Nonverbal immediacy behaviors are underresearched in the online teaching environment. Using social presence theory as a guiding framework, this study explores several online nonverbal immediacy behaviors: emoticons/figurative language, color, cohesion, visual imagery, and audio in course design; response latency, length, time of day, and message frequency in forums; and type and promptness of feedback via grading and email. Coding of 51 online courses found that more consistent use of nonverbal immediacy behaviors was related to students' reports of higher course engagement. However, the nonverbal behaviors most associated with engagement were the ones not used as often. Findings indicate instructors can improve the effectiveness of online learning environments via nonverbal immediacy behaviors.
