Research Abstract

To examine the quality of our current Year IV (Nursing Administration) multidisciplinary
MCQ, T &F, and matching questions and to see if there was any relationship between the item
difficulty index and the item discrimination index values in these questions. Materials and
Methods: MCQ, T&F, and Matching questions in the study taken from Year IV student in the
nursing administration final examination were analyzed to obtain their difficulty and
discrimination indices. The examination consisted of 10 true/false, 10 MCQs, and 15 Matching
questions, items on topics drawn from different disciplines. The questions were first constructed
and vetted by the individual departments before being submitted to a central committee, where the
final selection of these questions was made, based purely on the academic judgment of the
committee. Results: the students who have high grades in the MCQs, T &F, and matching
questions they found no difficulty and distraction in answering these questions. The difficulty and
the discriminating power were found among the MCQ questions number 2, 3, 8, 7, while it was
found among the T&F questions number 8, 6, 10, 3, and in matching questions it was found
among the questions number 5, 4 respectively. There was a non significant positive correlation
was found between MCQ and T & F. While, there was a highly significant positive correlation
was found between MCQ, and matching questions. It also observed that there is a non significant
negative correlation between T &F and matching questions. Conclusions: MCQ items that
demonstrate good discriminating potential tend to be moderately difficult items, and the
moderately-to-very difficult items are more likely to show negative discrimination. T &F
questions were the very difficult questions with discrimination power ranging fi·om low to very
high. Matching questions were the easiest and low discrimination power and Jess distractibility.
There is a need to evaluate the effectiveness of our MCQ, T &F, and matching questions items.
