Methods in my own Research

Preliminary validation of the survey instrument, data collection, data analysis and further validation of the instrument progress in a cyclic fashion. Student responses to open ended questions are used both as qualitative data in their own right, and to refine the questions for future use. See also my website on conducting rigorous educational research.
