It is apparently time to review what ‘transactional distance’ means:

Wikipedia tells us:

Transactional distance theory was developed in the 1970s by Dr. Michael G. Moore, Distinguished Professor Emeritus of Education at the Pennsylvania State University. tells us:

The theory of Transactional Distance states that as the level of interaction between teacher and learner decreases, learner autonomy must increase.

When talking about distance education we are typically talking about a teaching environment where the separation between the teacher and learner is significant enough that special teaching-learning strategies and techniques must be used.

Even though there are clearly recognizable patterns, there is also enormous variation in these strategies and
techniques and in the behaviour of teachers and learners. Within the family of distance education programmes there are many different degrees of transactional distance.
