Todays, using new teaching methods for learning is very important and these methods can make the work easier for students.

Leitner 504 is an application that teaches you the words of the 504 book in the form of a Leitner box.

This application includes all words, pronunciation, meaning, definition and examples.

One of the most effective ways to learn is to use the Leitner box properly. In fact, it is a method that transfers information from short-term memory to long-term memory.

The way this application works is that you enter the words of the book in the box to  learn completely, and after a while the words are exiting the box and the words are transferred to long-term memory.

You do not transfer the cards to the box  directly., first you should  Study Lessons ; then  Review Cards . and you should guess the meaning of word only. Correct or Incorrect.

In the Analyze Statistics , you can analyze your learning process.

Sources of this application is 504 Absolutely Essential Words. The meaning of words are translated by Developer.
