I love Bootcamps. It's been a little over a year since I started using them, with the idea in mind of sort of a center opening on steroids. I like the concentrated skill building that happens in a short amount of time during Bootcamps and I like the flexibility - you can do a few in a block, like I do, or one at a time, like Ian.
I use the Gradual Release Model when I teach Bootcamps. I start with demonstrating new information, having students draw along with me as I talk. Next I have a group learning component, where students interact, discussing and applying what they've learned.
Next I have a short session of independent practice, then a longer assignment where students are asked to apply new knowledge that they'd like to explore further in a more open-ended format. These learning experiences are a combination of teacher directed and modified choice. Once my the month of drawing, painting, clay and photography Bootcamps that I do with Art are over, my students tend to be comfortable selecting media independently and can successfully navigate open choice in materials. I do Bootcamps with my more advanced students as well, like facial proportions and figure drawing with Art 2. Bootcamps, however you do them, provide a safe jumping off point for students who are used to following directions instead of making decisions.
I'm an high school art teacher who's really interested in student choice and creating opportunities for self expression. I'm also a writer for The Art of Education and co-author of The Open Art Room.
