This study aims to determine the learning styles of Turkish teacher candidates before and during the online learning process and whether this varies according to gender. The research was designed through the descriptive survey model. The study group of the research consists of 500 teacher candidates. The Grasha-Riechmann learning style scale was used as a data collection tool in the study. Data analysis was carried out using descriptive statistics and an independent sample t-test. As a result of the research, it was determined that Turkish teacher candidates preferred the dependent learning style at the lowest level both before the online learning process and during the online learning process. It has also been determined that they use moderately independent, collaborative, competitive, participant, and avoidant styles. Lastly, Turkish teacher candidates' learning styles differ according to gender before and during the online learning process.
