This article describes the ways in which the mathematics department of an urban, ethnically diverse school brought about high and equitable mathematics achievement. The teachers employed heterogeneous grouping and complex instruction, an approach designed to counter status differences in classrooms. As part of this approach teachers encouraged multidimensional classrooms, valued the perspectives of different students, and encouraged students to be responsible for each other. The work of students and teachers at Railside School was equitable partly because students achieved more equitable outcomes on tests, but also because students learned to act in more equitable ways in their classrooms. Students learned to appreciate the contributions of students from different cultural groups, genders, and attainment levels, a behavior termed relational equity. This article describes the teaching practices that enabled the department to bring about such important achievements.

Can positive social contact between members of antagonistic groups reduce prejudice and discrimination? Despite extensive research on social contact, observational studies are difficult to interpret because prejudiced people may select out of contact with out-group members. We overcome this problem by conducting an education-based, randomized field experiment—the Urban Youth Vocational Training program (UYVT)—with 849 randomly sampled Christian and Muslim young men in riot-prone Kaduna, Nigeria. After sixteen weeks of positive intergroup social contact, we find no changes in prejudice, but heterogeneous-class subjects discriminate significantly less against out-group members than subjects in homogeneous classes. We trace this finding to increased discrimination by homogeneous-class subjects compared to non-UYVT study participants, and we highlight potentially negative consequences of in-group social contact. By focusing on skill-building instead of peace messaging, our intervention minimizes reporting bias and offers strong experimental evidence that intergroup social contact can alter behavior in constructive ways, even amid violent conflict.

Metacognition is a critical factor in mathematical problem-solving, particularly in collaborative learning contexts. This study aims to explore how secondary students’ metacognitive processes (planning, monitoring, and evaluating) emerge during collaborative mathematical problem-solving within heterogeneous ability groups. A qualitative case study was conducted with grade VIII students at an Islamic junior secondary school in Indonesia. Twelve students were purposively selected from a class of thirty-three and organized into four heterogeneous groups based on mathematical ability levels (high, medium, and low). Data were collected through mathematics ability tests, collaborative problem-solving tasks involving non-routine linear equations, classroom observations, video recordings, and semi-structured group interviews. Data analysis followed iterative qualitative procedures, including data reduction, data display, and conclusion drawing, focusing on identifying patterns of metacognitive regulation at both individual and group levels. The findings reveal that planning and monitoring were consistently observed across groups, while evaluative metacognition remained underdeveloped and unevenly distributed.

Purpose This paper aims to investigate the relationship between inclusive leadership (IL) and organizational inclusion (OI) in literature and explores the contribution of IL and OI in human resources development (HRD). Design/methodology/approach The systematic literature review was undertaken from peer-reviewed journals. In total, 68 articles were critically analyzed to be included in the review highlighting the relationship between IL and OI. Findings The paper provides insights into leader behaviors that foster IL and how it differs from other styles of leadership. The paper also proposes a theoretical model to show the relationship between IL and OI. Practical implications The study will facilitate creating awareness in practitioners and academicians who think inclusion is mostly concerned with disabled learners, which is misleading. The paper will help the concerned stakeholders to formulate HRD practices to foster an inclusive culture at work. Originality/value The paper explores an area less researched and is among the few review papers investigating through the relationship between IL and OI and how they impact HRD practices in an organizational set-up.

Grouping students according to their abilities and promoting deeper interaction and moderation are key issues in improving computational thinking in collaborative programming. However, the distribution characteristics and evolving pathways of computational thinking in different groups have not been deeply explored. During the course of a twelve-week term, 30 sophomores participated in shared regulation-supported collaborative programming activities. This study employed statistical analysis, lag sequence analysis, and epistemic network analysis to examine the effects of ability grouping on students' behavioral patterns and cognitive networks of computational thinking. The study shows heterogeneous groups predominantly engaged with computational practices and ideas, while within homogeneous groups, high-ability groups concentrated on computational practices and low-ability groups on computational concepts. Analysis of behavior sequences across varying ability groups revealed that heterogeneous groups exhibited significantly more behaviors related to monitoring and evaluation, forming a cyclical correlation, unlike homogeneous groups which did not exhibit reflective collaborative effects. Moreover, in the initial phases of collaborative programming, the structure of the computational thinking network varied markedly across groups of different competencies. However, as group awareness tools were progressively employed, the cognitive network centroids of all groups began to show converging trajectories. These results underscore that both shared regulation strategies and grouping strategies can facilitate the enhancement of computational thinking, offering theoretical insights and practical guidance for the higher education sector.

