The typical claim is that teachers cite Krashen—and only Krashen—when talking about, or defending, comprehension-based teaching practices. In the past decade or so, that’s also expanded to include Bill VanPatten. One reason teachers might do this is that they have day jobs, and that day job certainly isn’t researching Second Language Acquisition (SLA) theories. Seriously. The fact that anyone demands evidence from comprehension-based teachers to justify their practices is insulting. Furthermore, the fact that language teachers have *any* awareness of research is amazing when you compare the state of teacher preparation programs/licensing paths with the responsibilities of a classroom teacher. Sometimes I think how INSANE it is that I even blog about teaching in addition to teaching!
Now, time—alone—doesn’t invalidate research, but bad research certainly invalidates bad research. When it comes to science, Krashen hasn’t been all that technical, but you know what? Who cares?! Eric Herman brought up that bad research could have very good implications for teaching, while at the same time good research could have very bad implications for teaching. His example was that if it were replicated study after study that 100% error-correction all the time were effective, just imagine a classroom in which the teacher corrected every utterance/writing of the students! That’d be a messed up, top-down, authoritarian, walking-on-eggshells kind of class for most kids in the room.Continue reading
