This course develops the student's communication skills in grammar, writing, reading, and formal registers of speaking, into an advanced level. It caters to the students who have completed the intermediate high level: ARA300, or whose language assessment reflects an intermediate level of proficiency of Arabic as a heritage language. The teaching of this course will also focus on error analysis to develop the student’s ability to distinguish between their version of heritage spoken language and that of the erudite Arabic, الفُصْحى, as used formally across the Arab world. By the end of the course, the student will be able to write in a formal academic register, sustain oral expressions and deliver oral presentations in formal Arabic.
