Group work in secondary school classrooms is consistently disrupted by three structural problems: unbalanced group formation, social loafing, and free riding. These problems undermine collaborative learning and burden teachers who rely on manual and unstructured grouping methods. The following research question is explored: What is the current evidence regarding within-class ability grouping, social loafing, and the development of data-driven group formation tools in secondary school and what are the implications for classroom practice? The objective is to systematically synthesise empirical evidence on these three areas and draw clear conclusions for secondary school educators and educational tool developers. A systematic search was conducted in SCOPUS and Google Scholar following PRISMA guidelines. Studies published between 2022 and 2026, written in English, and focused on ability grouping, social loafing, free-riding, academic performance, and student well-being at the secondary school level were included. 24 studies were included and analysed in five themes: ability grouping concepts, academic and psychological impacts, social loafing issues, and data-driven tools to create groups. The results indicate that ability grouping has a positive effect on achievement when it is well structured but has a negative effect when it is poorly structured and taught, leading to psychological harm and social loafing. An emerging trend toward algorithmic group formation tools is found that are superior to manual processes in achieving academic, demographic, and individual accountability. Based on the evidence presented in this review, it is concluded that secondary schools need to go beyond the manual grouping system and use evidence-based tools, which make the contribution of individual students visible, measurable and consequential to achieve true collaborative learning outcomes. This paper introduces BlendEdu, a novel contribution that is the first web-based, data-driven group formation tool specifically developed for secondary school classrooms, as a research-based intervention to end grouping chaos and create measurable classroom cohesion.
