The aim of this study was to determine the learning styles of prospective chemistry and science teachers, and to examine the effects of different learning styles on their self-regulated learning skills. The survey method which is one of the quantitative research methods was used in this study. A total of 251 prospective chemistry and science teachers from the Departments of Chemistry and Science Education of three different public universities participated in the study. The Self-Regulated Learning Skills Scale was used to determine the self-regulated learning skills of the prospective teachers, and the 'Maggie McVay Lynch Learning Style Inventory' was used to determine the prospective teachers' learning styles. The results showed that 61.8% of prospective chemistry and science teachers had a visual learning style, followed by a moving or kinaesthetic learning style (19.9%) and an auditory learning style (18.3%). Furthermore, a statistically significant difference was determined in the prospective chemistry and science teachers' lack of self-directedness scores.
