Greetings,
I’d try to shift the focus of the class away from the jokesters by first stopping everything and pointing out correct behaviors. Give appreciation to those students that are taking notes and hold up their papers for all to see. Focus on the positives. Reward those that are paying attention. And try to setup a community of healthy choices that are easier to promote than the distracting ones.
Hopefully this helps.
Thanks!
