Instructional designers (IDs) wear many hats, one of which is to be an effective collaborator with subject matter experts (SMEs). The SMEs and IDs share the common goal of providing efficient and excellent instruction to students that meets stated outcomes. Despite this shared goal, consultation and the subsequent working relationship between IDs and SMEs may still be fraught due to the power dynamics, institution pressures, and individual insecurities that can impact the communication and collaboration between the parties. This capstone begins the process of creating an online training course on the use of motivational interviewing (MI), a method of counseling used primarily in the health sciences, by IDs in their consultations as needed to overcome the resistance of SMEs toward changing aspects of their instruction, thus improving the relationship and likelihood of creating effective instruction. The capstone project was created using the ADDIE conceptual framework and the four-component instructional design (4C/ID) model to guide the analysis and design of an online training in MI for IDs. MI is a method commonly used in mental health environments to help motivate clients to overcome their issues by exploring their challenges in motivation, or ambivalence (Csillik, 2013; Miller, 1983). By applying MI in consultations between IDs and SMEs, the IDs' goal is to help SMEs resolve their internal resistance to instructional change and identify their motivators as they embark on creating effective instruction. MI may prove to be an essential approach for IDs who want to build and maintain a rapport and trust with SMEs, and ultimately create better instruction for students due to a more effective working relationship.
