Conclusion

The findings here suggest that simple interaction, absent of structure and
leadership, is not enough.We need to have a qualitatively richer view of interaction.
There is a strong need to study the qualitative nature of online interaction
in terms of teaching and learning approaches. The position here is
that the reflective and collaborative properties of asynchronous, text-based
online learning is well adapted to deep approaches to learning (i.e., cognitive
presence). Further study is very much needed to understand the nature
of online interaction that will support high levels of learning.
