scale and Stanford-Binet measures in preschool and scholastic achievement at pre-adolescence is examined in the context of an early age intervention. The program sought to normalize the socio-cognitive development of disadvantaged 2-year-olds directly and through a training program for mothers. The follow-up includes a…
