Testing Times: A Structure/Agency Perspective on Becoming a Science Teacher in a Competitive, Exam‐Based Teacher Selection System

Science Education, EarlyView.
ABSTRACT While extensive research exists on science teacher shortages, less attention has been directed toward countries facing the opposite challenge: an oversupply of science teachers. This study examines the experiences of prospective science teachers in South Korea, where passing a high‐stakes, annual competitive examination is a prerequisite for ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Reconciling Granular Hydrogel Microstructure and Mechanics via a Temporary Thermo‐Responsive and Cell‐Invadable Matrix

Small, EarlyView.
Thermo‐responsive granular hydrogels (TRGHs), composed of microparticles and an interstitial matrix, exhibit thermo‐responsive mechanical properties and allow cell infiltration. This system effectively addresses the conventional compromise between mechanical strength and porosity observed in granular hydrogels.
