From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Teachers' Pedagogical Reasoning and Students' Three‐Dimensional Learning

Science Education, EarlyView.
ABSTRACT This article reports analyses of data from a design‐based implementation project focused on middle‐ and high‐school science teaching. Drawing on teacher interviews and surveys as well as student learning evidence, we examined the relationships between teachers' pedagogical reasoning and their students' three‐dimensional learning. Most teachers
