Duolingo.com is a language learning website where people can learn language. It is totally free. It is a helpful app to practice language skills but probably not appropriate as the only or primary source of learning a new language, especially for language that have very different sentence construction pattern.

The objective of this website is giving a chance to the people of all around the world to practice and to lean foreign languages staying at home. It is not needed to go to any institution to practice or to learn. There are many language clubs in this website where people can be a member of any club. It helps them to practice in a group.

This website gives the learners an opportunity to learn a foreign language in a fun and rewarding way. It is a game like application. It is not particularly challenging as many of the questions are effectively multiple choice. The game based design encourages daily use. Users can re-visit any section that they desire how many times that they want. The users interface is flawless. The only downfall is the ads, but that is understandable for a free app that must make money somehow.  Later, I also found a version which is without ads.

The website is less concerned with teaching grammar to the users and more focused on vocabulary. By repetition and recycling of vocabulary, it gives users a chance to memorize without drilling.   

This website is helpful for the people who want to brush up their foreign languages which they are getting to forget and confused. 

The motivation system of the app is too poor in my sense. Only ‘congratulation!’ is not enough and appropriate for all the learners. There may have some more words and phrases for motivation which could be used according to the level of performance of the user.

Though primarily it is a helpful website still there are a number of limitations. It does not start from the basic level. It starts from word level but does not teach alphabets of the language. Another thing is the content within a given language does not go far enough. That is, it will get a user to an intermediate level but cannot get the user to an advanced level in the language. There may have some advance courses for each language. The speech element works intermittently. Going from one level to the next level is not smooth enough. After every level there ae some offers to get bonus points or to make the points double. It is good for some users I think but the people who do not want to waste time by doing those level cannot avoid it easily. After skipping those offers, the app needs to be restated to go to the next level.

It is necessary to choose a language to start a course. After choosing a language course get started. But there is no option no go back and choose another language as far as I explored.

The home page is not containing enough information which may help the users. There is no way to test up to higher level or even submit feedback or help request or these options ae so hidden as to make them unavailable. The website teaches using quizzes. New material is introduced in the quizzes when the user does not know the answer. People ae guessing what is the correct answer. They make it wrong and then it gives the correct answer. The courses are completely example driven. There is no explanation. This website, to me, seems very useful for e-learning and practicing language that has already been studied. But it is not suitable for the beginners. I faced difficulty in learning completely foreign language with this app due to lack of explanation. There is no explanation of grammatical structure. Some words have more than one meaning and those are not explained.

While exploring, I was having a really hard time trying to figure out how each word is pronounced. There is no option of checking my own pronunciation. In my opinion, language learning should be through verbal interaction, which is not possible in this website. It only teaches me the pattern of word but I am not able to pronounce it which is the first and foremost use of a language. My improvement by exploring this website is, I can guess, I can match words but I cannot speak or write. The objective of language is to communicate but this website does not make me able to communicate through the language.

The main goal of learning a foreign language is to speak in that language. there is no speaking activity from the very primary level. So sounds are very difficult to utter and to remember for me. If pronounce the word as it spelt, it becomes awful. Because it is not even near to the exact pronunciation.  

Another thing is, all the instructions are in English. So, this app is only helpful for the people who know English. For the rest, this app is not going to help anymore.  

Once it sent me back after I had gone so far. There are too many levels in one category. It is tedious.

If the courses begin with the very basic level like sounds and alphabets, that would be better. There should have enough explanations for new words, grammars, sentence structures and so on. Levels can be educed in every category. There may have some more motivational phrase to motivate learners effectively. Motivation is really very important in learning a new language. There should have a system of recording the users voice to match it with the exact pronunciation which is given into the website.

Most people like me are not interested to learn how to read or write the language first but how to speak the language. It would be a lot better if the website focused more on how to speak rather than how to write or read it.

Language learning website is really a great idea for the modern people who are too much busy. It can help people a lot if necessary improvements are done.
