Create Cloze activities
While Cloze activities are not suitable for every occasion, sometimes it can be just what you are looking for.
The interface is not pretty, but it works! Lextutor allows you to input a text block, and generate a cloze activity with drop down menus to make your choices. The test is "self-correcting" and pages you create are given a URL that will persist for as long as the page is accessed (minimum one year.)
Take any text, mark the words you want to learn and learnclick.com transforms your text into a cloze deletion test.
