The 4th Industrial Revolution highlights the importance of technology-based approaches in mathematics education to enhance teaching methods and student achievement. This study investigated the impact of visualizing mathematical concepts using technology on the effectiveness of online mathematics classes. Conducted during the unique COVID-19 pandemic period in 2021 with engineering certification students at G University, the research provides insights into technology's essential role in evolving educational environments. The experimental group, utilizing flipped and blended learning with video-recorded Calculus II content, showed enhanced class effectiveness. While final exam scores tended to increase over midterm scores in the experimental group, this improvement was not statistically significant. However, this non-significant increase in scores suggests a potential positive trend for future investigation in longer-term studies, implying potential for enhanced conceptual understanding and expanded thinking. Also, attitude tests revealed that technology-assisted visual understanding significantly improved students' comprehension and interest in mathematics. This suggests the potential for technology-based mathematical visualization to foster expanded thinking and positive attitudes, offering foundational data for future online mathematics education development.
