Moodle offers a flexible quiz builder. Each question is a full-featured web page that can include any valid HTML code. This means a question can include text, images, sound files, movie files, and anything else you can put on a web page.
In most instructor-led courses, a quiz or test is a major event. Handing out the quizzes, stopping class to take them, and grading them can take a lot of the teacher's time. In Moodle, creating, taking, and grading quizzes is much faster. This means that you can use quizzes liberally throughout your courses. For example, you can:
Use a short quiz after each reading assignment to ensure the students completed the reading. Shuffle the questions and answers to prevent sharing among the students, and make the quiz available only for the week or month in which the students are supposed to complete the reading.
Use a quiz as a practice test. Allow several attempts, and/or use the adaptive mode to allow students to attempt a question until they get it right...
