The classroom experience contains an infinite number of variables that cannot realistically be related to in any manageable teacher's manual. When manuals aim at being "practical", what is produced is often something that looks like practicality, but is not. Curriculum-writing needs a new approach, intended to educate teacher rather than students. Such curriculum-writing can be described as "rehearsal curriculum". A rehearsal curriculum allows the teacher to work through a process of learning, as a "rehearsal" for directing his or her students through that same process. A rehearsal curriculum is written in a way that also motivates the teacher to learn. (Contains 2 tables and 1 note.)
