That all sounds so cool! I love that you’re incorporating multimodal writing (i.e. using video, audio, and visual modes of communicating). I think a problem-based project or social justice component would naturally fit VERY well into this structure and would be highly engaging for your students! That to me is where you’re project is leading. Kelly Gallagher is an author that would suit your teaching style really well (though he is for writing, specifically). With problem-based learning, you’re giving the kids a genre of topic (i.e. natural resources, plant science, animal science, etc), and then they look to see what problems they notice in their community. Then, they start to ask “why do those problems” exist, and they come up with solutions to them. This also wouldn’t be too outlandish to apply in a student teaching scenario. You can fit it in with the curriculum you’re using, but would just need to adapt the curriculum to be more community based, if that makes sense.
