Only few intuitive inputs for the operation are necessary. - No inputs are necessary in the learning variant for memorizing facts at all. You can fully concentrate on studying. - The MM3-TeachingMachine trains efficiently your studying progress in another learning mode after an optimized system of a studying card index. How it works Studying consists for the most part of memorizing facts. For this the facts must be repeated regularly. For an effective repetition the studying card index is already used for a long time. The studying card index as a vocabulary trainer is known for learning a foreign language. The principle, however, isn't limited to vocabulary. You can effectively train e.g. historical dates, names of persons, financial figures etc. with index cards. The facts are written in the form of questions and answers on cards. On one side of the card a question is written and on the other the corresponding answer. With the help of several boxes in the studying card index you repeat the facts so often until you memorize them. In the MM3-TeachingMachine questions and answers are exchangeable so that you can check your studying progress in two directions. You can question e.g. a vocabulary as well in the mother tongue as in the foreign language. Your studying progress is stored in both directions. The reversal of question and answer supports your learning process.
