A Student Guide for Interpreting Case Material

Abstract

The use of peers in the evaluation of teaching is part of a larger trend in postsecondary education toward a more systematic assessment of classroom performance. Many scholars believe that certain aspects of teaching can be assessed only by classroom observation. This study examines the use that peer reviewers make of teaching products, especially peer observation reports, during the promotion and tenure review process. Results indicate that peer observation reports are seen as an important component in evaluating teaching effectiveness, though perhaps not the best indicator of effective teaching. Despite flaws in peer observation instruments, the results from classroom observation are seen as valid and are used in deliberations about faculty teaching performance.     

Procedures to Follow if a Law Enforcement Official Asks for Patron Information: A Checklist for Access Services Student Employees

ABSTRACT

Since the U.S.A. PATRIOT Act was signed into law in October, 2001, library administrators have become increasingly concerned that staff–especially student employees–continue to protect the confidentiality of patron records. Administrators have also become increasingly concerned that when law enforcement officials provide paperwork giving them legal access to patron records, staff take steps both to divulge no more information than is necessary and to protect the institution from liability. In response to these concerns, the University of Colorado, Boulder, created an easy-to-understand and easy-to-use document for its public services student employees. This article describes the process by which that document was created, how it was introduced to staff and student employees, and what additional steps are planned for the future. Finally, the document itself is included as a possible model for other institutions that may wish to create procedural guidelines for student employees.     

Improving the Root Mean Square Error of Approximation for Nonnormal Conditions in Structural Equation Modeling

In this study, the authors investigated incorporating adjusted model fit information into the root mean square error of approximation (RMSEA) fit index. Through Monte Carlo simulation, the usefulness of this adjusted index was evaluated for assessing model adequacy in structural equation modeling when the multivariate normality assumption underlying maximum likelihood estimation is violated. Adjustment to the RMSEA was considered in 2 forms: a rescaling adjustment via the Satorra-Bentler rescaled goodness-of-fit statistic and a bootstrap adjustment via the Bollen and Stine adjusted model p value. Both properly specified and misspecifed models were examined. The adjusted RMSEA was evaluated in terms of the average index value across study conditions and with respect to model rejection rates under tests of exact fit, close fit, and not-close fit.     

Attribution‐based strategies for initiating and terminating friendships

Research in attribution theory has almost exclusively focused on the perception process to the neglect of studying how communicators incorporate attribution‐based information in their message behavior. This study derived a typology of attribution‐based strategies from Kelley's attribution cube and Jones' ingratiation tactics to assess respondent strategies for initiating and for terminating same‐sex friendships. Respondents were 191 persons drawn from fifth grade, high school, college, and post‐college groups. Results of the study included: 1) distinctiveness information was disproportionately employed in the strategy repertoires to the neglect of consistency‐based and consensus‐based information; 2) respondents had greater variety in types of strategies for their initiation repertoires as opposed to their termination repertoires; 3) repertoire variety for both initiation and termination increased from childhood through adolescence.     

Questions of (re)production and legitimation: A second screening of three films on teacher-student relations

This study considers three Hollywood films that take, as their subject, a teacher-hero confronted with a 'problem' group of students and, as their narrative, the rehabilitation of these students and the resolution of their problems. Employing a Bourdieuian analysis, we attempt a second screening of these films on two levels: first, by stepping inside these celluloid classrooms, so to speak, and narrating a different text, one that is spoken from the position of students and which challenges each film's portrayal of good people achieving fine things; and secondly, by screening for gaps in their accounts of schooling, exposing their limited frames of reference and their legitimacy to speak on behalf of authentic classrooms. The first of these projects is undertaken as a way of challenging teachers and interested others to be wary of uncritical readings of popular images of teaching, whereas the second provides a beginning from which to consider how teachers' pedagogy and school curricula can be informed by a radical democratic view of education - how teachers might embrace the foreign.
