When students learn through arts integration, they are engaged in experiences in which they actively build and demonstrate their understanding of both the art form and the other curriculum area.
Thinking about it, I remember art projects and art included into lessons more than almost anything else. The creative parts of those lessons stayed with me, while regular worksheets or lectures were easier to forget because they weren't engaging. I think it’s because art made me get involved and use my own ideas, which helped the content we learned stick in my memory better.
