This is a full fledged online course in Arabic by the UC Consortium for Language Learning and Teaching that is designed around two textbooks with accompanying DVDs: Alif Baa: Introduction to Arabic Sounds and Letters and Al-Kitaab Fii Ta’allum Al-’arabiyya Part 1 by Kristen Brustad, Mahmoud Al-Batal and Abbas Al-Tonsi. Its program includes sections on:
- Alphabet
- Vocabulary and Phrases
- Grammar
- Culture
- Listening and Speaking
- Quizzes
- Typing
I haven’t worked through it yet, but it looks like solid, useful material. It includes some good audio materials.
