Which method is discouraged when rehearsing lessons?

Memorization of the lesson is discouraged during rehearsals because it can lead to a mechanical delivery that lacks engagement and responsiveness to students' needs. When instructors rely solely on memorization, they may struggle to adapt the lesson to the dynamics of the classroom or to address questions and comments from students effectively. This could hinder the learning experience, as students typically benefit more from a natural, interactive presentation that feels authentic and allows for improvisation based on the flow of the lesson.

Rehearsing in parts, while it might seem counterintuitive, can actually help instructors break down complex material into manageable sections for better understanding. Whole lesson rehearsal allows instructors to practice the entire flow of the lesson, which provides a comprehensive understanding of how each component interacts within the broader context. Criticism from peers, when constructive, can offer valuable insights that improve teaching methods and lesson delivery.
