Despite the popularity of the Massive Open Online Courses, small-scale research has been done to understand the factors that influence
the teaching-learning process through the massive online platform.
Using topic modeling approach, our results show terms with prior
knowledge to understand e.g.: Chuck as the instructor name. So, we
proposed the topic modeling approach on helpful subjective reviews.
The results show five influential factors: “learn easy excellent class
program”, “python learn class easy lot”, “Program learn easy python
time game”, and “learn class python time game”. Also, research
results showed that the proposed method improved the perplexity
score on the LDA model.
