This study investigated college student perceptions of the (in)appropriateness of instructor disclosures and perceived functions of instructor disclosures. An interpretive analysis of 35 college students identified that family relationships, life experiences and background, and everyday talk and activities were forms of appropriate disclosures; whereas, intimate relationship details, personal problems, personal opinions, and drinking behavior were considered inappropriate topics for instructors to disclose. In terms of the function of instructor disclosures, students perceived that these disclosures worked to humanize instructors, make instructors approachable, and create affect for instructors and courses. Implications and future research are also discussed.
