Regarding the face to face lessons; I use a board and paper.
I will be monitoring the progress of the student and depending on that I will move forward with him/ her to the next level.
In the online courses, I use Microsoft word and excel and connect with the student via zoom application so everything can be read, heard and written properly as I don't provide any pre-recorded sessions or classes.
I will be with the student during the hour and after the class (online or face to face) I make a revision of what was taught in that class and give a homework to be accomplished before the next class, so I know how is the progression of the student going.
After four classes (depending on the student's level) I make a test with everything that was taught in the last classes, and if there is any weakness noticed, we cab focus more on them.
My experience for two years face to face and two years of online classes will be used perfectly to help who is willing to learn Arabic in reading, talking, communicating and writing.
