As TeamStar says, welcome.
Just to clarify the
"Research" concept, the very popular German game series
Anno (1602 A.D., 1503 A.D., etc.) used it extensively.
The schools were at two levels, After they were built, by spending money in combination with attendance - a series of 'research steps' could be taken. Those steps generally opened-up construction of additional buildings.
My point is that the concept is well known to European game developers.
It could be adapted to T3. However, the developers might not find it consistent with the theme of
Tropico. After all,
Tropico is a back-water, small island which is home to a "tin-pot" dictator. The schools are merely glorified trade schools and not sophisticated academic research centers. The kind of improvements you seem to have in mind are more likely to come as foreign aid from the US or the USSR.
If there are not open pit mines, there would be no annimation of mining. That's no fun.
