8. The first section provides a summary of how many questions there were, attempts made, and the average score.
9. Following this is a breakdown of the Discrimination and Difficulty of the questions. This is described in the Blackboard manual as follows:
Discrimination: This area shows the number of questions that fall into the Good (greater than 0.3), Fair (between 0.1 and 0.3), and Poor (less than 0.1) categories. A discrimination value is listed as Cannot Calculate when the question’s difficulty is 100% or when all students receive the same score on a question. Questions with discrimination values in the Good and Fair categories are better at differentiating between students with higher and lower levels of knowledge. Questions in the Poor category are recommended for review.
Difficulty: This area shows the number of questions that fall into the Easy (greater than 80%), Medium (between 30% and 80%) and Hard (less than 30%) categories. Difficulty is the percentage of students who answered the question correctly. Questions in the Easy or Hard categories are recommended for review and are indicated with a red circle.
10. Following this is a breakdown of this information on a per question basis.
