A Method for Normalizing Students Scores Case Study Faculty of Information Technology At Al-Ahliyya Amman University
Assessment and evaluation of students in a percentage based grade system is proven to be unfair, biased and in many cases lead to
unrealistic evaluations, and unreasonable results. This is basically due to lack of understanding by instructors, who act just as a
calculator without any considerations to any measures or rules; i.e. they just add up to totals of exams and assignments given to their
students, no adjustments are done, and when done, they are not fair. Unfairness comes from adjusting all grades by an x amount of
marks that are either added (to raise the grades) or deducted (to lower the grades). In this paper we are proposing a system that is based
on a mathematical approach for adjustments of grades based on criteria that we will prove to be sound, efficient and fair to all students in
any course at Amman University, with an instructor based on their performance and compared to the rest of the students in the specific
