Service-learning (SL) is a relatively new pedagogical approach to facilitate student learning at the university level.In SL, students enrolled in an academic course provide a needed service to a community partner. Through guided reflection, students link classroom-based, theoretical knowledge with clinical applications. Students' active engagement in learning facilitates thinking critically, questioning assumptions, considering varying perspectives, and appreciating the civic purpose of their profession. This article describes three SL applications, in dysphagia, educational audiology, and augmentative and alternative communication. We explain the rationale for each, along with ways in which to measure the effects of SL on student learning.Although it has been some time since Wendell Johnson first posed his famous three questions, they continue to serve as a valuable guide in thinking critically about an issue. These questions, What do we mean? How do we know? and Is it a difference that makes a difference? are particularly relevant when exploring the contribution of SL to teaching in the discipline of human communication and its disorders. This article focuses on the contribution, and potential contribution, of SL to teaching in three areas: dysphagia, educational audiology, and alternative and augmentative communication. However, we encourage readers to think creatively about how they can apply SL to the many areas within the field of communication sciences and disorders, as well as within other disciplines.
