Mr. Hallak taught Arabic at Concordia University, Montreal, Canada from 2001 till now. He taught Arabic as well in many other institutes and associations. His Arabic program "Al Ddad" becomes a separate module embedded in the program of many institutions that teach Arabic language.  Internet allowed also students from 19 countries around the world to benefit from this program.

The used method has the core of the traditional method of teaching Arabic, benefits from the researches done in many universities that teach Arabic around the world, and present Arabic in a modern fashion using the latest technologies.  

Mr. Hallak invented the concept of "Visual Arabic ©" on the same example of visual programming computer languages.  Understanding Arabic becomes an easy process independent from vocabularies and other obstacles that limit the understanding of the student.

One of the most important aspects in this method is to build the intuition or the natural disposition (Saliqa) inside those who are learning Arabic. This way the student will not feel exhausted with the learning process.  The topics are organized in logical order to keep the student always in the comfort zone. The number of words given to students in each level is calculated well to have increasing vocabularies along their study and to insure that each student is capable to manage alone after finishing the study.
