Case
Election

teachers wrestle with how to teach the controversial issues and topics raised during the 2016 election.

Solution #1
It is best for teacher to stay neutral when discussing the election, as teacher bias can alienate some students and skew the teacher's own lesson. A good idea is to tackle issues that are found from both the DNC and the GOP. The teacher could also maybe get coworkers with various opinions to review the lesson plan.

I agree with your solution of staying neutral.

Solution #2
Do not show any sort of political favor over a candidate, just teach the appropriate and ethical way.

I agree with your solution

Agreed

Solution #3
Support the class with facts, articles and interviews from both sides. See what the students think of it all themselves. Have them form their own opinions on what they believe they support. They may ask you questions but you must remember you are there to educate, so use only supported facts, not opinions.
Solution #4
Let your students lead these discussions. Offer facts, never opinions.
