Asynchronous communication, offered by the website, was utilized to a limited extent. These preferences reflect student desire for immediate answers. In a third small-scale study, Gorsky, Caspi, and Trumper (2006) investigated the dialogic behaviour of campus-based college and university students learning physics and chemistry in large and small classes. This study was carried out in order to compare the dialogic behaviours of campus-based students with distance education students.

Therefore, most students preferred collaborating with peers rather than with the instructor. 5.
