ab: Summary: We develop a model, which we call the quality index (QI) model,
for measuring how good a mathematics question is. Based on the
literature on mathematics assessment, we develop a theoretical
framework, using three measuring parameters: discrimination index,
confidence index and expert expectation. The theoretical framework
forms the foundation on which we form an opinion of the qualities and
characteristics of a good mathematics question. The QI assigns a
quantitative value to the quality of a question. We also give a visual
representation of the nature of a question in terms of a radar chart
using the mentioned criteria and illustrate the use of the QI model by
applying the measure to question examples, given in each of two formats
‒ provided response questions (PRQs) and constructed response
questions (CRQs). A greater knowledge of the quality of mathematics
questions can assist mathematics educators and assessors to improve
their assessment programmes and enhance student learning in
mathematics.
