An emphatic “no” to this question! The Spectrum was developed in the Physical Education discipline because Dr. Mosston was a Physical Education professor at Rutgers University (USA) when he first authored the work. However, Mosston, Ashworth, and their colleagues knew immediately that the Spectrum of Teaching Styles, both as a theoretical model and as a practical tool, had universal applicability in terms of content, learners, and context.
In 1973-1980 Mosston and Ashworth received a Federal grant that provided them the opportunity to expand and implement the Spectrum in all subject matter fields, all grades, and various ability designations in the public school classrooms in New Jersey. Additionally, Dr. Ashworth taught the Spectrum to undergraduate and graduates in the Elementary Education Department at Florida Atlantic University for 20 years (1987-2004). Since its inception, the Spectrum has received worldwide recognition and has been translated into multiple languages.