Most existing studies investigating profiles of anxious and depressive symptoms in adolescent boys and girls do not consider the high cooccurrence between them, which prevents from identifying how heterogeneous groups might distinctly use coping strategies. To address this gap, the current study relies on a sample of 976 adolescents (56.0% girls (n = 547), aged 12–15 y.o., M = 12.92, SD = 0.75) to identify profiles of self-reported internalizing symptoms while properly disaggregating youth’s global levels of internalizing symptoms from their specific levels of anxious and depressive symptoms. The study also assesses whether similar profiles will be identified with the same frequency among boys and girls, as well as the associations between profile membership and coping strategies (problem-solving, social support, cognitive restructuring, cognitive avoidance, and behavioral avoidance) and whether these associations vary between sexes. Bifactor-confirmatory factor analyses confirmed the presence of a global internalizing factor and six specific factors reflecting anxious and depressive symptoms. Latent profile analyses identified three similar profiles among boys and girls but with different prevalence: Low internalizing symptoms (29.97% (n = 164) girls; 70.77% (n = 304) boys), Internalizing and specific anxious symptoms (40.15% (n = 220) girls, 14.75% (n = 63) boys), and Internalizing and specific depressive symptoms (29.86% (n = 163) girls, 14.48% (n = 62) boys). Girls in the Internalizing and specific anxious profile reported more frequent use of four coping strategies compared to boys (problem-solving, social support, cognitive restructuring, and cognitive avoidance). Among boys and girls, the Internalizing and specific depressive profile was associated with the least strategic use of coping strategies (low problem-solving, social support, and cognitive restructuring, and high cognitive and behavioral avoidance). The Internalizing and specific anxious profile was associated with high levels of all coping strategies (except behavioral avoidance). Overall, the study demonstrates that disaggregating global and specific internalizing symptoms allow identifying qualitatively distinct profiles, which then raised questions on the efficacy of the coping strategies used by youth with an Internalizing and specific anxious profile. These results support the adoption of a transdiagnostic approach of treatment based on a holistic representation of all aspects of adolescent boys’ and girls’ internalizing symptoms to better accompany them in the selection of their coping strategies.

This article explores heterogeneity as fundamental to learning. Inspired by Bakhtin's notion of heteroglossia, a design team consisting of an experienced classroom teacher and 2 researchers investigated how a class of 3rd and 4th graders came to understand disciplinary points of view on heat, heat transfer, and the particulate nature of matter. Through a series of planned and unplanned encounters, official versions of the Second Law of Thermodynamics and the particulate view of matter were juxtaposed with varied domains of experience of heat transfer and phase change in water. We analyze the children's discourse to examine how they populated these phenomena with meaning and what they learned in the process. We conclude by describing key principles and a conundrum that emerged from this research.

When looking at groups of people, we can extract information from the different faces to derive properties of the group, such as its average facial emotion, although how this average is computed remains a matter of debate. Here, we examined whether our participants’ personal familiarity with the faces in the group, as well as the intensity of the facial expressions, biased ensemble perception. Participants judged the average emotional expression of ensembles of four different identities whose expressions depicted either neutral, angry, or happy emotions. For the angry and happy expressions, the intensity of the emotion could be either low (e.g., slightly happy) or high (very happy). When all the identities in the ensemble were unfamiliar, the presence of any high intensity emotional face biased ensemble perception towards its emotion. However, when a familiar face was present in the ensemble, perception was biased towards the familiar face’s emotion regardless of its intensity. These findings reveal that how we perceive the average emotion of a group is influenced by both the emotional intensity and familiarity of the faces comprising the group, supporting the idea that different faces may be weighted differently in ensemble perception. These findings have important implications for the judgements we make about a group’s overall emotional state may be biased by individuals within the group.

This study is the first to investigate subject-level variability in sociolinguistic evaluative judgements by 30 adult L2 German learners and explore whether the observed variability is characterizable as a function of individual differences in proficiency, exposure, and motivation. Because group-level estimates did not paint an accurate picture of the individual, we propose methods capable of integrating population-level estimates with person- and ensemble-centered approaches so as to reconcile generalizability and individuality. Using random effects from Bayesian mixed-effects models, we found that global subject-level variability in evaluative judgements was not predicted by individual differences. By building homogeneous ensembles (i.e., subgroups of individuals with similar evaluative judgements), however, it was possible to assess whether ensembles were characteristic of certain levels of individual differences. This ensemble-centered approach presents an innovative way to address the group-to-individual generalizability issue in cross-sectional data and transcend individual variability in order to make tentative generalizations of individual cases to wider populations.
