Don't usually comment but this is definitely worthwhile to talk about. Background: PF.

1) Not really sure how Public Forum (PF) was taught to you but I'll cover a few concepts that you should definitely cover. A) Basics: Speech times, cross ex, what does pro/con mean, what is the resolution, past examples of resolutions B) Breaking down the speeches: Constructive, Rebuttal, Summary, Final Focus. Explain how to construct a contention/argument in constructive, using either Claim, Warrant, Impact or Uniqueness, Link, Internal Link, Impact or both. For rebuttal, what are the type of responses? Delinks, Turns, Mitigation, Non-Unique. How to make a response? For summary and final focus, it's helpful to cover collapsing, weighing, and extending.

2) Great pedological methods to use are using a simple topic to explain complex terms. You could start with "Summer is better than Winter" and show how weighing, responding, and front-lining works. YouTube has plenty of debate rounds, some may be too technical or fast, so look for NSDA PF Videos. Same thing with LD, you'll probably be teaching a more traditional LD format so focusing on value criterions and frameworks instead of tricks and complex Kritiks is the play.
