Did you know that as well as blocks and activities the Moodle modules and plugins directory also contains extra question types for the quiz? They’re no more difficult to install than any other add-on, and can quickly add an extra dimension to your quizzes. Here are my top 3:
1) Drag and drop ordering (Moodle 1.9 and Moodle 2.0)
Nice variation on the matching answer theme that allows students to drag and drop their answers.
2) Formulas (Moodle 1.9)
One for the maths departments… Create formula based questions with multiple answers, random numbers, etc.
3) Image Edit (Moodle 1.9)
This is an extension to another nice question type that allows students to submit a file as their answer. The image edit answer type links up with pixlr to provide a completely web based method for students to edit an existing image and submit it. Pixlr has an impressive array of tools, you could set some questions requiring fairly complex graphical work using this. It’d be a great way to test students on the skills required for the iMedia digital graphics unit for example.
