Rigidity Of Class Ability Grouping Practices In Australia, Olivia Johnston, Christa Norris, Wei Zhang

Research outputs 2022 to 2026

Inequity in education is pronounced when data is used to form rigid class ability groups. Rigid grouping means that students with backgrounds that disadvantage them in education can be locked into low ‘ability’ class groups. In contrast, informed and flexible use of data can support adaptable and heterogeneous ability grouping, which better accommodates the diverse needs and potentials of students. This approach ensures that students are not permanently categorised but can move between groups as their abilities and needs evolve. Research drawing on international data sources like the Programme for International Student Assessment (PISA) oversimplifies the range of ability grouping …

Finding Time-Proximity Communities In Temporal Heterogeneous Information Networks, Yifu Tang, Chengfei Liu, Lu Chen, Rui Zhou, Jianxin Li

Research outputs 2022 to 2026

Community search in heterogeneous information networks (HINs) often neglects temporal dynamics, yielding structures that poorly reflect real-world interactions. We introduce the Temporal HIN Community Search (THCS) problem and propose a novel core model that captures both structural cohesiveness and temporal relevance. Our model uses a time span constraint to ensure interaction recency and a query interval for flexible temporal exploration, filtering irrelevant connections while preserving structural density. We develop two efficient online algorithms—Center-based Sliding Window search and Incremental Center Expansion—that exploit meta-path symmetry and dynamic connectivity tracking. For frequent queries, we design a Temporal HIN Core Interval-Index (TCI-Index), organising minimal …
