Gap-fill, Fill in the blank, Cloze, Embedded answers, call them what you like - Moodle's standard Embedded Answers (Cloze) question type is a useful but quite tricky feature to implement. There are various alternatives, such as the contributed Gapfill question type, and the very popular HotPot module , but if you are unable to add plugins or you need to stick with Moodle's default, here is an online Cloze question type generator. You don't need to worry about getting the syntax correct as all you need to remember is to add a hashtag # in front of the word you wish to be left blank. Ah - OK - it's in German -not to worry - it's really simple!
Once you've added in your text (1) and clicked the button to preview it (2), it will appear below for you to check it:
Then when you are happy with it, click the second button from the left at the top of your screen to generate the syntax:
In another tab you'll get your question text - you just then copy it and add it to your Moodle question in your Quiz:
Actually, this generator will do a lot more if you wished to spend the time exploring it and/or if your German or your Google Translate are up to it. For example, the last button on the right at the top displays different characters, numbers, accents and so on that you can include in your question.
However, the title is "Quick ways.." so I'll leave it at that. I know there are other useful methods out there so it would be good if people can suggest some more. (And thanks to the Moodlers over in the German forum for highlighting this one.)
