The teachers will learn about basic principles of wireless communications, including topics such as radio propagation and networking. This will be done using the web-based lessons/labs that were designed by 6-12 teachers who attended the program in prior years. The lessons are built to support NYC 6-12 curricula, on STEM subjects such as math, physics, biology, and other live sciences, computer science, communications, and similar. The teachers will learn how to use the lessons/labs and how to support their own 6-12 students in running the online labs during the academic year. The instructional material for teachers consists of lesson plans, slides, videos, and running the online labs. The teachers will be mentored by graduate students from research laboratories at the universities and by teachers who attended the program in prior years who developed the 6-12 lessons.
