The document outlines three phases of teaching: pre-active (planning), interactive (execution), and post-active (evaluation). It also describes three levels of teaching: memory (thoughtless), understanding (thoughtful), and reflective (upper thoughtful). At the memory level, the goal is factual recall and reproduction. The understanding level aims for comprehension, interpretation, and application. The highest reflective level focuses on developing critical thinking through problem-solving, analysis, and independent decision making. Different teaching methods and evaluations are used depending on the specific phase and level being targeted.
