A study of the relationships between students' questioning and learning styles is being conducted on data collected in two university semesters with a sample of 300 students. This report discusses the results of case studies looking in depth at four of the students. These were involved in further data collection through written and oral questions, interviews and classroom observation experiments. The main aim is to unravel the interrogative bases of the students' learning by looking at the quality and quantity of questions they ask. This means that among other characteristics, the nature and the deliberative or spontaneous use of questions by the four students were investigated. It was possible to distinguish question-askers by tallying their questions. Their learning styles were characterised using Kolb's Learning Styles Inventory. The study also allowed for snapshots of how particular learners shape questions. Looking at the way in which these questioning styles fit with their orientations to learning, and how this drives learning, informs what teaching might best then ensue.
