Using Multidimensional Scaling and Unfolding to Explore Teacher Perceptual Biases for Selected Special Education Referral Categories

Multidimensional scaling (POLYCON) and unfolding (PREFMAP) algorithms developed by Young (24) and Carroll (3), respectively, were used to explore teacher perceptions of special education labels (e.g., emotional disturbance) in terms of a reference set of 28 student behaviors (e.g., withdrawn, short attention span) across two context variables: student gender and student ethnicity. The resulting two-dimensional scaling solution revealed teacher perceptual distinctions between student acting-out and passive behaviors, and between student intellectual impairment and specific behavior problems. In addition, scaling analyses also suggested teacher perceptual biases that required both males and minority (i.e., black) students to behave more extremely before being seen by teachers as having either learning or emotional problems.     

Emotional arousal of beginning physics teachers during extended experimental investigations

Teachers often have difficulty implementing inquiry‐based activities, leading to the arousal of negative emotions. In this multicase study of beginning physics teachers in Australia, we were interested in the extent to which their expectations were realized and how their classroom experiences while implementing extended experimental investigations (EEIs) produced emotional states that mediated their teaching practices. Against rhetoric of fear expressed by their senior colleagues, three of the four teachers were surprised by the positive outcomes from their supervision of EEIs for the first time. Two of these teachers experienced high intensity positive emotions in response to their students' success. When student actions/outcomes did not meet their teachers' expectations, frustration, anger, and disappointment were experienced by the teachers, as predicted by a sociological theory of human emotions (Turner, J. H. (2007). Human emotions: A sociological theory. London, England: Routledge). Over the course of the EEI projects, the teachers' practices changed along with their emotional states and their students' achievements. We account for similarities and differences in the teachers' emotional experiences in terms of context, prior experience, and expectations. The findings from this study provide insights into effective supervision practices that can be used to inform new and experienced teachers alike. © 2012 Wiley Periodicals, Inc.

The Populist Chameleon: The People's Party,Huey Long,George Wallace,and the Populist Argumentative Frame

This essay argues that a sustained form can be located in the complicated history of populist rhetoric. Despite its chameleonic qualities, the advancement of populism is constituted by alterations in the focus and content, not the structure, of populist activism. This structure, or what I term its argumentative frame, positions a virtuous people against a powerful enemy and expresses disdain toward traditional forms of democratic deliberation and republican representation. I trace these themes through the rhetoric of the People's Party, Huey Long, and George Wallace. I conclude by analyzing the link between populism's persistence in U.S. history and the nation's Founding.     

A Twins study of communicative adaptability: Heritability of individual differences

Recently, a model of communication theory and research has appeared in the literature within which stable individual differences in communication behavior represent individual differences in activation thresholds of neurobiological systems. The neurobiological systems thought to underly communication traits and behavior are assumed to be primarily due to genetic inheritance. As such, the model assigns a limited role to adaptability in social situations, instead positing communication adaptability as an inherited trait. In the present study, heritability estimates for the dimensions of communicative adaptability were derived from correlations based on identical and fraternal twins’ responses to a multidimensional communicative adaptability measure. Results indicated that social composure was 88% heritable, wit was 90% heritable, social confirmation was 37% heritable, articulation ability, and appropriate disclosure were 0% heritable. Theoretical implications are discussed.     

Moral Education at Religious Research Universities: Exploring Faculty Attitudes

This article presents the results and an analysis of 1,728 survey responses from faculty at four top tier religious research universities regarding their support for moral and civic education. The results demonstrate that a majority of faculty members at these schools supported both the general goals of moral and civic education and specific suggestions for integrating moral and civic education into the curriculum. Nonetheless, three major concerns emerged about its actual implementation into the curriculum.     

A Framework for Designing Scaffolds That Improve Motivation and Cognition

A problematic, yet common, assumption among educational researchers is that when teachers provide authentic, problem-based experiences, students will automatically be engaged. Evidence indicates that this is often not the case. In this article, we discuss (a) problems with ignoring motivation in the design of learning environments, (b) problem-based learning and scaffolding as one way to help, (c) how scaffolding has strayed from what was originally equal parts motivational and cognitive support, and (d) a conceptual framework for the design of scaffolds that can enhance motivation as well as cognitive outcomes. We propose guidelines for the design of computer-based scaffolds to promote motivation and engagement while students are solving authentic problems. Remaining questions and suggestions for future research are then discussed.     

Responses to refusals of requests: Face threat and persistence,persuasion and forgiving statements

Wilson et al.'s (1998) revision of politeness theory has been applied to requesting, refusing and relational development, finding that different types of face threat are present in an interaction depending on the interaction goals. This investigation seeks to extend Wilson et al.'s (1998) work by determining how threats to a speaker's and hearer's face needs influence a requester's desire to persist and use of persuasion and forgiving statements after refusal. Results indicate that refusals creating greater threat to the positive and negative face needs of requesters yield greater desire to persist and use of persuasion statements. Specific face threats did not appear to be related to use of forgiving statements.
