This center offers classes in Algerian Arabic and Modern Standard Arabic. The Algerian Arabic classes follow an unusual method in which students memorize a series of dialogues of progressively increasing difficulty. While the language in the dialogues is sometimes a bit outdated, the 45-lesson course gives more than enough material to allow you to become basically competent in Algerian in day-to-day situations. The dialogues also convey considerable amounts of cultural information. The main disadvantage of this method is that students are given very little opportunity to practice speaking Algerian themselves (instead just repeating from the dialogues), meaning that you do not develop confidence speaking from the class. The teachers are excellent. The MSA classes use the method from the INALCO in Paris. I did not take these classes but heard good things about them.
There are intensive sessions offered in June (I think?) and September. Outside of that, group classes are only available if there is another student at the same level as you, which is often not the case.
