This actually clears up a question I've had for a while... I've heard teachers refer to "the curriculum" in many ways, and I haven't actually had a clear picture of what "the curriculum" really means. The formal curriculum might (I imagine) be dictated more strongly by the district or state, while the instructional curriculum is left more to the digression of the teacher (or district in some cases). I'm really looking forward to Curriculum Design next year... I think it will help me make more sense of this entire situation, which seems to vary so greatly depending on what situation one lands in.
p. 312 "How much can realistically be accomplished will depend on the contact time the teacher has with the children. An ideal would be thirty minutes daily with each class. Much more common is two to three times a week for thirty to forty minutes each. An inadequate program is thirty minutes per week or less."
Thinking back to my own music education experience, I remember in upper elementary school having music two or three times a week (though I was also a member of the handbell choir which met once a week during lunchtime). In middle school, I was in the choir, which was separated male-female. The girls met during the music period on MWF, with study hall during that time on Tu/Th, and the boys vice versa. I think that actually worked out pretty well, with the exception of the fact that our study hall was supervised by an art teacher who was in the middle of a nervous breakdown. We also had the opportunity to audition for the school musical in middle school, which rehearsed for two hours after school 4 or fewer days per week. In high school, I was a member of the women's choir which met every day for 45 minutes, which was great. I was also a member of a women's ensemble which met before school for 45 minutes twice a week, and participated in a music theory class which met daily for 45 minutes during my senior year. Senior year, I had music for a over two hours twice a week, not counting my private piano lessons, voice lessons, and church music experiences (which were extensive). As someone who is considering the possibility of working in a church setting (as an organist and/or choir director), I also think about what I am learning in my music education classes in that context - how would I apply what I am learning to teaching a group of children once a week (rehearsal) for bi-monthly performances (the service itself)?
p. 323 "Units have the advantage of allowing students to become deeply immersed in a topic over a period of time."
I like the idea of units because of this reason. As a student, I've always appreciated the contextualization of skills. I remember we did a unit on Lewis and Clark/Westward Exploration in 5th or 6th grade that was tied into literature, history, geography, and other classes I'm forgetting. We were completely immersed in the topic as our teachers created experiences for us that put us in the position of explorers in the early 1800s. I still remember the experience of eating the mystery food (which turned out to be cold oatmeal) given to us by "friendly Native Americans," played by some of our 6th grade classmates. I wonder what the experience would have been like if the entire school had been involved instead of just our teaching team. I don't know if that would be realistic for a public school, but I'm still a big fan of the cross-subjects curricular unit (or just a unit within a single class), because it gives context for the information and skills being learned.
"Remember, the highest form of fun is to gain a feeling of competence, because confidence emerges from knowing you have achieved something and can use it for the rest of your life." (p. 322) I wanted to add this as a side note... because it made me laugh out loud when I was reading.
