Mining Mathematics in Textbook Lessons

In this paper, we propose an analytic tool for describing the mathematics made available to learn in a ‘textbook lesson’. The tool is an adaptation of the Mathematics Discourse in Instruction (MDI) analytic tool that we developed to analyze what is made available to learn in teachers’ lessons. Our motivation to adapt the use of the MDI analytic framework to textbooks is to test the relative robustness of the framework in moving across different pedagogic texts (e.g. video of a lesson, a textbook lesson). Our initial findings suggest it has applicability across pedagogic texts, thus opening possibilities for using a common framework and language in research and in professional development activities involving the written and enacted curricula.     

Cross-lagged relationships among leisure-time exercise and perceived stress in blue-collar workers

Blue-collar workers (N = 203) from a large food-processing plant in the southwestern U.S. completed measures of perceived stress and leisure-time exercise at an initial test session in addition to a 2-month follow-up session. Mean age of the sample participants equaled 43.61 (SD = 9.79), and 69.5% of the sample were male, 71.4% were Caucasian, and 74.9% were married/cohabitating. Structural equation modeling was employed to examine the cross-lagged relationships between perceived stress and leisure-time exercise at these time points, controlling for gender, marital status, age, and yearly household income. Results indicated that a model with a path from perceptions of Time 1 stress to Time 2 exercise frequency was most parsimonious and provided acceptable model fit, suggesting that perceptions of stress are related to reductions in exercise participation in this population. However, there was little support for a relationship between Time 1 exercise participation and Time 2 perceived stress.     

Building a space to dream: Supporting indigenous children's survivance through community-engaged social and emotional learning

Indigenous communities practice survivance and challenge social and political systems to support their children's identity and well-being. Grounded in transformative social-emotional learning (SEL) and tribal critical race theory, this 3-year community-based participatory research study (2019–2021) examined how a SEL program co-created with an Indigenous community in Flathead Nation in Montana supports anti-racism and anti-colonialism among Indigenous children. Critical reflexivity and thematic analyses of Community Advisory Board meetings and journals written by 60 students (M_age = 10.3, SD = 1.45; 47% girls; 60% Native American) during the SEL program revealed themes on Indigenous identity, belonging, wellness, and colonialism. These results shed light on challenging the racist and colonial roots of education to support Indigenous children's survivance and social-emotional well-being.

Teachers' Use of Approval and Disapproval in the Classroom

A review and analysis of the research literature on teachers' classroom use of approval/praise and disapproval/reprimand is provided in an attempt to determine the extent to which teachers typically employ praise in their classroom teaching. There is a considerable degree of agreement across the studies reviewed, carried out in the United States, Canada, the United Kingdom, Australia, New Zealand, Hong Kong and St Helena, regarding the ways in which teachers typically deploy approval and disapproval, with some interesting variations. There is little evidence to suggest that teachers, universally, systematically deploy contingent praise as positive reinforcement in spite of the considerable literature testifying to its effectiveness. In particular, praise for appropriate classroom social behaviour is only rarely observed.     

Perceived sibling use of functional communication skills

The purpose of this investigation was to examine the perceived sibling use of functional communication skills (Burleson & Samter, 1990). Participants were 138 undergraduate students enrolled at a small southern university. Three significant findings were uncovered. First, with the exception of referential skill, no significant differences in perceived use of functional communication skills emerged across age groups of siblings. Second, affectively‐oriented functional communication skills were perceived to be used more frequently than nonaffectively‐oriented skills by siblings. Third, female siblings were perceived to use comforting, ego support, and conflict management skills more so than male siblings.
