InterPLAY: A Framework to Describe Play and STEM Engagement at Exhibits for Young Children

open access: yesCurator: The Museum Journal, EarlyView.
ABSTRACT Play‐based STEM learning at exhibits is a feature of children's museums and science centers; yet little is known about how these exhibits support young children's STEM engagement. This study developed and tested the interPLAY Framework to describe play‐based STEM engagement at exhibits for young children.

Narrative reconstruction of the self: Living funerals as rituals of trauma and transformation

open access: yesThe Australian Journal of Anthropology, EarlyView.
Abstract Living funerals mark a radical reconfiguration of contemporary engagements with mortality, transforming death from an imposed ending into an actively authored narrative. This study examines the practice in Hong Kong's hybrid sociocultural landscape, where traditional Chinese death rituals collide with neoliberal selfhood and globalised ...

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

open access: yesJournal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Leveraging Multimodal Large Language Models to Analyse Student Exploration Behaviours in Educational Game Environments

open access: yesJournal of Computer Assisted Learning, Volume 42, Issue 4, August 2026.
ABSTRACT Background Video data provides rich opportunities to examine student behaviour in game‐based learning environments, capturing not only observable actions but also subtle indicators of cognitive engagement. However, traditional video analysis is labor‐intensive, and current applications of AI to this task are limited by models trained on ...

Simulation of Combustion in a Hybrid Rocket Engine

open access: yes, 2023
A numerical investigation on the combustion mechanics of a hybrid rocket engine is performed through unsteady Reynolds-averaged Navier-Stokes simulation. The hybrid rocket engine model is based on an experimental laboratory scale engine design operating on GOX and HDPE as a propellant.

The Interplay of Teacher Agency and TPACK in AI‐Integrated Science Education: Insights From Exemplary Practice Cases

open access: yesJournal of Computer Assisted Learning, Volume 42, Issue 4, August 2026.
ABSTRACT Background Teacher agency plays a pivotal role in technology‐enhanced instruction, yet empirical evidence connecting agency to the practical enactment of specific components of TPACK remains limited. In particular, the intersections between teacher agency and TPK/TCK as enacted practices warrant closer scrutiny.
