I was taught to ask an open-ended question and then stay quiet.

The answer can either be a close ended answer, like yes or no, or be an answer to an open-ended question.

Texts can range from a single-word response to an open-ended question or as complex as a body of thousands of pages.

In open-ended question formation, 11.5% of subjects recalled the false event suggested by observers.

This means exams with extended writing in most subjects; more open-ended questions and fewer short answers; and better links between different elements of the course.
