Care Praxis–Driven STEM Design for Sustainable and Just Communities in Middle School
Journal of Research in Science Teaching, Volume 63, Issue 7, Page 671-690, September 2026.ABSTRACT Despite the growing interest in incorporating care ethics into STEM education, these topics are rarely integrated into K‐12 standards and pedagogical practice. We explore how care praxis, a political and ethical approach to STEM education, supports students' sense‐making in addressing real‐world problems throughout STEM design, merging social,

Maglev trends in public transport: the perspectives of maglev transportation systems
Transportation Systems and Technology, 2017 The idea of considering Maglev systems challenges established ways of thinking on how to deal with an increasing transport demand. Today, the railway industry seems focused on traditional business models that profit from friction, wear and tear of established conventional transport systems.
