Research about modeling emphasizes the importance of heterogeneity in science learning. At the same time, a growing body of scholarship seeks curricular pathways for epistemic and representational convergence. In response to this tension, we propose two constructs: heterogeneity-seeking curricula and commitments. Heterogeneity-seeking curricula…

The Food and Health subject is a mandatory subject in primary and lower secondary schools in Norway and has many similarities to the internationally known subject Home Economics. This study aimed to examine how learning activities are structured in Food and Health education, both from the teacher's and the student's perspective. Momentary time…

This study evaluated the relationship among use defending behaviors, gender, and self-esteem among students trained in a brief, bystander bullying intervention (N = 93). Students were taught four specific strategies to use to defend targets of bullying. We used hierarchical regression analyses to test a moderator model in which we hypothesized…

This paper introduces the LIDO, or the Low-Inference Discourse Observation tool, that captures discourse moves produced by students and teachers in whole-classroom discussions. Coding methods are described, followed by analyses that explore validity of the LIDO through correlations among LIDO-coded discourse moves and between LIDO scores and…

We investigated (1) grade differences in perceived stigma-based peer victimization (SBPV); (2) differences in perceived student and teacher/staff defending against types of SBPV; and (3) whether defending against SBPV affected student subjective wellbeing (SSWB) via anti-victimization school climate perceptions. Participants were 1124 US…

We examined the effect of multiple school-related, resilience-promotive factors against exposure to violence (ETV) at school among an urban sample of 6th-grade students (n = 441, 57% female, mean age = 11.81), 90% identify as students of color. Using multilevel mixed-effects linear models, we analyzed two waves of data (baseline and 4-month…

The study investigated the longitudinal relations between students' roles in bullying (i.e., bullying, defending, and victimization) and social status within the class. Moreover, we tested the hypothesis that students' perception of their own status may mediate these relations. A sample of 432 early adolescents completed peer nominations for…

In science classrooms, technology affordance varies depending on device-student ratios (DSR) and the ways virtual manipulatives on mobile devices are used. Additionally, external scripts (ES) are widely used to promote effective group interaction in collaborative learning. Therefore, this research explored the influence of DSR and ES on…

This qualitative semi-structured interview study investigated how the opportunity to learn with productive struggle emerges in a teacher's beliefs, anticipation, planning, teaching, and response to struggle in learning mathematics. In this study, the experiences of student struggle in the teaching and learning of fractions was investigated through…

Due to technological advancements, robotics is findings its way into the classroom. However, workload for teachers is high, and teachers sometimes lack the knowledge to implement robotics education. A key factor of robotics education is peer learning, and having students (near-)peers teach them robotics could diminish workload. Therefore, this…

Role diversification, the different roles participants adopt within collaborative or inquiry-based teaching and learning environments, is insufficiently understood. We observed two inquiry classroom groups, two teachers and eight students, in weekly visits over three months. Qualitative analysis of audiorecorded interactions, interviews, journals,…

The article explores 5th and 6th grade pupils' reflections on why pupils may refrain from intervening in bullying, despite understanding that bullying is wrong. The findings are based on focus group interviews conducted with 74 Swedish school pupils, who were asked for their perspectives on the various participant roles depicted in a bullying…

This study explores the association between school-level poverty rates and young peoples' perceptions of student empowerment, drawing on survey and administrative data from a large urban district. Participants included 29,318 diverse youth in grades 6-12 from 211 schools. We used multilevel linear regression models to estimate the relationships…

To date, little has been known about teachers' success in bullying interventions. Thus, the present study analyzes how successfully teachers intervene in real bullying situations, based on an analysis of 1,996 reports by German students aged between 12 and 15 (49.2% female) from 24 schools. Predictors of success included intervention strategy…

We evaluated a brief, bystander bullying intervention (STAC) adapted for ethnically blended, low-income middle schools. We examined changes in bullying victimization and bias-based bullying victimization among a sample of sixth-grade students using a mixed factorial design. Students reported a significant decrease in bullying victimization and…
