This is not a new paper. It appeared in AJP in 2006. But for some reason or another, I came across it lately in one of my searches, and I don't think I've highlighted this before. This is an excellent presentation by James Hartle on the rationale to introduce General Relativity to undergraduate physics students. This is no easy task because GR does require a bit of sophistication, especially with mathematics. But beyond that, the paper is actually a good intro to GR where one can actually get a taste of basic GR concepts.
A good paper to read.
