July 24
On july 24 I conducted achievement test on 9A class on chemical bonding in chemistry.
It was conducted for 1 hr section.
I corrected the answersheet and tabulated the scores. Inorder to identify problem area, I selected the areas that marked very low.
I found electronegativity difference and structure of ionic and covalent bonding as very difficult topic for students.
These are the achievement questions
