ABSTRACT
This chapter presents an introduction to differentiated teaching (DT) for instructors of Spanish in heritage language (HL) classes as well as in mixed classes, i.e. classes that enroll HL learners (HLLs) and second language learners (L2Ls). It examines the shortcomings of one-size-fits-all teaching in classes that enroll HLLs. The overarching principles and strategies of DT is presented, followed by a discussion of their application to HL and mixed classes. The chapter details the eight tools of DT, and describes the formative assessment, a key component of DT. The eight tools serve as examples of how teachers can take activities that are low-tech and straightforward and apply them in ways that establish a differentiated classroom and instantiate the principles of DT. In terms of affective issues, flexible grouping can address HLLs' need to socialize with other HLLs in order to deal with the challenges of navigating two cultures and languages, including rejection.
