The NSF COSMOS-NewLAW-CS3 Research Experience and Mentoring for Teachers (REM/RET) is an intense summer program for teachers who learn the basics of wireless technology and how to enhance the teaching material for their students using the predesigned online lessons/labs. The teachers are mentored by NYU, Columbia University, and Lehman College researchers and by the teachers who participated in the program in the prior years. Since Fall 2018, participating teachers have incorporated the science, math, and computer science lab experiments developed through this program within their classrooms, giving students hands-on experience with the next wave of mobile technology. More details are available on the COSMOS website and video.
