Joep Eikenboom is a Waldorf class teacher and Extra Lesson practitioner in the Netherlands. He has worked extensively with Audrey McAllen and other Extra Lesson teachers to found remedial education teacher training programs in the United States, Australia, the Netherlands, Germany, Brazil, Spain, Hungary, and Ireland.
The exercises by Audrey McAllen as published in The Extra Lesson are more than just an example of what individual teachers can develop when confronted with the needs of their students. Audrey developed an archetypal concept, rooted deeply in Rudolf Steiner's Anthroposophy, which goes far beyond the individual level. These exercises address the spiritual forces in the body and integrate the movements of students into the universal movements of Earth. Practicing the exercises oneself reveals their effectiveness; studying the concepts from which these exercises are developed deepen our understanding of why they work.
