La parole au travail a-t-elle un genre ? Dialogues hôtesse de l’air/steward en résolution de problème

Few studies have investigated the way conversational work is divided between men and women in work or problem-solving contexts. This study analyzed dialogues in the workplace between 13 pairs of male and female flight attendants asked to solve a problem adapted from the Wason task. Most previous work suggests that men speak more, interrupt more, and show a greater propensity to put forward a solution. Conversely, women’s speech acts tend to be mainly of an acquiescent or questioning type. Only the hypotheses concerning interruptions, acquiescence and putting forward a solution were confirmed.     

The Effect of Social Networks on the Quality of Political Thinking

In this article we investigate the effect of social networks on the quality of political thinking. First, the article introduces new social network concepts into the literature and develops the corresponding measures. Second, the article explores the quality of political thinking as a concept and develops its measures based on the volume and the causality of thoughts, and their integrative complexity. We make use of a survey to collect information on social networks and the experimental manipulation controls for the effect of policy frames. Our findings consistently show the significant negative impact of cohesive social networks on the quality of policy‐relevant thinking. We conclude that close‐knit social networks could create “social bubbles” that would limit how one communicates with others and reasons about politics.

Hub‐and‐Spoke Student Blogging and Advantages for Classroom Discussion

This essay argues for a particular form of student blogging as a powerful tool for generating and sustaining student engagement and conversation. After a brief discussion of pedagogical principles, “hub‐and‐spoke” blogging is presented as a means to facilitate a more student and discussion‐centered classroom. Based upon recent research and the author's experience, blogging is shown to have a significant impact on both student and instructor preparation for class and to positively shape instructional time.     

Question Design Affects Students' Sense-Making on Mathematics Word Problems

Mathematics word problems provide students with an opportunity to apply what they are learning in their mathematics classes to the world around them. However, students often neglect their knowledge of the world and provide nonsensical responses (e.g., they may answer that a school needs 12.5 buses for a field trip). This study examined if the question design of word problems affects students' mindset in ways that affect subsequent sense-making. The hypothesis was that rewriting standard word problems to introduce inherent uncertainty about the result would be beneficial to student performance and sense-making because it requires students to reason explicitly about the context described in the problem. Middle school students (N = 229) were randomly assigned to one of three conditions. In the standard textbook condition, students solved a set of six word problems taken from current textbooks. In the modified yes/no condition, students solved the same six problems rewritten so the solution helped answer a “yes” or “no” question. In the disfluency control condition, students solved the standard problems each rewritten in a variety of fonts to make them look unusual. After solving the six problems in their assigned condition, all students solved the same three “problematic” problems designed to assess sense-making. Contrary to predictions, results showed that students in the modified yes/no condition solved the fewest problems correctly in their assigned condition problem set. However, consistent with predictions, they subsequently demonstrated more sense-making on the three problematic problems. Results suggest that standard textbook word problems may be able to be rewritten in ways that mitigate a “senseless” mindset.     

Follow Your Heart: Could Psychophysiology Be Associated with Political Discussion Network Homogeneity?

Most Americans are sorted into social networks that are largely politically homogeneous. A large body of political science research has explored the behavioral implications of being embedded in a politically homogeneous or heterogeneous network, but substantially less attention has been given to explaining why some people find themselves in politically homogeneous or heterogeneous social networks. In this article, we explore the psychological and physiological underpinnings of political network homogeneity. We use social network data from an original survey of 129 undergraduates paired with lab experimental evidence that measures individuals' physiological reactivity to an anticipated political discussion. Using our original survey and a separate nationally representative survey, we find suggestive evidence that individuals who are more socially anxious are more likely to share partisanship with their social network ties. Moreover, we find that individuals who experienced a greater increase in heart rate when anticipating a political discussion were more likely to be in homogeneous discussion networks, but we do not find a relationship between electrodermal activity and network homogeneity. Aversion to psychological and physiological discomfort induced by political discussions could contribute to social polarization in the American public.
