I’m Keith Folse — teacher, author, world traveler, and lifelong language learner. Through my books, classes, and presentations, I help both teachers and learners of English all over the world.
I’ve written more than 80 books published by National Geographic Learning, University of Michigan Press, Oxford University Press, and Wayzgoose Press. These books cover:
I published my first book when I was 21 years old. Now my books have sold millions of copies and have been translated into four languages and widely used in universities, language programs, and teacher-training courses worldwide.
I also write the Smart Travel Books series, including practical guides on destinations such as seeing the Northern Lights or visiting places like Buenos Aires, Orlando, or London. I love travel, and I want to help make it easier for more people so they can explore the world.
I hold an M.A. and Ph.D. in language education and specialize in clear, research-based teaching methods that work in real classrooms.
I’ve taught languages in both in the U.S. and internationally. I taught English, French, and Spanish in:
I also train teachers to teach languages better. I’ve led teacher-training workshops in more than 30 countries across Africa, Asia, Central America, South America, and Europe.
One reason I’m an effective teacher is that I’m also an experienced language learner. I’ve studied:
These experiences help me understand the challenges students face—and they influence how I write my books. The best teacher is also a student.
When I’m not working with languages, you’ll probably find me:
I’ve flown millions of miles all over the globe. So far, I’ve visited 61 countries, and I hope my books—whether about English or travel—help you discover more of the world, too.
