What I’m thinking about is what I might include in an introductory workshop. I’m also thinking about Udemy, and whether to use it fully, partly, or press ahead on my own. But now I’ll confine myself to the first point.
In a workshop, I would probably run the participants through a Heinrich Maneuver. I’d give then a questionnaire to test their left brain right brain balance. I might get them to do a modified Gold List trial, simulate shadowing across a bridge, try a spaced repetition system, show them Lomb’s core list method, and even give them Krashen’s German lesson.
