Writing challenge. Day 3. Hello! Today I am going to tell you about the modern way of studying vocabulary using the spaced repetition technique. As I told earlier flashcards are effective, but have some inconveniences in using. You need to prepare them manually, sort them manually, work with them manually and decks with the cards could occupy a lot of space. All these disadvantages could be removed by using an electronic version of this technique. Actually, there are a lot of different resources that can propose you such functionality. You could find different websites on the internet, apps in Play or App Store, special software for PC or Mac. But I would like to recommend the most effective app that I have ever met in that area. It's Anki. https://apps.ankiweb.net/ It's a free and open-source spaced repetition flashcard program. Anki has versions for almost every platform and you could synchronize your decks between your gadgets whenever you want. If one wishes to improve one's vocabulary, one could do it with Anki software. Anki could be readily used on a smartphone, a tablet or on any device that has web-browser. Anki has a big community. It's possible to download decks that were made by other people. For example, it could be a deck with the most frequent words or a deck with the words for a special theme. Anki could be used not only for vocabulary learning. You could use it for learning everything. Anything that has question and answer could be placed on a card and learn with Anki. Anki is a very flexible software. It has so big functionality so it's easy to get started with but difficult to master. I have been using Anki for 3 years and strongly recommend you try it. If you have any questions regarding it, I would be pleased to answer.
