Larsen-Freeman mostly researches second language acquisition. She also studies English grammar. She thinks grammar is not only a set of structural patterns, but also important for making meaning and for changing language to meet a communicative context. She thinks that complexity theory is a new and useful way to understand language, its acquisition, and its use. She sees all three as complex changing processes that do not move neatly in a straight line. She applied this idea to teaching grammar, or “grammaring” as she calls it. The dynamic approach to second language development includes the idea that students each have their own path to learning, and that teaching is fundamentally a process of managing learning.
