Improvisation by the teacher, both within and outside the lesson plan, are part of responding to the unpredictable learning moves of the student. It is a necessary quality in everyday mainstream teaching, in the application of differentiation, in ways that may not start with planning, such as Dogme, drama, Silent Way, and also in the process of demanding high.
This article by Adrian examines some of the issues of meeting the unpredictable in the classroom, and especially at how teacher training might take the unpredictable into account.

Just like to say that the IATEFL workshop you delivered on this subject was great. I have written a brief write up on it from my hastily scribbled notes https://angloteachers.wordpress.com/2015/04/18/arian-underhill-on-jazz-not-pron/ but was hoping to be able to link to all those lovely questions you put up during the session.
Hello, Mr. Underhill. I was looking forward to read the article but found out it seems it’s been removed. Is there any other place where I can get access to it? Thanks a lot in advance!
Hello Sergio,
Adrian’s article was published in The European Journal of Applied Linguistics and TEFL, Vol. 3, No. 2, 2014. pp. 59 – 69. Maybe you can access it through your nearest library.
Best, James
