Revita — Frequently Asked Questions
You can use Revita in "guest" mode, without registering. However, if you register, Revita can offer you important features, such as:
Note, when you register, you create a user name, by which other users can see you in the system. Your email address is used for registration only, and is not published or revealed in any way — it is completely safe.
All stories you upload to your private library are visible only to you. There is no way anyone else can look inside your private library.
You can now share stories with your friends — you can choose a particular story and send it to a friend; if the friend accepts it, it will appear in her own private library.
You share any story you like with your friends:
Ревита анализирует каждый тескт, разбивает его на кусочки (примерно 2-3 предложения), и для каждого кусочка создает упражнения, настроенные на уровень ученика:
1. Все фразы и слова в тексте связаны с лингвистическими конструктами, которые ученик должен усвоить. Схему конструктов можно увидеть в настройках, нажав "Настройки" ⇒ "Настройки обучения". Конструкты могут быть включены / отключены в ручном режиме, или (более рекоммендуемо) оставить все конструкты включенными, и предоставить Ревите возможность выбирать подходящие конструкты в соответствии с уровнем знаний ученика.
Уровень ученика оценивается на основе всех предыдущих ответов на упражнения — какие конструкты для ученика проще, какие сложнее.
2. Ревита старается подбирать упражнения, в среднем подходящие для ученика по уровню:
Поэтому очень важно, чтобы уровень упражнений оптимально соответствовал уровню ученика в среднем — т.е. ученик может получать очень сложные или очень простые упражнения, но это случается редко.
3. Упражнения выбираются из текста случайным образом, так что при каждом прохождении текста, уражнения будут новыми — это позволяет многократно упражняться с одним и тем же текстом, и делает упражнения более разнообразными и менее скучными.
For each story, Revita tries to estimate its level of difficulty. The difficulty depends on many factors: on the levels of difficulty of the concepts found in the story, on how difficult/rare the words in the story are, etc. The story''s rating is used in computing the learner's rating, explained in part here.
In the library, the difficulty is marked by one to three stars.
Revita creates Flashcards for you when you are reading or practicing with a story: any time when you see an unfamiliar word, you can click on it — that will display the word's translation (in a language of your choice), and will also add that word to your deck of flashcards. The flashcard will contain 3 things:
You can review your vocabulary in the "Flashcard" exercises. If you don't remember the word, you can ask to look at hints. You can practice with your vocabulary
You can add new flashcards, edit any flashcard in your deck, and delete any flashcards you don't like / need.
Flashcards track how difficult you find words in the vocabulary. Easier words — whose meaning you know most of the time — have greener color, and more difficult words — which are harder to remember — have redder color, and words in between are yellowish.
The color tells "how well" you have mastered this word so far. Cards are shown in random order which is based on the spaced repetition algorithm to use the psychological spacing effect.
Blue cards are special —
Groups in Revita are created by teachers — at a school, a university, private tutors, etc. A teacher can add her students (and additional teachers) to a group. The main purpose of a group is:
Optional: The teacher can also control the learning settings for all stories in a group — which exercises are enabled. The teacher can also enable Tests — for a fixed period of time — for some languages.
Groups are organized by the teacher. The teacher invites the students to join the group by
The teacher can create any number of groups for students. To create a group:
After the group is created, the Group Library will appear. The teacher can share any story from her own private library to the library of her group.
The teacher can follow the performance of the students in the Group by going to the Analytics tab.
The rating is based on the Élő formlula — it is the method used to rate players in chess and in many on-line games — except here the "players" are the learner and the exercises. Each exercise has a difficulty level, which is its own "rating".
The Élő rating in Revita means approximately as in chess:
The Élő formula updates the rating after every exercise (every "match") as follows:
|learner rating||exercise difficulty||answer correct?||effect on score|
|low||high||-||small (or no) drop|
|high||low||+||small (or no) increase|
The idea is that the increase or loss reflects the expectation or surprise — a low-rated player is expected to answer a difficult question wrong, but it is a big surprise if she answers a difficult question correctly! So your rating changes depending two things: your current rating and the difficulty of each exercise. For more details, please read about the Élő formula (e.g., in Wikipedia).
Based on your rating, Revita also tries to estimate your CEFR level — a rating around 1000 is near A1, rating over 2200 is C2, and the rest are in between. These estimates are approximate, and will be improved over time.
