Understanding mastery
Lexorium tracks how well you perform on different skills for each card. Recommended practice uses that information to choose the next kind of task.
This page explains the learning model. For how to run a session, see Start a review.
Skills
Skills you may see in Analytics and Practice include:
| Skill | Typical game |
|---|---|
| Recognition | Matching (word → meaning) |
| Reverse recognition | Reverse Matching (meaning → word) |
| Free recall | Typing |
| Context | Context Detective or Cloze |
| Discrimination | Contrast |
| Lemma recognition | Lemma Hunt (Latin) |
| Morphology | Declensions (Latin) |
| Translation | Translate |
| Grammar | Grammar (lobby games only) |
| Pairing | Concentration (lobby games only) |
Not every skill is available for every card. Latin lemma and morphology tasks need paradigm data on the card. Context tasks need a usable context sentence. Translation is for non-English cards.
How Practice chooses a task
For each card in a Recommended practice session, Lexorium:
- Lists skills you are eligible for on that card.
- Prefers skills whose mastery is still below a soft target (about three-quarters of the way to “strong”).
- Among those, picks a weaker skill so you strengthen what you have not mastered yet.
- Falls back to a basic recognition task if nothing else qualifies.
Lobby Concentration and Grammar track their own skills but are not part of the adaptive Practice ladder.
What changes mastery
- Correct answers raise mastery for that skill.
- Incorrect answers lower it.
- Hints, slow answers, and highly supportive sentence context raise mastery less on a success.
- Lexorium also watches how many attempts you need for each word and adjusts later practice from that history — not from an ability quiz.
Mastery does not replace scheduling. A card can be due soon while one skill is still weak — Practice may then test that weaker skill when the card appears.
