Kate Kinsella is well-known for her research on helping students learn and use academic vocabulary. The California Department of Education has put a series of her videos and materials on their website.
The videos don’t at all capture her dynamism that you see in person, but downloadable “apply the concepts” materials are worth their weight in gold! And, they’re free.
I’m adding this resource to The Best Websites For Developing Academic English Skills & Vocabulary.
