One of these programs is Frontiers, in which I taught the physics track from 1994-2019, a period of 25 years. I had about 10 students a year in the first decade, but after that the number steadily increased and finally got capped at 22 for space reasons. The students came from all over the US, but with the New England region being the clear winner, and they also came from about five to seven countries abroad (with South Korea being the winner in terms of being the furthest away). Quite a few of the students went on to major in a STEM field at WPI and many others did the same elsewhere. Teaching in Frontiers was both an exhilerating and rewarding experience for me -- I say exhilerating, because we always managed to do so much in just two weeks. In 2020 the program got canceled because of Covid and I decided then to hang up my socks and let my younger (and very competent) colleagues take over. I have many good memories and tons of pictures and memorabilia from over the years, but unfortunately not the time or energy to put them together in a coherent fashion and so will just present a random sample here. My fond greetings to any past students who happen to visit this site. Do write and tell me your stories, I am always happy to hear from you.
Below I list a number of resources that may be found useful by STEM educators at WPI and elsewhere (my list is slanted heavily towards physics and math, as these are the areas I know best).
First I'll mention a useful compilation by WPI:   K-12-STEM-Resources
Here are a number of websites that focus on physics activities, demonstrations and other useful material:
Here are a couple of websites that focus on math:
Finally, here are some articles/reports I have written to spread
a greater awareness of STEM among
high school and college
teachers and students:
