In 2017 I wrote, designed, illustrated, layed out, published, and began using my own 70-page textbook for my speaking classes at Fukuoka University. Here is a sample chapter from the second edition, published September 2017. (Pages seem to go out of order when viewed on mobile.) Adapted versions for different types of classes (Listening and Reading, for example) were also produced when needed. Printed versions of Control Words were produced up to Edition 12, in 2023. I'm now distributing the materials in more of a 'handout' form, on-demand, rather than as a complete end-to-end textbook.
