This study was conducted to determine the 11th-grade high school students' transfer levels of the modern physics topics to daily life in the context of the physics course. The sample of the study figured in the form of the mixed method constituted 314 11th-grade students selected with the cluster sample method. The Modern Physics Success Test (MPST) and Modern Physics Transfer Test (MPTT) developed by the researchers were used in the study. The study process was conducted quantitatively and qualitatively. The correlation between the MPST and MPTT scores of the students was identified in the quantitative section while the students' transfer levels of the modern physics topics to daily life were determined in the qualitative section. As a result of the analyses of the study, a weak, positive and significant relationship was found between the MPST and MPTT scores. In addition, It was revealed that the students' transfer levels of the modern physics knowledge were zero transfer, deficient transfer, and complete transfer and it was identified that the level of complete transfer was considerably low. Regarding the transfer of the modern physics knowledge to daily life, the topics, which complete transfer levels were the highest, were found as "Photoelectric Incident" and "Black-Body Radiation", and the topics, which complete transfer levels were the lowest, were detected as "Matter Waves" and "Pauli Exclusion Principle". Furthermore, it was also identified that the students' transfer levels varied according to other modern physics topics.
