This study was an initial attempt to operationalise Moore's transactional distance theory by
developing and validating an instrument measuring the related constructs: dialogue,
structure, learner autonomy and transactional distance. Data were collected from 227 online
students and analysed through an exploratory factor analysis. Results suggest that the
instrument, in general, shows promise as a valid and reliable measure of the constructs
related to transactional distance theory. Potential refinement of the instrument and future …

Transactional Distance is a component of distance education that has yet to be given a
concrete definition or method of measurement. This project developed a method of
measuring Transactional Distance in web-based distance learning classes which derives
from a survey given periodically to students. This project examined an initial survey provided
for the purpose of measuring Transaction Distance and used that as a starting point to
develop a survey that more accurately retrieves relevant data.
