28. Major Challenge – Accuracy
A generation been trained with partial credits…… what will happen?
Consider the following scenario:
If you did 2/3 right (or 1/3 wrong) in an class assignment.
After getting the assignment back, you tried to correct it, and did 2/3 right (or 1/3 wrong) of the correction part.
After getting the assignment back again, you tried to correct it, and did 2/3 right (or 1/3 wrong) of the correction part.
Assume this process continues forever….
If fixing 1/3 of the errors means spending 1/3 of time on the assignment, what does this imply?

29. Major Challenge – Accuracy
A generation been trained with partial credits…… what will happen?
Consider the following scenario:
S = 1/3 + (1/3)2 + (1/3)3 + (1/3)4 + (1/3)5 + ……
3S = 1 + 1/3 + (1/3)2 + (1/3)3 + (1/3)4 + (1/3)5 + ……
2S = 1
S = ½
It means that you will spend 50% more time (money, human resource, etc.) to finish your assignment.
