Opportunities for improvement in class 2	Notes/comments from class 2
Uncertainty regarding the long-term effectiveness	Currently, we do not have a standard procedure in place to monitor the extent to which students continue to engage in R coding after class. Additionally, we lack knowledge regarding their proficiency in independently solving coding challenges in advance. (author PK note)
Teaching assistantship	“We have no teaching assistant during the class, and it made some practice sessions run slower because some of us encountered specific problems during the practice.” “It would be nice if teaching assistants can join these courses to help us during the practice session.” (comments from students)
