ClozeFox: Gap Exercise Generator with Scalable Intelligence for Mozilla Firefox

Description

We propose a Firefox extension for language learning purposes which will generate fill-in and multiple choice exercises (cloze tests) from authentic pages on the Web. Any language learner worldwide will be able to turn any authentic text into an interactive exercise on the fly by clicking the ClozeFox Extension Button. Language teachers will be able to simply direct their students to a web page and students will have the authentic web page rendered as a fill in exercise thanks to this Firefox extension.

Operation

ClozeFox first checks the page on the amount of usable and useful text, text structure and language ID based on page info or on trigrammes. It then makes a frequency list of the words in the text.

The ClozeFox generator hides words on the basis of a routine with scalable intelligence: as a simple random routine would not be interesting from a linguistic-didactic point of view, ClozeFox will select gaps according to frequency level, word category, and later on semantic field, contrastive-linguistic aspect in order to turn the exercise into a rich learning experience.

ClozeFox generates fill-in exercises (for complete words or word-parts on morphological level such as word endings) and multiple-choice exercises (with other words in the text as generated distractors).

The ClozeFox options menu (with ‘remembered’ options) will include:

  • Number of gaps
  • Min/max length of gap
  • Per word category: nouns, prepositions, verbs ?
  • Exercise type: written (with option whole word / partial word)
    and multiple choice (with option number of distractors)
  • Time limitation
  • Send exercise to … (completed to show to parents/teachers what
    you have done as a learner; or ’empty’ to send it as a teacher to your
    student or as a students to your co-students)

ClozeFox as an application is highly scalable on the following levels:

  • The complexity of the routine for selecting gaps.
  • The intuitive intelligence of the system to adapt to the user
    based on learner behavior, performance and errors.
  • The possibility to add a refined morphological analyzer and parser later on.
  • The possibility to ask for pronunciation (through sound
    synthesis) or translation of the word to fill in or any word in
    context.
  • Turn ClozeFox into a real collaborative Web 2.0 social exercise generator:
    • Students will become able to exchange self-made exercises,
      store them in social collaborative repositories, teachers can
      ask them to do so and monitor progress.
    • Language teachers worldwide are expected to encourage to
      use Mozilla Firefox in order to enrich their own learning
      environment with a powerful tool for autonomous and/or
      collaborative learning.

ClozeFox can be seen as a first product in a series of tools for enhancing the (language) learning experience.

Mockups

Below are the sample screens to give an idea about our Firefox extension. Please click on the images to view them in their original sizes.

    This is absolutely brilliant. Will the distractors be generated automatically? I assume so but you didn’t mention this above. The key, in part, to making this work on a continuing basis is the ability to find “good” distractors that didn’t follow a pattern that students could intuit over time.

    Finally this would be an even more revolutionary project if you could analyze each page as to the percentage fit to various levels of publicly available frequency lists. That simple statistic would help teachers like me QUICKLY evaluate the usefulness of certain pages.

    Michael,

    Yes, in a sense, everything will be automated as much as possible. And thank you very much for the feedback on using the publicly available frequency lists. Maybe we’ll be able to put a little indicator that shows how suitable the current page is for automatically converting it to a cloze test.

    Now we’re waiting for the preliminary results to be announced on 4th of December. If we are elected we’ll start to work on this tool.
