Instruction about teaching business communication skills has been a long-established tradition in the communication discipline. Recent trends in teaching communication training and development extend a long-held emphasis on business communication skill instruction. Given the classical roots of the communication discipline and the current focus on communication skill instruction, this article suggests that future communication theory and research should focus greater attention on behavioral learning outcomes--specifically communication training. This review identifies relevant communication theory that informs a renewed research agenda focused on enhancing behavioral learning outcomes. In proposing this research agenda, we discuss opportunities to apply our current knowledge of intrapersonal, interpersonal, group, public, organizational, mediated, and intercultural communication to advance the discipline through theoretically driven research about business communication skills.
