In this study, we investigated how secondary students interpret algebraic expressions that contain literal symbols to stand for variables. We hypothesized that the natural number bias (i.e., the tendency to over-rely on knowledge and experiences based on natural numbers) would affect students to think that the literal symbols stand for natural…

Determining the factors that influence implementation of school-based wellbeing and health programs is essential for achieving desired program effects. Using a convergent mixed-methods, multiple informant design, this study considered factors that influence implementation of health programs for ninth grade students and in what ways implementation…

Even the least severe forms of exclusionary discipline are associated with detrimental effects for students that attend schools that overuse them. With a nationally representative longitudinal study of high school students, we utilize propensity score weighting to limit selection bias associated with schools that issue high numbers of in-school…

Purpose: This study aimed to explore students' perspectives and experiences of social and emotional learning (SEL) during physical education high school classes. Method: Using a case study design, focus group and individual interviews were implemented with 42 students. Based on the Collaborative for Academic, Social, and Emotional Learning's SEL…

Executive function (EF) has rarely been considered for adolescents' daily school outcomes or in conjunction with ethnic/racial discrimination. Using 2-week, daily data from 137 ethnic/racial minority adolescents (M[subscript age] = 14.56; 53% female; 56% Black, 19% Latinx, 7% Asian, 7% Native, 12% other [e.g., multiracial]) in the Midwest United…

This study examined the effects of Reading Intervention for Adolescents (RIA) and a mentoring intervention (MI) implemented for 1 year with ninth-grade English learners (ELs) with reading difficulties. Eligible students enrolled at three urban high schools were randomly assigned to the RIA (n = 142), MI (n = 163), RIA and MI (n = 164), or…

Youth-led participatory action research (YPAR) has been documented to increase youth's social, emotional, and cognitive outcomes, foster critical thinking and academic success, and encourage civic participation. YPAR allows for young to develop their voices, direct their own learning and act as change agents as they take steps to influence their…

This work looks at how the infrastructure or conventions of practice and social arrangements govern local classroom literacy practices and how marginalized students resist the infrastructure and expose institutional change-making possibilities. Drawing from a longitudinal study, we analyzed five days of lessons that constituted a project in order…

This study investigated how newcomer emergent bilinguals made meaning in two 9th-grade biology classrooms. Methods relevant to naturalistic inquiry were used to collect and analyze data. Findings indicate that newcomers bridged aspects of personal experiences with social competencies valued in classrooms through using heritage languages, engaging…

The present study examined relations between concern for mianzi, or the social perception of one's prestige and standing in the group, and adjustment in Chinese adolescents. Participants were seventh- and ninth-grade students in rural and urban regions of China (n = 794, M[subscript age] = 14 years). Data were obtained from multiple sources…

Science education reform efforts have called for teaching science to all students, yet the "Science for All" mantra has remained merely rhetoric. Given that multilingual learners continue to face inequities more broadly in the education system and in science, technology, engineering, and mathematics (STEM) subjects in particular, there…

Past research suggests that a sense of belonging to a community is developmentally important for adolescents and affects their engagement in school, especially during the transition to high school. However, little research examines the teaching practices that simultaneously foster classroom belonging and behavioral engagement to create a classroom…

Inspired by a "whole child" framing, the current study takes a "whole classroom" perspective to consider classroom practice. Study aims included: (1) presenting a systematic video-based observational coding strategy to concurrently consider practice domains that have implications for learning--cognitive instruction, classroom…

Mathematical modeling is a challenging and creative process. If one considers only interim or final solutions to modeling problems or interviews modelers afterward, often only their "explicit" models are accessible -- those expressed in work products or evinced in verbal and written reflections. The inner world of tacit knowledge and its…

The COVID-19 pandemic profoundly impacted the methods of instruction for K12 and higher education institutions around the world. Schools and families were challenged to adapt to online-based modes of instruction with minimal preparation. This study examined the importance of the learning environment and commitment to assignments as predictors of…
