We describe a 2 h general-chemistry experiment that introduces college students not only to the concepts, synthesis, and applications of nanomaterials at an early stage but also the use of a spectrophotometer for quantification and unknown determination based on Beer's Law. The procedure involves students (1) preparing a nanocomposite by…

This paper illustrates a year-long case study investigating in-service teachers' needs and mentor's practices in implementing cutting-edge research science topics as nanotechnology and plastics in the ocean in primary education. In a Community of Learners design and with the support of a mentor, ten primary teachers implemented in 6th grade…

This article relates a case study on how a conversation with materials and diagrams -- the actual use of materials and diagrams to think, imagine, explain, collaborate, design and build -- featured a certain kind of interplay between material and digital components. The physical components present in this setting included a water wheel, which is a…

Pre-college engineering education has gained traction in U.S. schools over the past twenty years. This growth is evident with engineering emerging as a crosscutting discipline in the Next Generation Science Standards. However, the scarcity of professional development (PD) for K-12 teachers who want to teach engineering and the few PD opportunities…
