During the pandemic, people were forced to utilize multiple online learning apps as platforms, allowing them to continue education. Though many people benefit from online learning, the public still holds different attitudes toward it. This research examines the impact of online classes on people's attitudes, with a primary focus on the shift in attitudes toward online learning during the COVID-19 pandemic. It encompasses two main questions: 1. How did the public's attitude towards online learning change during the pandemic on Twitter? 2. What are the differences in the dynamics of the public's attitude towards online learning on Twitter during the pandemic compared to the post-pandemic period? Our team employed a variety of methods to address these questions. They gathered a substantial amount of data and examined specific tweets to gain more detailed insights. The results indicate a change in people's attitudes toward online learning during the pandemic. Initially, many individuals were not fond of it and had uncertainties. However, as time passed and lockdown measures continued, people began to accept and enjoy online learning. The perceptions of online learning differed between the pandemic and post-pandemic periods. After the pandemic, positive sentiments like the convenience and flexibility of online learning became more prevalent. These findings are significant as they help understand how people's opinions about online learning evolved during and after the pandemic and how people accept online learning as an educational technology.
