Suggestopedia is a teaching method developed by Georgi Lozanov based on how the human brain learns most effectively. It incorporates elements like relaxing music, peripheral learning through environmental cues, and role-playing to create a low-anxiety environment where students can utilize their full mental capacity. Key aspects include comfortable seating, Baroque music played during lessons, using indirect learning like posters, free errors by students, and integrating music, drama and art into lessons. The goal is to "desuggest" psychological barriers through suggestion and authority of the teacher to facilitate rapid language acquisition.
