Dr. Jo Eaglin has spent many years in education. She has been involved with teachers ranging from kindergarten through 12th grade. In addition, she has worked with educators in higher education for over twenty years. She believes that one must focus on designing curriculum to support teaching and learning at the earliest levels.
Her initial background was in elementary education, leaning towards the teaching of mathematics to K through 4th grade students. After earning an associate’s degree in elementary education, she went on to pursue a BS and MS in biochemistry. As she went forward with her BS and MS, she learned that science was a discipline that many women did not go into. With this, she became interested in learning paradigms, specifically how women are involved in the learning of science and mathematics. This made her decide to pursue a PhD in education, as she realized that multi-modal teaching and learning needs to be at the forefront of education.
As she was teaching at the university level, specifically with Artists, she was fortunate enough to work with Dr. John Dewey’s student, Dr. William H. Schubert. It was here she learned about Progressive education. Dr. Jo Eaglin went on to write, design, and implement many forward focused curriculums in the United States and abroad.
