Embodying Care: Igniting a Critical Turn in a Teacher Educator’s Relational Practice

When a cultural disconnect became antagonistic between me and my students of color, I found myself at a crossroads as a White teacher educator: use coercion and force students to follow my directions, or care and base my responses on students’ needs. I chose the latter. Findings suggest that this choice benefitted the class and changed how I see myself as a teacher educator. The construct of embodied care helps describe the turn in my relational teacher educator practice from caring intentions that were dyadic in nature to caring that uses relational means for social justice ends. Data points include field notes, analytic journal entries, email communication, course materials, student interviews, and course evaluations. This self-study research contributes to the literature on caring teaching by suggesting that, in racially and culturally diverse classrooms, caring habits can help teacher educators from dominant groups gain critical self-awareness.     

A Qualitative Exploration of Romantic Partners’ Motives for and Content of Communication with Friends Following Negative Relational Events

The purpose of this study was to explore young adults’ motives for and content of extradyadic interactions with friends following a negative relational event in a romantic relationship. Focus group discussions with young adults revealed the following partner motives: improving affect, managing uncertainty, obtaining clarity, and entertainment. In turn, friends were motivated by issues of honesty, friendship quality, and a desire to protect or comfort their friend. Both partners and friends discussed the use of a variety of negative, neutral, and positive message content. Results provide an exploratory look at extradyadic interactions that may have important implications for relationship functioning.

Taking the relational structure of fractions seriously: Relational reasoning predicts fraction knowledge in elementary school children

Understanding and using symbolic fractions in mathematics is critical for access to advanced STEM concepts. However, children and adults consistently struggle with fractions. Here, we take a novel perspective on symbolic fractions, considering them within the framework of relational structures in cognitive psychology, such as those studied in analogy research. We tested the hypothesis that relational reasoning ability is important for reasoning about fractions by examining the relation between scores on a domain-general test of relational reasoning (TORR Jr.) and a test of fraction knowledge consisting of various types of fraction problems in 194 s grade and 145 fifth grade students. We found that relational reasoning was a significant predictor of fractions knowledge, even when controlling for non-verbal IQ and fractions magnitude processing for both grades. The effects of relational reasoning also remained significant when controlling for overall mathematics knowledge and skill for second graders but was attenuated for fifth graders. These findings suggest that this important subdomain of mathematical cognition is integrally tied to relational reasoning and opens the possibility that instruction targeting relational reasoning may prove to be a viable avenue for improving children’s fractions skills.
