The City University of New York and the University of South Carolina conducted an independent study in which they found that an average of 34 hours of Duolingo was equivalent to a full university semester of language education! That is quite incredible, given that this Android app is available for free (which also means free of advertisements)! However, although the app proves to be great starting point for beginners, someone seeking in-depth knowledge of a language may have to move onto other modes.

What’s Missing in the Duolingo App
While the Duolingo Android App is deserving of all the awards and accolades it has received, there are some shortcomings that must also be kept in mind. The learning of any language is not complete without the four essential skills – Listening, Speaking, Reading and Writing. While you do learn to read to some extent, the bent of the courses is largely towards conversational skills. It is no doubt that diligence with the app will accord you the ability to follow the spoken language and respond adequately, but it does little for achieving proficiency in reading and writing. Related to the same point is the fact that a learner on Duolingo does not inculcate any understanding of grammar, but like a child who learns to speak organically, just the functional usage of the language. Moreover, the mode of teaching deployed by the app is such that there are no instructions given at any stage. While the user interface is self-explanatory, the lack of instructions could throw some people off. In addition to this, the learner has no control over the vocabulary topics, thereby not having the choice to learn words for a specialized domain that s/he intends to deal with. However, notwithstanding these shortcomings, this an excellent platform to start off on the path to learning a new language. Its pedagogic techniques have been proven to be effective for a wide range of learners, which means it is serving its purpose well.Pros
