Hi! My name is James Rogers. Im a university professor with over 10 years teaching experience, and have used my PhD research and discoveries made by my over 30 member research team to provide learners with resources to help make language learning more efficient. I hope that you find them useful on your journey learning a foreign language.This app teaches Chinese learners 500 useful idiomatic phrases of English. It contains over 20,000 words of content. It is a textbook written by myself and translator Jingting Gu, and is a collaboration with the best-selling app Flashcards Deluxe. This app contains 500 idioms, an explanation of them in English and Chinese, an example sentence, fill-in-the-blank questions for each sentence, and pronunciation for all English contents. Also included is a custom quiz function which you can use and send your results to your teacher with via email. This app also automatically sends all items you miss often to a special tough item folder to make it easy for you to concentrate on them. Whats more is it features one of the most advanced Leitner algorithms on the market to help you learn more efficiently: you mark items you dont know wrong and they come back more often, giving you the necessary exposure to master them. Items you mark correct dont come back as often, so you dont have to waste your time with items you already know. This method is proven by linguistics research to be the most ideal way to learn. We hope our app helps you improve your English!
