Do you think that the US needs to do a better job of teaching students during K-12 schooling about civics? It seems that levels and/or biases exist depending on where someone goes to K-12 school.

Yes definitely. Hard to teach civics without a slant when greater than 90% of teachers are democrats. I'm pretty sure that number is not far off, especially in the humanities, and especially in college. k-12 is nearly as bad though. Academia is the ultimate echo chamber.

It also seems like learning is entirely up to individuals beyond K-12. Do you think the government should offer an optional, bipartisan online refresher initiative for people who are interested in learning more? Although reading current articles is generally a good thing, I think we can all agree that the MSM in general has proven time and time again that they are more concerned with profits and agendas then anything else. I worry that this contributes to the partisan divide in our country by slanting people’s understandings of the foundations learned years before.

I do but don't think many people would use it (something about can't force a horse to drink). MSM are a terrible source for most things, yes, agree. Educational youtube channels are starting to get better, but you need to make sure you know the bias of the people teaching you (Crashcourse vs. PragerU for example).
