Regular expression short answer

This question type (for the Moodle quiz module) aims at a more advanced system of student’s response analysis, through the use of regular expresssions. This question type is an extension of the SHORTANSWER type. It can be used on its own and can also be incorporated into the existing Cloze (embedded) question type.
Like the Short Answer question, the RegExp Short Answer question expects the respondent to answer an “open” question with a word or a short phrase. However, the RegExp system system gives you access to a more powerful system for  analyzing the student’s answers  with the aim of  providing more relevant immediate feedback .
