Study when and where you always would like, whether at home, in the train or during a break with your mobile telephone and lessons of your own at arbitrary places and at every time. For studying you need only your mobile phone and your lessons in the MM3-TeachingMachine. You design your learning process effectively and highly efficient with a minimal time expenditure. You build up your personal knowledge at the same time. The MM3-TeachingMachine is optimized for learning with the mobile telephone, e.g. as your vocabulary trainer. Only few intuitive inputs for the operation are necessary. - No inputs are necessary in the learning mode for remembering facts at all. You can fully concentrate on studying. - The MM3-TeachingMachine organizes 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 remembering 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 coach is known for learning a foreign language. The principle, however, isn't limited to vocabulary. You can effectively learn 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 remember 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 and your studying progress is stored in both directions. The reversal of question and answer supports your learning process.
