This mixed-methods study examined Grade 4 students’ growth in two types of civic competencies—argumentation skills and disciplinary thinking, and how civic competencies interweave and co-develop over an academic year in the context of an interdisciplinary social studies curriculum called Digital Civic Learning (DCL). A total of 106 fourth-grade students (38.7% girls) and 6 social studies teachers participated in the study. Quantitative evidence indicates that students in the DCL curriculum significantly improved in their argumentation skills (argument-counterargument integration, claim-evidence integration) and disciplinary (...) thinking. These civic competencies became more strongly associated with each other by the end of the curriculum. Multiple case studies revealed how two students synergistically applied their evolving argumentation skills and disciplinary thinking through distinct learning pathways. These results paint a complex picture of the development of students’ disciplinary thinking and integrating of argumentation skills, and the role of the curriculum in fostering the concurrent development of these civic competencies. Findings align with our overarching assumption that, through collaborative discourse and immersive learning about complex social issues, students can leverage their disciplinary thinking during argumentative social interactions, grappling with solutions and seeking common ground; continuous discourse among peers further enhances argumentation skills while honing disciplinary thinking. This study bridges the research-practice gap by providing evidence for the co-development of argumentation and disciplinary thinking within social studies classrooms. Our findings underscore the importance of inquiry-based learning, aligning with the College, Career, and Civic Life (C3) Framework, fostering critical civic competencies, and empowering students to actively participate in democratic processes. Particularly in this digitalized society, DCL emerges as a promising approach to integrate disciplinary thinking and argumentation skills across both physical and digital environments, fostering informed and active citizenship among students.

Most children experience some form of grouping in the classroom every day. Understanding how teachers make grouping decisions and their impacts on children’s social development can shed light on effective teacher practices for promoting positive social dynamics in the classroom. This study examined the influence of teachers’ grouping strategies on changes in young children’s social experiences with peers across an academic year. A total of 1,463 children and 79 teachers from kindergarten to third-grade classrooms participated in this study. Teachers rated (...) children’s behavioral problems as the most important consideration when creating seating charts or assigning children to small groups. Promoting existing or new friendships was rated as the least important consideration. Heterogeneous ability grouping, rated as somewhat important by the teachers, was associated with a decrease in children’s friendships and yet also a decrease in girls’ experience with peer conflicts. Our findings begin to fill in the gaps in the literature on the social impacts of ability grouping for young children. (shrink)
