摘要：With the popularity of Small Private Online Courses (SPOCs) in higher education, a
plentiful of discussion data has been increasingly generated in SPOC forums. With 752
undergraduates’ discussion posts, this study aims to investigate students’ engagement
patterns within SPOC forums in terms of engagement behaviors and emotions. Firstly,
we designed a behavioral code rule to identify posting- and content-level behaviors,
and examined their association with course performance. Secondly, we built an
emotion lexicon including positivity, negativity and confusion word sets, and adopted
an emotion calculation approach to visualize emotional evolutionary trends and to
examine emotional differences in registration types and course performance. The
results show that, (1) the high-performing group was more active in the most
engagement behaviors except for interactive postings. (2) The registered group
delivered more threads and wrote richer vocabulary in post content. (3) Whether
students were registered for a course or not did not have a significant effect on their
emotional expressions, but the registered group exhibited more confusion in forum
interactions at the end of the semester. (4) Positive emotion was prevailing for the
entire population. Furthermore, compared with the low-achieving group, the highperforming
group had higher emotion densities in three types of emotions.
