title = "Pedagogical Communication Language in Video Lectures: Empirical Findings from Algebra Nation",
abstract = "Online tutoring has become a primary instructional delivery method with increased global health restrictions. Providing effective communication strategies is critical in video lectures to reduce the physical gap between the tutors and learners for effective learning. Hence, this study presents empirical findings regarding the communication strategies of algebra tutors in online video lectures. We used two advanced psycholinguistic tools, Coh-Metrix and S{\'E}ANCE, to investigate how the algebra tutors explored different language choices with specific sentimental values. In addition, the different teacher-talk strategies were identified within levels of their pedagogical discourse marker use. The results revealed the importance of linguistic and sentimental indices to understand the communication strategies of the tutors providing instruction on various algebra topics. The findings further suggested that tutors tend to focus on providing intentional language cues in the form of pedagogical discourse markers to help build rapport with the learners in an online learning environment.",
