What Makes Mid-Tertiary Mathematics Multiple Choice Test Items Difficult: Task Numbers or Cognitive Levels?
The researchers ascertained the linear relationship between any two Multiple Choice Test (MCT) items’ facility indices (z), cognitive level (x) and “task numbers (y). A 50 itemed multiple choice test was administered on a random sample of 226 NCE students who offered a General Studies Education (GSE) mathematics course. The test has a reliability coefficient of 0.92. The sampled students’ responses were scored. The estimates of correlation coefficients: rzx = - 0.33, rzy = - 0.33 and rxy = 0.87 were obtained and found significant (p<0.05). From the results, cognitive level and task numbers could provide a bridge between Classical Test Theory (CTT) and Item Response Theory (IRT).
