The mission of "Communication Education" is to publish the best research on communication and learning. Researchers study the communication-learning interface in many ways, but a common approach is to explore how instructor and student communication can lead to better learning outcomes. Although scholars have long classified learning into three domains--cognitive, affective, and behavioral--it is not often that behavioral learning is investigated in instructional communication research. Thus, the focus of most of the research in instructional communication is on cognitive and affective learning. This forum explores the study of affective learning by addressing two critical questions that define the field's exploration of the topic: (1) What is affective learning?; and (2) How should we measure affective learning in instructional communication research? This forum initiates conversation on this topic. The essay presented is one of seven in this forum on the topic of affective learning. The author was introduced to affective learning by his graduate advisor and mentor, Lawrence Wheeless. In subsequent decades, instructional communication theory and methods have evolved considerably, and today the author welcomes the challenge presented by this forum to turn a thoughtful and discerning eye on the construct of affective learning. This forum has given the author the opportunity to think in new ways about his own teaching philosophy, pedagogical methods, and the impact he is having on his students.
