This means that nearly two out of five learners increased their ACTFL score by at least two sublevels after as little as two hours of study, a performance increase that is unmatched in the language app space. Based on these predictions, the researchers estimated that 74% of participants increased their ACTFL score by at least one sublevel, and 39% increased their ACTFL score by at least two sublevels. The TrueNorth Test can be used to predict language performance according to international language proficiency standards, like the scale established by the American Council on the Teaching of Foreign Languages (ACTFL).
What does this mean in terms of language proficiency standards, like ACTFL? Among learners who studied at least one hour per week, 85% of them improved their oral proficiency score. With as little as two hours of practice over two months, 82% of learners improved their WebCAPE score and 77% of learners improved their oral proficiency score. Let’s take a look at what the researchers found. Higher scores on the post tests would show just how much users learned from Mango. They then studied exclusively with Mango for two months and took the same tests again. The learners in this study took two standard language proficiency tests - the WebCAPE college placement test, which assesses reading, vocabulary, and grammar, and the TrueNorth oral proficiency test, which assesses speaking and oral comprehension skills. In 2019, an independent research study conducted by scientists from Queens College in New York and the University of South Carolina examined the efficacy of Mango Conversations, Mango’s flagship language-learning program. But why stop there? We know what learners should be learning, and what they think they are learning, but we wanted to know what they are actually learning from Mango.
Our customer satisfaction tells a similar story - stellar customer reviews and high renewal rates show us that our users think that Mango is helping them learn languages. With insights from the latest research in Second Language Acquisition, our courses are designed to effectively teach learners to start (and continue) the conversation in over 70 languages. At Mango, we have confidence in our methodology.
