Interesting question! High school is the most important part of the education and your idea is definitely encouraging for students to pursue their career in STEM. I have a couple of suggestions from an international student perspective.
First, target the countries that you would like to visit in Phase I. Sign MoUs with the selected high schools which prioritize STEM courses. However, third world countries have huge population and it is not easy to reach out to every good school. You might have to pull together a committee to make sure passionate schools are visited.
Through the MoUs, create high school level projects in collaboration with graduate students in the US who are engrossed in interesting research such as NSF funded, for example (Took this example, as I was funded through NSF I Corps Team program in my grad school). Invest and bring in the students who were selected in Phase I and assign them to the respective grad schools for a week. This encourages every high school that has participated and every student who was involved in this program to learn, contribute, and succeed in STEM areas.
Moreover, the exposure to the sophisticated engineering infrastructure might highlight prodigies and contribute to innovation in STEM areas.
Hi Aparma, thank you for your comment. Indeed, it is a challenge and yet a wonderful opportunity to inspire and motivate your children to explore the world of Mathematics, Science and Engineering.
If one introduces university subjects to middle- year students (8 to 11 year olds), they would be easier to attract when in high school, according to my experience.
Thank you Michael, I do Igree. It is at that tender age that students may discover subjects that they find interesting and are exciting to learn more. One on my best teacher I remember were teachers of Math and Physics my Elementary School. I was about 10-12 years old then.
