In this lecture, I'd like to share the way we give tasks to students and evaluate their speaking ability. In my experience, it's very important to give well-prepared tasks in speaking lessons. Without tasks and Can-dos, speaking lessons might end up being nothing more than a series of fun experiences and you might not get expected results over a long period. To solve this problem, I have been working on a speaking test named E-CAT (English Conversational Ability Test) as a test designer with a venture company in the US. In this lecture, I'd like to talk about how to incorporate speaking test tasks in our speaking lessons and how to evaluate our students fairly enough to maximize the results.
