Interesting topics! By myth production, I’m assuming this is like ‘myths & legends’ or ‘urban myths’, ‘folk tales’ kind of thing? I like the sound of that topic and it has so many possibilities for engaging lessons.
I’d start by asking the students what myths they know of. Depending on their backgrounds, you might get some really interesting stories.
Then you could look into why myths exist in the first place. What purpose do they serve? How do they get passed on? Do they have greater meaning?
A lot of cultures have similar myths too, even though you’d think they’re not related or have communication with each other, e.g. nearly every culture talks about dragons, etc. You could bounce off the students’ stories with this. I doubt they would have told each other before, but I’d be banking on them all knowing similar myths to each other. How do you myths pass on? How are they created?
The phrase 'myth vs reality comes to mind. You could make the point that some myths come from true events. You could have a ‘on insta vs real life’ meme to begin the lesson.
You could give them a day-to-day happening at the school e.g. assembly, and ask them to do a short creative piece turning into a mythical legend.
Not too sure, but there’s definitely some great opportunities to come up with some awesome lessons.
