Harmfulness Score: A Data‐Driven Framework for Ranking Environmental Risks of Microplastics

Macromolecular Rapid Communications, EarlyView.
Using machine learning and bibliometric sentiment analysis on over 100 000 abstracts, this study introduces the Harmfulness Score to rank environmental risks of microplastic polymers. Polystyrene and polyethylene emerge as top‐risk materials, supporting targeted regulation and evidence‐based policy recommendations.

Establishing a Model for Serious Science Game Design for Elementary Learners: A Longitudinal, Mixed Methods Study of Serious Game Design Mechanics That Facilitate Science Learning

Science Education, EarlyView.
ABSTRACT Immersive learning environments, such as serious educational games (SEGs), offer promising opportunities for enhancing elementary students' science learning outcomes and fostering their interest in science. These environments allow learners to explore scientific phenomena in ways traditional instruction cannot replicate.
