This 'work in progress' showcases the methodological processes underway in Phase II of a three-part study. In its entirety, the study aims to (1) critically assess and evaluate the current research-to-practice cycle as it relates to participation and success of African Americans in engineering and computer science, and (2) set a national agenda for broadening the participation of African Americans in these two fields. Phase II of this study consists of semi-structured interviews with approximately 60 subject-matter experts from the fields of K-12 education, undergraduate education, graduate education, and the engineering and computing workforce. This paper discusses the following processes: a) participant recruitment, screening, and selection, as well as, b) protocol development and piloting. Insights about our methodological approaches might be useful to others developing research designs intended to capture the perspectives of various stakeholders associated with similarly complex and multifaceted issues.
