Gregorc learning styles and achievement in anatomy and physiology.

Results from the Gregorc Style Delineator (GSD), administered to 260 undergraduate nursing students, were compared with achievement scores in a human anatomy and physiology course. Factor analysis and VARIMAX rotation demonstrate that there is no relationship between any of the four learning styles allegedly identified by the GSD and achievement in anatomy and physiology. Factor analysis also shows that the GSD measures only a single bipolar scale of sequential vs. random ability rather than two bipolar scales comprising four learning styles, as suggested by Gregorc. These findings question the validity of the GSD and recommend discontinuing its use as an indicator of learning styles.
