were unsure with whom they were speaking. This
may have prevented learners from participating ac-
tively in conversations. (Cobb, 2009) pointed out that
learners speaking to anonymous entities may feel un-
comfortable participating in such conversations. In
addition, delays in sending and receiving messages,
for example, due to a poor Internet connection, could
have affected the learners’ behaviour.
Thus, because of the previous shortcomings, we
may need to conduct a further experiment with more
realistic chat. We can, for example, make the learn-
ers contact each other and record the conversation be-
tween them. In addition, we can repeat the same ex-
periment, but take the initiative to discern how differ-
ent personalities will respond.
6 CONCLUSIONS
Because of the lack of physical interaction be-
tween learners in online courses, many studies have
suggested incorporating social elements into those
courses to prevent learners from feeling isolated. In-
teractions with teachers and other learners can be
achieved using chats, discussion boards and emails
(DeSchryver et al., 2009). However, some research
has claimed that some learners do not prefer to talk
to others, while others may get distracted because of
these interactions (Laidra et al., 2007). Some learners
may also feel insecure in online interactions (Tu and
McIsaac, 2002). Because of these varied responses to
social components, we designed this study to inves-
tigate how different personalities respond to existing
social components, such as chat.
The results from our study confirm the variation of
the effect of chat on the different personalities. Some
learners enjoyed using the chat. Some personalities
spent their time talking about off-topic subjects rather
than the course, while others preferred to build rela-
tionships and introduce themselves. This variation in
the response to the chat affected learners’ knowledge
gain and satisfaction. For example, Some personali-
ties are not expected to show any difference in their
knowledge gain and satisfaction either with or with-
out the social element, such as highly conscientious
learners. However, other learners are more satisfied
where there is a social element. Meanwhile, some
learners have less knowledge gain where there is chat,
such as the highly extrovert learners. These learners
have the highest number of messages. Most of their
messages are about topics other than the course itself,
for example: fashion, travel and sport. To enhance the
knowledge gain of these learners, we may need to ob-
serve the behaviour of these learners, and then direct
the conversation back to the topic itself. For example,
if the learners start to talk about an off-topic subject,
one might say, ’This is okay, but let’s talk about the
course’.
This study provides insight into the type and num-
ber of messages sent by different personalities. How-
ever, in this experiment, only a few learners with
extreme personalities were included. In addition,
there was a positive correlation between personalities,
which may have resulted in bias. In this experiment,
the learners had to take the initiative and start a con-
versation; as such, some learners chose not to talk.
Thus, we could not examine the effect of the chat on
them. Furthermore, the researchers responded to the
learners, which may have resulted in delayed or unin-
teresting responses. Thus, further studies need to be
conducted to have a better understanding of the effect
of social components on learners. In this study, we
used personality as a stable characteristic related to
individuals’ behaviour. However, there are other char-
acteristics that may be considered (e.g. learners’ ef-
fective state, mood and learning style). After building
a good understanding about what is needed and liked
by each learner, we can build a system that provides
a dynamic place for learners’ conversations. This can
be done by controlling and directing the conversation
for some learners or by encouraging some learners to
interact more with others.
