This is discussion about GeoFORCE Texas.
This is a very innovative project. It is exciting to see low-income students of color being exposed to real-world science, as well as having the opportunity to travel to different parts of the country. I am sure that these experiences will stay with them for the rest of their lives.
Although I understand why GeoFORCE targets students with A's and B's, I think that, if you really want to target students at risk, you might want to consider finding a way to impact students making a C or lower. Perhaps GeoFORCE students could create a peer tutoring program at their schools for students who are receiving a C or lower in their mathematics classes.
In terms of mentors, have you reached out to the African-American Fraternities and Sororities, particularly in the Houston area. Also, the National Society of Black Engineers and the 100 Black men might be good resources. I am sure there are Hispanic/Latino counterparts to these organizations as well.
