Spaced Repetition Help Needed!

I like that the new Crown system. Does anybody have any personal philosophies (or anything based on research) that could be applied to this for my classes? What I'm looking for, is a time frame that a student should wait until I assign them the next Crown for a skill already completed. Thanks in advance for any ideas/help!

Revision only works if it's spread out over time. If your students get a skill all the way to level five in a couple of days, they'll have forgotten more than half of it by the end of the month.

The best way to time your revision is with a spaced repetition approach. Duolingo commissioned some research on this, which you can read at ai.duolingo.com. This is something of a good news / bad news scenario:

  • Good news: Duolingo records and calculates a "strength" value for each word you study, so as to calculate when it'll be most effective to revisit a skill.
  • Bad news: For some peculiar reason, Duolingo has chosen to stop displaying this information.
  • Good news: Someone else has made a website to display that information: duome.eu. Here's your page: https://duome.eu/iceman0426/progress.

If your students keep all of their skills at full strength, you'll find it works really well. That's what will limit the new skills your kids can do - sometimes they'll need all of their time for revision, sometimes there'll be some time available for new skills. They'll need your guidance on when to take on new material, and when to consolidate for a while.

Duolingo takes account of how long it takes you to answer the question, and it takes account of whether or not you "peek" - whether or not you hold the mouse over a word to see what it means. When your students can answer the questions quickly and without peeking, the words will decay more slowly.

After they've strengthened the skills a few times, the skills will start decaying more slowly.

1) Duolingo's advice:

2) My advice to individual students:

Some background information about "Duolingo's Crown method

The advice in the English Duolingo Help Center

you don’t have to get to Level 5 right away!

We in fact recommend you don’t get to Level 5 all in one go.

Level 5 is there to show that you have practiced the words in that skill a ton and probably don’t need further practice on it for quite a while. It’s completely optional.

We definitely think we can do a better job of encouraging you not to binge on one skill, though, since that can feel really repetitive.

How can you make the program add new material?

  • Tap on a new skill in "crown level" 0 (purple circle)
  • do all the lessons in that skill until the skill has reached "crown level" 1 (blue circle)
  • tap the next new skill in "crown level" 0 (purple circle)
  • etc. etc.

When are you going to do lessons in skills with "crown level" 1-4?
