At negligible cost & increases factual & social education, YES, of course. However, there shouldn’t be a grant needed for teaching specific parts of history. ALL history should be taught to ALL students.
Teach students to consider the facts, research the background, consider differing viewpoints, and to think for themselves.
On that note - how about a textbook committee looking into publishers different versions in different states/regions of our country? How is that rationalized? Opinionated/subjective renditions of history over facts - not acceptable. Federally funded schools should have identical textbooks.
Transparency about the publishers & publishing is needed - especially the financial backing, political/lobby activities, & fiscal participation in PACs, etc.
