Teaching presence facilitates students' social and cognitive presence in online courses. Instructor interaction in discussion forums, a widely adopted instructional strategy, establishes teaching presence but research on the optimal frequency and content of instructor interaction in discussion is underdeveloped. This research evaluated 1625 instructor posts in 36 graduate-level courses in education to determine their impact on students' perceptions of the quality of the instructor and course, students' perceptions of their learning, and students' actual achievement. Findings suggest the frequency of instructor interaction in discussion has no effect on student outcomes, but posts that are instructional improve students' perceptions of their learning, and posts that are conversational improve students' perceptions of instructor and course quality, and their actual academic achievement. Implications for instructors and policymakers are addressed.Keywords: Online learning, instructional strategy, instructor engagement, Community of Inquiry, teaching presence, discussion, instructor interaction Hoey, R.

Examining the Characteristics and Content of Instructor Discussion Interaction upon Student Outcomes in an Online CourseThe literature on distance education is unwavering about two conclusions: adult students should be in control of their own learning (Knowles, 1988;Merriam, Caffarella, & Baumgartner, 2007) but want their instructors to be engaged in their courses (Mazzolini & Maddison, 2007). What is not clear are the types, frequency, and characteristics of instructor engagement that result in the most significant student outcomes (Baran, Correia & Thompson, 2011;Kauffman, 2015;Means, Toyama, Murphy, Bakia & Jones, 2010). This research explored one common type of instructor engagement-interaction in discussion forums-to determine the extent to which frequency and contents of instructor discussion interaction impacted students' academic and satisfaction outcomes. Findings may inform policies regarding instructor engagement in online courses.
Theoretical FrameworkIn their highly regarded principles for good practice, Chickering and Gamson (1987) lauded the impact of interaction between the faculty and students, reciprocity and cooperation between students, and active learning of the content. Moore and Kearsley (1996) noted that three critical interactions must take place for students learning online: teacher-student interaction, student-student interaction, and student-content interaction. Similarly, Garrison, Anderson, and Archer (2000) suggested an online course becomes a Community of Inquiry (CoI) when students experience teaching presence, social presence, and cognitive presence that foster deep and meaningful learning. Teaching presence is "the design, facilitation, and direction of cognitive and social processes ...
