Assistant/Associate Professor of Physical or Organic Chemistry and building materials (Portland Cement).

Methodology

My teaching methods based on
1. motivation of the students to prepare the subject before my explanation to take an overview about the subject then when i explain, it will be more easier for them to understand very well.
2. Using of practical method beside the theoretical due to my experience in the cement industry that belong to my qualifications either Master or Doctorate degrees.
