Hotpot module
From MoodleDocs
The Hotpot module allows teachers to administer Hot Potatoes and TexToys quizzes via Moodle. The quizzes are created on the teacher's computer and then uploaded to the Moodle course. After students have attempted the quizzes, a number of reports are available which show how individual questions were answered and some statistical trends in the scores.
Note for administrators: The hotpot module is disabled by default in Moodle 1.5 and 1.6. It may be enabled via Adminstration >> Configuration >> Modules.
