Muska observed that his students flowed easily in their learning experiences from Command to Discovery. However, many of his colleagues and the Physical Education profession posed a greater challenge.
The Spectrum theory did not initially receive standing ovations and applause. In fact, the theory and Muska were seen as threats to the establishment. His beginning message about the Spectrum theory too often attacked physical educators for their dominant Command Style teaching approach. Instead of introducing teaching styles akin to Command Style-A, the Practice Style-B or Reciprocal Style-C, he chose a style opposite to that most familiar to the profession. He presented the virtues of the Discovery Styles. These teaching approaches were viewed as shifting far too many decisions to the students, and they encouraged students to design content that was outside the established protocol. Such teaching was viewed as heresy.
In spite of the professional resistance, during Muska's Rutgers years he was invited to numerous conventions to speak about various aspects of the Spectrum. There were moments of tremendous accolades and times when the applause was barely audible!
Many PE organizations literally banned him from speaking at conferences. Not only was the Spectrum content heresy, but also they found fault with the aggressive manner in which Muska presented his work. His tender charm applied to children but not always to his colleagues. The more his ideas were rejected, the more pronounced his impatience became towards the field. Many student organizations supported his ideas and invited him to speak; however, this created a challenge since he was banned from many major conferences. The students solved the restriction by sneaking him through the back door into their designated presentation rooms.
