### Topics Detected (RQ1)  
By observing the terms associated with each topic and the inter-topic distance when assigning different topic numbers, batch sizes, and random states, six topics are finally determined as the optimal result. Figure 1 shows three of the six topics, Topics 3, 5, and 6, distinct from each other, while there is an overlap between the three remaining topics (Topics 1, 2, and 4). Figure 2 displays the fifteen most relevant terms for each topic. Figure 3 depicts the Word clouds generated from the six topics.  
Among the three distinctive topics, Topic 3 is associated with _teacher_, _thing_, _happen_, and various adjective terms such as _funniest_, _weirdest_, and _embarrassing_. It reflects the abnormal, strong, and diverse incidents and interactions between learners and educators during online classes. Topic 5 is featured with the terms _help_, _exam_, and _post_, which implies that learners seek help in exams and assignments when taking online classes. The salient terms _math_, _statistic_, and _software_ indicate that learners experience more difficulties in science and engineering classes, with _mene_, _made_, _time_, and _today_ being the most dominant terms in Topic 6. It illustrates that online class has become a popular resource for meme-making. In other words, it has become a part of the subculture among the young generation.  
Among the three overlapping topics, Topic 1 covers the largest number of words, featuring _teacher_, _student_, and _time_, about small things frequently happening in online classes. Topics 2 and 4 are closely associated with each other. Topic 4 includes the _bored_, _tifu_, and _camera_, which emphasize the negative aspect of daily online classes, while Topic 2 is more positive since it includes _like_, _friend_, _love_, and _fun_.
