Two negatives don't always make a positive: Exploring how limitations in teacher knowledge and the curriculum contribute to instructional quality

This paper examines the contribution of mathematical knowledge for teaching (MKT) and curriculum materials to the implementation of lessons on integer subtraction. In particular, it investigates the instruction of three teachers with differing MKT levels using two editions of the same set of curriculum materials that provided different levels of support. This variation in MKT level and curriculum support facilitated exploring the distinct and joint contribution of MKT and the curriculum materials to instructional quality. The analyses suggest that MKT relates positively to teachers' use of representations, provision of explanations, precision in language and notation, and ability to capitalize on student contributions and move the mathematics along in a goal-directed manner. Curriculum materials set the stage for attending to the meaning of integer subtraction and appeared to support teachers' use of representations, provision of explanations, and precision in language and notation. More critically, the findings suggest that less educative curriculum materials, coupled with low levels of MKT, can lead to problematic instruction. In contrast, educative materials can help low-MKT teachers provide adequate instruction, while higher MKT levels seem to enable teachers to compensate for curriculum limitations.     

Integrating Education on Addressing Health Disparities into the Graduate Social Work Curriculum

The purpose of this article is to propose an elective social work course as a means of better preparing social workers entering practice in healthcare to meet the challenges of promoting health and reducing health disparities in minority and underserved communities. Course offerings specifically targeting health or medical social work training vary widely. The additional training provided at places of employment and through continuing education after the master's degree is often inadequate for competently addressing the issues clinicians face in practice.     

Contractualism,Committalism, and Covenantalism: A Worldview Dimensional Analysis of Human Relating

Throughout the literature much of the research on political campaign debates has focused on presidential debates and has largely ignored non‐presidential debates, particularly those featuring candidates competing in mixed‐gender races. The purpose of this study is to draw attention to these non‐presidential debates and particularly those in which gender may play a pivotal role. Through our analysis of four debates—two gubernatorial and two U.S. Senate debates—we advance the notion of debatestyle as a useful analytic scheme to examine the verbal content of female and male candidate debate dialogue. While few differences in female and male debatestyles ultimately emerged, results of the current study indicate that female and male political candidates, when engaged in debate, adopt a strategy of gendered adaptiveness that offers important contributions to both research on political debates as well as research on gender and politics.     

Getting the actor to act

The hypothesis that a self‐contradictory communication is less persuasive than a non‐contradictory one was tested. The data supported the hypothesis only for those subjects who perceived the contradiction; neither open and closed‐mindedness nor initial attitude toward the policy advocated in the communication accurately distinguished the perceivers of the contradiction from the non‐perceivers.     

Service Learning as a Pedagogy of Whiteness

In this article we employ whiteness as a conceptual framework to contextualize how faculty develop and implement, and consequently how students experience, service learning. A vignette that illustrates the pervasiveness of whiteness in service learning is followed by an analysis that details how whiteness frames the teaching and learning in this service learning experience. Through this example and analysis, we seek to increase instructors’ capacity and confidence to interrupt the patterns and privileges of whiteness that too often are normalized in service learning.     

Crisis negotiations: A Preliminary investigation of facework in naturalistic conflict discourse

This article views crisis negotiations from an interaction goal perspective, with facework constituting a significant and heretofore unexplored dimension of interaction. We present a three‐dimensional model of facework used in coding perpetrator and negotiator discourse for face behaviors within three authentic negotiation interactions. Results indicate that Restore Other's Face and Restore Self's Face were the two predominant facework behaviors. While negotiators were the primary users of Restore Other's Face acts, perpetrators used mostly Restore Self's Face behaviors. No Attack Other's Face acts were observed. However, of five Attack Self's Face behaviors enacted, four occurred in a negotiation which ended in the suicide of the perpetrator. Lag sequential analysis revealed a general cycle of perpetrator use of Restore Self's Face and negotiator use of Restore Other's Face. Implications of these findings for future research and for training crisis negotiators are discussed.     

Does grade inflation affect the reliability of grades?

Two studies were conducted to examine the effect of grade inflation on the piling up of grades in fewer grade categories and on the reliability of grade point averages (GPAs). In all comparisons, grades were more bunched after grade inflation, which in turn, was associated with only slight, nonsignificant decreases in GPA reliability. As expected, grades were more bunched when the traditional 5-point letter scale was used than when plus and minus grades were also allowed. In the latter case as well, grade inflation seemed to have had very little effect on the reliability of GPAs. GPA reliability began to suffer, however, for graduate programs in which almost all grades were placed into just two categories, A and B.     

Threading mathematics through symbols,sketches, software,silicon, and wood: Teachers produce and maintain cohesion to support STEM integration

ABSTRACT

This classroom-based investigation sought to document how, in real time, STEM teachers and students attempt to locate the invariant mathematical relations that are threaded through the range of activities and representations in these classes, and how highlighting this common thread influences student participation and learning. The authors conducted multimodal discourse analyses of teacher–student interactions during multiday observations in 3 urban high school STEM classes. The focal lessons were in electrical engineering and mechanical engineering (within Project Lead the Way), and precollege geometry. Across 3 cases, teachers and students actively built and maintained cohesion of invariant mathematical relations across activities and representations. Pre- and postlesson interviews revealed that teachers intentionally managed cohesion to provide the continuity across the curricular activities that teachers believed would promote student understanding. The findings contribute to ways of fostering STEM integration and ways of grounding abstractions to promote meaning making and transfer.     

Time limits in testing: An analysis of eye movements and visual attention in spatial problem solving

Individuals with an aptitude for interpreting spatial information (high mental rotation ability: HMRA) typically master anatomy with more ease, and more quickly, than those with low mental rotation ability (LMRA). This article explores how visual attention differs with time limits on spatial reasoning tests. Participants were assorted to two groups based on their mental rotation ability scores and their eye movements were collected during these tests. Analysis of salience during testing revealed similarities between MRA groups in untimed conditions but significant differences between the groups in the timed one. Question‐by‐question analyses demonstrate that HMRA individuals were more consistent across the two timing conditions (κ = 0.25), than the LMRA (κ = 0.013). It is clear that the groups respond to time limits differently and their apprehension of images during spatial problem solving differs significantly. Without time restrictions, salience analysis suggests LMRA individuals attended to similar aspects of the images as HMRA and their test scores rose concomitantly. Under timed conditions however, LMRA diverge from HMRA attention patterns, adopting inflexible approaches to visual search and attaining lower test scores. With this in mind, anatomical educators may wish to revisit some evaluations and teaching approaches in their own practice. Although examinations need to evaluate understanding of anatomical relationships, the addition of time limits may induce an unforeseen interaction of spatial reasoning and anatomical knowledge.
