This study is intended to analyze the impact of online and offline mixed teaching methods for university students due to COVID-19. The study was conducted when the government relaxed the restrictions imposed during the COVID-19 period. So, the questionnaire was created using Google Forms and then 550 Questionnaires were distributed via email. On 15 November 2021, data collecting began and ended on 16 December 2021. To test the hypotheses, this study utilized the structural equation modeling technique. The study result shows that the factors of technology quality, teaching tools, teacher presence, students' expectations, interaction, and course content all have an impact on student satisfaction and performance. Students' performance will improve if they are satisfied with the learning approach they are using. Any learning method's success or failure is determined by a student's performance. According to the study's findings regarding student performance, the usage of an online and offline mixed teaching method had a positive impact on students' learning during the pandemic era caused by COVID-19. Therefore, the study shows that the mixed learning method is growing in the post-pandemic learning environment, most notably making students more flexible and involved in the learning process.
