Khaled Hassan Software Engineer - Ex Teaching Assistant
No reviews yet

I have been working as a teaching assistant at The British University in Egypt, delivering sessions in English for students up to senior years. Also, I have been mentoring an undergrad student who is currently studying in Germany and we made a good progress through online communication.

I am open to teach coding for kids, schoolers & undergrads. Also, I am open to help with assignments by viewing them, discussing them with the student, teach him the requirements & guide him until he can successfully complete it. But I totally reject plain requests for solving the assignments on behalf of the student or to just spoon-feeding him the answer without teaching him.

Usually when I teach, I love using visual aids (like white board, collaborative room on the internet for pair programming or sharing my screen) to make sure the student sees for himself what I have in mind and help me draw the picture too isntead of just listening to plain words.

Moreover, I like to deliver the information on 2 stages: first stage is to state the complete flow of the program in English, secondly to translate that flow from English to Coding. Mostly I like to represent what we have to do in Coding to a real-life example so the student can relate quickly and feel that "it clicks!".

Lastly, It is important for me to teach the student HOW he can use what he learned, not just WHAT to learn. In other words, I like to make him realise how he can use HashMaps to improve an existing problem in a system that we may encounter rather than just explaining to him what HashMaps are without applying that knowledge.
