Multiple choice (several answers)
Students tick every option they think is right. Use it when more than one answer is correct, so that each option has to be judged on its own.
When to use it
Use it when several answers belong together: which words are verbs, which animals are mammals, which statements are true. A student cannot get it right by spotting the one best option; they have to decide about every option separately.
It also works with only one correct option: a student who does not know how many answers are right has to think about each one.
Setting it up
In a worksheet, use the + between two items and choose Question.
If the question is not already open, click its pencil, and write the question at the top.
Click Add an answer option for each option and type its text.
Tick the box at the start of every correct option.
Click the tick when you are done.
As soon as two options are ticked, the question switches to Multiple choice (several answers) by itself. Allow multiple answers is then switched on and locked, with the note that it is required when two or more correct answers are marked.
To let students tick several options when only one is right, tick Allow multiple answers yourself.
What students do
Students click the options to tick them, click again to untick, and send their choice with Submit. They have to tick at least one option before they can submit.
If the presentation has Show correct answers turned on, each option they ticked turns green or red after they submit. A correct option they missed is not highlighted.
Checking the answers
The answer is checked automatically and counts only when it matches exactly: every correct option ticked and no wrong one. One missing or one extra option makes the whole answer wrong; there are no partial points.
In the presentation, click Results on the question to see what each student ticked. The marks also appear in the grading screen.
Tips
Always include at least one wrong option, or students can simply tick everything.
Keep the list short. With no partial points, a long list makes the question very hard to get fully right.
Students are not shown the correct option they missed, so go through the answers together afterwards.
