Shows how to extend the inferential test of B. Shipley (2000), which is applicable to recursive path models without correlated errors, to a class of recursive path models that includes correlated errors. Discusses when the extended model is and is not superior to classical structural equation modeling. (SLD)

Generalized Structured Component Analysis (GSCA) was recently introduced by Hwang and Takane (2004) as a component-based approach to path analysis with latent variables. The parameters of GSCA are estimated by pooling data across respondents under the implicit assumption that they all come from a single, homogenous group. However, as has been…

In China's current educational fiscal decision making, problems are as follows: no law to trust or not abiding by available laws, absence of equity and efficiency, as well as the standardization of decision-making procedures. It is necessary to set up effective fiscal decision-making mechanism in education and rationally devise reliable paths.

Causal modeling is examined for its heuristic value by describing its use in an introductory course in educational evaluation, and presenting a student-developed model. Subjects included students in either master's programs in statistics or doctoral programs in administration and curriculum. Before preparing an evaluation plan and path analysis,…

A rationale for the difference in the periodic trends in the ionization energy of the transition-metal elements versus the main-group elements is presented. The difference is that in the transition-metal elements, the electrons enter an inner-shell electron orbital, while in the main-group elements, the electrons enter an outer-shell electron…

This article is an attempt to critique some of the limitations of dominant school reform discourses in education, drawing upon the work of Michel Foucault, Michael Apple, Maxine Greene, and Dennis Carlson, in addition to writers in the emerging field of what might be called "eco-progressivism." The intersections between ecology and education can…

The dangers of overlooking time-honored cautions in the making causal interpretations of data analyses from correlational studies when using highly sophisticated computer programs and their associated techniques are discussed. (JKS)

Describes a study of students in grades three, four, and five that tried an educational application derived from the social constructivism view based on theories of Vygotsky and Piaget to improve cognitive development in a heterogeneous class. Path analysis showed that complex learning techniques are related to cognitive development. (Author/LRW)

Multicollinearity is a well-known general problem, but it also seriously threatens valid interpretations in structural equation models. Illustrating this problem, J. Pietsch, R. Walker, and E. Chapman (2003) found paths leading to achievement were apparently much larger for self-efficacy (.55) than self-concept (-.05), suggesting--erroneously, as…

This work extends the theory of the fixed charge transportation problem (FCTP), currently based mostly on a forty-year-old publication by Hirsch and Danzig. This paper presents novel properties that need to be considered by those using existing, or those developing new methods for optimizing FCTP. It also defines the problem in an easier way,…

This report describes the initial employment and educational paths pursued by physics and astronomy degree recipients at the bachelor's, master's, and PhD levels for the classes of 2002-03 and 2003-04. The report includes starting salaries, primary work activities, ratings of professional challenge and other aspects of initial employment. The…

This article generalizes linear path analysis (PA) and simultaneous equations models (SiEM) to deal with mixed responses of different types in a recursive or triangular system. An efficient instrumental variable (IV) method for estimating the structural coefficients of a 2-equation partially recursive generalized path analysis (GPA) model and…

The generalizability of K. M. Cramer's (1999) help-seeking model was examined for Asian and Asian American college students. The construct of acculturation was then added to Cramer's model to determine if it would improve the model fit. Asian and Asian American (n=202) students completed help-seeking measures and behavioral and value-based…

Examined were several theoretically important relations among motivational characteristics of students that are malleable, or changeable with intervention. The motivational construct identification with academics, which includes perceptions of belonging and valuing within an academic context, was investigated along with intrinsic/extrinsic…

LISREL-type structural equation modeling is a powerful statistical technique that seems appropriate for social science variables which are complex and difficult to measure. The literature on the specification, estimation, and testing of such models is voluminous. The greatest proportion of this literature, however, focuses on the technical aspects…
