A key feature of the analysis of three-way arrays by Candecomp/Parafac is the essential uniqueness of the trilinear decomposition. We examine the uniqueness of the Candecomp/Parafac and Indscal decompositions. In the latter, the array to be decomposed has symmetric slices. We consider the case where two component matrices are randomly sampled…

The purpose of this study was to investigate and compare the performance of a stepwise variable selection algorithm to traditional exploratory factor analysis. The Monte Carlo study included six factors in the design; the number of common factors; the number of variables explained by the common factors; the magnitude of factor loadings; the number…

In many instances it is reasonable to assume that the population covariance matrix has positive elements. This assumption implies for the single factor analysis model that the loadings and regression weights for best linear factor prediction are positive. For the multiple factor analysis model where each variable loads on a single factor and a…

An alternative formulation of the multigroup common factor model with minimal uniqueness constraints is considered. This alternative formulation is based on a simple identification constraint that is related to the standard maximum likelihood constraint used in single-group common factor analysis. It is argued that the alternative formulation…

The authors provide generalizations of R. J. Boik's (1993) studentized maximum root (SMR) procedure that allow for simultaneous inference on families of product contrasts including simple effect contrasts and differences among simple effect contrasts in coherent analyses of data from 2-factor fixed-effects designs. Unlike the F-based simultaneous…

The Behavior Checklist, a self-report test procedure, was administered to 42 adults who stutter and 76 who do not in order to investigate the number, frequency of usage, type and nature of the responses that they reportedly employ to cope with the anticipation and/or presence of speech disruption. As a group, the participants who stutter reported…

Purpose: This study developed measures of satisfaction with assisted living from residents' and family members' perspectives. Design and Methods: We collected survey data from 204 residents and 232 family members associated with 11 assisted living facilities. We used confirmatory factor analysis to evaluate the goodness of fit of a priori…

Learning strategies have been increasingly recognized as a useful tool to promote effective learning. In response to the lack of available learning strategies measures for middle school students, this study designed an instrument for these students, assessing behavioral, cognitive, and metacognitive strategies. This instrument, the Middle School…

Studies that examine the impacts of education interventions on key student, teacher, and school outcomes typically collect data on large samples and on many outcomes. In analyzing these data, researchers typically conduct multiple hypothesis tests to address key impact evaluation questions. Tests are conducted to assess intervention effects for…

The main purpose of this study was to investigate the factors that might be associated with students' attitudes towards science. The participants were 1745 students from secondary schools and universities across Australia. The results of factor analysis, descriptive statistics, Tukey's post hoc test and correlation analysis demonstrate that there…

Purpose: In light of the excessively broad conceptions and nonobservable terms generally characterizing discussions of organizational learning, this study explores the notion of organizational learning in schools through the conceptual framework of organizational learning mechanisms (OLM) and develops a measure of OLM at the elementary school…

Recently, several scholars have suggested that academic self-regulation may be particularly important for students participating in online learning. The purpose of the present study was to develop a quantitative self-report measure of perceived task value and self-efficacy for learning within the context of self-paced, online training, and to…

The question whether executive function (EF) deficits in children are associated with conduct problems remains controversial. Although the origins of aggressive behavior are to be found in early childhood, findings from EF studies in preschool children with aggressive behavior are inconsistent. The current study aimed to investigate whether…

The purpose of this research is to provide additional empirical evidence supporting the use of both a multidimensional profile and an overall evaluation of teaching effectiveness as valid indicators of student perceptions of effective classroom instruction. A factor analytic teaching evaluation instrument was used that also included open-ended…

Background: The mixed findings of previous studies on the nature and effects of performance goals have led to a call for re-examination of the dichotomous framework of achievement goal orientation theory. While the call for a revised achievement goal orientation theory has received considerable discussion in Western studies, it is not clear…
