This study explored and examined students' perceptions of teacher confirmation, those behaviors that teachers engage in that make students feel confirmed as valuable, significant individuals, as experienced in online courses. With over 450 students' written descriptions of experiences in online classes across three different universities, this study provides an important initial examination of teaching practices in the online context. While prior research has situated study of students' perceptions of teacher confirmation in the traditional in-person course experience, the current project extends understanding of teacher confirmation into the online setting. The study provides detailed descriptions, in students' own words, of specific tactics instructors can use and avoid in order to promote feelings of confirmation in their students.
