The goal is to get students to behave as artists behave. This comprehensive coverage of habits and standards means the order in which the projects are presented is interchangeable. I have my students select by consensus the order of the projects based on their interests to set the content of a given course.
The quality of learning sustained rather than the number of projects completed drives the class. Broad exposure to many concepts or techniques in a course does not offset what a student will learn through the focus and investigation necessary to achieve a deep understanding of a fewer number of topics. Professional judgment as the teacher on the level of learning taking place in the classroom should determine when to move on to the next project, not some arbitrary schedule in a curriculum map.
Most of your students will not go on to pursue art at the university or professional art school level, but having an authentic art experience benefits all students who take art.
