I am mostly a direct teaching type of style with tons of scaffolding. That is where you will see a lot of my lessons are powerpoints with just problems, where I would teach/talk my way through the lesson.
While some teachers like myself, just needed the problems, there are teachers out there that do need help with how to teach a specific lesson. I make my lesson plans where you could literally read them like a script.
However, I had extensive professional development on PBL, and brought it into my classroom for two years. That is why you will also find some PBL projects that I literally made and designed on my own, and completed multiple years in my classroom.
