Learn it fast. Know it forever.
Rosetta Stone has often likened their learning process to the way we learned our first language, as children. To that end, their immersive approach to presenting learning material utilizes activities such as picture association.
However, adults are not children. Noticing and testing observed patterns is time-consuming, and can easily lead to unresolved ambiguity and frustration. Children's minds are, in some ways, more receptive and have lots of time to notice and test patterns. On the other hand, adults have other powerful capabilities that they can and should bring to bear to learn language more quickly and reliably. To approach language learning with limited time and to restrict one's self to toddler-friendly methods appears to be the worst of both worlds.
Transparent Language Online is designed to help the learner build a large vocabulary of words and phrases that are easily recalled and retained in long-term memory, but in much less time and with more certainty and reliability. Transparent Language's "Declarative First" method uses a "paired language" approach that presents the target language alongside the learner's native language, reducing ambiguity and increasing the amount of material learned per hour of time spent. Children learning a first language don't have this option, but fortunately adults learning a second language do.
With paired language and the Declarative First method, users will learn faster, with less ambiguity, longer retention, and less potential for frustration.
