In this section the results of the student questionnaires, the use of discussion boards, and the assessment data are first discussed.
Two most successful clusters appeared to be learners who extensive and structured use of discussion comments.
Research on the use of discussion boards as a resource was conducted from 2008 to 2011 (Gregory 2015).
The research focus in this paper dealt with students learning online through the use of discussion boards, wikis and 3D virtual worlds.
The criteria for listening, speaking, reading, and writing, for example, examine the suitable intonation, skills of discourse, classification of reading articles by their attributes, and the proper use of discussion boards for students when practicing their writing skills.
But there are also problems related to the use of discussion forums in Internet-based treatments.
Differences in the level of use of these CAI applications (i.e., higher use of discussion forum vs. a tutorial) were also found for the " Perceiving/ Judging" dimension.
Proposed uses included signposting to self-help websites, use of discussion forums, email & Skype communications, and continued development of own software.
While an optional use of discussion forums was indicated by more than 75%%, mandatory integration of this tool was noted by less than 10%%.
Two case studies [ 28, 29] found significant improvements in knowledge acquisition (measured by students' final marks) through the use of discussion boards.
