A factor-analytic reinterpretation of the Clark-Trow "educational philosophies"

Each of four principal components analyses (n = 3,944) incorporated student self-ratings (Most accurate to Least accurate) on one of the four Clark-Trow educational philosophies: Vocational, Academic, Collegiate, Nonconformist. The analyses of these 25-variable correlation matrices yielded 2 factors differentially associated with educational philosophy: Sociability versus Independence (replacing Clark-Trow's "Identification with the College") and Liberalism versus Conservatism (replacing Clark-Trow's "Involvement with Ideas"). The Vocational philosophy was associated primarily with Conservatism, the Collegiate with Sociability, and the Nonconformist with Liberalism; the Academic was moderately associated with both Independence and Liberalism.

Higher Educational Impact on Student Objectives: Longitudinal Change in Clark-Trow "Educational Philosophies"

This study explores the impact of higher education on 3,942 arts and sciences students as measured by change in their freshman and senior ratings of four Clark-Trow "educational philosophies": vocational, academic, collegiate, and nonconformist (Clark and Trow, 1966). A repeated measures analysis of variance was applied to each of the four philosophies, controlling for sex, entering year, major, parents' educational background, scholastic aptitude, and academic motivation. As expected from Clark-Trow theory, students showed significant increases in academic and nonconformist philosophies, and decreases in vocational and collegiate philosophies. Relationships between independent variables and freshman-senior change suggested post hoc reinterpretation of the dimensions underlying the Clark-Trow "phenotypes": i. e., from "identification with the college" and "involvement with ideas" to "social interests" and "academic interests" (the latter suggested by Terenzini and Pascarella, 1977).

The Impact of Greek Affiliation on Students’ Educational Objectives: Longitudinal Change in Clark-Trow Educational Philosophies

Change in 4,119 students' freshman to senior ratings of four educational philosophies (vocational, academic, collegiate, and nonconformist) provided four measures of educational impact. Repeated measures analyses of variance compared changes in philosophy as a function of Greek affiliation, controlling for sex, historical era, major, parents' education, scholastic aptitude, and academic motivation. Small but significantly different degrees of change in the collegiate and nonconformist philosophies suggested that Greek affiliation increased social interests and inhibited some forms of intellectual interests. These small differences across all students masked the moderating effect of major. In the nonconformist philosophy, for example, the Greek × major interaction reflected substantial Greek–independent differences among humanities majors, and progressively smaller differences or reversals among social science, physical science, and engineering majors. Possible interpretations of this interaction are offered.

A Simple Visual Demonstration of Phase Diagram Concepts for an Introductory Materials Science Course Using Colored Solvents

A simple and effective demonstration to help students comprehend phase diagrams and understand phase equilibria and transformations is created using common chemical solvents available in the laboratory. Common misconceptions surrounding phase diagram operations, such as components versus phases, reversibility of phase transformations, and the lever rule are addressed. Three different binary liquid mixtures of varying compatibility create contrastive phase equilibrium cases, where colorful dyes selectively dissolved in each of corresponding phases allow for quick and unambiguous perceptions of solubility limit and phase transformations. Direct feedback and test scores from a group of students show evidence of the effectiveness of the visual and active teaching tool.

Knuckling Under? School Superintendents and Accountability-Based Educational Reform

The goal of this article is to explore the various ways that superintendents have responded to accountability-based educational reform efforts such as No Child Left Behind, the factors that have influenced their responses, and the implications of these responses for current and future educational leaders. With respect to the first issue, empirical data from a number of nationai studies (T. E. Glass & Franceschini, 2007; Johnson, Arumi, & Ott, 2006; Johnstone, Dilkkers, & Luedeke, 2009; Stecher et al., 2008) make clear that while there have been a variety of responses from superintendents to accountability-based reform efforts, superintendents have mostly played a supportive role. Examining the situation more fully suggests that the driving factors behind superintendent support for accountability-based educational reform are complex and are often deeply embedded within the "DNA" of the role of superintendent. This article examines the structure of this DNA by looking at the factors that influence superintendents' views of accountability-based educational reform from historical, political, and institutional perspectives. This muitifaceted approach provides new insights into the complex relationship that exists between the structure of the role of superintendent and the agency of the individuals who inhabit that role.

Organic Interfaces; or, How Human Beings Augment Their Digital Devices

It is a central premise of the advertising campaigns for nearly all digital communication devices that buying them augments the user: they give us a larger, better memory; make us more “creative” and “productive”; and/or empower us to access whatever information we desire from wherever we happen to be. This study is about how recent popular cinema represents the failure of these technological devices to inspire the enchantment that they once did and opens the question of what is causing this failure. Using examples from the James Bond films, the essay analyzes the ways in which human users are frequently represented as the media connecting and augmenting digital devices and NOT the reverse. It makes use of the debates about the ways in which our subjectivity is itself a networked phenomenon and the extended mind debate from the philosophy of mind. It will prove (1) that this represents an important counter-narrative to the technophilic optimism about augmentation that pervades contemporary advertising, consumer culture, and educational debates; and (2) that this particular discourse of augmentation is really about technological advances and not advances in human capacity.

Local Impacts of Unconventional Gas Development within Pennsylvania's Marcellus Shale Region: Gauging Boomtown Development through the Perspectives of Educational Administrators

Using survey and interview data gathered from educators and educational administrators, we investigate school and community impacts of unconventional gas extraction within Pennsylvania's Marcellus Shale region. Respondents in areas with high levels of drilling are significantly more likely to perceive the effects of local economic gains, but also report increased inequality, heightened vulnerability of disadvantaged community members, and pronounced strains on local infrastructure. As community stakeholders in positions of local leadership, school leaders in areas experiencing Marcellus Shale natural gas extraction often face multiple decision-making dilemmas. These dilemmas occur in the context of incomplete information and rapid, unpredictable community change involving the emergence of both new opportunities and new insecurities.

Dependence of Positronium Lifetime on Temperature in Porous Materials

A positron and electron can form the bound state called positronium. When positronium is formed in a porous material, its lifetime is based on the electron density of the pore walls, temperature, and pore size according the Rectangular Extenstion to the Tao-Eldrup Model. Positronium Annihilation Lifetime Spectroscopy is an established technique of finding positronium lifetimes. Using this technique, we find positronium lifetimes at various temperatures and compare these to the expectations of the model. We find that the pore size relationship is consistent, but more data must be gathered under different conditions in order to draw conclusions about relationships between lifetime, temperature, and pore size.
