In this paper, we outline a solution to the problem that teachers for students in heterogeneous EFL classrooms need to provide lessons that enable language acquisition at different levels (here: stages of the PT Hierarchy). Therefore, we describe a learner- and learning-centred application of… read more
This chapter introduces one of the key applications of Processability Theory. Diagnosing L2 development is equally important for SLA research and for language teaching. We will provide an overview of profile analyses and describe Rapid Profile, a diagnostic tool based on PT, offers a quick, valid… read more
In this chapter one of the key components of Processability Theory for classroom applications is introduced: Teaching a foreign language is constrained by the PT hierarchy. This has been known as the “Teachability Hypothesis” introduced by Pienemann in 1984. This chapter summarizes the Teachability… read more
The objective of this chapter is to explain learner variation as described in Chapter 2 using the processability framework outlined in Chapters 3 and 4. We will focus on two aspects: (1) the limited structural range within which interlanguage variation occurs and (2) the steadiness of learner… read more
