Abstract Grain morphology is a fundamental characteristic of lunar soil that influences its mechanical properties, sintering behavior, and in situ resource utilization. However, traditional two‐dimensional imaging methods are time‐consuming and lack full three‐dimensional (3D) structural information. This study presents an automated deep learning‐based

Integrated STEM conceptualizations among teachers following a professional development program
Abstract Because teachers are now more often expected to develop integrated STEM lessons, it is essential to understand their conceptualizations to be able to support them effectively. This qualitative study explored teachers' integrated STEM conceptualizations upon participation in an engineering‐focused professional development program of 4 days ...
